  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. - @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! - @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. Low Mass - @EvermoreAlpaca Video here. Mass of 6.2 tons (Current Record!). 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. 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. 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. 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! 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.

  3. 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...)
  4. 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.

  7. 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?)
  8. 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.
  9. 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?
  10. How do I plan a gravity assist using Kerbin similarly to how Juno used Earth to get to Jupiter?
  11. This is how not to make a planned rocket, almost missed fuel! https://discord.gg/EJmz3kE
  12. 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.
  13. 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...
  14. 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.
  15. 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.
  16. Even though I have 15,000 excess science.. it's not enough. I found I had not yet landed on any of the Jool moons. Bad Kerbals! So, i decided I would take a lab with me, and make a single lander that can hit all the moons except Laythe (requires a specialized design). Tylo being the biggest challenge, because of its very high gravity/size, it's like landing on Kerbin without an atmosphere. So I designed a lander with some jettisonable fuel, with the idea I would go to Tylo FIRST, and then wouldn't need those tanks for Vall, Pol, or Bop. I would bring my lab with me as an undockable section, with its own fuel, RCS, etc. Unfortunately, I forgot to put a probe controller on it, but that's OK, I'll just have the lander always dock to it. The small docking ports are for refueling (note that I can't refuel the lander without the lab until I jettison the tanks, but might have been nice to put one on an external tank just in case.). The lab acts as the big com relay back to Kerbin, if needed. And, of course, I need to refuel constantly, so I made a one-piece driller/ISRU/fuel transport, with a small docking port for refueling the lander/lab sections. Small engine to just handle interplanetary and landing on Pol. Checking out the dV for the lander, the DV maps *say* I need about 2280 to land and take off at Tylo, with 4750, I *should* have enough, right? (more on this later). It may take a low starting orbit, but on paper, it should work. So, first we get up into Kerbin orbit, and head to Minmus to refuel everybody for the long drive to Jool. Note that I was able to keep the lower booster from Kerbin, so it took two refueling runs, but the landing section would come into Jool with plenty of fuel, while the driller would come into Jool orbit with maybe only 800 dV, probably enough to get to Pol on its own, but this added extra insurance. Turns out I had plenty, transfer, orbit and landing is maybe 500-700. We refuel everyone at Pol, and head to Tylo. Now, I begin to worry- if I start my landing low (say 17km), and get back to a low orbit, can my fuel ship dip down that low to refuel (before landing and after re-orbit), and climb back out the gravity well and get back to Pol and land? The answer, it turns out, is yes. I leave about 1000 dV for each run back to Pol. So, we try our first descent from 17km. We learn two things. (1) You can't start from 17km because you can't slow down fast enough before gravity sucks you into a mountain. If you thrust downward enough, you use too much fuel. So we raise the descent to about 30km. That works well, but we land with only about 2100 dV left, not nearly enough to get back into orbit. It turns out it takes about 2500 dV to get to a roughly 10km orbit. Yep, this looks bad. So, after failed attempts, I realize I need help. So I built another fuel/engine "top" component to provide more fuel (and the thrust to counter its extra weight). Note that I added a decoupler to the docking ring, because those BIG docking rings have enough magnetic attraction they don't come loose easily. I am still granted the proper dV, but I didn't want to have something that might crash on top of me and explode after landing. With this component and some careful piloting, I'm able to land with about 2561 dV left. Note that I hit hard when I landed and broke a strut, but I should still be fine for Vall. 2561 was enough to put us back into a 9kmx20km orbit, with enough dV left to re-dock with the science section. Then the refueler only had to make one stop! So, the major lesson learned is- don't trust the dV maps. It took about 2600-2800 dV to land and 2300-2400 to reach stable orbit, and that's with optimal piloting. But other than that, the "two ships, single lander for four moons" project is so far a success, and has passed the toughest test.... Tylo, with only one landing strut as a casualty.
  17. Welcome! So, you want to go to Tylo. Alright, keep reading then. But know this: Tylo WILL BREAK YOU. Why? It's as big as Kerbin, just a little bit lower surface gravity, but HAS NO atmosphere. That means you will have to brake ALLLLLL the way down to the surface burning precious fuel. You will find yourself orbiting very low (10km or so) with speeds of 2400 m/s, and if your TWR is lower than 1 you will fail. Simply. This is not a tutorial, this will not teach you how to do transfers between planets, nor how to construct a rocket. It will just tell you what to expect before arriving there. Ok, here we go: What you need: Basics - Since it's a manned mission, you need at least a scientist, to reset the science stuff and collect more. A pilot and engineer are optional, if you have a good relay network, that is. - About 19000 Dv total, to ensure you don't get stranded in space. My rocket had 19500 and ended at Kerbin with 1000 left, but I used some gravity assists in the middle to economize fuel. -Nuclear engines. Highly recommended for space. NOT FOR LANDING - Some landing engine with good thrust. NOT FOR SPACE FARING. What you need: Specifics - A rover: Tylo might be treacherous, but provide a very good ground for rovers! It's fun, actually. It will behalve almost like in Kerbin. Beware of speeds surpasing 40 m/s! -A lander: DO.NOT.MAKE.YOUR.LANDER.TOO.VERTICAL (like i did) or it will fall!!! I made a ship bottle shaped and it was a pain in the ass to land. My horizontal speed was between 1 and 2 m/s and that was enough for it to tilt to one side when touching ground. A wide-base lander would have been much better suited. -An escape ship: Once the fun is over, you need to return. Calculate about 3300 Dv to get to orbit from Tylo's surface, to hopefully your mothership, space taxi or whatever is waiting to deliver bak home. What to have in mind: -Bring lots of solar panels or isotopes, Kerbol shines too softly on Tylo to gather enough energy. -Big wheels on the rover wont hurt. -Save before landing. Even close to the ground your engines will fire uncontrolably at full force, aproach as slowly as possible, and reduce your gimbal. Consider Tylo as a super Mun. -Use Jool, Laythe or even Tylo to assist your interplanetary brake. Actually, every Jool mission should make use of its satellites to help you. -Too insecure to try a Tylo mission? Go to Pol first, it's close by but much simpler to land (surface gravity a noch more than Gilly) Have Fun! (manned mission to Pol, SOON!)
