  1. the fact that you have liquid methane means you have mods, and we can't help without knowing more details. why can'ìt you make liquid methane? what kind of stuff has your ship? too many unknowables
  2. i can't help you with that, i don't know coding. all i can say is that i had the same problem and i could still make it work you said time warp does not fix, but how long did you time warped? just entering time warp didn't fix for me either; it generally went in periods, a few in-game days with the bug, then a few in-game days when the drills would work normally. but it may well be possible your issue is different, though similar, to mine.
  3. it's a bug that happens sometimes with kerbalism. all my long term missions with kerbalism suffer from it. the good news, though, is that it's temporary. time warp, and after a while the drill will detect ground contact again. and then it will stop detecting ground contact, and then find it again... all in all, mining resources is slower than it should be, but it works.
  4. Part 2: Probing the way forward I don't have enough deltaV to land a crew on Mun, and I don't have enough life support to send a crew on Minmus. This chapter involves lots of probes. I got a relay network, and permanent science stations on Mun and Minmus 2.1) If you believe, they put a probe on the Mun 2.2) Jeb review-bombed this flying hotel 2.3) Networking! 2.4) Caveman hungry! Caveman goes to mint ice cream moon!
  5. the transfer maneuver tool is garbage. you are much better off learning interplanetary travel and planning the maneuvers for yourself.
  6. Part 1: Escape from Kerbin The limitations of life support make Mun missions a lot harder, and Minmus missions impossible early on. To leave Kerbin I need to research basic science; can I find the necessary science points without leaving the home planet? 1.1) Strip-mining Kerbin 1.2) We choose to go to the Mun, even though we're not ready for it Aftermath In the end, all this science farming - getting all Kerbin biomes, and all science from Mun space - barely got me the 45 science required for basic science. The tech tree, after this chapter It was close, though not exceedingly so. If needed, I still could gather flying low EVA reports around Kerbin, which I forgot; that was worth 3 to 5 more points. Then I could collect goo observations multiple times, getting an additional 0.1 points per biome. On all KSC minibiomes, that amounts to something. Plus, I missed Mun space high thermometer science, because in that second flyby the thermometer exploded on reentry. All in all, I could have gathered 6 to 8 more science points that way. Then, if I really was desperate, there are some ponds around where one can get splashed down science in grasslands and desert biomes. But I'd have to be really desperate to try to target one of those tiny ponds while falling down from orbit. So yes, it was remarkably close. I needed 100 science to unlock this part of the tech tree - which is the bare minimum to achieve Mun landings - and even the most efficient farming would have given at most 10% more than that. Just goes to highlight how impossible it was to try this challenge with kerbalism reworked science.
  7. Not sure if this thread is still active, but I'm doing a nanodiamond + kerbalism challenge. I plan to end with a duna mission eventually
  8. My previous caveman run relied heavily on being able to stay in space indefinitely. Doing rendez-vous without maneuver nodes has that effect. Kerbalism puts a sharp time limit on how long i can stay in orbit. it also requires bringing more parts and more mass for life support, when both are heavily limited by the caveman challenge. A couple weeks ago I started toying with concepts for a kerbalism nanodiamond challenge; now it's time to start a new report. To think I announced my retirement from this game only a couple months ago... Part 0: Thou shalt not get basic science! At first, I try the challenge with full kerbalism rules. But it turns out, kerbalism deeply nerfs early game science; with rewards capped at 10%, it is impossible to leave Kerbin. And that's before even counting all the issues with life support and electricity I therefore settle for using kerbalism, but keeping stock science.
  9. it doesn't matter how safe your rover is. never let more than 15-20 minutes pass between saves. something i learned through painful experience. the problem is, if your rover is safe and sturdy, you'll just go faster. you'll keep going faster until you wreck it. it's called risk compensation. 'Booth's rule #2' states that "The safer skydiving gear becomes, the more chances skydivers will take, in order to keep the fatality rate constant", and it clearly applies also to driving rovers.
