There are hundreds of pages of entries and discussion, so look at it to see what worked and what didn't! CHALLENGE RULES Given the scale of this challenge, everyone who completes the mission successfully gets a spot in the hall of fame. 1. No cheating, including the stock debug menu cheats, HyperEdit, kraken drives, or file editing. HyperEdit is allowed for testing but get rid of that H when you fly the real mission! 2. No part-clipping of functional parts (fuel tanks, batteries, crew pods, engines, science parts, SAS) into each other. It is okay to clip structural and non-functional parts, wings, and heat shields. 3. Any number of launches are allowed to assemble the ship in low Kerbin orbit (preferably below 100km, not a hard ceiling though, but do try to stay around or below 100km at most). All launches must be flown! 4. There's funding for one main ship only so all the crew, lander(s) and other stuff has to go to Jool as one big ship. Once the ship leaves LKO, it cannot obtain more parts or fuel unless it mines and refines the fuel itself. The ship can separate once in Jool's SOI. 5. Kerbals must be in a pod or cabin (no seats) for the interplanetary journey. Seats are okay for landing and flying within the Jool system. 6. One refueling mission is allowed in the Jool system if you run out of fuel, unless your ship uses ISRU. The refueling mission can only transfer resources, not parts, to your Jool 5 craft. This mission must actually be flown! 7. On all of the landings, the Kerbal must be able to get out and walk (or swim!) around on the surface. Make sure your ladders work! 8. Use Normal difficulty or harder, except, any ComNet settings are allowed including turning it off completely. 9. All the Kerbals have to arrive back to Kerbin surface at the end of the mission, happy and alive. You are allowed to optionally send up a craft to return them from LKO. 10. Mods / DLC: STOCK: only mods which do not add parts and do not change physics are allowed. This includes any informational, planning, visual, autopilot, or automatic functions. DLC: Any and all DLC made for Kerbal Space Program are allowed. MODDED: Use of most parts mods and certain game mechanics mods are allowed. You NO LONGER HAVE TO ASK if your favorite part pack is allowed! Some parts mods are prohibited. Please see below. Specific Mods: ENTRY SUBMISSION RULES 11. Submit your challenge as an imgur album, with good captions and descriptions, as a video or series of videos, or as a thread in Mission Reports. 12. Pictures or it didn't happen! Please keep the resources tab open, as well as show the informative windows from Mechjeb or KER if you use them. Take a picture of every important moment, including transfers, dockings, landings, stagings, and refuelings. For Jeb's Level, also take pictures of the science screen when you recover your craft. Alternatively, video submissions are a great way to show everyone your mission as well. These will help future participants to see exactly how you accomplished each part! CHALLENGE LEVELS 1ST LEVEL: one Kerbonaut lands on all the moons and come back safely. Low mass and low cost and low parts sub-challenges: with stock parts and physics, how low can you go and still accomplish the mission? NOTE: Low cost submissions may not utilize ISRU, or a negative cost would be possible. (Thanks @jinnantonix!) 2ND LEVEL: two or more Kerbonauts land together on all the moons together and come back safely. 3RD LEVEL: There's not enough time left for training one crew member to be an expert on all of the moons, so five Kerbonauts must go to the mission, with at least one unique Kerbonaut landing on each moon. JEBEDIAH'S LEVEL: collect as much Science as possible! Your score is the number of science points from the Jool system only, returned to Kerbin (not transmitted). Only stock experiments count for this! To score, take pictures of the science screen(s) when you recover the data. Otherwise, the rules are the same as 3rd Level. GATECRASHER / HONORARY MENTIONS: Missions completed the mission in spirit but didn't meet every requirement. ISRU: Use of ISRU will get a note ISRU on the entry description in the hall of fame. This includes stock ore harvesting and converting as well as mods such as Kethane and Karbonite. ISRU is allowed for any level of completion. GRAND TOUR: Not officially part of the challenge, but landing on all planets and moons in the Kerbol system in one mission will earn a GRAND TOUR note and the everlasting praise of all of Kerbal kind. Rule 4 is waived, but any Kerbals on the mission cannot return to Kerbin in between any landings and you still must follow the other rules. Additional optional information to help others see how the mission was accomplished: - Which game versions did you use? - What mods did you use, if any? - How many Kerbals are on the mission? - How many launches were needed to start your mission from Kerbin? - How much did your mission cost? - Did you needed a refueling mission? - Did you bring additional stuff like satellites, rovers, etc? - Share the delta-V information too, if you tracked it! ------------------------------------------------------------------------------------------------------------------------------ Well, now this big announcement is in the Kerbal News, all the public is excited about this mission and even the Government is watching! Now it's up to you, to the engineers and to the bravest and craziest Kerbonauts of all time! Completion Badge: Anyone who has finished the challenge can add this badge to their signature. The Low Mass Feather badge is available for entries in the low mass sub challenge. Hall of Fame 1st Level- - @Laie Video here. Used a smaller-than-you'd-expect rocket with a dedicated Tylo lander and a spaceplane shell that encloses the Vall-Bop-Pol lander to make the Laythe lander. A very well done mission with a great video. - @Stratzenblitz75 Video here. Used a completely reusable mission involving a tiny mothership which orbited Tylo and tiny landers that explored the system. I should also point out that no nuclear engines or ions were used in the mission. Truly impressive. - @Ultimate Steve Videos here and here. Used a single launch in career mode sending Val to many places in the system including Vall. Very impressive how quickly the mission was thrown together and carried out. - @IncongruousGoat Album here. A simple, single launch Jool 5 mission that only uses 42 parts! Very well optimized and well done. Good job! - @chargan ISRU Gif here. Used an ISRU shuttle and hopped from Kerbin, to the Mün, to the Joolian moons, to Duna, and finished it off with a glorious vertical landing at the KSC. Excellent job! - @GRS Album here. Used a massive, creatively named mothersheep that carried landers for Laythe and Tylo, landing on Vall and Bop (AND DRES!) by itself. As an added bonus, the lonely Dres was even visited, that doesn't happen very often. Amazing job! - @Challyss Album here. Used a brute force 5 meter launch booster with two 5 meter side boosters. Once in LKO used a vector-power stage to boost to an elliptical orbit, then used a rhino powered mothership to go to Jool, where it completed the mission. - @Superfluous J V ideos here. Used a single launch to send three Kerbals to the Jool system, where the ship parked in an elliptical Tylo orbit. From there a tug took the landers to their respective moons where they *wait for it* landed. The ship then fired all three Kerbals home safely. An amazing mission and equally amazing videos. - @Xurkitree Grand Tour Thread here. A surprisingly small mission that not only landed on all the Jool moons, but also every other planet and moon in the system. The mission sent a craft out to Eeloo, which landed and returned to Jool before heading home. Once in orbit Derton was picked up by a recovery rocket and landed safely back on Kerbin. Outstanding. ISRU Video here. I don't even know where to start, Xurkitree didn't just do a Jool 5 in this mission, they did it twice. A large SSTO ISRU craft launched and refueled on Minmus before gravity assisting its way to Jool where it completed the landings and then returned to Kerbin, WHERE IT RELAUNCHED and then detached a small non-ISRU craft which carried out the landings again. A fun note was when the Laythe lander landed by computer control while the Kerbal parachuted down. Great job on your fourth Jool 5 submission! - @dvader Album here. A single launch using only chemical engines. Used several gravity assists to make the trip to Jool cheaper in terms of delta-v. Used a small but capable plane for Laythe, and a donut lander for the other moons (with extra fuel for Tylo and Vall.) Overall a very optimized mission, complete with a near KSC landing. - @fulgur Album here. A very small and well optimized mission with a smaller-than-you'd-expect mothership. Ions were used to scoot Jeb and Vall about the system to the various moons, and then left as the small mothership made its way home, getting into Kerbin orbit with only forty m/s of delta-v remaining. (Talk about close margins!) The crew were returned safely by an Aether SSTO. - @Pro100kerbonaut ISRU Mission report here. Used an SSTO spaceplane to go to Minmus to refuel, then flew off to Jool. This mission is the most impressive in how it handled the Tylo landing. Not only was the landing done using the SSTO, but it came directly from Vall without refueling at Bop or Pol. The landings were all completed flawlessly, but was destroyed in a crash landing back on Kerbin. The pilot survived though, and any landing you can walk away from... - @dnbattley Album here. A direct ascent mission to all five moons, starting with Pol and Bop, then Vall, Tylo, and finally Laythe. The tensions on this mission were very high, as Jeb began his Tylo descent on a NERVA powered craft with a TWR of .9, managing to get it above 1 just in time to pull off the landing. From there Jeb flew to Laythe where he somehow missed the ocean (this might be a KSP first) and used the craft's jets to push it into the water for an ocean launch. After struggling back into orbit, Jeb flew by Tylo back to Kerbin, using a Duna aerogravity assist to get the right trajectory (ARE YOU SERIOUS?) Upon returning to Kerbin he was able to sneak in a Minmus landing. This mission is without a doubt one of the more Kerbal ones submitted, complete with Jeb gliding the final stage down to Kerbin with his EVA chute. - @EveMaster Grand Tour, ISRU Thread here. Additional album here. EveMaster managed to complete the Jool 5 challenge with an ISRU craft, utilizing the power of two mammoth engines and a detachable spaceplane. Also went the extra few million miles and completed a grand tour! Both Bob and Jeb were on this mission, however Bill stayed behind on Eve, so only Jeb is being considered for this entry. Regardless, an excellently executed mission. - @ManEatingApe, @Jacke, @dvader, @Muetdhiver, @Rakaydos, and @Pds314 Mission thread here. What these users have completed is the first community Jool 5 mission for this specific thread, possibly the first ever. Furthermore, this mission was done in a 'caveman' style approach, meaning no maneuver nodes, tier one buildings, and launch mass restrictions. These restraints meant the main ship was built over multiple launches. The landings were carried out by a plane and three identical landers, which carried Jeb to, around, and back to Kerbin from the Jool system with excruciating precision. I highly suggest checking out this mission's thread, it's one of a kind! - @Space Nerd Album here. Using a long nuclear mothership, Jeb and Malvis conquered the Jool system in a surprisingly easy manner. An off-center Bop/Pol lander was docked onto the side of the mothership, leading to one of the more interesting mothership designs. Jeb took Laythe, Tylo, and Vall, and Malvis handled Bop and Pol. Once all the landings were done, they flew back to Kerbin and used a 10 meter heat shield to slow down and splashed into the ocean. - @ralanboyle Video here. Using a single brute force launch, a main station of sorts was put into Jool orbit,. From there a Laythe-plane was released, and upon returning from Laythe, a lander/fuel tank combo (and an extra part for Tylo) took on Tylo, then Vall, then Bop, then Pol. They forgot to put a flag on Pol, but who cares. Also, the lander was able to return to Kerbin all by itself. Quite the capable craft I'd say. The mission is edited into a very nice video, and I suggest giving it a watch if you've got the time. - @Carbonjvd Album here. Using the incredibly stylish IPV Excelsior spacecraft, Tridous Kerman flew to Minmus to refuel, where she picked up two more crew members in Minmus orbit. From there they flew to Jool, where they refueled at Bop. After the tanks were full, they hopped to Pol, then Tylo, then Bop again, then Vall. From Vall the crew hopped back to Bop for more refueling, then flew to Laythe. After converting stored ore into liquid fuel, the crew touched down on an island, then (you guessed it) flew back to Bop! (for more fuel) From this final Bop landing, the Excelsior returned to Minmus where it all began, then safely touched down on Kerbin. A stylish landing for a stylish craft. - @camacju Grand Tour. Album here. This mission is impressive as it not only visited the five moons of Jool, but also every other landable surface in the Kerbol System. The Jool portion of this mission was completed after the mothership completed the Eve portion, then used gravity assists to get to Jool. A Tylo assist put the ship on course to aerobrake at Laythe, and after landing on Laythe the lander was then reused for Tylo. The other moons were completed using a smaller lander, and the brave Kerbonaut landed back at Kerbin after quite an exciting trip. Video here. A very well edited video of a Jool 5 mission which used only liquid fuel! Launching from the runway as a spaceplane, the craft flew up before staging its rapier engines and continuing to orbit on nerva-power. The Laythe landing was done using a smaller spaceplane, and the rest of the landings were done using a very impressive lander which used only 1 nerv engine to land on all the other moons, including Tylo! The lander also served as a trip home and as a heat shield so that the brave kerbonaut could parachute to safety. This mission is beautifully summed up in the video link, and I highly suggest checking it out. A truly unique mission! Video here. Another liquid fuel only mission! This one utilized multiple relaunches of the same spaceplane to put multiple fuel tankers in orbit. From there, the craft departed for Jool after some gravity assists and once again demonstrated the unusual, difficult, and impressive use of a nerv-powered Tylo lander. The video this mission was edited into is nice and tidy as well, and I suggest watching so you can see all the work that went into it. Video here. And yet another Jool 5 mission, but this time with only one engine! A cargo spaceplane with a single rapier made multiple launches to place several fuel tankers into orbit before flying a gravity-assist-utilizing course to Jool. Once in Jool space, the Laythe landing was conducted first, and then the plane ditched its outer shell so that just the rapier engine and a few fuel tanks remained. The craft then docked to a fuel module in orbit and flew to Vall, landed, then went to Tylo where a dedicated fuel drop-tank was used with what I'll dub "backflip staging". From there the Pol and Bop landings were done, with fuel to spare. After a fiery return to Kerbin, the brave Kerbonaut, Wildard, paraglided safely into the ocean. I recommend giving this video a watch, because it's short, to the point, and an amazing display of Kerbal engineering. Grand Tour. Video here. This mission is truly a record breaker, as not only was it a Jool 5, but it is the lowest mass Grand Tour without ISRU record holder, with a take off mass of 14.447 tons, less than a Mammoth engine! To focus on the Jool 5 portion of the mission, a spaceplane made a bouncy, thrash-flippy landing, then a tiny tiny lander was used to tackle Tylo. Pol and Bop were handled by a small ion lander, and Vall was handled by a lander so small it looks like a pancake. You should definitely give this mission's video a watch, as words cannot truly describe just how insanely optimized this mission was. - @Goufalite Video here. This mission began with the assembly of a main mothership in LKO. Once complete, the ship cruised to Jool where it used gravity assists to achieve orbit. From there, the spaceplane was deployed to Laythe, but missed its target island. Never fear! The spaceplane had such high performance it was able to fly to a nearby island. Once back with the mothership, the SSTO was drained and detatched, and a capsule on its nose was undocked and docked to the Tylo lander. The Tylo lander used 2 aerospike engines to blow its way to the surface, and the final stage of the lander redocked to the mothership to be reused as the lander for Vall, Bop, and Pol. After visiting Vall and Pol, the lander flew by itself (and out of connectivity range) to Bop, where it landed and returned to Pol all on its own (Goufalite found this method was more fuel efficient). After returning to the mothership at Pol, a Tylo gravity assist sent the crew home, and both safely landed only 50 kilometers from the KSC. This mission made me nostalgic for my first Jool 5 mission, which in turn makes this mission special to me. Nice job, @Goufalite. - @king of nowhere Grand Tour. Mission thread here. This mission was done using Kerbalism, and an absolute UNIT of a mothership. Appropriately named the DREAM BIG, this ship conducted the Jool 5 challenge with dozens of farms, radiation shields, and drop ships to keep itself self-sufficient. Fighting food limitations, mod issues, solar storms, insanity and radiation damage, the crew of DREAM BIG flew throughout the entire Kerbol system planting flags on every world. The mission thread is an entertaining read, and has a video tour of the DREAM BIG spacecraft, which I highly recommend you check it out. I congratulate @king of nowhere on completing the mission, and for not losing their sanity in the process! Mission thread here. This mission was done with tremendous build constraints, and done entirely in a no-contract career mode save. Each launch was limited to 20-25 tons, meaning it took dozens of flights to finish the main ship, the Marco Polonium. The ship used many cost and weigh saving methods, including using the Laythe lander as a stage on Tylo, and by using claws instead of docking ports in some cases. The mission also visited Duna, Ike, Eeloo, Dres, and Eve (orbit) as well. This mission is one of the most entertaining ones I've reviewed (along with one of the most optimized) and I highly recommend giving it a read. Mission thread here. This mission was much like @king of nowhere's previous two in the sense that it involved Kerbalism and self-imposed building constraints. The result was a Jool 5 mission designed and flown to be as realistic as possible, and done with a maximum LKO mass of 140 tons. Bill and Bob took the Economic Downturn and its support craft to Jool and visited Tylo first, using the Seated Man lander, then made way for Laythe to deploy the Sole spaceplane, each accompanied by the space tug Right Answer. Sole's upper stage was reused as a Vall lander, while Seated Man's upper stage was used to land on Bop and Pol. For the inner three moons, great care was taken to limit the radiation damage incurred on the crew, with Bill being irradiated all the way to 95% upon his return to Economic Downturn. The return trajectory had to be tweaked a few times to prevent the capsule overheating, but Bill and Bob ultimately prevailed, and returned to Kerbin with nearly 500kg of samples. This mission is one of the few anxiety inducing submissions due to the challenges imposed by Jool's radiation belt. If you are a fan of gripping mission threads, I suggest giving this one a read. - @Lt_Duckweed Video here. This Jool 5 mission is notable for three reasons. Firstly, it is fully recoverable. Secondly, it only uses two engines, being the nerva and rapier. And thirdly, it was edited into a masterpiece of a video. This mission began with a launch just west of the KSC, and made a direct transfer to Jool. Upon Jool arrival, the elegently designed craft deployed a nerva-propelled lander, which performed the Tylo landing. After refueling at the main ship, the lander then visited Vall, Bop, and Pol with refueling trips to the main ship in between. The lander then returned to the main craft, which transfered to Laythe, completing the final landing. The craft then returned to Kerbin and came to a stop on the KSC runway, returning with it every part it launched with. I must repeat the high quality video the mission is edited into, and strongly suggest giving it a watch. - @bwest31415 Album here. This mission began with the launch of a long thin rocket which was followed by a normal transfer to Jool. Upon arrival to Jool however, inflatable heat shields were used to induce a Joolian aerobrake, a maneuver I've scarcely seen used since the addition of reentry heating to the game. The first landing to be done was Laythe, and the final stage of the lander was used to land on Vall and Tylo. The lander then left the main ship behind and traveled to Pol, then Bop, then back to Kerbin all without refueling. Jeb landed safely back on Kerbin after a toasty aerocapture, and exited the pod to take in a nice mountain view. - @18Watt ISRU, Thread here. This mission was done as both a Jool 5 and a Kerpollo submission. The mission began with a brute force launch and direct transfer to Jool. The mothership used wolfhound engines, which was good for TWR but slow when the ship was fully fueled. The ship flew first to Tylo, and after landing, the Tylo ascent stage would be reused for later landings. Next, the ship went to Bop to refuel, then to Laythe, where a staged spaceplane returned the brave Kerbonaut to the mothership. Next Val went to Vall, then the ship went to Pol and landed, before returning the crew to Kebrin, who parachuted to the surface of one of Kerbin's icecaps. - @OJT ISRU, Thread here. This mission was fully reusable* (apart from deployed fairings but we couldn't decide if that counted or not) and landed every component of the main ship back on Kerbin upon finishing the Jool system's exploration. The mission began with three launches, one for the mothership, one for the lander, and one for the SSTO spaceplane. Due to unfortunate moon placements, no gravity-assisted captures were possible and a retroburn was conducted. From there, a surprise Laythe aerocapture was conducted, saving much needed fuel. After the Laythe landing, the main ship flew to Vall, left the plane in orbit, and then landed with the lander beneath it and refueled on the surface. Next up was a Tylo landing with razor thin fuel margins, followed by Pol and Bop. It is worth noting that this mission did not repeat OJT's previous Jool 5 mission's Pol refueling process, in which the lander did numerous trips to the surface to bring tiny bits of fuel up to the main ship. With the landings complete and plenty of fuel to spare, the ship flew back to Kerbin where it landed piece by piece, with the lander being launched an SSTO parachute module. An excellent mission, and no doubt a fine achievement. - @kspfreak Video here. This mission not only visited the moons of Jool, Bop's Kraken, and in a rather small vehicle, but also visited every other moon in the entire Kerbol System! This mission's video is a fun watch, and ends with a fun paraglide back to the KSC. A mini grand tour of sorts, and very well done. - @JeDoesStuff ISRU, Video here. An SSTO submission! Coming in with a mass at just under 30 tons, JeDoesStuff showed off an incredibly refined ISRU SSTO by flaunting it around the Jool System. Included on the spaceplane are subtle but clever features to aid in launching horizontally, such as Vernier thrusters on the nose to raise attitude during takeoff, as well as a large landing gear that is only deployed to angle the craft. I haven't seen the latter of those additions on an SSTO before, so I applaud the ingenuity! The video this submission is contained within is also very well edited, resulting in a brief, yet concise viewing experience. If you're looking for a fun video to watch, or to see a razor-thin-margin Tylo landing, then this submission is for you. Low Mass - @EvermoreAlpaca Video here. Mass of 6.2 tons. Spaceplane launch, gravity assists off Kerbin and Eve to reach Jool. Landed on Laythe with the same rapier used in the launch stage, returned to orbit with an incredible TWR, scooted over to Tylo where the most bare-bones Tylo lander I've ever seen was used to land on and take off from Tylo (saved fuel by having Bill push it to the top of the mountain), flew over to Vall where the landing was done using staged batteries and a single ion engine. The Vall lander (which was also part of the Laythe lander) completed the last two landings on Bop and Pol and returned to Kerbin using many more gravity assists before preforming an aerobraking, with Bill parachuting to the space center and landing atop the RnD. - @Alpaca Z Video here. Mass of 5.8 tons. Vertical launch using a whiplash ramjet engine, which was staged prior to orbital insertion. Resonant orbits with Kerbin and Mun assists were used to set up a KEKKJ gravity assiste route to save fuel. Spider engines were used in a two-stage Laythe lander design to save weight, and EVA construction was used to rebuild craft to negate the need for decouplers or rebuild the craft (or get away with only bringing one chair). Landings were otherwise routine apart from an incident on Tylo where the lander fell on its side, requiring an intuitive solution to rebuild the craft in such a way it could use redundant engines as support pillars. The video is very well narrated and goes into much more detail regarding the craft's design and flight plan, I highly recommend watching it to get the full picture of this mission. - @camacju Video here. Mass of 5.2 tons (Current Record!). This mission not only shatters the previous record, but does so with an impeccably made video. Launch mass was saved in numerous ways, one of which involved using tiny flags in place of landing gear for the horizontal KSC Runway takeoff. EVA construction was used to reassemble the craft(s) into what was needed at any given point during the mission. The vessels flown and techniques used are difficult to describe, so I highly encourage a watch of this mission to see some of the best of Kerbal engineering. - @camacju and @Ultimate Steve Grand Tour, Video here. Mass of 7.6 tons. This is a meticulously crafted and borderline perfectly executed low mass mission. This was not only a Jool 5, but also an entire grand tour weighing not even 8 tons! The video's excellent editing allows it to speak for itself, and I highly recommend you watch this mission to see perhaps the greatest low mass mission in the history of KSP. Low Cost - @jinnantonix Video here. 34,663 funds. The thread's first low cost submission! Using a low cost launch vehicle and a K-E-K-K-J flyby route, the mission put Val and a fuel-tanker station in elliptical Laythe orbit. From there one lander tackled Laythe, and another tackled the other four moons, with an extra few stages for Tylo. It is worth mentioning that this mission used no electrical charge and relied entirely on engine gimbal and some RCS to steer. On the way back, a double Eve flyby helped slow down, so an aerocapture could be done at Kerbin, where Vall proceeded to parachute onto the VAB. - @camacju Mission here. 24,070 funds. This mission used a SRB powered launch stage and a terrier powered transfer vehicle to get the landers to Jool (after numerous gravity assists). A dedicated Laythe lander tackled the ocean-world, while a multi-stage Tylo lander tackled the rest of the moons, and returned the brave Kerbonaut Wildard Kerman to Kerbin. Before heading back however, the new space-construction method was utilized to steal a solar panel from the transfer stage, marking the first time this creative form of staging has been used. Mission here. 17,635 funds (Current Record!). This mission is a more stripped down version of @camacju's previous low cost mission. This mission featured a visit to Laythe's ocean floor, and utilized eva construction to manually remove empty fuel tanks from the mission. Additionally, eva fuel tanks were used to refill the brave kerbonaught's jetpack to enable fuel savings by extended jetpack use. Low Parts - @bayesian_acolyte ISRU, Album here. A small, single stage craft comprising of 31 parts. Bayesian_acolyte said there could have been some part count improvements, but even without it the mission still did so much with so little. This mission shows just how far ISRU can be stretched, especially with that Tylo landing. - @Majk Thread here. A simplistic Jool 5 mission consisting of only 30 parts . The mission began using a very basic launch stage, and flew to Jool using a long nuclear ship. Lander reuse enabled part count savings, and usage of the nuclear ship as an ablative heat-shield helped return Val to Kerbin's surface in one piece. - @Majk Video here. Easily the most simple Jool 5 mission completed to date, accomplished using only 9 parts (Current Record!). This mission started with the 9th part, an RTG, stowed inside the command pod before installing it in orbit. It is also worth recognizing that a clever method of timewarping in the tracking station enabled refueling to take place while utilizing only a single RTG. The submission takes the form of a short, concise, and wel narrated video, and I highly encourage giving it a watch. 