  18. The buoyant force works not only from the liquids, but also from the gases. So how possible is to build bases on the level of gases with density equal density of the base? The density of atmosphere at the sea level on the Earth and on the Kerbin ~ 1.25 kg/m3 . So if we need to reach the density level like water, we need to reach the depth when pressure is equal 800 atm. What do you think about this? I think that it's impossible, because pressure must be 80000000 kPa, but the pressure limit for all details is only 4000 kPa. And also it would be impossible to take off from this depth because pressure is unbelievable and I think that the atmosphere altitude would be about 1-3M KM. P.S. That was written by Russian student that study in 8 class. Maybe I don't know some physics laws.
  19. A proposal was made to design a long-ranged interplanetary transport based on the venerable Julius platform. The A3-Julius was a military cargo transport (often nicknamed the Space Truck) used extensively during the Minmus-Mun Conflict. Even though the ship was unarmed, it's oversized manoeuvring pods gave it the thrust needed to side-slip in all directions. Thus, it could perform evasive manoeuvres needed to avoid enemy attacks. This, coupled with it's thick plating, gave it a reputation for reliability and survivability (albeit at the cost of delta V). fig 1: A3-Julius military transport The new ship will be named Jericho, and it's mission is to send a crew of four into the outer solar system. Prior missions have proven unsuccessful, as the attempted in-situ resource utilization ended in failure. Insufficient fuel for a return trip as well as a lack of vital resources resulting in a loss of life of all crew members. To correct these oversights, the Julius-class will feature a state of the art ore scanner, capable of pinpointing viable ore deposits from a distance of over 600 km. High-ISP nuclear engines will serve as the main propulsion systems, with lower-efficiency, higher thrust engines providing extra thrust when needed. Nuclear power will also be used to provide electricity in the sun-starved depths of the outer system. The ship will also feature an entirely self-contained mining and refinery system capable of refuelling it's tanks in under 2 weeks. This equipment will significantly dig into the ship's mass-budget, and as such multiple refuellings will be necessary to reach Jool. First at Minmus (where the ship will perform it's initial shakedown and extensive system's tests), then Dres, until finally refuelling at Pol when it arrives within the Jool system. While there, we expect to perform the first ever manned landing of Laythe. The lander (then unmanned) will be sent ahead of the Jericho and rendez-vous with it later. The ship's ventral engines provide an acceleration of 0.12 g with fuel and ore tanks at full capacity. At reduced capacity the engines can achieve 0.20 g, meaning it could theoretically perform a ventral landing on the Mun (though his has yet to be tested, as it would be pushing the safety margins to their limit). fig 2: the Jericho undergoing final tests before being mated to it's launch vehicle Since the orbital shipyards have yet to be repaired following the end of the war, the ship needed to be constructed on the ground, and then hauled into orbit on boosters. After careful planning, a modified Boreal-class lift vehicle was successful at performing the boost. The Boreal booster is capable of providing more than 13 million newtons of thrust at liftoff. Even this was not sufficient to lift the Julius, so modifications were made, adding 4 vector engines as well as 8 solid rocket engines to the first stage. fig 3: a Boreal-class booster in it's cradle prior to modifications fig 4: the Jericho escaping the atmosphere The vehicle boost was meant to be unmanned (due to the extreme G-forces that the vehicle would experience on ascent), Jeb insisted on coming along for the ride. The rest of the crew boarded via shuttle-capsules. Boarding was finished last night at 21:00 hours KCT. The ship is now ready to depart on your order. The injection burn will require around 1400 m/s. Upon departure the ship will be carrying a total of 4000 m/s (a significant excess and safety margin). God speed, and good luck. fig 5: the mission begins (( If the delta-V costs seem a bit high, it's because I'm playing on an up-scaled Kerbol system. Everything is 2.5x bigger than normal, resulting in some pretty big delta-V requirements. ))
  20. This day, i launched the rocket that carried the JoolianExplorer, a probe that will explore Jool and his moons. I don't have the screenshots to show cause i'am playing in a another computer. Forget this, let's get started. The rocket was ready to launch, but a new foe has appeared. Who? THE SAS!!!!! aww man.. Again the SAS came with his incredible "crazy" out of control attack. I tried but at least i recovered control. Now entering LKO and prepare to half-burn. Half-burn complete, now manuever to solar orbit and injection burn to Jool. Years later, periapsis at 459K (idk), burning capture orbit. Acheived LJO (Low Jool Orbit). Window transfer encounter to Laythe. Burning to Laythe, capture orbit and done... And some juicy science. That's all i have got from today. I was planning to launch a probe to Jool today to explore even the moons. I orbited Laythe cause i was needing to put some waypoints to my vessels land on a good place that isn't a giant sea. Laythe. A Kerbal beautiness.