  10. well, the game was only spawning test and tourism contracts. for some reason, recovering a vehicle was not paying back the command module, so testing at the launchpad for pennies was actually performed at a loss; but contracts to test parts splashed down culd be done easily, and thye paid some 1500 to 2000 funds - meaning a net gain of 1000 per such test, after removing the cost of the crew pod. that was my source of money - though, that being a test run, i actually cheated my money, as before spending weeks farming boring contracts i wanted first to see if the challenge was possible at all. those contracts didn't pay reputation. I needed a minimum reputation treshold before i could activate the [money to science] policy. but tourist contracts did pay a reputation point. they were a financial loss, though. a two-seater needed to bring a tourist in a suborbital jump would cost around 10k, almost none recoverable, and the tourist would only pay around 1000. but it would give a reputation point. i needed some 400 more reputation to reach the point where i could unlock the administrative policy. let's keep round numbers for the sake of calculation, and assume i would be able to pay a tourist contract for every 10 test contracts. in this case, i would have needed to conduct 4000 test missions, and carry 400 tourists, and then i could unlock the policy. it would give 1 science every 12000 funds, iirc, which means (if it even does give 0.1 points every time I run a test contract, rather than rounding down to 0 for values too small), that i'd have needed some 400 more missions to unlock basic science - which would give both the stayputnik probe core, and the first real source of electricity by unlocking extra batteries. i'd also needed several dozen missions to biome farm all of kerbin. they would entail launching an orbiter 2 (it arrives orbit with 1100 m/s, which can be used to kill orbital velocity fast and drop with fairly good precision. even then, small biomes like badlands and tundra would be hard to pinpoint). each such orbiter would then require 11 test missions to farm money. or, i could have just farmed more science once i unlocked the policy. hey, now that i break it down that way, 5000 missions seem relatively feasible. they are short ones, probably can be done in 5 minutes (more for suborbital tourists, but test contracts in the sea are fast), so we're looking at 100 hours. more or less what it took for the orbital assembly of navis sideralis neanderthalensis. but so extremely boring, falling into the sea 4500 times. once i unlocked basic science, i could start getting more science from unmanned mun and minmus flybys. that would give enough for general rocketry, which would unlock "test the terrier engine" contracts. with probe cores and terrier engines, i could land unmanned probes on mun and minmus, farming enough science to unlock solar panels and docking ports. once i got solar panels and docking ports, i could start building bigger ships one module at a time, and i would have no limits. i was actually planning to end the run with a duna mission; with what i learned of manually calculating orbital times in the previous jool run, it would be feasible. or, i could have just kept on gaining science by money.
  11. where? because i am looking at tha cfg file and i don't see it i see only one mention of science, and it only says about storage, transmission and analysis. that is, it would have the science experiments happen instantly instead of over time, and it would have the normal stock way of handling science experiment instead of the division between samples and data. oh, and there's sciencedialog, but it applies to dialog. i don't see anything that would leave all science management as stock. not unless some of those options are mislabeled
  12. I read somewhere that there is a simple option to install kerbalism while keeping the normal stock science. in particular, i am trying to make a kerbalism run with science capped at 10%, but i'm finding it impossible, with the goo container nerfed and the ksc minibiomes removed, to get away from kerbin orbit. can anyone tell me where to edit the config files to restore normal stock science? thanks
  13. I tried a kerbalism nanodiamond caveman run. i failed. not (much) because of the additional limitations of life support, but due to kerbalism science rework. kerbalism did - remove all the ksc mini-biomes that gave a much-needed science boost to nanodiamond caveman challenges. - made goo a global experiment; you can only run it once per planet, instead of once per biome. goodbye to another big chunk of early science - flying low crew report has become global; you can only collect it once, instead of once per biome over all kerbin. - space low eva report is also global, no longer biome dependent. as partial compensation: - flying low baromether is biome-dependent - you get a new instrument, the geiger counter. - probe cores have a handful of specific experiments Still, I gave it a try. Getting the easy experiments (goo and reports from early flights around the ksc) doesn't even net enough science to unlock the first node. I could get there by biome-mining, but that's time consuming, so I took a test contract to get early access to decoupler, and built a suborbital jumper with nothing but flea boosters the flea-based suborbital jumper And an improved version, that can get to high space. barely with that, i brought home enough science to unlock engineering 101, which includes the thermometer and geiger counter. the thermometer is a welcome, if limited, addition to the science options. the geiger counter... it gives exactly 0.1 science points for every kerbin biome. plus 0.8 total for crossing both radiation belts. Still, with that and a few biomes I got basic rocketry, which gives access to the first orbiter. The main reason to unlock the first orbiter is that the contract pays 1 science Then I went squeezing every possible bit of early science I could this contraption managed to bring Val in low orbit, to collect an eva report. worth 1 full science point! This improved version could get to space high, for 1.5 science points! Alas, t's not enough. I collected all science I can get from kerbin orbit, and while I still have to mine kerbin biomes, each one only gives 0.8 science (0.2 for thermometer flying low, 0.1 for crew report, 0.1 for radiation scan, 0.1 for thermometer, 0.3 for eva report. remember, neither flying low report, flying low EVA nor goo canisters are available in individual biomes). I run all the math, and determined that if I stripped all kerbin biomes, I would get to 13 science. not enough to unlock survivability. So i tried a Mun flyby. It's potentially possible. this thing, on a lucky day, can get to orbit with 1100 m/s left can I return from Mun without maneuver nodes, without quickloading, and with only 250 m/s? I didn't have a chance to try. After a couple hours, I got a message that Jeb was dieing. You see, with kerbalism life support kerbal breath, and they produce CO2. That has to be scrubbed, but the scrubber consumes electricity. the battery lasts approximately 1 hour, then the CO2 is no longer removed. It accumulates for another hour or so, until it reaches 2%. then the kerbal starts to suffocate. so yes, eventually it was life support that killed me. so, I can't go to mun without a source of electricity. the engine produces electricity, of course, but i don't have enough fuel. Kerbalism give me access to monopropellant fuel cells, though, incorporated in the crew pod. i tried it, and one hour later jeb suffocated. turn out, that fuel cell consumes oxygen, and pretty fast (the crew pod has enough for 5 days under normal use). and I haven't unlocked extra oxygen tanks yet. but ok, i only need to find a couple science points somewhere, and then i can unlock oxygen tanks and use the monopropellant fuel cell and reach mun. alas, what put the final nail into the coffin was discovering that the 10 units of monopropellant included in the crew pod only generate a dozen units of electricity. it only gains a few minutes of life support. and I can't put any extra monopropellant, because - you guess - i haven't unlocked mono propellant tank. even if I could launch two crew pods together and still somehow have enough deltaV, life support is still insufficient to reach mun. I'd need to unlock basic science to get the first real source of electricity. it takes 45 science. and while survivability unlocks the barometer, that gives 15, maybe 20 science points from flying around kerbin. and it doesn't work in space. i'd have no way to get the remaining 25 science. so, pure kerbalism nanodiamond can't be done. Ok, technically i could fulfill tourist contract until i improve reputation a bit, which would allow the private science contractors policy, that would give science every time i earn money. but that would take an ungodly amount of time and, more importantly, it would make the challenge meaningless. now i'm trying to figure out how to keep kerbalism life support and radiations while keeping the normal stock science, and try with that.
  14. Congratulations on completing the Jool 5 challenge in a heavily modded environment. before i register your submission, a few additional questions: - what was the part count on hephestus V? did it lag significantly for it? - how did you tackle life support? did you just bring a large amount of supplies, or was there some more complex recycling chain involved? P.S. Sorry for not being impressed by the 1000 tons and 45 nervs, but I've done a lot worse. A downside of picking me as challenge keeper. P.P.S. congratulations also on being the first submission I review as new challenge keeper
  15. I opened the new thread. Are there any pending submissions that were missed?
  16. This challenge was continued with permission from the previous thread manager @JacobJHC LINK to the old Jool-5 thread There are over 50 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 over forty-five pages of entries and discussion, so look and see what made it and what didn't LINK to the oldest 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. - @Superfluous J V ideos here. Used a single launch to send three Kerbals to the Jool system, where the ship parked in an elliptical Tylo orbit. From there a tug took the landers to their respective moons where they *wait for it* landed. The ship then fired all three Kerbals home safely. An amazing mission and equally amazing videos. - @Xurkitree Grand Tour Thread here. A surprisingly small mission that not only landed on all the Jool moons, but also every other planet and moon in the system. The mission sent a craft out to Eeloo, which landed and returned to Jool before heading home. Once in orbit Derton was picked up by a recovery rocket and landed safely back on Kerbin. Outstanding. ISRU Video here. I don't even know where to start, Xurkitree didn't just do a Jool 5 in this mission, they did it twice. A large SSTO ISRU craft launched and refueled on Minmus before gravity assisting its way to Jool where it completed the landings and then returned to Kerbin, WHERE IT RELAUNCHED and then detached a small non-ISRU craft which carried out the landings again. A fun note was when the Laythe lander landed by computer control while the Kerbal parachuted down. Great job on your fourth Jool 5 submission! - @dvader Album here. A single launch using only chemical engines. Used several gravity assists to make the trip to Jool cheaper in terms of delta-v. Used a small but capable plane for Laythe, and a donut lander for the other moons (with extra fuel for Tylo and Vall.) Overall a very optimized mission, complete with a near KSC landing. - @fulgur Album here. A very small and well optimized mission with a smaller-than-you'd-expect mothership. Ions were used to scoot Jeb and Vall about the system to the various moons, and then left as the small mothership made its way home, getting into Kerbin orbit with only forty m/s of delta-v remaining. (Talk about close margins!) The crew were returned safely by an Aether SSTO. - @Pro100kerbonaut ISRU Mission report here. Used an SSTO spaceplane to go to Minmus to refuel, then flew off to Jool. This mission is the most impressive in how it handled the Tylo landing. Not only was the landing done using the SSTO, but it came directly from Vall without refueling at Bop or Pol. The landings were all completed flawlessly, but was destroyed in a crash landing back on Kerbin. The pilot survived though, and any landing you can walk away from... - @dnbattley Album here. A direct ascent mission to all five moons, starting with Pol and Bop, then Vall, Tylo, and finally Laythe. The tensions on this mission were very high, as Jeb began his Tylo descent on a NERVA powered craft with a TWR of .9, managing to get it above 1 just in time to pull off the landing. From there Jeb flew to Laythe where he somehow missed the ocean (this might be a KSP first) and used the craft's jets to push it into the water for an ocean launch. After struggling back into orbit, Jeb flew by Tylo back to Kerbin, using a Duna aerogravity assist to get the right trajectory (ARE YOU SERIOUS?) Upon returning to Kerbin he was able to sneak in a Minmus landing. This mission is without a doubt one of the more Kerbal ones submitted, complete with Jeb gliding the final stage down to Kerbin with his EVA chute. - @EveMaster Grand Tour, ISRU Thread here. Additional album here. EveMaster managed to complete the Jool 5 challenge with an ISRU craft, utilizing the power of two mammoth engines and a detachable spaceplane. Also went the extra few million miles and completed a grand tour! Both Bob and Jeb were on this mission, however Bill stayed behind on Eve, so only Jeb is being considered for this entry. Regardless, an excellently executed mission. - @ManEatingApe, @Jacke, @dvader, @Muetdhiver, @Rakaydos, and @Pds314 Mission thread here. What these users have completed is the first community Jool 5 mission for this specific thread, possibly the first ever. Furthermore, this mission was done in a 'caveman' style approach, meaning no maneuver nodes, tier one buildings, and launch mass restrictions. These restraints meant the main ship was built over multiple launches. The landings were carried out by a plane and three identical landers, which carried Jeb to, around, and back to Kerbin from the Jool system with excruciating precision. I highly suggest checking out this mission's thread, it's one of a kind! - @Space Nerd Album here. Using a long nuclear mothership, Jeb and Malvis conquered the Jool system in a surprisingly easy manner. An off-center Bop/Pol lander was docked onto the side of the mothership, leading to one of the more interesting mothership designs. Jeb took Laythe, Tylo, and Vall, and Malvis handled Bop and Pol. Once all the landings were done, they flew back to Kerbin and used a 10 meter heat shield to slow down and splashed into the ocean. - @ralanboyle Video here. Using a single brute force launch, a main station of sorts was put into Jool orbit,. From there a Laythe-plane was released, and upon returning from Laythe, a lander/fuel tank combo (and an extra part for Tylo) took on Tylo, then Vall, then Bop, then Pol. They forgot to put a flag on Pol, but who cares. Also, the lander was able to return to Kerbin all by itself. Quite the capable craft I'd say. The mission is edited into a very nice video, and I suggest giving it a watch if you've got the time. - @Carbonjvd Album here. Using the incredibly stylish IPV Excelsior spacecraft, Tridous Kerman flew to Minmus to refuel, where she picked up two more crew members in Minmus orbit. From there they flew to Jool, where they refueled at Bop. After the tanks were full, they hopped to Pol, then Tylo, then Bop again, then Vall. From Vall the crew hopped back to Bop for more refueling, then flew to Laythe. After converting stored ore into liquid fuel, the crew touched down on an island, then (you guessed it) flew back to Bop! (for more fuel) From this final Bop landing, the Excelsior returned to Minmus where it all began, then safely touched down on Kerbin. A stylish landing for a stylish craft. - @camacju Grand Tour. Album here. This mission is impressive as it not only visited the five moons of Jool, but also every other landable surface in the Kerbol System. The Jool portion of this mission was completed after the mothership completed the Eve portion, then used gravity assists to get to Jool. A Tylo assist put the ship on course to aerobrake at Laythe, and after landing on Laythe the lander was then reused for Tylo. The other moons were completed using a smaller lander, and the brave Kerbonaut landed back at Kerbin after quite an exciting trip. Video here. A very well edited video of a Jool 5 mission which used only liquid fuel! Launching from the runway as a spaceplane, the craft flew up before staging its rapier engines and continuing to orbit on nerva-power. The Laythe landing was done using a smaller spaceplane, and the rest of the landings were done using a very impressive lander which used only 1 nerv engine to land on all the other moons, including Tylo! The lander also served as a trip home and as a heat shield so that the brave kerbonaut could parachute to safety. This mission is beautifully summed up in the video link, and I highly suggest checking it out. A truly unique mission! Video here. Another liquid fuel only mission! This one utilized multiple relaunches of the same spaceplane to put multiple fuel tankers in orbit. From there, the craft departed for Jool after some gravity assists and once again demonstrated the unusual, difficult, and impressive use of a nerv-powered Tylo lander. The video this mission was edited into is nice and tidy as well, and I suggest watching so you can see all the work that went into it. Video here. And yet another Jool 5 mission, but this time with only one engine! A cargo spaceplane with a single rapier made multiple launches to place several fuel tankers into orbit before flying a gravity-assist-utilizing course to Jool. Once in Jool space, the Laythe landing was conducted first, and then the plane ditched its outer shell so that just the rapier engine and a few fuel tanks remained. The craft then docked to a fuel module in orbit and flew to Vall, landed, then went to Tylo where a dedicated fuel drop-tank was used with what I'll dub "backflip staging". From there the Pol and Bop landings were done, with fuel to spare. After a fiery return to Kerbin, the brave Kerbonaut, Wildard, paraglided safely into the ocean. I recommend giving this video a watch, because it's short, to the point, and an amazing display of Kerbal engineering. Grand Tour. Video here. This mission is truly a record breaker, as not only was it a Jool 5, but it is the lowest mass Grand Tour without ISRU record holder, with a take off mass of 14.447 tons, less than a Mammoth engine! To focus on the Jool 5 portion of the mission, a spaceplane made a bouncy, thrash-flippy landing, then a tiny tiny lander was used to tackle Tylo. Pol and Bop were handled by a small ion lander, and Vall was handled by a lander so small it looks like a pancake. You should definitely give this mission's video a watch, as words cannot truly describe just how insanely optimized this mission was. - @Goufalite Video here. This mission began with the assembly of a main mothership in LKO. Once complete, the ship cruised to Jool where it used gravity assists to achieve orbit. From there, the spaceplane was deployed to Laythe, but missed its target island. Never fear! The spaceplane had such high performance it was able to fly to a nearby island. Once back with the mothership, the SSTO was drained and detatched, and a capsule on its nose was undocked and docked to the Tylo lander. The Tylo lander used 2 aerospike engines to blow its way to the surface, and the final stage of the lander redocked to the mothership to be reused as the lander for Vall, Bop, and Pol. After visiting Vall and Pol, the lander flew by itself (and out of connectivity range) to Bop, where it landed and returned to Pol all on its own (Goufalite found this method was more fuel efficient). After returning to the mothership at Pol, a Tylo gravity assist sent the crew home, and both safely landed only 50 kilometers from the KSC. This mission made me nostalgic for my first Jool 5 mission, which in turn makes this mission special to me. Nice job, @Goufalite. - @king of nowhere Grand Tour. Mission thread here. This mission was done using Kerbalism, and an absolute UNIT of a mothership. Appropriately named the DREAM BIG, this ship conducted the Jool 5 challenge with dozens of farms, radiation shields, and drop ships to keep itself self-sufficient. Fighting food limitations, mod issues, solar storms, insanity and radiation damage, the crew of DREAM BIG flew throughout the entire Kerbol system planting flags on every world. The mission thread is an entertaining read, and has a video tour of the DREAM BIG spacecraft, which I highly recommend you check it out. I congratulate @king of nowhere on completing the mission, and for not losing their sanity in the process! Mission thread here. This mission was done with tremendous build constraints, and done entirely in a no-contract career mode save. Each launch was limited to 20-25 tons, meaning it took dozens of flights to finish the main ship, the Marco Polonium. The ship used many cost and weigh saving methods, including using the Laythe lander as a stage on Tylo, and by using claws instead of docking ports in some cases. The mission also visited Duna, Ike, Eeloo, Dres, and Eve (orbit) as well. This mission is one of the most entertaining ones I've reviewed (along with one of the most optimized) and I highly recommend giving it a read. Mission thread here. This mission was much like @king of nowhere's previous two in the sense that it involved Kerbalism and self-imposed building constraints. The result was a Jool 5 mission designed and flown to be as realistic as possible, and done with a maximum LKO mass of 140 tons. Bill and Bob took the Economic Downturn and its support craft to Jool and visited Tylo first, using the Seated Man lander, then made way for Laythe to deploy the Sole spaceplane, each accompanied by the space tug Right Answer. Sole's upper stage was reused as a Vall lander, while Seated Man's upper stage was used to land on Bop and Pol. For the inner three moons, great care was taken to limit the radiation damage incurred on the crew, with Bill being irradiated all the way to 95% upon his return to Economic Downturn. The return trajectory had to be tweaked a few times to prevent the capsule overheating, but Bill and Bob ultimately prevailed, and returned to Kerbin with nearly 500kg of samples. This mission is one of the few anxiety inducing submissions due to the challenges imposed by Jool's radiation belt. If you are a fan of gripping mission threads, I suggest giving this one a read. - @Lt_Duckweed Video here. This Jool 5 mission is notable for three reasons. Firstly, it is fully recoverable. Secondly, it only uses two engines, being the nerva and rapier. And thirdly, it was edited into a masterpiece of a video. This mission began with a launch just west of the KSC, and made a direct transfer to Jool. Upon Jool arrival, the elegently designed craft deployed a nerva-propelled lander, which performed the Tylo landing. After refueling at the main ship, the lander then visited Vall, Bop, and Pol with refueling trips to the main ship in between. The lander then returned to the main craft, which transfered to Laythe, completing the final landing. The craft then returned to Kerbin and came to a stop on the KSC runway, returning with it every part it launched with. I must repeat the high quality video the mission is edited into, and strongly suggest giving it a watch. - @bwest31415 Album here. This mission began with the launch of a long thin rocket which was followed by a normal transfer to