2nd Level - @jinnantonix ISRU, Album here. Used a big launch with a self-refueling vector-powered lander that made multiple Laythe landings and mined ore from every moon. Two kerbals were landed on each moon and the lander was recovered at KSC. - @Kerbolitto ISRU, Album here. Excellent mission done using two space shuttles capable of refueling on moons. Absolutely amazing job. In all things I ever thought I would see happen in KSP, a space shuttle landing on Tylo was not one of them. - @Marschig ISRU, Videos here. Not one, not two, but three ISRU planes flew to Jool and to all five moons on both the 3rd and 2nd levels. The SSTOs also visited Duna and Minmus in their missions before landing back at the KSC. Truly exceptional. This is the first time I've seen three Jool 5s all submitted at one time! - @PhoenixRise86 Album here. Used a mothership for the first part of the mission, then resorted to ions to get to Ike and Minmus, then safely back home. Also, this is the first 2nd level mission to not use ISRU. - @GRS: Album here. The highly anticipated Sheep v2 did not disappoint, and went above and beyond by visiting not just Jool's moons but also Kerbin's and Dres. Used massive nuclear boosters to get around the Jool system and the Tythe lander to get two Kerbals on every moon and Dres, before using the Sheep v2 to land the entire crew on Minmus and Mun. Spectacular! - @Xurkitree ISRU Video here. This modded mission utilized ISRU, a nuclear mothership, and eight aerospikes to land on all five of Jool's moons with Cerdrin and Lodous Kerman. Returned the lander and mothership to LKO where a separate rocket retrieved the crew. I highly encourage watching the video submitted, it is excellently edited and the music supports the awe of the mission. - @QF9E Thread here. This mission used a blunt-force approach by lifting off on a powerful launch stage, and made quick work of Jool's moons. The moons were all visited by one lander, which dropped various attachments that helped it land on some of the bigger moons. At the end of the mission, the three brave kerbonauts safely touched down in the ocean, and a BFR style spacecraft recovered the remains of the lander in Kerbin orbit for historical preservation. Truly an impressive mission indeed! - @Mars-Bound Hokie ISRU Mission here. Using the Anubis II SSTO, Tancan, Fernal, and Kenby Kerman flew to Minmus to refuel, then blasted off for Jool. After touching down on Laythe to refuel, the crew went for Bop, then to Tylo. After landing with no liquid fuel to spare, the Anubis II was refueled, then launched for Pol. After a risky auto-piloted landing, the ship refuel before bounding to Vall, where the crew had a group picture. Heading back to Kerbin, a mix of brute force and aero-braking was used to get the trajectory needed to get back to the KSC, and then the crew refused to ditch the plane and pulled off the legendary runway landing. - @king of nowhere Mission here. "And so I completed the Jool 5 in day 383, 1 hour and 9 minutes of a new career" are the words typed by @king of nowhere at the end of the mission thread, and fundamentally capture the astronomical accomplishment documented within it. In a career save speedrun, it was decided to focus on a Jool 5, and the mission was optimized for time rather than mass or cost. The amounts of delta-v put into each maneuver to achieve bullet-like trajectories around the Kerbolar and Jool systems is simply jaw dropping. Over the course of the flight, the La coscienza di xenon and its landers managed to plant flags on all 5 moons within a 12 day window, which I don't believe has ever been done before. If you wish to see the chronicles of a one-of-a-kind, record setting Jool 5 mission, the flight of the La coscienza di xenon is the mission thread for you. Grand Tour Mission here. @king of nowhere's second Kerbalism Grand Tour, but with radiation shielding 3 times less effective, bugs, life support issues, frantic crew members smashing fuel cells and dumping food overboard, and so much more! This mission chronicles the Nail Bolt on its tour around the solar system, finding monoliths on every world and making it back in roughly two decades. This mission thread covers the begins, rebeginnings, redesigns, quick fixes, and compromises that took place during the Bolt's journey not just to Jool's 5 moons, but to every other surface as well. This is one of the most thorough submissions the challenge has seen, and is a great resource for those considering Kerbalism entries of their own. - @Lyra Mission here. A single launch mission! Using a spaceplane for Laythe, a notably slim Tylo lander (with a reusable upper stage for Vall), and an ion lander for Bop and Pol, this mission was a pleasant, self contained romp around the Jool System. One unique aspect of this mission I've seldom seen elsewhere was the use of claws on the nuclear mothership's outer hull. This allowed the landers to not need docking ports and attach to the hull like barnacles. A very clever, mass saving decision for the landers for sure! 3rd Level - @iAMtheWALRUS Grand Tour, ISRU, Album here. Used SSTOs to launch the mission and used moon hopping to get around the Kerbol system. Very nicely done. Also, first 1.4 submission - @sturmhauke Album here. To put it in the words of the pilot them self; "A mostly reusable mission to all 5 of Jool's moons. Single launch SSTO carrier drone, with a separable mothership and 5 landers." Very well done and efficient mission. Used fuel cells to power ion crafts for Bop and Pol, sent a plane to Laythe, and conquered Tylo with a rocket lander. - @mystifeid Album here, ISRU. Used two launches to put a mothership and a universal lander into orbit. Then used left over launch stage to boost to Jool and then around the system until it ran out and was staged at Tylo. Bob landed on every moon, accompanied with a different Kerbal for every moon. Very nice mission, and even had the added bonus of a near KSC landing. - @PhoenixRise86 Album here. Used a single launch of pure rocketry, no jets, ions, or nukes used in the entire mission. This mission did the Jool 5 mission in style, with some of the most interesting landers I've ever seen, including an aerospike Laythe plane. - @Marschig ISRU, Videos here. Not one, not two, but three ISRU planes flew to Jool and to all five moons on both the 3rd and 2nd levels. The SSTOs also visited Duna and Minmus in their missions before landing back at the KSC. Truly exceptional. This is the first time I've seen three Jool 5s all submitted at one time! - @jinnantonix ISRU, Video here. Of all the Jool 5 missions I have seen in this thread so far, none treat their Kerbals better than Jinnantonix has. The craft was modular in design and split into several different arrangements for various landings, and came with a gravity spin for deep space transit. Very considerate, and very awesome. - @Grogs Album here. Two launches to build the main ship in orbit, one crew launch for realism. Used a giant transfer stage to get the landers to Jool. Chemical engines pushed the landers about the Jool system, with nine Kerbals in total being involved in the mission. Once the landings were completed the mothership returned to Kerbin where a fourth launch collected the Kerbals and returned them safely to Kerbin. - @Pipcard ISRU Thread here. A well executed, eight Kerbal mission with one of the longest ships I've ever seen in this game. Excellent mission that toured the Jool System in an engaging thread. Mission was assembled in multiple parts, flew to Jool, landed on the moons (being sure to refuel on Bop and Pol when needed), EVA jetpacked off Tylo, and the crew was returned to Kerbin by a separately flown space plane. - @Kerbolitto ISRU Mission here, here, and here. Kerbolitto's second submission! Using a space shuttle with several surface experiments, a crew of eight explored the system. The Tylo landing was done with perfect margins, landing with no fuel left! This craft may also hold the record for lowest TWR launch of Bop in history, and an outpost on Laythe with a mini-plane was even constructed. Bob chose to stay behind and man the base while the crew returned home. Excellent end to an excellent mission! - @Ksp Slingshooter Album here. Assembled the main ship using multiple launches, then flew to Jool, settling in an elliptical Jool orbit with some help from a few gravity assists. From there the landers detached and flew to their moons, one by one and completed their landings. Due to some unexpected occurrences at Laythe, the Vall lander swooped in and rescued the Kerbal, taking both back to the mothership. Without enough room in the command pods for everyone, two brave Kerbals rode back to Kerbin on ladders, detaching and re-rendezvousing during timewarp. A rescue craft was launched, and met the mothership just in time, with only three minutes to transfer the Kerbals before a fiery re-entry. Truly a Kerbal mission! - @RoninFrog ISRU Thread here. Using the gloriously huge HMS Sauron, Jeb and 16 friends took to Jool in this massive SSTA. First they stopped at the Mun, then flew to Pol, then Tylo, then Vall, Laythe, and finally Bop. On the way back to Kerbin, time and fuel and the positions of the planets made a Duna landing prove itself most useful, before heading back to the Mun, and finally, back to Kerbin. This 1 stage mission has some amazing screenshots in its thread, as well as most amusing comments for each picture. If you're wanting to learn more about an ISRU approach, I suggest giving this mission a peak. - @OutInSpace Video here. Using a total of eight launches, this mission's mothership was constructed methodically, complete with an enormous pair of transfer boosters. After heading to Jool directly, the mothership flew to Tylo, Vall, and Laythe by itself, and sent an ion craft to Bop and Pol instead. After numerous attempts, the Laythe plane was finally able to show what it could do, and the 5 crew returned to Kerbin orbit, where they were picked up by a landing craft. If you want to see the nitty-gritty maneuvers used during a Jool 5 mission, I suggest you check out this mission's video. Its editing and methodicalness make it an unintentional flight-tutorial for getting to Jool. - @Entropian ISRU Mission here. Using a 5 meter tank with 5 meter tanks strapped on the side and a large cluster of mastodon engines, the craft rocketed off the pad to Minmus, where it refueled and went off to Jool. Landing on Laythe proved to a close call, with ZERO delta-v remaining upon touchdown. From there the ship bounced to Vall, Tylo, Pol, and Bop, before making a rough splashdown on Kerbin. It is worth noting that the crew did forget to put a flag on Bop. However since every other mission criteria was met and the craft was landed on Bop it is still being counted. - @GRS Grand Tour. Mission here. This time with the Sheep v4 the Jool moons were visited again, along with 60 other destinations! Relying heavily on ion power, landing after landing was accomplished visiting worlds close to the sun, around Jool, and even outer dwarf planets. So many worlds were mentioned that the Jool 5 portion is only a tiny fragment of the overall mission. There is genuinely too much in that mission to describe here, so I highly suggest you check out the most expansive sheep yet's thread! - @s_gamer101. Mission here. This mission began with the launch of an enormous reusable launch system that placed the main ship in orbit. A trip to Jool ended with a fiery aerocapture above Laythe, where two of the crew members took a small spaceplane to the surface. After a tricky fuel situation in which drop tanks were accidentally kept as huge pieces of ballasts, the Tylo tug was used as an extra stage to boost the main ship. This proved to be enough delta-v, as once the landings were completed the ship cruised back to Kerbin, where they parachuted safely to complete the mission. - @AlpacaMall Mission here. This mission began with the launch and orbital construction of the KSS-J "Orca". Engineer construction added fuel lines and removed unneeded RCS thrusters, and the craft departed for Jool with a reusable lander upper stage, with lander stages for Laythe and Tylo. The landings were completed in the following order: Laythe, Tylo, Vall, Pol, Bop. From Bop, the Orca was left to serve as a relay station while the crew module left for Kerbin. The vessel landed with all the crew and 23458 science. - @BeanThruster Album here. This mission began with the launch of Vapidity, the mothership used during the mission. Instead of going to Jool, Vapidity made its first flight to an E-class asteroid so it could refill all of its fuel tanks (it launched almost empty to save weight). After flying to Jool, the first landing took place on Tylo, before leaving the engine nacelles in case later refueling was needed. Next, the last stage of the Tylo lander was used to land on Vall, then the lander flew solo to Bop where it awaited the rest of the ship. Vapidity took the time to take a spaceplane to Laythe, then went back to low Tylo orbit to refuel. Vapidity met the Vapidlander at Bop, conducted the landing, then went to Pol to do the same. Vapidity returned to Kerbin before the crew landed using the Laythe spaceplane. In total, the crew collected 20113.6 science. - @RuBisCO ISRU Album here. This mission began with a lot of mainsail engines to push the main craft into orbit, and delivered not one, but seven Kerbals to the surface of each moon. The first visit was Pol, where cleverly built piston legs kept the refueling craft perfectly level. Next was Bop, then Vall, then Tylo, where a rover and lab were brought to the surface and returned to orbit (except Tylo where it got left behind). For the Laythe landing, the crew took down a spaceplane, as well as a helicopter and a floating lab with plane-refueling capabilities. The helicopter was used to collect science from the local area, and after being refueled, the plane returned to orbit. After the main ship was refueled on Pol, the crew returned home. - @18Watt ISRU , Mission here. This mission is nearly identical to 18Watt's previous submission, but now has accommodated a unique Kerbal for each moon, bumping it from a 1st to a 3rd level submission. Main ship refueled on Minmus before heading to Jool, refueled on small moons, and pilots Val and Billy Bobfurt flew each unique specialist to their respective moons. - @Krazy1 ISRU, Album here. This mission was done with the Principia mod, which makes gravity and orbits behave more realistically. The spacecraft used was the "2 by 4", named after its two mammoth engines and four nervs. First the craft launched to Minmus, then visited a passing asteroid, then went back to Minmus to refuel, then shot off to Jool. After the Laythe landing, there was some trouble getting to Vall due to orbital issues. After Vall came a very bouncy Tylo landing, which was followed by a Pol landing, and then a Bop landing. It is worth noting that Bop is orbiting retrograde in this mod for orbital stability. After completing the landings and experimenting with weird orbits, the 2 by 4 traveled home, refueled on Minmus to prep for landing, and then touched down safely on Kerbin with its crew of 5. ISRU, Album here. This mission utilized an orange and gray aesthetically pleasing spacecraft. Once launched into orbit, the craft refueled on Minmus, then shot off to Jool where it landed on Vall, then flew to Tylo where it performed this landing, before nearly burning on Laythe, then finished up with Bop and Pol. Upon returning to Kerbin, some excess ore was turned to fuel to save weight, and the crew splashed down 10km from the KSC. - @Kimera Industries. Mission here. This mission's mission thread chronicles the Avocado on its journey to Jool's moons and back, using appropriately named components and landers. Due to its nuclear propulsion, the escape burn was split in two, though did not go gently into that good night, and upon arriving to Jool, took use of a convenient Tylo assist to go almost directly to Laythe. From Laythe, a lander was dispatched to Vall and Pol, then the entire ship reunited and migrated to Tylo where the landing was achieved on the fifth try. Next came Gilly 2.0 Bop, where an interesting SPOILER was discovered. Upon returning to Kerbin with little to no time for caution, the cargo container and its draggy friends kept the craft from overheating during airbraking, and the crew landed to live another day. Jeb's Level - @Xurkitree Grand Tour, ISRU Album Here. Collected 19,711.3 science from Jool on a girl's night out mission with no lack of gravity assists. A note from the author said that the mission greatly improved their skills in KSP and proved that fact well with the insane gravity assists they pulled off. Also first Jeb's Level on the new thread yay! - @ManEatingApe Video here. And here. And here. And here. And here. And here. Collected 16,532.0 science from Jool. There isn't anything I can say about this mission except you need to see it for yourself. Exclusively low tech was used, and collected in space science from all biomes. This mission did the near-impossible, with primitive parts, and landed all Kerbals safely back on Kerbin. - @SolarAdmiral Video here. Collected 42,296 science from the Jool System. Single launch on a cluster of three meter parts, before heading off to Jool. Started with Laythe first, landing using a floating platform. Science was collected with a small jet-powered boat. Next stop was Tylo, where a rover was used to collect science from many biomes. On Vall one landing was done, and a hop added to it before heading to orbit again. Numerous biomes collected from Bop and Pol by hopping around in their low gravities. Direct shot home and landed all seven Kerbals to tell the tale. Absolutely astounding mission! - @jinnantonix ISRU Video here. Collected 82,510 science from the Jool System. Single launch, one much smaller than you might expect. Used a plane to gather large amounts of science from Laythe, dove into Jool's atmosphere, grabbed science from almost if not everywhere, and even managed to use the Laythe plane as the final stage on the Tylo landing. Had an artificial gravity system to facilitate the kerbals, and landed back at the KSC. Honestly jinnatonix managed to do so much in this video I can't describe it all here so I suggest you just watch the video. Amazing job. - @GRS Album here. Collected 28,643 science from the Jool System. The long awaited Sheep mission that satisfied both the Kerpollo and Jool 5 requirements led by Simone Kerman that explored the Jool system and returned home Apollo style. The mission had a heavy launch and went to, around, and from Jool using a massive nuclear stage. The usage of the Scifi visual pack gave the mission a unique look as it took science from every moon (including Jool's upper atmosphere!) in style. Incredible. - @Jim123 Video here. Collected 8780.9 science from the Jool System. Single giant launch put a large nuclear mothership in orbit. Flew straight to Laythe where the landing was completed with a dual stage to orbit (and Jeb's jetpack). From there the crew went to Vall and landed, before heading to Tylo and dropping one of the most Kerbal looking Tylo landers I've ever seen to the surface. After Tylo biome hopping was used on Bop and Tylo, before a pair of service modules detached and went back to Kerbin, boosting each other home where the crew landed. Nice video. - @jost ISRU Album here. Collected 16940.2 science from the Jool system. Flew to Jool using a long nuclear mothership. From there an ion ore probe helped find ore on every moon but Laythe for the rocket lander. Laythe used a three seat plane for the landing, and even found a geyser while on the surface. Landed on Tylo with 1m/s to spare before refueling, and landed everyone safely back on Kerbin after leaving the nukes in a graveyard orbit around Kerbin. Excellent! - @Beriev Album here. Collected 49430.1 science from the Jool system. This entire mission was done in a 6.4x solar system. Launched off the pad with an absolutely enourmous rocket, fittingly dubbed the 'Absolute Unit'. Used many kicks to get out to Jool, where the ship split up to tackle the moons. For Laythe and Tylo, ascent vehicles were landed separately, before the crew arrived on-surface. Later, both sets met up at Vall, then flew to Pol, then Bop, and then to Dres. After a fun journey, the Absolute Unit returned to Kerbin, and the crew landed safely. This mission has an incredible execution and design, as well as a well-captioned Imgur album. I highly suggest giving it a look. - @Pro100kerbonaut Video here. Collected 10238 science from the Jool system. This mission was done with a rather interesting, asymmetrically balanced ship, and had quite the bouncy ride. On Tylo parkour was done, on Laythe swimming. On Vall two landings were done, and on Pol and Bop the lander bounced around. This mission used a combination of a gravity assist off Tylo and a retro-burn to capture at Jool, and upon return to Kerbin parachutes were attached to the crew section using a klaw. A fun mission with great editing. - @king of nowhere ISRU Mission thread here. Collected 105136 science. This mission was insane from its conception, with the goal to collect every single bit of science from the Jool system as possible. While this goal was not ultimately accomplished, the mission is still one of the greatest Jool 5 submissions I have ever seen. To collect science on each world, a durable lander known as the Dancing Porcupine was deployed and driven on all moons but Laythe. For Laythe, a spaceplane called Absolutely NOT Albatross was used to collect science from each biome. In fact, Absolutely NOT Albatross did even more than just Laythe. Using a multi-stage attachment, Absolutely NOT Albatross visited the lower atmosphere of Jool and returned to tell the tale. The craft's brave pilot even took an EVA report while in flight before ascending. The main ship dubbed the Flying Christmas Tree, and was capable of refueling on low gravity worlds. Upon returning to Kerbin, a craft launched to return the brave Kerbonauts to their home-world. Having visited every biome on every moon, it is no surprise that this mission amassed more science than any other Jool 5 mission before it. I highly recommend viewing this mission's main thread. Amazing job king of nowhere! Mission thread here. Collected 11395 science from the Jool System. The sheer amount of effort put into this mission cannot be overstated. King of Nowhere started this mission as a nanocristalline diamond caveman mission, which in short meant no contracts, no facility upgrades, no quicksaving, on career mode, while starting the save with severe limitations. While the mission ended up needing quick-loading, it still is eye popping to see just how much work went into it. Each launch (in the VAB) was limited to 18 tons maximum, so a work around was used by having docking ports around the base of the rocket, to which separate boosters would be docked using a runway-launched rover. This meant that many launches required multiple launches of booster attachment vessels before the rocket itself could attempt to leave the pad. After over 100 launches, the Navis Sideralis Neanderthalensis and all its cargo were ready, and the ship departed for Jool, leaving a most amusing pattern of drop tanks in its wake. Upon reaching Jool, disaster struck when the Tylo lander suffered an anomaly, and quicksaves were needed to complete the Jool 5. While at Jool, science modules were discarded after use because a lack of KSC upgrades prevented their resetting, and every aspect of the mission, from flying between moons to the landings themselves, were executed with meticulous testing and prior calculation. I cannot possibly explain everything this mission did in this little blurb, so I highly encourage anyone who wants to see some of the best Kerbal engineering I've ever seen to check out the linked mission thread above. ISRU Mission thread here. Collected 142744 science (Current Record!) from the Jool system. This mission is perhaps the greatest Jool 5 missions to ever fly. A worthy successor to @king of nowhere's previous submissions, this mission collected practically every single piece of science that the Jool system has to offer, with only a few dozen science bits unobtained. In addition, the mission visited every single anomaly in the Jool system, performed circumnavigations of every moon, and flew a two-crew craft into Jool's upper atmosphere to collect science, and deployed an aircraft carrier to Laythe. The mission's thread linked above follows the journey of the Flying Christmas Tree 2, a massive mothership capable of landing and refueling itself, Leaping Mantis, a rover designed for climbing steep grades on alien worlds, Tamarromobile, a larger rover for Tylo, Phoenix, the spaceplane for Jool, Absolutely Not An Albatross, an SSTO for Laythe, and Garibarge, the aircraft carrier for Laythe so that Kerbals could disembark from Not Albatross and collected surface samples from Laythe's ocean biomes. The mission began with Flying Christmas Tree 2 being equipped with the landers, planes, and aircraft carrier. Use this link here to see the majesty of Flying Christmas Tree 2 in all its glory -> (https://youtu.be/h61wplb0DRw?si=HlNYwxnYPkPaem2k). From there, it flew to Minmus to land and refuel, and then departed for Jool. The following efforts to circumnavigate all 5 moons and locating the anomalies require an entire thread of its own, requiring one to view and read the entirety of the mission thread linked above. Out of all the Jool 5 missions I have ever reviewed, none have exhibited such effort or gone to the extent shown here. This is not one of many Jool 5 missions, this is the Jool 5. - @OJT ISRU Mission thread here. Collected 26871.3 science from the Jool System. This mission thread contains some of the most eye-catching, visually stunning KSP screenshots I have ever seen in a Jool 5 submission. The mission itself was tested and proofed in sandbox, and consisted of a long, skinny mothership, a spaceplane, and an ISRU lander for Tylo. With the lander and plane hanging from docking points on the main ship, the craft boosted to Jool and used a Tylo flyby to capture. Visiting Vall first, the lander took around 100 days to refuel. The ship then flew to Pol where the relatively tiny lander (in relation to the mothership) flew to Pol's surface and back numerous times to refuel the main ship before it could head to Bop. At Bop a kraken was discovered, and on Tylo the crew found it refreshingly eventless. The last destination was Laythe, where the plane and lander were left in orbit so the main ship could return to Kerbin. A return craft returned the crew and science, and crew XP was had by all. - @Robin Patenall Mission thread here. Collected 61174.6 science from the Jool System. This mission began with the construction of the Emerald Star, a large and reconfigurable interplanetary vessel that required 17 launches to complete. Once built, the Emerald Star used Eve and Kerbin gravity assists to efficiently sling itself to Jool and started with Tylo. Using one of the Emerald Star's 3 drive cores to send itself down to a lower Tylo orbit, the lander successfully brought the crew to and from the Tylic surface. When the mission reached Vall, a magical anomaly was discovered, one which would prove to be only one of many odd discoveries made on Jool's moons. An SSTO found one on Laythe as well, during one of its three total landings. A monolith was found on Pol, and a deceased kraken on Bop, one which caused a crew member to lament their inability to bury it. Once the landings had been complete, the remains of the Emerald Star returned home, where it was parked in Kerbin orbit awaiting future assignment. - @problemecium Mission thread here. Collected 8755.7 science from the Jool System. This mission thread covers the finally completed tale of the Aletheia, a massive, nearly 1.3 kiloton mothership. With numerous cargo bays, it brought landers, an SSTO, a deployable space station, numerous pieces of scientific equipment, and two ARKS to return the crew to Kerbin if needed. Upon construction, Aletheia and its seven crew members proceeded to Jool, using 46% of its total fuel. The transfer section was left behind in Laythe orbit while the rest of Aletheia continued on. After Laythe came Vall, where one of the ARKS was used to refuel the Tylo lander to enable it to tackle Vall (the ARK was then joined to the deployable station and left behind). The lander then tackled Tylo, and was left behind for future use. Bop saw the discovery of a hopefully deceased Kraken, and Pol marked landing number 5. This romp unfortunately depleted Aletheia of the fuel sufficient to return to Kerbin, so the second ARK spacecraft brought the crew home safely, using a Mun assist to tweak its final trajectory. This is one of the more aesthetically pleasing Jool 5 missions, and done in career mode in a very well typed out and necromanced thread, so if you are a fan of large stylish motherships, I would recommend giving this thread a view. Gatecrashers / Honorary Mentions - @JacobJHC Grand Tour, video here. Giant single launch craft, also visited every planet and moon from the OPM planet pack. Very big. Gatecrasher because crew hasn't landed yet. - @Fraus Mission here. There's nothing that can be said about this, other than that this mission definitely had more thought put into it than any other Jool 5 I've seen. - @cqIpb Mission here. This mission was flown on an Xbox, and pushed the console to its framerate limits! cqIpl was inspired to do a Jool 5 mission after finding this thread, and despite not being able to land on Laythe due to lander instability, still had a lot of fun finishing the rest of the mission, and took a few great screenshots along the way! As of writing this, cqIpb is still new to the KSP Forums. Welcome, we're glad you're here! - @Alpaca Z, using a craft built by @Lt_Duckweed (with permission) Grand Tour, ISRU . Video here. Using a rather simply built SSTA, this mission was a simple case of flying around the entire solar system and refueling everywhere. This craft utilized air-fans, ions, vectors, and nerv engines, allowing it to be not only capable of high efficiency maneuvers, but also those requiring high TWRs. A highlight of this mission was the strategy to use EVA construction to rebuild the back of the plane to enable it to land vertically on Tylo's surface. Why bring landing legs when you have wings that could do the job just as well? This mission's video submission is also of a high quality, so I recommend giving it a view. In all, the crew of three finished their grand tour in only 15 years and 117 days! Efficient and speedy Moved to Honorary Mentions due to the fact that the crew could not exit onto Tylo's surface.

This challenge was continued with permission from the previous thread manager @sdj64 LINK to the old Jool-5 thread There are over forty-five pages of entries and discussion, so look and see what made it and what didn't LINK to the older Jool-5 thread. There are hundreds of pages of entries and discussion, so look at it to see what worked and what didn't! CHALLENGE RULES Given the scale of this challenge, everyone who completes the mission successfully gets a spot in the hall of fame. 1. No cheating, including the stock debug menu cheats, HyperEdit, kraken drives, or file editing. HyperEdit is allowed for testing but get rid of that H when you fly the real mission! 2. No part-clipping of functional parts (fuel tanks, batteries, crew pods, engines, science parts, SAS) into each other. It is okay to clip structural and non-functional parts, wings, and heat shields. 3. Any number of launches are allowed to assemble the ship in low Kerbin orbit (preferably below 100km, not a hard ceiling though, but do try to stay around or below 100km at most). All launches must be flown! 4. There's funding for one main ship only so all the crew, lander(s) and other stuff has to go to Jool as one big ship. Once the ship leaves LKO, it cannot obtain more parts or fuel unless it mines and refines the fuel itself. The ship can separate once in Jool's SOI. 5. Kerbals must be in a pod or cabin (no seats) for the interplanetary journey. Seats are okay for landing and flying within the Jool system. 6. One refueling mission is allowed in the Jool system if you run out of fuel, unless your ship uses ISRU. The refueling mission can only transfer resources, not parts, to your Jool 5 craft. This mission must actually be flown! 7. On all of the landings, the Kerbal must be able to get out and walk (or swim!) around on the surface. Make sure your ladders work! 8. Use Normal difficulty or harder, except, any ComNet settings are allowed including turning it off completely. 9. All the Kerbals have to arrive back to Kerbin surface at the end of the mission, happy and alive. You are allowed to optionally send up a craft to return them from LKO. 10. Mods / DLC: STOCK: only mods which do not add parts and do not change physics are allowed. This includes any informational, planning, visual, autopilot, or automatic functions. DLC: Any and all DLC made for Kerbal Space Program are allowed. MODDED: Use of most parts mods and certain game mechanics mods are allowed. You NO LONGER HAVE TO ASK if your favorite part pack is allowed! Some parts mods are prohibited. Please see below. Specific Mods: ENTRY SUBMISSION RULES 11. Submit your challenge as an imgur album, with good captions and descriptions, as a video or series of videos, or as a thread in Mission Reports. 12. Pictures or it didn't happen! Please keep the resources tab open, as well as show the informative windows from Mechjeb or KER if you use them. Take a picture of every important moment, including transfers, dockings, landings, stagings, and refuelings. For Jeb's Level, also take pictures of the science screen when you recover your craft. Alternatively, video submissions are a great way to show everyone your mission as well. These will help future participants to see exactly how you accomplished each part! CHALLENGE LEVELS 1ST LEVEL: one Kerbonaut lands on all the moons and come back safely. Low mass and low cost and low parts sub-challenges: with stock parts and physics, how low can you go and still accomplish the mission? NOTE: Low cost submissions may not utilize ISRU, or a negative cost would be possible. (Thanks @jinnantonix!) 2ND LEVEL: two or more Kerbonauts land together on all the moons together and come back safely. 3RD LEVEL: There's not enough time left for training one crew member to be an expert on all of the moons, so five Kerbonauts must go to the mission, with at least one unique Kerbonaut landing on each moon. JEBEDIAH'S LEVEL: collect as much Science as possible! Your score is the number of science points from the Jool system only, returned to Kerbin (not transmitted). Only stock experiments count for this! To score, take pictures of the science screen(s) when you recover the data. Otherwise, the rules are the same as 3rd Level. GATECRASHER / HONORARY MENTIONS: Missions completed the mission in spirit but didn't meet every requirement. ISRU: Use of ISRU will get a note ISRU on the entry description in the hall of fame. This includes stock ore harvesting and converting as well as mods such as Kethane and Karbonite. ISRU is allowed for any level of completion. GRAND TOUR: Not officially part of the challenge, but landing on all planets and moons in the Kerbol system in one mission will earn a GRAND TOUR note and the everlasting praise of all of Kerbal kind. Rule 4 is waived, but any Kerbals on the mission cannot return to Kerbin in between any landings and you still must follow the other rules. Additional optional information to help others see how the mission was accomplished: - Which game versions did you use? - What mods did you use, if any? - How many Kerbals are on the mission? - How many launches were needed to start your mission from Kerbin? - How much did your mission cost? - Did you needed a refueling mission? - Did you bring additional stuff like satellites, rovers, etc? - Share the delta-V information too, if you tracked it! ------------------------------------------------------------------------------------------------------------------------------ Well, now this big announcement is in the Kerbal News, all the public is excited about this mission and even the Government is watching! Now it's up to you, to the engineers and to the bravest and craziest Kerbonauts of all time! Completion Badge: Anyone who has finished the challenge can add this badge to their signature. The Low Mass Feather badge is available for entries in the low mass sub challenge. Hall of Fame 1st Level- - @Laie Video here. Used a smaller-than-you'd-expect rocket with a dedicated Tylo lander and a spaceplane shell that encloses the Vall-Bop-Pol lander to make the Laythe lander. A very well done mission with a great video. - @Stratzenblitz75 Video here. Used a completely reusable mission involving a tiny mothership which orbited Tylo and tiny landers that explored the system. I should also point out that no nuclear engines or ions were used in the mission. Truly impressive. - @Ultimate Steve Videos here and here. Used a single launch in career mode sending Val to many places in the system including Vall. Very impressive how quickly the mission was thrown together and carried out. - @IncongruousGoat Album here. A simple, single launch Jool 5 mission that only uses 42 parts! Very well optimized and well done. Good job! - @chargan ISRU Gif here. Used an ISRU shuttle and hopped from Kerbin, to the Mün, to the Joolian moons, to Duna, and finished it off with a glorious vertical landing at the KSC. Excellent job! - @GRS Album here. Used a massive, creatively named mothersheep that carried landers for Laythe and Tylo, landing on Vall and Bop (AND DRES!) by itself. As an added bonus, the lonely Dres was even visited, that doesn't happen very often. Amazing job! - @Challyss Album here. Used a brute force 5 meter launch booster with two 5 meter side boosters. Once in LKO used a vector-power stage to boost to an elliptical orbit, then used a rhino powered mothership to go to Jool, where it completed the mission. - @5thHorseman Videos here. Used a single launch to send three Kerbals to the Jool system, where the ship parked in an elliptical Tylo orbit. From there a tug took the landers to their respective moons where they *wait for it* landed. The ship then fired all three Kerbals home safely. An amazing mission and equally amazing videos. - @Xurkitree Grand Tour Thread here. A surprisingly small mission that not only landed on all the Jool moons, but also every other planet and moon in the system. The mission sent a craft out to Eeloo, which landed and returned to Jool before heading home. Once in orbit Derton was picked up by a recovery rocket and landed safely back on Kerbin. Outstanding. ISRU Video here. I don't even know where to start, Xurkitree didn't just do a Jool 5 in this mission, they did it twice. A large SSTO ISRU craft launched and refueled on Minmus before gravity assisting its way to Jool where it completed the landings and then returned to Kerbin, WHERE IT RELAUNCHED and then detached a small non-ISRU craft which carried out the landings again. A fun note was when the Laythe lander landed by computer control while the Kerbal parachuted down. Great job on your fourth Jool 5 submission! - @dvader Album here. A single launch using only chemical engines. Used several gravity assists to make the trip to Jool cheaper in terms of delta-v. Used a small but capable plane for Laythe, and a donut lander for the other moons (with extra fuel for Tylo and Vall.) Overall a very optimized mission, complete with a near KSC landing. - @fulgur Album here. A very small and well optimized mission with a smaller-than-you'd-expect mothership. Ions were used to scoot Jeb and Vall about the system to the various moons, and then left as the small mothership made its way home, getting into Kerbin orbit with only forty m/s of delta-v remaining. (Talk about close margins!) The crew were returned safely by an Aether SSTO. - @Pro100kerbonaut ISRU Mission report here. Used an SSTO spaceplane to go to Minmus to refuel, then flew off to Jool. This mission is the most impressive in how it handled the Tylo landing. Not only was the landing done using the SSTO, but it came directly from Vall without refueling at Bop or Pol. The landings were all completed flawlessly, but was destroyed in a crash landing back on Kerbin. The pilot survived though, and any landing you can walk away from... - @dnbattley Album here. A direct ascent mission to all five moons, starting with Pol and Bop, then Vall, Tylo, and finally Laythe. The tensions on this mission were very high, as Jeb began his Tylo descent on a NERVA powered craft with a TWR of .9, managing to get it above 1 just in time to pull off the landing. From there Jeb flew to Laythe where he somehow missed the ocean (this might be a KSP first) and used the craft's jets to push it into the water for an ocean launch. After struggling back into orbit, Jeb flew by Tylo back to Kerbin, using a Duna aerogravity assist to get the right trajectory (ARE YOU SERIOUS?) Upon returning to Kerbin he was able to sneak in a Minmus landing. This mission is without a doubt one of the more Kerbal ones submitted, complete with Jeb gliding the final stage down to Kerbin with his EVA chute. - @EveMaster Grand Tour, ISRU Thread here. Additional album here. EveMaster managed to complete the Jool 5 challenge with an ISRU craft, utilizing the power of two mammoth engines and a detachable spaceplane. Also went the extra few million miles and completed a grand tour! Both Bob and Jeb were on this mission, however Bill stayed behind on Eve, so only Jeb is being considered for this entry. Regardless, an excellently executed mission. - @ManEatingApe, @Jacke, @dvader, @Muetdhiver, @Rakaydos, and @Pds314 Mission thread here. What these users have completed is the first community Jool 5 mission for this specific thread, possibly the first ever. Furthermore, this mission was done in a 'caveman' style approach, meaning no maneuver nodes, tier one buildings, and launch mass restrictions. These restraints meant the main ship was built over multiple launches. The landings were carried out by a plane and three identical landers, which carried Jeb to, around, and back to Kerbin from the Jool system with excruciating precision. I highly suggest checking out this mission's thread, it's one of a kind! - @Space Nerd Album here. Using a long nuclear mothership, Jeb and Malvis conquered the Jool system in a surprisingly easy manner. An off-center Bop/Pol lander was docked onto the side of the mothership, leading to one of the more interesting mothership designs. Jeb took Laythe, Tylo, and Vall, and Malvis handled Bop and Pol. Once all the landings were done, they flew back to Kerbin and used a 10 meter heat shield to slow down and splashed into the ocean. - @ralanboyle Video here. Using a single brute force launch, a main station of sorts was put into Jool orbit,. From there a Laythe-plane was released, and upon returning from Laythe, a lander/fuel tank combo (and an extra part for Tylo) took on Tylo, then Vall, then Bop, then Pol. They forgot to put a flag on Pol, but who cares. Also, the lander was able to return to Kerbin all by itself. Quite the capable craft I'd say. The mission is edited into a very nice video, and I suggest giving it a watch if you've got the time. - @Carbonjvd Album here. Using the incredibly stylish IPV Excelsior spacecraft, Tridous Kerman flew to Minmus to refuel, where she picked up two more crew members in Minmus orbit. From there they flew to Jool, where they refueled at Bop. After the tanks were full, they hopped to Pol, then Tylo, then Bop again, then Vall. From Vall the crew hopped back to Bop for more refueling, then flew to Laythe. After converting stored ore into liquid fuel, the crew touched down on an island, then (you guessed it) flew back to Bop! (for more fuel) From this final Bop landing, the Excelsior returned to Minmus where it all began, then safely touched down on Kerbin. A stylish landing for a stylish craft. - @camacju Grand Tour. Album here. This mission is impressive as it not only visited the five moons of Jool, but also every other landable surface in the Kerbol System. The Jool portion of this mission was completed after the mothership completed the Eve portion, then used gravity assists to get to Jool. A Tylo assist put the ship on course to aerobrake at Laythe, and after landing on Laythe the lander was then reused for Tylo. The other moons were completed using a smaller lander, and the brave Kerbonaut landed back at Kerbin after quite an exciting trip. Video here. A very well edited video of a Jool 5 mission which used only liquid fuel! Launching from the runway as a spaceplane, the craft flew up before staging its rapier engines and continuing to orbit on nerva-power. The Laythe landing was done using a smaller spaceplane, and the rest of the landings were done using a very impressive lander which used only 1 nerv engine to land on all the other moons, including Tylo! The lander also served as a trip home and as a heat shield so that the brave kerbonaut could parachute to safety. This mission is beautifully summed up in the video link, and I highly suggest checking it out. A truly unique mission! Video here. Another liquid fuel only mission! This one utilized multiple relaunches of the same spaceplane to put multiple fuel tankers in orbit. From there, the craft departed for Jool after some gravity assists and once again demonstrated the unusual, difficult, and impressive use of a nerv-powered Tylo lander. The video this mission was edited into is nice and tidy as well, and I suggest watching so you can see all the work that went into it. Video here. And yet another Jool 5 mission, but this time with only one engine! A cargo spaceplane with a single rapier made multiple launches to place several fuel tankers into orbit before flying a gravity-assist-utilizing course to Jool. Once in Jool space, the Laythe landing was conducted first, and then the plane ditched its outer shell so that just the rapier engine and a few fuel tanks remained. The craft then docked to a fuel module in orbit and flew to Vall, landed, then went to Tylo where a dedicated fuel drop-tank was used with what I'll dub "backflip staging". From there the Pol and Bop landings were done, with fuel to spare. After a fiery return to Kerbin, the brave Kerbonaut, Wildard, paraglided safely into the ocean. I recommend giving this video a watch, because it's short, to the point, and an amazing display of Kerbal engineering. Grand Tour. Video here. This mission is truly a record breaker, as not only was it a Jool 5, but it is the lowest mass Grand Tour without ISRU record holder, with a take off mass of 14.447 tons, less than a Mammoth engine! To focus on the Jool 5 portion of the mission, a spaceplane made a bouncy, thrash-flippy landing, then a tiny tiny lander was used to tackle Tylo. Pol and Bop were handled by a small ion lander, and Vall was handled by a lander so small it looks like a pancake. You should definitely give this mission's video a watch, as words cannot truly describe just how insanely optimized this mission was. - @Goufalite Video here. This mission began with the assembly of a main mothership in LKO. Once complete, the ship cruised to Jool where it used gravity assists to achieve orbit. From there, the spaceplane was deployed to Laythe, but missed its target island. Never fear! The spaceplane had such high performance it was able to fly to a nearby island. Once back with the mothership, the SSTO was drained and detatched, and a capsule on its nose was undocked and docked to the Tylo lander. The Tylo lander used 2 aerospike engines to blow its way to the surface, and the final stage of the lander redocked to the mothership to be reused as the lander for Vall, Bop, and Pol. After visiting Vall and Pol, the lander flew by itself (and out of connectivity range) to Bop, where it landed and returned to Pol all on its own (Goufalite found this method was more fuel efficient). After returning to the mothership at Pol, a Tylo gravity assist sent the crew home, and both safely landed only 50 kilometers from the KSC. This mission made me nostalgic for my first Jool 5 mission, which in turn makes this mission special to me. Nice job, @Goufalite. - @king of nowhere Grand Tour. Mission thread here. This mission was done using Kerbalism, and an absolute UNIT of a mothership. Appropriately named the DREAM BIG, this ship conducted the Jool 5 challenge with dozens of farms, radiation shields, and drop ships to keep itself self-sufficient. Fighting food limitations, mod issues, solar storms, insanity and radiation damage, the crew of DREAM BIG flew throughout the entire Kerbol system planting flags on every world. The mission thread is an entertaining read, and has a video tour of the DREAM BIG spacecraft, which I highly recommend you check it out. I congratulate @king of nowhere on completing the mission, and for not losing their sanity in the process! Mission thread here. This mission was done with tremendous build constraints, and done entirely in a no-contract career mode save. Each launch was limited to 20-25 tons, meaning it took dozens of flights to finish the main ship, the Marco Polonium. The ship used many cost and weigh saving methods, including using the Laythe lander as a stage on Tylo, and by using claws instead of docking ports in some cases. The mission also visited Duna, Ike, Eeloo, Dres, and Eve (orbit) as well. This mission is one of the most entertaining ones I've reviewed (along with one of the most optimized) and I highly recommend giving it a read. Mission thread here. This mission was much like @king of nowhere's previous two in the sense that it involved Kerbalism and self-imposed building constraints. The result was a Jool 5 mission designed and flown to be as realistic as possible, and done with a maximum LKO mass of 140 tons. Bill and Bob took the Economic Downturn and its support craft to Jool and visited Tylo first, using the Seated Man lander, then made way for Laythe to deploy the Sole spaceplane, each accompanied by the space tug Right Answer. Sole's upper stage was reused as a Vall lander, while Seated Man's upper stage was used to land on Bop and Pol. For the inner three moons, great care was taken to limit the radiation damage incurred on the crew, with Bill being irradiated all the way to 95% upon his return to Economic Downturn. The return trajectory had to be tweaked a few times to prevent the capsule overheating, but Bill and Bob ultimately prevailed, and returned to Kerbin with nearly 500kg of samples. This mission is one of the few anxiety inducing submissions due to the challenges imposed by Jool's radiation belt. If you are a fan of gripping mission threads, I suggest giving this one a read. - @Lt_Duckweed Video here. This Jool 5 mission is notable for three reasons. Firstly, it is fully recoverable. Secondly, it only uses two engines, being the nerva and rapier. And thirdly, it was edited into a masterpiece of a video. This mission began with a launch just west of the KSC, and made a direct transfer to Jool. Upon Jool arrival, the elegently designed craft deployed a nerva-propelled lander, which performed the Tylo landing. After refueling at the main ship, the lander then visited Vall, Bop, and Pol with refueling trips to the main ship in between. The lander then returned to the main craft, which transfered to Laythe, completing the final landing. The craft then returned to Kerbin and came to a stop on the KSC runway, returning with it every part it launched with. I must repeat the high quality video the mission is edited into, and strongly suggest giving it a watch. - @bwest31415 Album here. This mission began with the launch of a long thin rocket which was followed by a normal transfer to Jool. Upon arrival to Jool however, inflatable heat shields were used to induce a Joolian aerobrake, a maneuver I've scarcely seen used since the addition of reentry heating to the game. The first landing to be done was Laythe, and the final stage of the lander was used to land on Vall and Tylo. The lander then left the main ship behind and traveled to Pol, then Bop, then back to Kerbin all without refueling. Jeb landed safely back on Kerbin after a toasty aerocapture, and exited the pod to take in a nice mountain view. - @18Watt ISRU, Thread here. This mission was done as both a Jool 5 and a Kerpollo submission. The mission began with a brute force launch and direct transfer to Jool. The mothership used wolfhound engines, which was good for TWR but slow when the ship was fully fueled. The ship flew first to Tylo, and after landing, the Tylo ascent stage would be reused for later landings. Next, the ship went to Bop to refuel, then to Laythe, where a staged spaceplane returned the brave Kerbonaut to the mothership. Next Val went to Vall, then the ship went to Pol and landed, before returning the crew to Kebrin, who parachuted to the surface of one of Kerbin's icecaps. - @OJT ISRU, Thread here. This mission was fully reusable* (apart from deployed fairings but we couldn't decide if that counted or not) and landed every component of the main ship back on Kerbin upon finishing the Jool system's exploration. The mission began with three launches, one for the mothership, one for the lander, and one for the SSTO spaceplane. Due to unfortunate moon placements, no gravity-assisted captures were possible and a retroburn was conducted. From there, a surprise Laythe aerocapture was conducted, saving much needed fuel. After the Laythe landing, the main ship flew to Vall, left the plane in orbit, and then landed with the lander beneath it and refueled on the surface. Next up was a Tylo landing with razor thin fuel margins, followed by Pol and Bop. It is worth noting that this mission did not repeat OJT's previous Jool 5 mission's Pol refueling process, in which the lander did numerous trips to the surface to bring tiny bits of fuel up to the main ship. With the landings complete and plenty of fuel to spare, the ship flew back to Kerbin where it landed piece by piece, with the lander being launched an SSTO parachute module. An excellent mission, and no doubt a fine achievement. - @kspfreak Video here. This mission not only visited the moons of Jool, Bop's Kraken, and in a rather small vehicle, but also visited every other moon in the entire Kerbol System! This mission's video is a fun watch, and ends with a fun paraglide back to the KSC. A mini grand tour of sorts, and very well done. - @JeDoesStuff ISRU, Video here. An SSTO submission! Coming in with a mass at just under 30 tons, JeDoesStuff showed off an incredibly refined ISRU SSTO by flaunting it around the Jool System. Included on the spaceplane are subtle but clever features to aid in launching horizontally, such as Vernier thrusters on the nose to raise attitude during takeoff, as well as a large landing gear that is only deployed to angle the craft. I haven't seen the latter of those additions on an SSTO before, so I applaud the ingenuity! The video this submission is contained within is also very well edited, resulting in a brief, yet concise viewing experience. If you're looking for a fun video to watch, or to see a razor-thin-margin Tylo landing, then this submission is for you. Low Mass - @EvermoreAlpaca Video here. Mass of 6.2 tons. Spaceplane launch, gravity assists off Kerbin and Eve to reach Jool. Landed on Laythe with the same rapier used in the launch stage, returned to orbit with an incredible TWR, scooted over to Tylo where the most bare-bones Tylo lander I've ever seen was used to land on and take off from Tylo (saved fuel by having Bill push it to the top of the mountain), flew over to Vall where the landing was done using staged batteries and a single ion engine. The Vall lander (which was also part of the Laythe lander) completed the last two landings on Bop and Pol and returned to Kerbin using many more gravity assists before preforming an aerobraking, with Bill parachuting to the space center and landing atop the RnD. - @Alpaca Z Video here. Mass of 5.8 tons. Vertical launch using a whiplash ramjet engine, which was staged prior to orbital insertion. Resonant orbits with Kerbin and Mun assists were used to set up a KEKKJ gravity assiste route to save fuel. Spider engines were used in a two-stage Laythe lander design to save weight, and EVA construction was used to rebuild craft to negate the need for decouplers or rebuild the craft (or get away with only bringing one chair). Landings were otherwise routine apart from an incident on Tylo where the lander fell on its side, requiring an intuitive solution to rebuild the craft in such a way it could use redundant engines as support pillars. The video is very well narrated and goes into much more detail regarding the craft's design and flight plan, I highly recommend watching it to get the full picture of this mission. - @camacju Video here. Mass of 5.2 tons (Current Record!). This mission not only shatters the previous record, but does so with an impeccably made video. Launch mass was saved in numerous ways, one of which involved using tiny flags in place of landing gear for the horizontal KSC Runway takeoff. EVA construction was used to reassemble the craft(s) into what was needed at any given point during the mission. The vessels flown and techniques used are difficult to describe, so I highly encourage a watch of this mission to see some of the best of Kerbal engineering. - @camacju and @Ultimate Steve Grand Tour, Video here. Mass of 7.6 tons. This is a meticulously crafted and borderline perfectly executed low mass mission. This was not only a Jool 5, but also an entire grand tour weighing not even 8 tons! The video's excellent editing allows it to speak for itself, and I highly recommend you watch this mission to see perhaps the greatest low mass mission in the history of KSP. Low Cost - @jinnantonix Video here. 34,663 funds. The thread's first low cost submission! Using a low cost launch vehicle and a K-E-K-K-J flyby route, the mission put Val and a fuel-tanker station in elliptical Laythe orbit. From there one lander tackled Laythe, and another tackled the other four moons, with an extra few stages for Tylo. It is worth mentioning that this mission used no electrical charge and relied entirely on engine gimbal and some RCS to steer. On the way back, a double Eve flyby helped slow down, so an aerocapture could be done at Kerbin, where Vall proceeded to parachute onto the VAB. - @camacju Mission here. 24,070 funds. This mission used a SRB powered launch stage and a terrier powered transfer vehicle to get the landers to Jool (after numerous gravity assists). A dedicated Laythe lander tackled the ocean-world, while a multi-stage Tylo lander tackled the rest of the moons, and returned the brave Kerbonaut Wildard Kerman to Kerbin. Before heading back however, the new space-construction method was utilized to steal a solar panel from the transfer stage, marking the first time this creative form of staging has been used. Mission here. 17,635 funds (Current Record!). This mission is a more stripped down version of @camacju's previous low cost mission. This mission featured a visit to Laythe's ocean floor, and utilized eva construction to manually remove empty fuel tanks from the mission. Additionally, eva fuel tanks were used to refill the brave kerbonaught's jetpack to enable fuel savings by extended jetpack use. Low Parts - @bayesian_acolyte ISRU, Album here. A small, single stage craft comprising of 31 parts. Bayesian_acolyte said there could have been some part count improvements, but even without it the mission still did so much with so little. This mission shows just how far ISRU can be stretched, especially with that Tylo landing. - @Majk Thread here. A simplistic Jool 5 mission consisting of only 30 parts . The mission began using a very basic launch stage, and flew to Jool using a long nuclear ship. Lander reuse enabled part count savings, and usage of the nuclear ship as an ablative heat-shield helped return Val to Kerbin's surface in one piece. - @Majk Video here. Easily the most simple Jool 5 mission completed to date, accomplished using only 9 parts (Current Record!). This mission started with the 9th part, an RTG, stowed inside the command pod before installing it in orbit. It is also worth recognizing that a clever method of timewarping in the tracking station enabled refueling to take place while utilizing only a single RTG. The submission takes the form of a short, concise, and wel narrated video, and I highly encourage giving it a watch. 2nd Level - @jinnantonix ISRU, Album here. Used a big launch with a self-refueling vector-powered lander that made multiple Laythe landings and mined ore from every moon. Two kerbals were landed on each moon and the lander was recovered at KSC. - @Kerbolitto ISRU, Album here. Excellent mission done using two space shuttles capable of refueling on moons. Absolutely amazing job. In all things I ever thought I would see happen in KSP, a space shuttle landing on Tylo was not one of them. - @Marschig ISRU, Videos here. Not one, not two, but three ISRU planes flew to Jool and to all five moons on both the 3rd and 2nd levels. The SSTOs also visited Duna and Minmus in their missions before landing back at the KSC. Truly exceptional. This is the first time I've seen three Jool 5s all submitted at one time! - @PhoenixRise86 Album here. Used a mothership for the first part of the mission, then resorted to ions to get to Ike and Minmus, then safely back home. Also, this is the first 2nd level mission to not use ISRU. - @GRS: Album here. The highly anticipated Sheep v2 did not disappoint, and went above and beyond by visiting not just Jool's moons but also Kerbin's and Dres. Used massive nuclear boosters to get around the Jool system and the Tythe lander to get two Kerbals on every moon and Dres, before using the Sheep v2 to land the entire crew on Minmus and Mun. Spectacular! - @Xurkitree ISRU Video here. This modded mission utilized ISRU, a nuclear mothership, and eight aerospikes to land on all five of Jool's moons with Cerdrin and Lodous Kerman. Returned the lander and mothership to LKO where a separate rocket retrieved the crew. I highly encourage watching the video submitted, it is excellently edited and the music supports the awe of the mission. - @QF9E Thread here. This mission used a blunt-force approach by lifting off on a powerful launch stage, and made quick work of Jool's moons. The moons were all visited by one lander, which dropped various attachments that helped it land on some of the bigger moons. At the end of the mission, the three brave kerbonauts safely touched down in the ocean, and a BFR style spacecraft recovered the remains of the lander in Kerbin orbit for historical preservation. Truly an impressive mission indeed! - @Mars-Bound Hokie ISRU Mission here. Using the Anubis II SSTO, Tancan, Fernal, and Kenby Kerman flew to Minmus to refuel, then blasted off for Jool. After touching down on Laythe to refuel, the crew went for Bop, then to Tylo. After landing with no liquid fuel to spare, the Anubis II was refueled, then launched for Pol. After a risky auto-piloted landing, the ship refuel before bounding to Vall, where the crew had a group picture. Heading back to Kerbin, a mix of brute force and aero-braking was used to get the trajectory needed to get back to the KSC, and then the crew refused to ditch the plane and pulled off the legendary runway landing. - @king of nowhere Mission here. "And so I completed the Jool 5 in day 383, 1 hour and 9 minutes of a new career" are the words typed by @king of nowhere at the end of the mission thread, and fundamentally capture the astronomical accomplishment documented within it. In a career save speedrun, it was decided to focus on a Jool 5, and the mission was optimized for time rather than mass or cost. The amounts of delta-v put into each maneuver to achieve bullet-like trajectories around the Kerbolar and Jool systems is simply jaw dropping. Over the course of the flight, the La coscienza di xenon and its landers managed to plant flags on all 5 moons within a 12 day window, which I don't believe has ever been done before. If you wish to see the chronicles of a one-of-a-kind, record setting Jool 5 mission, the flight of the La coscienza di xenon is the mission thread for you. Grand Tour Mission here. @king of nowhere's second Kerbalism Grand Tour, but with radiation shielding 3 times less effective, bugs, life support issues, frantic crew members smashing fuel cells and dumping food overboard, and so much more! This mission chronicles the Nail Bolt on its tour around the solar system, finding monoliths on every world and making it back in roughly two decades. This mission thread covers the begins, rebeginnings, redesigns, quick fixes, and compromises that took place during the Bolt's journey not just to Jool's 5 moons, but to every other surface as well. This is one of the most thorough submissions the challenge has seen, and is a great resource for those considering Kerbalism entries of their own. - @Lyra Mission here. A single launch mission! Using a spaceplane for Laythe, a notably slim Tylo lander (with a reusable upper stage for Vall), and an ion lander for Bop and Pol, this mission was a pleasant, self contained romp around the Jool System. One unique aspect of this mission I've seldom seen elsewhere was the use of claws on the nuclear mothership's outer hull. This allowed the landers to not need docking ports and attach to the hull like barnacles. A very clever, mass saving decision for the landers for sure! 3rd Level - @iAMtheWALRUS Grand Tour, ISRU, Album here. Used SSTOs to launch the mission and used moon hopping to get around the Kerbol system. Very nicely done. Also, first 1.4 submission - @sturmhauke Album here. To put it in the words of the pilot them self; "A mostly reusable mission to all 5 of Jool's moons. Single launch SSTO carrier drone, with a separable mothership and 5 landers." Very well done and efficient mission. Used fuel cells to power ion crafts for Bop and Pol, sent a plane to Laythe, and conquered Tylo with a rocket lander. - @mystifeid Album here, ISRU. Used two launches to put a mothership and a universal lander into orbit. Then used left over launch stage to boost to Jool and then around the system until it ran out and was staged at Tylo. Bob landed on every moon, accompanied with a different Kerbal for every moon. Very nice mission, and even had the added bonus of a near KSC landing. - @PhoenixRise86 Album here. Used a single launch of pure rocketry, no jets, ions, or nukes used in the entire mission. This mission did the Jool 5 mission in style, with some of the most interesting landers I've ever seen, including an aerospike Laythe plane. - @Marschig ISRU, Videos here. Not one, not two, but three ISRU planes flew to Jool and to all five moons on both the 3rd and 2nd levels. The SSTOs also visited Duna and Minmus in their missions before landing back at the KSC. Truly exceptional. This is the first time I've seen three Jool 5s all submitted at one time! - @jinnantonix ISRU, Video here. Of all the Jool 5 missions I have seen in this thread so far, none treat their Kerbals better than Jinnantonix has. The craft was modular in design and split into several different arrangements for various landings, and came with a gravity spin for deep space transit. Very considerate, and very awesome. - @Grogs Album here. Two launches to build the main ship in orbit, one crew launch for realism. Used a giant transfer stage to get the landers to Jool. Chemical engines pushed the landers about the Jool system, with nine Kerbals in total being involved in the mission. Once the landings were completed the mothership returned to Kerbin where a fourth launch collected the Kerbals and returned them safely to Kerbin. - @Pipcard ISRU Thread here. A well executed, eight Kerbal mission with one of the longest ships I've ever seen in this game. Excellent mission that toured the Jool System in an engaging thread. Mission was assembled in multiple parts, flew to Jool, landed on the moons (being sure to refuel on Bop and Pol when needed), EVA jetpacked off Tylo, and the crew was returned to Kerbin by a separately flown space plane. - @Kerbolitto ISRU Mission here, here, and here. Kerbolitto's second submission! Using a space shuttle with several surface experiments, a crew of eight explored the system. The Tylo landing was done with perfect margins, landing with no fuel left! This craft may also hold the record for lowest TWR launch of Bop in history, and an outpost on Laythe with a mini-plane was even constructed. Bob chose to stay behind and man the base while the crew returned home. Excellent end to an excellent mission! - @Ksp Slingshooter Album here. Assembled the main ship using multiple launches, then flew to Jool, settling in an elliptical Jool orbit with some help from a few gravity assists. From there the landers detached and flew to their moons, one by one and completed their landings. Due to some unexpected occurrences at Laythe, the Vall lander swooped in and rescued the Kerbal, taking both back to the mothership. Without enough room in the command pods for everyone, two brave Kerbals rode back to Kerbin on ladders, detaching and re-rendezvousing during timewarp. A rescue craft was launched, and met the mothership just in time, with only three minutes to transfer the Kerbals before a fiery re-entry. Truly a Kerbal mission! - @RoninFrog ISRU Thread here. Using the gloriously huge HMS Sauron, Jeb and 16 friends took to Jool in this massive SSTA. First they stopped at the Mun, then flew to Pol, then Tylo, then Vall, Laythe, and finally Bop. On the way back to Kerbin, time and fuel and the positions of the planets made a Duna landing prove itself most useful, before heading back to the Mun, and finally, back to Kerbin. This 1 stage mission has some amazing screenshots in its thread, as well as most amusing comments for each picture. If you're wanting to learn more about an ISRU approach, I suggest giving this mission a peak. - @OutInSpace Video here. Using a total of eight launches, this mission's mothership was constructed methodically, complete with an enormous pair of transfer boosters. After heading to Jool directly, the mothership flew to Tylo, Vall, and Laythe by itself, and sent an ion craft to Bop and Pol instead. After numerous attempts, the Laythe plane was finally able to show what it could do, and the 5 crew returned to Kerbin orbit, where they were picked up by a landing craft. If you want to see the nitty-gritty maneuvers used during a Jool 5 mission, I suggest you check out this mission's video. Its editing and methodicalness make it an unintentional flight-tutorial for getting to Jool. - @Entropian ISRU Mission here. Using a 5 meter tank with 5 meter tanks strapped on the side and a large cluster of mastodon engines, the craft rocketed off the pad to Minmus, where it refueled and went off to Jool. Landing on Laythe proved to a close call, with ZERO delta-v remaining upon touchdown. From there the ship bounced to Vall, Tylo, Pol, and Bop, before making a rough splashdown on Kerbin. It is worth noting that the crew did forget to put a flag on Bop. However since every other mission criteria was met and the craft was landed on Bop it is still being counted. - @GRS Grand Tour. Mission here. This time with the Sheep v4 the Jool moons were visited again, along with 60 other destinations! Relying heavily on ion power, landing after landing was accomplished visiting worlds close to the sun, around Jool, and even outer dwarf planets. So many worlds were mentioned that the Jool 5 portion is only a tiny fragment of the overall mission. There is genuinely too much in that mission to describe here, so I highly suggest you check out the most expansive sheep yet's thread! - @s_gamer101. Mission here. This mission began with the launch of an enormous reusable launch system that placed the main ship in orbit. A trip to Jool ended with a fiery aerocapture above Laythe, where two of the crew members took a small spaceplane to the surface. After a tricky fuel situation in which drop tanks were accidentally kept as huge pieces of ballasts, the Tylo tug was used as an extra stage to boost the main ship. This proved to be enough delta-v, as once the landings were completed the ship cruised back to Kerbin, where they parachuted safely to complete the mission. - @AlpacaMall Mission here. This mission began with the launch and orbital construction of the KSS-J "Orca". Engineer construction added fuel lines and removed unneeded RCS thrusters, and the craft departed for Jool with a reusable lander upper stage, with lander stages for Laythe and Tylo. The landings were completed in the following order: Laythe, Tylo, Vall, Pol, Bop. From Bop, the Orca was left to serve as a relay station while the crew module left for Kerbin. The vessel landed with all the crew and 23458 science. - @BeanThruster Album here. This mission began with the launch of Vapidity, the mothership used during the mission. Instead of going to Jool, Vapidity made its first flight to an E-class asteroid so it could refill all of its fuel tanks (it launched almost empty to save weight). After flying to Jool, the first landing took place on Tylo, before leaving the engine nacelles in case later refueling was needed. Next, the last stage of the Tylo lander was used to land on Vall, then the lander flew solo to Bop where it awaited the rest of the ship. Vapidity took the time to take a spaceplane to Laythe, then went back to low Tylo orbit to refuel. Vapidity met the Vapidlander at Bop, conducted the landing, then went to Pol to do the same. Vapidity returned to Kerbin before the crew landed using the Laythe spaceplane. In total, the crew collected 20113.6 science. - @RuBisCO ISRU Album here. This mission began with a lot of mainsail engines to push the main craft into orbit, and delivered not one, but seven Kerbals to the surface of each moon. The first visit was Pol, where cleverly built piston legs kept the refueling craft perfectly level. Next was Bop, then Vall, then Tylo, where a rover and lab were brought to the surface and returned to orbit (except Tylo where it got left behind). For the Laythe landing, the crew took down a spaceplane, as well as a helicopter and a floating lab with plane-refueling capabilities. The helicopter was used to collect science from the local area, and after being refueled, the plane returned to orbit. After the main ship was refueled on Pol, the crew returned home. - @18Watt ISRU , Mission here. This mission is nearly identical to 18Watt's previous submission, but now has accommodated a unique Kerbal for each moon, bumping it from a 1st to a 3rd level submission. Main ship refueled on Minmus before heading to Jool, refueled on small moons, and pilots Val and Billy Bobfurt flew each unique specialist to their respective moons. - @Krazy1 ISRU, Album here. This mission was done with the Principia mod, which makes gravity and orbits behave more realistically. The spacecraft used was the "2 by 4", named after its two mammoth engines and four nervs. First the craft launched to Minmus, then visited a passing asteroid, then went back to Minmus to refuel, then shot off to Jool. After the Laythe landing, there was some trouble getting to Vall due to orbital issues. After Vall came a very bouncy Tylo landing, which was followed by a Pol landing, and then a Bop landing. It is worth noting that Bop is orbiting retrograde in this mod for orbital stability. After completing the landings and experimenting with weird orbits, the 2 by 4 traveled home, refueled on Minmus to prep for landing, and then touched down safely on Kerbin with its crew of 5. ISRU, Album here. This mission utilized an orange and gray aesthetically pleasing spacecraft. Once launched into orbit, the craft refueled on Minmus, then shot off to Jool where it landed on Vall, then flew to Tylo where it performed this landing, before nearly burning on Laythe, then finished up with Bop and Pol. Upon returning to Kerbin, some excess ore was turned to fuel to save weight, and the crew splashed down 10km from the KSC. - @Kimera Industries. Mission here. This mission's mission thread chronicles the Avocado on its journey to Jool's moons and back, using appropriately named components and landers. Due to its nuclear propulsion, the escape burn was split in two, though did not go gently into that good night, and upon arriving to Jool, took use of a convenient Tylo assist to go almost directly to Laythe. From Laythe, a lander was dispatched to Vall and Pol, then the entire ship reunited and migrated to Tylo where the landing was achieved on the fifth try. Next came Gilly 2.0 Bop, where an interesting SPOILER was discovered. Upon returning to Kerbin with little to no time for caution, the cargo container and its draggy friends kept the craft from overheating during airbraking, and the crew landed to live another day. Jeb's Level - @Xurkitree Grand Tour, ISRU Album Here. Collected 19,711.3 science from Jool on a girl's night out mission with no lack of gravity assists. A note from the author said that the mission greatly improved their skills in KSP and proved that fact well with the insane gravity assists they pulled off. Also first Jeb's Level on the new thread yay! - @ManEatingApe Video here. And here. And here. And here. And here. And here. Collected 16,532.0 science from Jool. There isn't anything I can say about this mission except you need to see it for yourself. Exclusively low tech was used, and collected in space science from all biomes. This mission did the near-impossible, with primitive parts, and landed all Kerbals safely back on Kerbin. - @SolarAdmiral Video here. Collected 42,296 science from the Jool System. Single launch on a cluster of three meter parts, before heading off to Jool. Started with Laythe first, landing using a floating platform. Science was collected with a small jet-powered boat. Next stop was Tylo, where a rover was used to collect science from many biomes. On Vall one landing was done, and a hop added to it before heading to orbit again. Numerous biomes collected from Bop and Pol by hopping around in their low gravities. Direct shot home and landed all seven Kerbals to tell the tale. Absolutely astounding mission! - @jinnantonix ISRU Video here. Collected 82,510 science from the Jool System. Single launch, one much smaller than you might expect. Used a plane to gather large amounts of science from Laythe, dove into Jool's atmosphere, grabbed science from almost if not everywhere, and even managed to use the Laythe plane as the final stage on the Tylo landing. Had an artificial gravity system to facilitate the kerbals, and landed back at the KSC. Honestly jinnatonix managed to do so much in this video I can't describe it all here so I suggest you just watch the video. Amazing job. - @GRS Album here. Collected 28,643 science from the Jool System. The long awaited Sheep mission that satisfied both the Kerpollo and Jool 5 requirements led by Simone Kerman that explored the Jool system and returned home Apollo style. The mission had a heavy launch and went to, around, and from Jool using a massive nuclear stage. The usage of the Scifi visual pack gave the mission a unique look as it took science from every moon (including Jool's upper atmosphere!) in style. Incredible. - @Jim123 Video here. Collected 8780.9 science from the Jool System. Single giant launch put a large nuclear mothership in orbit. Flew straight to Laythe where the landing was completed with a dual stage to orbit (and Jeb's jetpack). From there the crew went to Vall and landed, before heading to Tylo and dropping one of the most Kerbal looking Tylo landers I've ever seen to the surface. After Tylo biome hopping was used on Bop and Tylo, before a pair of service modules detached and went back to Kerbin, boosting each other home where the crew landed. Nice video. - @jost ISRU Album here. Collected 16940.2 science from the Jool system. Flew to Jool using a long nuclear mothership. From there an ion ore probe helped find ore on every moon but Laythe for the rocket lander. Laythe used a three seat plane for the landing, and even found a geyser while on the surface. Landed on Tylo with 1m/s to spare before refueling, and landed everyone safely back on Kerbin after leaving the nukes in a graveyard orbit around Kerbin. Excellent! - @Beriev Album here. Collected 49430.1 science from the Jool system. This entire mission was done in a 6.4x solar system. Launched off the pad with an absolutely enourmous rocket, fittingly dubbed the 'Absolute Unit'. Used many kicks to get out to Jool, where the ship split up to tackle the moons. For Laythe and Tylo, ascent vehicles were landed separately, before the crew arrived on-surface. Later, both sets met up at Vall, then flew to Pol, then Bop, and then to Dres. After a fun journey, the Absolute Unit returned to Kerbin, and the crew landed safely. This mission has an incredible execution and design, as well as a well-captioned Imgur album. I highly suggest giving it a look. - @Pro100kerbonaut Video here. Collected 10238 science from the Jool system. This mission was done with a rather interesting, asymmetrically balanced ship, and had quite the bouncy ride. On Tylo parkour was done, on Laythe swimming. On Vall two landings were done, and on Pol and Bop the lander bounced around. This mission used a combination of a gravity assist off Tylo and a retro-burn to capture at Jool, and upon return to Kerbin parachutes were attached to the crew section using a klaw. A fun mission with great editing. - @king of nowhere ISRU Mission thread here. Collected 105136 science. This mission was insane from its conception, with the goal to collect every single bit of science from the Jool system as possible. While this goal was not ultimately accomplished, the mission is still one of the greatest Jool 5 submissions I have ever seen. To collect science on each world, a durable lander known as the Dancing Porcupine was deployed and driven on all moons but Laythe. For Laythe, a spaceplane called Absolutely NOT Albatross was used to collect science from each biome. In fact, Absolutely NOT Albatross did even more than just Laythe. Using a multi-stage attachment, Absolutely NOT Albatross visited the lower atmosphere of Jool and returned to tell the tale. The craft's brave pilot even took an EVA report while in flight before ascending. The main ship dubbed the Flying Christmas Tree, and was capable of refueling on low gravity worlds. Upon returning to Kerbin, a craft launched to return the brave Kerbonauts to their home-world. Having visited every biome on every moon, it is no surprise that this mission amassed more science than any other Jool 5 mission before it. I highly recommend viewing this mission's main thread. Amazing job king of nowhere! Mission thread here. Collected 11395 science from the Jool System. The sheer amount of effort put into this mission cannot be overstated. King of Nowhere started this mission as a nanocristalline diamond caveman mission, which in short meant no contracts, no facility upgrades, no quicksaving, on career mode, while starting the save with severe limitations. While the mission ended up needing quick-loading, it still is eye popping to see just how much work went into it. Each launch (in the VAB) was limited to 18 tons maximum, so a work around was used by having docking ports around the base of the rocket, to which separate boosters would be docked using a runway-launched rover. This meant that many launches required multiple launches of booster attachment vessels before the rocket itself could attempt to leave the pad. After over 100 launches, the Navis Sideralis Neanderthalensis and all its cargo were ready, and the ship departed for Jool, leaving a most amusing pattern of drop tanks in its wake. Upon reaching Jool, disaster struck when the Tylo lander suffered an anomoly, and quicksaves were needed to complete the Jool 5. While at Jool, science modules were discarded after use because a lack of KSC upgrades prevented their resetting, and every aspect of the mission, from flying between moons to the landings themselves, were executed with meticulous testing and prior calculation. I cannot possibly explain everything this mission did in this little blurb, so I highly encourage anyone who wants to see some of the best Kerbal engineering I've ever seen to check out the linked mission thread above. ISRU Mission thread here. Collected 142744 science (Current Record!) from the Jool system. This mission is perhaps the greatest Jool 5 missions to ever fly. A worthy successor to @king of nowhere's previous submissions, this mission collected practically every single piece of science that the Jool system has to offer, with only a few dozen science bits unobtained. In addition, the mission visited every single anomaly in the Jool system, performed circumnavigations of every moon, and flew a two-crew craft into Jool's upper atmosphere to collect science, and deployed an aircraft carrier to Laythe. The mission's thread linked above follows the journey of the Flying Christmas Tree 2, a massive mothership capable of landing and refueling itself, Leaping Mantis, a rover designed for climbing steep grades on alien worlds, Tamarromobile, a larger rover for Tylo, Phoenix, the spaceplane for Jool, Absolutely Not An Albatross, an SSTO for Laythe, and Garibarge, the aircraft carrier for Laythe so that Kerbals could disembark from Not Albatross and collected surface samples from Laythe's ocean biomes. The mission began with Flying Christmas Tree 2 being equipped with the landers, planes, and aircraft carrier. Use this link here to see the majesty of Flying Christmas Tree 2 in all its glory -> (https://youtu.be/h61wplb0DRw?si=HlNYwxnYPkPaem2k). From there, it flew to Minmus to land and refuel, and then departed for Jool. The following efforts to circumnavigate all 5 moons and locating the anomalies require an entire thread of its own, requiring one to view and read the entirety of the mission thread linked above. Out of all the Jool 5 missions I have ever reviewed, none have exhibited such effort or gone to the extent shown here. This is not one of many Jool 5 missions, this is the Jool 5. - @OJT ISRU Mission thread here. Collected 26871.3 science from the Jool System. This mission thread contains some of the most eye-catching, visually stunning KSP screenshots I have ever seen in a Jool 5 submission. The mission itself was tested and proofed in sandbox, and consisted of a long, skinny mothership, a spaceplane, and an ISRU lander for Tylo. With the lander and plane hanging from docking points on the main ship, the craft boosted to Jool and used a Tylo flyby to capture. Visiting Vall first, the lander took around 100 days to refuel. The ship then flew to Pol where the relatively tiny lander (in relation to the mothership) flew to Pol's surface and back numerous times to refuel the main ship before it could head to Bop. At Bop a kraken was discovered, and on Tylo the crew found it refreshingly eventless. The last destination was Laythe, where the plane and lander were left in orbit so the main ship could return to Kerbin. A return craft returned the crew and science, and crew XP was had by all. - @Robin Patenall Mission thread here. Collected 61174.6 science from the Jool System. This mission began with the construction of the Emerald Star, a large and reconfigurable interplanetary vessel that required 17 launches to complete. Once built, the Emerald Star used Eve and Kerbin gravity assists to efficiently sling itself to Jool and started with Tylo. Using one of the Emerald Star's 3 drive cores to send itself down to a lower Tylo orbit, the lander successfully brought the crew to and from the Tylic surface. When the mission reached Vall, a magical anomaly was discovered, one which would prove to be only one of many odd discoveries made on Jool's moons. An SSTO found one on Laythe as well, during one of its three total landings. A monolith was found on Pol, and a deceased kraken on Bop, one which caused a crew member to lament their inability to bury it. Once the landings had been complete, the remains of the Emerald Star returned home, where it was parked in Kerbin orbit awaiting future assignment. - @problemecium Mission thread here. Collected 8755.7 science from the Jool System. This mission thread covers the finally completed tale of the Aletheia, a massive, nearly 1.3 kiloton mothership. With numerous cargo bays, it brought landers, an SSTO, a deployable space station, numerous pieces of scientific equipment, and two ARKS to return the crew to Kerbin if needed. Upon construction, Aletheia and its seven crew members proceeded to Jool, using 46% of its total fuel. The transfer section was left behind in Laythe orbit while the rest of Aletheia continued on. After Laythe came Vall, where one of the ARKS was used to refuel the Tylo lander to enable it to tackle Vall (the ARK was then joined to the deployable station and left behind). The lander then tackled Tylo, and was left behind for future use. Bop saw the discovery of a hopefully deceased Kraken, and Pol marked landing number 5. This romp unfortunately depleted Aletheia of the fuel sufficient to return to Kerbin, so the second ARK spacecraft brought the crew home safely, using a Mun assist to tweak its final trajectory. This is one of the more aesthetically pleasing Jool 5 missions, and done in career mode in a very well typed out and necromanced thread, so if you are a fan of large stylish motherships, I would recommend giving this thread a view. Gatecrashers / Honorary Mentions - @JacobJHC Grand Tour, video here. Giant single launch craft, also visited every planet and moon from the OPM planet pack. Very big. Gatecrasher because crew hasn't landed yet. - @Fraus Mission here. There's nothing that can be said about this, other than that this mission definitely had more thought put into it than any other Jool 5 I've seen. - @cqIpb Mission here. This mission was flown on an Xbox, and pushed the console to its framerate limits! cqIpl was inspired to do a Jool 5 mission after finding this thread, and despite not being able to land on Laythe due to lander instability, still had a lot of fun finishing the rest of the mission, and took a few great screenshots along the way! As of writing this, cqIpb is still new to the KSP Forums. Welcome, we're glad you're here! - @Alpaca Z, using a craft built by @Lt_Duckweed (with permission) Grand Tour, ISRU . Video here. Using a rather simply built SSTA, this mission was a simple case of flying around the entire solar system and refueling everywhere. This craft utilized air-fans, ions, vectors, and nerv engines, allowing it to be not only capable of high efficiency maneuvers, but also those requiring high TWRs. A highlight of this mission was the strategy to use EVA construction to rebuild the back of the plane to enable it to land vertically on Tylo's surface. Why bring landing legs when you have wings that could do the job just as well? This mission's video submission is also of a high quality, so I recommend giving it a view. In all, the crew of three finished their grand tour in only 15 years and 117 days! Efficient and speedy Moved to Honorary Mentions due to the fact that the crew could not exit onto Tylo's surface.

I used to post on this forum in 2014, back when I was 13, and things have changed a lot since then. What never changed, though, was my love for KSP. And I decided the best way to show my love for KSP and make a return to the forums at the same time is with a mission report, as I've always loved those. A video game is about gameplay anyway, is it not? The mission in question I'm posting about is a Science Mode mission. It was a well-planned and fruitful fly-by of Minmus, that of which rewarded me with a lot of science points. Everything from ascent to landing was nominal, and I had enough delta-v thanks to using drop tanks (which I would highly recommend if you're looking for ways to get more delta-v) that, by the time I had reached a circular-ish (as in not perfectly circular) low orbit around it, I was eager to attempt to make a landing, but knew that a lack of landing legs might have spelt out stranding Jeb on Minmus, so I decided not to do that. The Experiment Storage Unit's ability to store science stuff truly came in handy on this mission, because, without it, I wouldn't have been able to store multiple experiments how you can't if you don't have it. That's how I was able to store eight experiments instead of the lower amount it would have been restricted to. The placement of the ESU indeed made the final re-entry stage taller, but it had no noticeable negative effects, as I had postulated that it wouldn't. As far as water landings go, I actually landed quite close to shore, with an impressive amount of science points to boot. Talk about a successful mission, eh? 203.1! That is no joke compared to the much more modest numbers that I used to get. In fact, the type of stuff that I can do now is what would make the KSP poster me from something like ten years ago as of writing this very impressed about it. It's moments like that which remind me why I fell in love with this game in the first place. As Jeb safely touched down near the shores of Kerbin, I couldn't help but feel a profound sense of accomplishment. The science points gathered were impressive, marking a significant leap forward in my pictured Science Mode career within KSP. Reflecting on the mission in retrospect now as I wrote this post, I can't help but marvel at the advancements in my gameplay skills since my early days of basic missions done on pirated copies of Kerbal Space Program. This time, every decision felt deliberate and informed, from the choice of using drop tanks for extended Delta-v to the careful management of scientific data with the Experiment Storage Unit. From the KSC launchpad, Jeb's spacecraft soared into the Kerbin sky, its design meticulously plotted to optimize delta-V and fuel usage, hence the drop tanks. And with the precision of a seasoned veteran Kerbonaut, Jeb soared gracefully towards Minmus in his spacecraft, fueled by the aforementioned drop tanks. The decision not to risk a landing without proper equipment showcased Jeb's commitment to safety and mission success, a decision that later proved wise as he navigated doing science work above the icy landscape of Minmus from a cautious yet cozily close orbit instead without a hitch, with more than enough delta-V and fuel to spare. The Experiment Storage Unit, smartly integrated into the capsule design, stored a treasure trove of scientific data from multiple experiments worthy of earning nods of approval from the Kerbals at the KSC back home. Especially from the scientist Kerbals over at the Research & Development Facility. Oh, and let me tell you about the return burn from Minmus! Funny thing that. Jeb's was cruising back towards Kerbin, and everything seemed on track, right? Well, the maneuver that was done for that had put me in a unique position that I was not expecting it to — a slingshot course from Kerbin to the Mun and back! Now... normally, you'd think, "Hey, free Mun fly-by, cool!" But, nope... not this time — I had over 100 points of science on board from that epic Minmus trip. And I was not about to risk losing all of that. So, instead, I slammed the brakes, metaphorically-speaking, using a retrograde burn and rerouted into a smooth re-entry trajectory instead. Sure, it would've been awesome to swing by the Mun and back, but science is science, folks. And when you've got that much valuable data packed into your capsule, you play it safe. Although Jeb may have missed out on a Mun adventure, it was ultimately way more worth having those science points safely tucked away than to risk it all. KSP's all about calculated risks, and this time, caution was definitely the name of the game. Jeb might be a daredevil in space, but I feel like even he knows when it's time to play it safe for the sake of scientific progress. Anyway... that's all. End of mission report story. If you're reading this, I want to thank you for sharing in my excitement and passion for Kerbal Space Program. My thoughts that the Kerbal Space Program community is truly something special have remained unchanged, and I'm glad that a lot of you folks are still here. I look forward being part of the KSP1 community again, as an adult with advanced knowhow now, as well as sharing more adventures with you like this all soon. I'm glad to be back, and more than curious to hear what all of you here at the forums have to say — especially after not having made a forum post before this in so long. And, plus, my fingers have started wanting to type words about the serious business that is putting cute little green creatures into space more than ever. Here's to the many more missions, discoveries, and discussions ahead. Fly safe, aim high, and may your orbits be ever stable! Cheers, Qwotty

Of course, and thank you for teaching me where the Kerbal Network is, as I had a feeling that I was posting in the wrong spot but didn't know where to post. By the way, I suspect what happened has something to do with the aforementioned Unicode Character "GREEK CAPITAL LETTER DELTA" (916/U+0394) not being natively supported by the forum. If the site does not support emojis then it would logically follow they don't support certain special Unicode characters, as that's essentially basically somewhat what an emoji is in a technical sense anyway. I don't even think it's that big of a deal, personally — more like it's funny that a mere inclusion of a delta triangle can mean not being able to make a post, considering I'm sure people talk about delta-v all the time on here, as they have been for many years.

Thread title makes it look old, and some of the patches will certainly be from an earlier time in the development of MM, but I imagine it is still the best place to keep that info consolidated and to talk about best practices.

its a seam in the textures but idk why it appears here the current config is basically just stockvolumetric clouds tweaked a bit so idk it doesnt appear in stock ill talk to blackrack about the sunflare issue i noticed it as well

Ever since the news dropped, things here in the forum have been rather depressing. Negative, questioning what is happening, attacks on other forum members. Things have taken a turn for the worse, and it makes me sad. We were hungry for KSP2, and in spite of its problems, we played it. Fired it up, dealt with bugs, went on missions. Some people are still playing it, and are still creating oddities. @ShadowZone released a video recently where he flung the four OG Kerbals into the farthest recesses of space. spacetime development might be dead, some people are still playing and getting enjoyment. With that said, I'd like to try something new here. I'd like to have a thread where people talk about things in the game that made them feel happy or good about it. Was it some mission you flew? Or perhaps a discoverable you, um, discovered? Something the game has that you didn't realize before that made you think " all righty then!"? I will start. I've got more than 1000 hours in KSP1, but I had never flown to Jool before. I've been to all the other planets, and landed on all of them. Notice I said landed; I still have not gotten back off Eve. But in KSP2, thanks to For Science!, I flew to and landed on Pol, Bop, and Tylo. I was able to return from both Pol and Bop, while leaving a rover on Tylo. Landing that rover on Tylo was the single biggest achievement in my KSP playing time. I'd like to ask that anyone who responds here to please only talk about things in KSP2 that you either never did in KSP1, or that made you feel good about the game. Nothing negative! We have a ton of those threads already; I do not want this thread to get locked because it dives into what is wrong or that TT is evil. Positivity only!

KSP 1.10.x Mark IV Spaceplane Fuselage [3.1.2] Last Updated August 3rd, 2020 This part pack adds a new lifting-body fuselage system for aircraft heavily inspired by an iconic 60s sci-fi design. It's designed to fit 2.5m parts in a cargo bay easily, and 3.75m parts snugly. The parts are done in a stockalike style and I've attempted to be as close to Porkjet's Mk2 and Mk3 parts as I can.

Boy I sometimes hate how Gramerly and Firefox interact... soo many problems with THIS and ONLY THIS Forum. Sorry, to answer your question Entr8899, do a full send. If it works great, if it doesn't then revert the launch. None of these rockets are perfectly scaled. Some are pretty close to Scale Factor X, Some are close to scale factor Y, and others use yet further scale factors to bring the parts to a lego-able playable experience. That being said there are just sometimes things be like this. Could it have been made "more playable?" MAYBE...but not certainly! But making it more "playable" will throw the scale off of other things and people would rage about that. In the end the BDB Team has to choose what they feel/hope is right and just do it. A great example of this is while it is the correct design, the Agena Interstages almost all of them clip if anything other than *edited* the SPS are attached to the Agena aft rack. And it is not like we are paying CobaltWolf, Zorg, InvaderChaos, Roger, and when they were active Jso. Each of them volunteers their work and more importantly time. Time is a thing few of us have a lot of free to do this stuff. I kind of wish Cobalt was still doing his "Dev Streams" like he used to so a lot of new players can see just how hard it is to actually make these things look as awesome as they are! A great example... The Titan IV upper stage, took 2 or 3, 3ish hour Streams for ONE color choice as I recall. The amount of effort put into these parts is amazing. I was helping (well trying to help) to find reference photos for the Atlas rebuild FOUR YEARS AGO... That is when Zorg started the Atlas refresh. Zorg can talk to how much time he spent reaserching, and how much time he spent designing and then modeling. But suffice to say it started 4 years ago It is for this reason I only asked for a node to be added to the Existing GEM-60 SRM to work with the new Atlas V SRM decouplers. Because the time it would take to rebuild the GEM-60 to match current standards would be a lot of work! And the GEM-60 is a pretty simple part.

Wow. Talk about frontal area drag. With weight shifter aft given an bay empty on return the lower shuttle cocking of the short and wide airframe is surely spooky to pilots, I'd imagine

That is wildly exaggerated, TBH. Your typical interplanetary transfer is in tens of km/s. A 2RPM rotation involves a rotation around a point 250m from the center of mass (this can be more or less than 500m of cable, depending on your counterweight, naturally) and has velocity w.r.t. combined CoM of only 50m/s. This is well within the mid-course correction burns you'll be doing anyways. Likewise, loss of gravity, while disorienting, is about as dangerous as riding on a drop tower at an amusement park. You do still have the spin of the rocket itself, but it's likely to be a fairly stable rotation and the resulting centrifugal effects will be minor enough for this to be at worst comparable to a slip-and fall on flat ground. You can never exclude a risk of injury in any sort of a fall, but you can also slam your hand closing a hatch, so you know. What is a real risk is the cable snap-back. Back of an envelope estimate, a lot of materials you'd consider for a cable would stretch by about ~10% before failing. You want a good safety margin, so you're probably going to be looking at a little less than 5%. Call it a 10m stretch from CoM, where the cable's most likely to snap. A fully-fueled Starship is 5kT, which means you're looking at 1/2 * 50MN * 10m = 250MJ of energy stored in the cables. It's not a LOT, but it's enough to get the tip of the cable flying at you at a decent speed. (Yes, I know the energy is split between multiple cables, but so is the mass of the cable you have to get moving...) With a very rough estimate of 20T of cables in there, you'd get something like 50m/s average speed, but the tip is likely to be traveling closer to the speed of a bullet. The odds of that tip hitting the ship are not zero, and it will absolutely slice clean through. There are safety measures you can take. The tension wave will propagate at the speed of sound through steel, which is on the order of a few km/s. That technically gives you enough delay for emergency severing of the cable. If you put accelerometers everywhere along the length of the cable, you can cut all the cables from the ship, causing both ends to snap together instead, resulting in very low chance of any part of the cable hitting the ship with significant velocity. You obviously want this system to be rock solid, but what emergency system isn't? And we are looking after a catastrophic failure, which is very unlikely to begin with. We build suspension bridges using essentially the same tech. All of that said, when people talk about testing a centrifuge on ISS, people do talk about small radius centrifuge. As mentioned earlier in this thread, we do now have strong evidence that even a sub-5m radius centrifuge is viable for artificial gravity with a trained crew. Especially if you don't mind ramping up the speed over a few days when the trip starts, and winding it down on arrival. And that is an entirely different structure. Something with a revolution period of about 4 seconds and compact enough to fit in the inner hull of the Starship. If we're going to see artificial gravity on a trip to Mars, that is far more viable than any tethered design. And it's also something we can comfortably test on the ISS with very reasonable expense. I mean, it's still a full sized module requiring some amount of orbital assembly with current launchers, but again, if we're looking at testing this for interior of a Starship, the best way to test it would be to assemble one within the Starship, dock it to ISS, and just keep it docked for a few months. What better proof of Starship's capability to take a crew to Mars could you possibly ask for?

Okay I first reported this (nothing against you) for possible off topic. Since I'm back from work and it is still here, I take it discussing game launchers in this thread isn't off topic, unless you're allowed and I'm not, so here it goes: Epic offers free games, and that's where the positives end. Steam's forums are flooded with Epic customers asking for support since Epic doesn't offer a form of discussion or contact. They've let their store be flooded by crypto/nft scams after forcing all users into arbitration with a new EULA, compounded with the fact their human support is abysmal. Even if you chose to not purchase there and submit yourself to a subpar experience on anything that isn't giving them money, they've been a cancer for gaming and games: Helped bring Tencent to the West. Buying off and then killing/forgetting about studios (like fall guys too). Scamming people with the Save the World mode on Fortnite. Bringing exclusivity wars garbage to PC, though devs are slowly realizing that people just don't buy games on Epic, most recent funny failure being Alan Wake 2. They talk about giving better shares to the devs but some of those some extra costs of transactions are pushed onto the player. Their account security is subpar garbage. <- Did you know they deleted their own report? just found out whilst sourcing it. Still, here it is. They started off their "famous" sales by not telling the devs they'd devalue their games. I could probably go on for longer, and that's just on the player's side, if you check on the dev side... But hey, they give free games, and people are free to choose. Finally, to keep topic-relevant, the points about their human support being subpar applies a lot to trying to refund KSP2 past the arbitrary refund window (impossible through Epic, hit and miss on Steam), and the quality of the store and guidelines for publishing games is what protects Take Two from leaving an unfinished, soft canceled "early access" game in there with zero fear of repercussions.

To go back to the topic, I'm surprised that the original suit-makers for Apollo are unable to deliver on-budget. I remember one literal high-flying rich guy asked them to build him a high-altitude suit... *searches* Alan Eustace! He did a TED Talk about a high-altitude jump in 2014 about ILC Dover, not Collins, making him an environment suit that basically dangled him and the suit from a high-altitude balloon to avoid the mass of a capsule. https://www.ilcdover.com/aerospace/spacesuits/ This proudly proclaims, "Anyone can try to make a spacesuit. Only ours have been to the moon." Oh-kay. But who's building the current suits? *more searching* It seems the turducken of mil-industrial goes like this: RTX owns Rayethon, Collins and Pratt & Whitney Collins subcontracted ILC Dover (Apollo suits) and Oceaneering (oil, gas, wind turbine platforms, ocean ROV and subs) to make the xEVA suits. Makes sense. However, ILC Dover was recently bought out by Ingersoll Rand, who seem excited to use them and their equipment for their pharmaceuticals industries. Barely a peep about aerospace.

I did not talk about conjecture or anything. You're not arguing against my conclusions, what you're trying to run against now, is word from producers, engineers, and other various developers and employees, you're trying to tell them that their game is not dead even though they've been looking for a job for at least a month for the freshest out the door. You're contradicting the news and the statements of anyone official but the CEO. So yeah, you're only playing for the guy that is set to make money of off not saying the game is dead, and expecting him to say the game is dead. It's not just a bad argument that runs against reality, it's naivety.

As I was saying, the agnostic argument. It's dead officially, they just haven't said the one specific thing about it you want them to say in the way you want them to say it, which is most probably not gonna happen. The office was closed, confirmed by the WARN. The people that worked on the title are all fired minus Nate which is the only person we can confirm was absorbed into PD. Effective this Friday. Confirmed by the WARN and later on by some employees themselves, and one of the KSP2 producers. Some people were fired even before all this debacle without anyone new replacing them. Confirmed by Wes and later on the SZ video. They updated the game to complete the credits and remove the branded launcher. Don't think I need a source here. They've ceased all talk about future updates. Again, you can just check the forum, and other places too. They tried offering the IP with or without the studio for sale, and they tried offering the whole of PD for sale too. As confirmed by news. Now, that's direct evidence, i.e. not conjecture or hyperbole or theories or whatever. Your "proof" is asking a rotting corpse to climb out of its casket and tell you "yes pal I'm pretty dead". Not only does the corpse provide enough evidence of its death already, it's also very unlikely that there's any life left in it for it to raise up and give you the answer. And I've put my money on Factorio, Space Engineers, DRG, Besiege, Barotrauma, Rust, Rimworld, Beam.NG, KSP1 and many other successful, fun, fulfilling EA projects that have been a pleasure to be a part of (well, KSP1 not so much). On the other hand I've also paid up for this garbage, StarForge, Stormworks, Hydroneer (was fine until the multiplayer update), 7 days to die, and many others. It is definitely not a system that guarantees success, or even something as basic as a good game. But it is also a system that lets you be part of great stuff and enjoy great games much before others get to it. And yes, you're very right in saying that $50 for an early access is a huge red flag. Wish more people had listened back then, and I'm very thankful to Steam for regionalized prices and to every dev/publisher that uses them correctly.

KSP 1.12.x Near Future Propulsion [1.3.5] Last Updated August 26, 2021 This pack contains advanced electric engines for deep space travel. Generally engines split into the following categories: Gridded Ion Engines: like the stock Dawn, they have low TWR and great Isp. They run on Xenon fuel. Hall Effect Thrusters: similar to Gridded thrusters, but with better TWR at the cost of some Isp. They run on Argon fuel and are pretty cheap! Magnetoplasmadynamic Thrusters: with the best TWR of all electric engines, these engines are very power-hungry. They run on Lithium fuel. Pulsed Inductive Thrusters: similar to Hall thrusters, they run on Argon fuel and have the unique ability to dump extra electricity into the engine, increasing Isp but generating more heat. VASIMR Engines: high tech and fancy, these engines run on either Xenon or Argon fuel. They can be tuned for high-thrust, low Isp operation, or low-thrust, high-Isp operation These engines are all very power hungry - use nuclear reactors or high intensity solar to get the power you need. Their balance has been finely tuned to work with stock mechanics and to extend the KSP experience, particularly in combination with the Community Tech Tree.

I think it was found out in its own time. There is a thread of talk among the sci-fi / fearful / weird crowd to the effect that 'humanity is destined to destroy itself'. The companion to this is 'the reason we don't talk to Aliens is that they've all destroyed themselves.'. Apparently (according to the line of thought) once a species acquired nukes it is inevitable that they will destroy themselves. That is probably hogwash. The '23d century tech' bit is the key: they think that somehow, magically, by the 23d century that we would be so enlightened as a species that we could handle the awesome responsibility of having such terrible weapons. If you recall your Star Trek canon, there was a terrible nuclear war, which humanity survived, and two centuries later we were bigger and better than ever. (might also be hogwash)

Matt Lowne said, during his conversation with Harvester on the Tube, that he'd reached out to Nate and got a response saying 'I look forward to talking when I can' or something along those lines. Reading between the lines there, he can't talk right now due to some mitigating factor, no doubt a non-disclosure agreement but it sounded like he'll be able to talk sometime in the not too distant future. If there's anyone who has the full details, it's Nate.

This is a pretty simple thread, you just talk about what you did today. It can be in games, but not ksp as there is a thread already for that. I went to our local mall because I have money from Christmas and wanted to see what I could get. I looked around, my indecisiveness led to me not getting anything. After that I looked for DnD books at a book store near us. I didn't do much else, a lot of sitting on youtube. I also have a bit of a sickness.

https://arstechnica.com/space/2024/06/ars-live-recap-is-spacex-a-launch-company-or-a-satellite-communications-company/ Transcript of talk here: https://cdn.arstechnica.net/wp-content/uploads/2024/06/Starlink-Conversation-Transcript.txt tl;dr With Starlink, SpaceX is the largest satellite operator in the world right now, both in sheer numbers of sats and ground stations, and in revenue: Viasat/Inmarsat and Intelsat/SES ~$4 billion, Starlink $6.6 billion. They have a foot in the door with Indonesia, which is a prime market for satellite internet. If they enter India, despite the recalcitrance India is showing to OneWeb, that's an even bigger market. Estimated launch costs are below $20 million.

Again, we fall under the same disagreement: If your boss tells you to do bad work, and you just follow his instructions, you are a bad worker. I understand office politics and lazyness leading to you to just follow those orders because it can prove beneficial, however you don't get to also complain about the state of the industry, layoffs and what not when you're being exactly part of the problem by taking 4 weeks to produce some basic code. So when you're cleaning house of bad apples, you need to fire the musicians, and the people ready to dance to them. Sadly, when most of these layoffs happen, they fire only the dancers, but some very scarce times they also fire only the musicians. I don't remember a case where both get the boot. Voting with your wallet can be completely irrelevant depending on scale. In our current case, even if we round up everybody left in this forum and the discord (~1000 active people) we'll never get TTI to do anything about it but laugh. This is my last message on this topic as I don't want to do off topic. If we can continue this talk, hopefully it'll be on another thread that isn't sent to get lost in the shadow real of irrelevant subforums.

i renumber burt rutan's tech talk about how fast we went from shoddy gliders to landing on moon, and that the past few decades have done nothing nearly as impressive as that burst in development. with spacex and others pushing the envelope again, this slump seems like its to come to an end. these kind of development cycles seem to happen in bursts. we just get to the point where we dont feel like barking up the same tree even though there might be juicer fruit on the higher branches. nuclear is in a similar situation and because of a couple bombs and 3 accidents at powerplants were afraid a coconut will land on our head and we leave that tree alone. based entirely off the half a paragraph i managed to read before my eyes wigged out. also i do kind of like the idea of winged boosters. its kind of the role skylon should be designed for rather than ssto. it doesnt even need to go to orbit or even build up enough speed where reentry becomes a hot mess. it just needs to loft stage two high enough so it has time to complete a circularization burn. of course the end result to that is an overcomplicated falcon that can take off from any airport. what we need to do is figure out how to make that kick stage recoverable. but it has to deal with the same issues that starship does. so again it feels like a hard way to reinvent the wheel. still the landing part of reusable second stages is going to be a huge problem both here and on other bodies (heat shield is still an issue but it looks like we have made some headway at least, eg move the flap roots leeward as planned, even make them retractable, eg on linear bearings). think we really need to start looking at lateral engine mounting, except now the turbopumps have to be able to move propellant half way up the ship under thrust gravity. as a second stage this can be reduced depending on whatever loft time your first stage (winged or otherwise) gave you. also fine for lifting off of moon/mars and keeps the regolith out of the engines. but then your structural loads from thrust need to be handled and more mass required (possibly also from a slightly bigger turbopump) again less of a problem at low gravity (real or otherwise) but you must also support the weight of the engine. and losing one of the two pods would be bad. multiple engines per pod would be better but then you need to isolate them better so you dont get a cascade failure in the pod. complex geometry like this also makes re-entry problematic (see starship's liquid metal flaps). heat shields like to be simple.

Here where I live, we call this the Mediocrity Pact: you pretend you are doing meaningful work, I pretend I'm doing meaningful work, and we cover our arses so no one will caught us. 10 to 15 years ago, I was hired on a Industry to help code some firmware - not going to give too much details on this one, you will understand soon. First thing I did: I spend a whole week reading every single piece of technical paper the project had, including protocol specifications. Second thing I did, I specified exactly what I would be doing, feature by feature, with alternative paths to handle the expected exceptions. It became a PHD thesis compared to the specification documents they were used to. It took me a month and a half, a time my immediate manager wanted me to do some coding. But I had someone above him getting my back, because I did my way nevertheless. On a conversation, with that manager visibly nervous, he bluntly told me that I was going to be responsible for that use-cases, and I will be responsabilised if the use-cases would not be validated by the QAS team. I remember looking at them with a puzzled face (or at least, it's how I felt my face's muscles) and asked: "And there's any other way to get the job done?" TL;DR: The Company had outsourced the development of the product to a company (mine), but also outsourced the QAS to a direct competitor. So it would be the best interest of that competitor to get rid of us to score the positions for their own contractors. So my direct manager's problem was that he had hired my company to the development job, and he didn't wanted to lose points on his boss if we fail on the job - what, in theory, would be our competitor's best interest and, so, writing a so detailed and specific Requirements would play against our best interest. Problem: such Requirements was still the best (if not the only) way to get the fracking job done! What follows was probably my finest hours on that Industry: I had already worked for that Company, so I knew how they think and I understood why they hired competitors for Development and Quality. TL;DR: if the project fails, BOTH OF US would be sacked, so we were all in the same boat. So my next task, after writing that document, was to talk with the QAS guys and explain to them (including their manager, that understood and agreed) that our best interest was to work together in this project, and let our respective bosses to handle politics up there in the top floor - far away from the trenches. I did everything I could to make their lives easier, and they made everything they could to make my job effective (not exactly easier however ), and we delivered the product not as specified, but better. EDIT: I want to stress the pronoun WE. I didn't saved the day, I just did my job while they did their job and together we delivered the product. Unfortunately, that project was an exception on our Customer, not the norm. That Industry had already started to crumb - in the exact same way this one is doing now. It's the reason I think the Game Industry is "over firing", not to mention firing the wrong guys. The real troublemakers depicted by this video are not the cheeks-covering developers that wanted 4 weeks for a simple task. The real culprit is the idiot that negotiated the 2 weeks. Get rid of that idiot, and the developers will just cope with the demand, or they will be punctually replaced - and problem solved. It's exactly about "seniority". Under par people were hired as "Seniors" without the merit. And these people climbed the corporate ladder and started solving technical problems with politics. Firing the people that danced with their music is not going to fix anything. You need to fire the musicians.

You guys are just as mixed up in all of this as us, so of course it's no slight toward the mods, bug hunters, et cetera. More towards Take Two Interactive, the problem is it will go unanswered. There's few things worse than purgatory, for better or for worse it's time for someone to talk about it. I suppose once the WARN deadline passes, the end of this month, the likes of Nate, Nertea, et cetera are free to actually talk about it. It's a shame because if there's one thing I could and would never accuse Nate of being, and that's not absolutely enthusiastic about 'the work'. The dude seems like he genuinely loves the concept, the Kerbal way, to the extent that he kinda angered the community a bit with their decision to have wobbly rockets. But yeah!