  21. NOTE: if you want rings for all the planets, not just Jool, check out the KSP Ringification Mod. Tired of boring old Jool? Add some rings to it! This mod offers six different ring variants, in a range of styles, sizes and colours to suit (almost) everyone! Jupiter style - Grey and relatively faint, with one bright white ring. Based off of the real-life rings of Jupiter. Saturn style - Various shades of green and yellow, with seven distinct zones. Also includes a faint Phoebe ring beyond Tylo's orbit - see if you can spot it! Uranus style - Slim and grey, stretching out towards Tylo. Fainter and less "in yo face" than Saturn style, but more extensive than the Jupiter style. Neptune style - faint and blue. See if you can find them all! J1407b style - yellow and mind-bogglingly massive. X style - who says crossed rings aren't possible? Top tip: you can add rings to Neidon (in the Outer Planets Mod) by going into the config file, changing "Jool" to "Neidon", and changing "AFTER[Kopernicus]" to "AFTER[OPM]". Pictures: J1407b style rings J1407b style from KSC launch pad X style rings Neptune style (around Neidon) More pictures coming soon! Can be downloaded from Spacedock. Make sure you have the correct version of Kopernicus installed! This mod is released under an MIT license.
  22. The time has come for Kerbal-kind to leave our small blue oasis on Kerbin and venture out into the great beyond - to the unknown worlds that beckon us from afar like silent lanterns adrift in the night. We are resolved to go to Jool! To unlock the secrets of the unknown, and hopefully also to come back! Prologue: What follows is my account of the planning, execution and aftermath of the Magellan mission to the Jool system in my career save. I have spend the majority of my time playing KSP within the Kerbin system visiting the Mun and Minmus ad nauseum, and unlocking most of the tech tree. Besides Duna, I have never visited any other body in a career save. My goal in this career is to send missions to visit all the celestial bodies in the Kerbol system. Some will be manned and some unmanned. With a Jool transfer window approaching in 41 days, I have decided to take a bold step towards this goal by sending a crew of valiant (or maybe daft) kerbals to this giant green world and her moons. Magellan Mission The Magellan mission will take after the great explorer Ferdinand Magellan in attempting a feat which has never before been done (by me). To send a manned mission to the Jool system, take science data on all the worlds therein and return to Kerbin. I'm calling this a Jool-4.5 mission because unlike the Jool-5 mission reports from challenges, there will be no flags or footprints on Tylo, instead I will have a probe land and report back with science data. But the rest of the moons will be visited by Kerbals. Here is the mission patch for the Magellan Mission : The patch shows the silhouettes of Jool, Laythe, Val and Tylo against a backdrop of stars and backlit by the sun as the spacecraft flies by. It is modeled after the STS-41 mission patch. The motto is latin for "To the stars through adversity", and was totally Magellan's rallying cry on his voyage something I thought sounded cool. This mission report is primarily for my own benefit, as something to look back on when this mission is over, but I hope others will find it enjoyable as well. I intend to chronicle my thinking as it relates to mission planning, vehicle design and testing and mission execution in a matter of fact way, and not to write a story or a novel. Right now, I'm not planning to do much if any roleplaying from a Kerbal standpoint, but who know maybe I will get carried away later on. Notes about my playstyle: At this stage, I have designed the vehicle and a rough sketch of the mission plan. I build and test all my vehicles in a sandbox save and then copy the craft files to my career save. For testing purposes, I am allowing myself cheats to get the vehicle into LKO, but no testing will be done in the Jool system. This will hopefully force me to think more carefully about what conditions I will encounter at Jool and will preserve the newness of the experience for me when I actually fly the mission in my career save. I do use quite a few mods, but no part mods (aside from SCANSAT). The mods that I use fall under one of three categories: (1) Visual enhancements (2) Sounds/Effects to increase immersion and (3) Gameplay tools (ie KER) What's Next: In the next posts I will be showcasing the design of the spacecraft, and possibly doing some on-orbit testing. Once I unlock all the parts I need in my career save we will get onto the meat of the mission.
  23. Simple poll: Would you like to see another gas planet besides Jool? If so describe the moon(s) you would want in the GP2 system. FYI : I plan to do a poll almost once a month because of how popular (kinda) this was. Hint for next poll (minimally encoded, I'm not THAT nice): Wait, wait, check my other new poll now:
