About me



  1. 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. 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 (Current Record!). 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. 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. - @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. 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 (Current Record!) from the Jool system. 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 (if not) 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. This is my favorite submission to the Jool 5 Challenge I have ever reviewed. 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. - @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. 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.
  2. Hello everyone! I recently flew a Jool 5 mission that, as the title says, was done in one launch. Here's how it went. I'll be uploading the report in seven parts, with (hopefully) one per day, for each leg of the mission: from Kerbin to Jool (this one), one for each moon, and return to Kerbin. Part 1: Launch! We begin on the pad with this massive rocket - nicknamed the "Colossus" - that appears to be almost half fairing. I don't have either DLC, so Mammoth spam (Spammoth?) it is. The two boosters, connected to the core via fuel pipes, will get the rocket off the pad before separating and letting the core carry it to a suborbital trajectory. There's also an extra Vector that's been attached to the bottom of the core stage, because the TWR was far too low with only the Mammoth. All systems are nominal, staging triple-checked, and Val, Bill, and Bob are all on board. We are clear to launch. Liftoff! A fairly standard gravity turn. Booster separation! The core stage will carry us to a roughly 100km altitude. The core stage is empty now and the Rhino will take us to orbit and beyond. Our apoapsis is just above 100 km. Fairing deployed and the interplanetary craft is revealed! It has a small SSTO for Laythe, a two-stage Tylo lander that will refuel for Vall, and an ion lander for the two outer moons. A 350 m/s circularization burn puts us into LKO. Launch happened at a Jool transfer window, so we're able to plan our Kerbin escape burn immediately. Two staging events will happen during this burn - the Rhino engine and the lower liquid fuel tank will both be dropped. And here are those staging events now. Goodbye Kerbin! The crew plans a correction burn and Tylo gravity assist in deep space. We want our periapsis to be nice and close to Laythe's orbit, and the apoapsis not too far out. As you can see, this required a close scrape with Tylo. (the second maneuver there is only because KSP doesn't like to show my trajectory beyond Tylo's SOI when plotting an assist from Kerbin or interplanetary space unless I put a maneuver node in Tylo's SOI. I deleted it right after the correction burn.) Hello Jool! And hello Tylo, too! The aforementioned close scrape of Tylo. The crew will be getting much closer soon with that lander in the back, but for now the moon has done its job. Val, Bill, and Bob are safely captured around Jool. And with that, the crew is in a stable orbit around the green giant. This is all for today, but I'll be back tomorrow with what was arguably the most annoying part of the whole mission: the Laythe landing.
  3. Send Val to vall To complete this goal, you will have to send Valentina Kerman to Vall (I got this one from the loading screen, I spend a lot of time there) Plant a pole on pol Goal is simple. send a kerbal to pol and plant a pole (flag pole) on pol! Laythe lazy Very relaxing, simply make a kerbal take a bath in laythes water. Rules: 1. You must not use cheats of any kind. 2. You must take a screenshot every time you enter and exit a sphere of influence, land on a body and when you launch/return to kerbin. 3. You must not kill any kerbals. 4. You must have fun! if you do not follow one or two of these rules, your mission will still count, but points will be deducted. Community Challenges Tylo low flyby Fly by Tylo as fast and low as you can - Superfluous J Bop on Bop This challenge has 2 parts to it. First, send a crewed lander to Bop and perform a hard landing. A hard landing is defined as anything greater than 2 m/s, but you should be aiming for as hard of a landing as possible. You know, you are trying to bop Bop (like landing a punch). The second part is to take that crew and get them on the surface and dancing around. Gotta have at least 3 Kerbals present to call this a party. - Scarecrow71
  4. Goals: Primary Goal: Flyby of Jool and return to Kerbin Stretch Goal: Land on any of Jool's moons and return to Kerbin Jeb-Level Goal: Land on Tylo and return to Kerbin Val-Level Goal: Land on Tylo, Laythe and return to Kerbin No Cheating! Any submitted attempts with infinite propellant or any other cheats will not count! Prove your run is real! If you are going to submit an attempt of any of these goals, please prove that you are doing these, by showing screenshots of landings, flybys and entering spheres of influences. Thank you for complying, good luck :)
  5. I decided to show off ksp2 to a friend of mine and he asked me to try flying into Jool. I was curious as well, so I built my ship and went on my way. Well, as I flew deep into the atmosphere, I randomly decided to try EVA. You know, for science. Umm, Bill's shuttle literally just... vanished, and he was left simply flying deeper and deeper into the atmosphere, as the sun fell behind the horizon and everything became entirely black. He flew for several minutes until... he simply LANDED??? I even placed a flag Something tells me this wasn't an intended feature...
  6. I had a rocket set up for a duna mission but forgot to get a good transfer window, so I went to jool! I've barely done a manned Mun landing and am already getting to Jool. I'm freaking out right now. I don't do manned missions outside of Kerbin orbit, so this is unmanned, but I still feel really proud.

No. There is no part limit. How much science do I have to get? Just run all the experiments (expect the seismometer). Can I use planet mods? No. But I will allow the Outer Planets Mod. Please contact me for any other though. How do I contact you? Message me through the KSP forums (Tip: Ping me through the forums message feature.) Is there an age limit? No. Anyone can participate in this challenge. What versions can I play this in? You can play this version from 0.8v to (CURRENT VERSION) Can I play this challenge in the DEMO version of KSP? No, the demo version doesn't have Jool added yet. Is there a maximum amount of submissions I can make? No. You can do this mission as many time you want. Can I make a video of this challenge and monetize it? Yes you can. I'm not sure why you would think I would say no. Can we use MechJeb? Um. This is a hard one. I would say no. I think MechJeb is automated so I will say no. Can we use MechJeb2? Um. This is a hard one. I would say no. I think MechJeb2 is automated so I will say no. Can we use Better TimeWarp? Yes. You can. Can I edit the save file to make it easier? No. You may not edit the planets orbits or position to make this challenge easier. Can I use visual mods? Yes you can. Mods like EVE, PARALAX, and Stock Planet Enhancements are allowed. How can I contact you about the rules and modes? Please message me through the forums and we can work something out. Is this possible? Some of it yes and some of them have never been attempted before (as of May 2021). So you might as well be the first. Where does Jool's atmosphere begins? It begins at 200,000 meters (or 200km) above sea level and 200,000 meters (or 200km) above terrain. What is "km"? The acronym "km" means kilometer. Conclusion I hope you enjoy this challenge. I wait to see the ideas you come up with. And the reason why I submitted this challenge is because. Kerbal Space Program the the community always break something once in a while. Making the impossible, possible. And lets revisit this old friends, and finally shows the Kraken who is boss! Like how we (humankind) went to the Moon. Not because it was easy. Because it was hard.

  8. Is it even possible? The challenge is to create a rocket (or many rockets) that can get to Jool orbit, only using sepratrons! This is my first time doing a challenge, so things might be a bit weird. RULES: 1. Don't use exploits. 2. No RCS 3. Gravity assists are allowed, as long as you get to Jool. (suggest more please) Categories (points are a work in progress): Jool Orbit Unmanned: Get to Jool orbit using a probe (100 points) Jool Orbit Manned: Bring a kerbal to Jool orbit (200 points) Jool Probe Descent: Send a probe down into Jool's atmosphere once you reach Jool orbit (parachutes allowed) (175 points) Jool Probe Return: Send a probe to Jool orbit and back to Kerbin safely Jool Manned Return: Send a Kerbal to Jool orbit and back to Kerbin safely (300 points) Badges: (work in progress) Leaderboard: Jool Orbit Unmanned: N/A Jool Orbit Manned: N/A Jool Probe Descent: N/A Jool Probe Return: N/A Jool Manned Return: N/A Have Fun!
  9. This post is reporting about my Jool mission, which will be assembled in 3 launches and primarily orbit Jool for a few months (Specific times will be layed out as the mission progresses). GameDate folder: the crafts: Prometheus 1 First of all, the launch vehicle that will deliver the modules of the ship is called "Prometheus 1". Its payload capacity is about 200t. The Rocket consists of 6 5 segment SRBs, 19 main sail LF/O engines on the first stage, and 8 Raptor Vacuum engines on the 2nd stage. The screenshots are taken of the baseline configuration which will launch most modules, however the propulsion module will be launched with a stretched upper stage. THe centrifuge module will be launched on a 10m diameter upper stage. Front View: Side View 1: Back View: Side View 2:
  10. Is there a mod which changes the colour of jool into something which is more realistic and Jupiter like, e.g. orange and brown instead of green. I know that green is a very good colour for ksp (since kerbals are green anyway) but i'm looking for a mod which can add more realism to the stock planets without replacing them entirely. I found this thread but it is just an April fool's day joke. If someone can provide a link for a mod which is similar or send instructions on how to change jool. (I am running ksp v1.12.2 with quite a few part mods and some planet mods which don't change the stock system and extremely basic knowledge in coding for ksp.) If anyone can provide help, it would be most appreciated. Thanks in advance.
  11. What should I know about planning for a Juno mission to Jool including all of the same gravity assists that the real thing did, in terms of the launch window? I have the spacecraft itself built, and it works well (probably too much delta-V...)
  12. Veteran forumites may recall when my thread "Sights of Kidonia" was active. I managed to get a humongous mothership assembled in orbit for the Ultimate Jool-5 Challenge, filled with all manner of fun payloads and equipped with over 9000 m/s of delta-V, and then... I abandoned the project, the challenge left unmet once again. That was actually my third attempt to pull it off, the successor to "Julia" and an unnamed predecessor mothership. Each attempt had been grander than the last, and each attempt had failed (for the first, I was woefully short on delta-V; for the second, a KSP update to make the LV-N nuclear engine not consume oxidizer made the existing design unworkable; and for the third, I simply stopped playing KSP for over a year and didn't feel like trying to pick up where I left off, largely due once again to changes in the game). Only one thing to do: Try a FOURTH TIME! Officially at least. I did an undocumented minimal test run a while ago with an uncrewed ion probe just to reassure myself there was hope. And naturally I must continue the trend of making every new mothership dwarf all the previous ones... Teaser image showing the scale of the hull I designed alongside Kidonia. I'll be updating the thread as important milestones in the mission are reached.

  15. Pretty much as title. I'm designing a mission to Jool (my first time visiting that particular system despite having played for more than 2 years ) and I'm not exactly sure how much dV I should equip my probe with to be able to fly by each moon. I've consulted a dV map and have gathered that I'll need about 2km/s for the transfer, but it doesn't really tell me what I need for moving around the Jool system itself. Help would be appreciated (also, side question: the dV map tells me that I need ~3.3km/s to land a probe on Tylo from a flyby trajectory. Is this accurate or will I need more?)
  16. DOWNLOAD: On KerbalX - Jool Mix-Up On Steam - Jool Mix-Up IN SHORT: This mission/challenge is all about navigating the Jool system with only the level of control afforded when you are out of comms range. That's right: no keyboard aiming, no maneuver nodes, no fine-tuned thrust. Pol and Bop won't be too much trouble. Vall could be a challenge. Tylo might be just too much for you. And what about Laythe? Seriously? I you expect me to fly a plane with the "radial out" button? Yes. Yes I do. BRIEFING: This is a PR nightmare! Jeb landed the Bop lander on Pol, the Vall lander on Bop, the Tylo lander on Vall, and the Laythe lander on Tylo! And he didn't realize it until he was getting ready to land the Pol lander on Laythe! You have to fix this. You're our only hope. Oh, and none of the landers have full control, so you'll have to do it blind. Oh, and the only lander we have ANY control of at all is the Bop lander. You won't be able to control any other lander until you're close enough to it and landed. Good luck! MODS: No required mods, but I highly recommend a time warp mod and Kerbal Alarm Clock. Don't use MechJeb or anything else that helps you control the ship, as this mission is all about having very little control. I would suggest not even installing Kerbal Engineer so you don't even know things like how far off the ground you are. DISCLAIMER While I'm not sure what will happen when you either don't win or try to trick it, but if you just play it you'll be fine. If odd things happen, let me know either here or via PM. Also, I'm still learning this whole Mission thing so bear that in mind. THE REST: I got this idea when I lost my relay to an unfortunate encounter with Tylo, and I wanted to say I'd landed on Bop. The only ship I had that could do it was on Pol and didn't have comms. I've beaten this mission in its current state. I learned a lot about controlling the uncontrollable, and hope you will too. I also hope you will find it as fun as I did.
  17. For example, I want to fly to the Jool, land and take off from Laythe, Tylo, Vall, and Bop and back to the Kerbin. How much dV do I need?
  18. How do I plan a gravity assist using Kerbin similarly to how Juno used Earth to get to Jupiter?
  19. This is how not to make a planned rocket, almost missed fuel! https://discord.gg/EJmz3kE
  20. Getting back into KSP, I wanted to finish up my video series on my Tylo Rescue mission that started in 2017...of when I stranded Bill in 2014. Sorry, it's been a few years since the last update. Hope to finish the series within a couple of months. This started as a standard Mission Report, but after reading Kuzzter's wonderful Kerbfleet stories, I've been inspired to make it more of a narrative cinematic. So forgive the inclusion of the KSP GUI when it pops up. Note: This beta 0.235 game predates Bill, Bob and Jeb having dedicated roles as Engineer, Scientist and Pilot. So they may seem a bit "out of character." The 3 year old thread on this rescue mission.
  21. Hello all, it's been almost forever and several updates to KSP since I last posted a mission report thread... Here is my entry into the Jool 5 Challenge, Jeb's Level: Episode 1 is here: The craft file is here: The mothership was inspired by this photo: Mass on the pad: 3 014.78 tons Cost: 1 825 046.0 (on the pad, no refuelling missions... yet) Parts on the pad: 410 Crew Capacity: 33 Crew on Mission: 2 of 6 Snacks/not Snacks on board: Loads...
  22. I'm going to build a reusable ship to go to Jool and back, that has to have the ability to reenter LKO. My current design I'm working on has about 10,000 m/s and I'm wondering if that's enough for the mission it'll have to undertake.
  23. The thing is this: I originally created a ship to "imitate" the Cassini-Huygens, the section that would land on Laythe I separated it successfully, I was about to enter Laythe but it just touched the atmosphere and went off to Jool. Nor did he fall into the latter but accelerated a lot. The discussion is, is this normal? I have not been able to calculate to what percentage of the speed of light this speed corresponds; Here an image.