Jool. Upon arrival to Jool however, inflatable heat shields were used to induce a Joolian aerobrake, a maneuver I've scarcely seen used since the addition of reentry heating to the game. The first landing to be done was Laythe, and the final stage of the lander was used to land on Vall and Tylo. The lander then left the main ship behind and traveled to Pol, then Bop, then back to Kerbin all without refueling. Jeb landed safely back on Kerbin after a toasty aerocapture, and exited the pod to take in a nice mountain view. - @18Watt ISRU, Thread here. This mission was done as both a Jool 5 and a Kerpollo submission. The mission began with a brute force launch and direct transfer to Jool. The mothership used wolfhound engines, which was good for TWR but slow when the ship was fully fueled. The ship flew first to Tylo, and after landing, the Tylo ascent stage would be reused for later landings. Next, the ship went to Bop to refuel, then to Laythe, where a staged spaceplane returned the brave Kerbonaut to the mothership. Next Val went to Vall, then the ship went to Pol and landed, before returning the crew to Kebrin, who parachuted to the surface of one of Kerbin's icecaps. - @OJT ISRU, Thread here. This mission was fully reusable* (apart from deployed fairings but we couldn't decide if that counted or not) and landed every component of the main ship back on Kerbin upon finishing the Jool system's exploration. The mission began with three launches, one for the mothership, one for the lander, and one for the SSTO spaceplane. Due to unfortunate moon placements, no gravity-assisted captures were possible and a retroburn was conducted. From there, a surprise Laythe aerocapture was conducted, saving much needed fuel. After the Laythe landing, the main ship flew to Vall, left the plane in orbit, and then landed with the lander beneath it and refueled on the surface. Next up was a Tylo landing with razor thin fuel margins, followed by Pol and Bop. It is worth noting that this mission did not repeat OJT's previous Jool 5 mission's Pol refueling process, in which the lander did numerous trips to the surface to bring tiny bits of fuel up to the main ship. With the landings complete and plenty of fuel to spare, the ship flew back to Kerbin where it landed piece by piece, with the lander being launched an SSTO parachute module. An excellent mission, and no doubt a fine achievement. - @kspfreak Video here. This mission not only visited the moons of Jool, Bop's Kraken, and in a rather small vehicle, but also visited every other moon in the entire Kerbol System! This mission's video is a fun watch, and ends with a fun paraglide back to the KSC. A mini grand tour of sorts, and very well done. - @JeDoesStuff ISRU, Video here. An SSTO submission! Coming in with a mass at just under 30 tons, JeDoesStuff showed off an incredibly refined ISRU SSTO by flaunting it around the Jool System. Included on the spaceplane are subtle but clever features to aid in launching horizontally, such as Vernier thrusters on the nose to raise attitude during takeoff, as well as a large landing gear that is only deployed to angle the craft. I haven't seen the latter of those additions on an SSTO before, so I applaud the ingenuity! The video this submission is contained within is also very well edited, resulting in a brief, yet concise viewing experience. If you're looking for a fun video to watch, or to see a razor-thin-margin Tylo landing, then this submission is for you. Low Mass - @EvermoreAlpaca Video here. Mass of 6.2 tons. Spaceplane launch, gravity assists off Kerbin and Eve to reach Jool. Landed on Laythe with the same rapier used in the launch stage, returned to orbit with an incredible TWR, scooted over to Tylo where the most bare-bones Tylo lander I've ever seen was used to land on and take off from Tylo (saved fuel by having Bill push it to the top of the mountain), flew over to Vall where the landing was done using staged batteries and a single ion engine. The Vall lander (which was also part of the Laythe lander) completed the last two landings on Bop and Pol and returned to Kerbin using many more gravity assists before preforming an aerobraking, with Bill parachuting to the space center and landing atop the RnD. - @Alpaca Z Video here. Mass of 5.8 tons. Vertical launch using a whiplash ramjet engine, which was staged prior to orbital insertion. Resonant orbits with Kerbin and Mun assists were used to set up a KEKKJ gravity assiste route to save fuel. Spider engines were used in a two-stage Laythe lander design to save weight, and EVA construction was used to rebuild craft to negate the need for decouplers or rebuild the craft (or get away with only bringing one chair). Landings were otherwise routine apart from an incident on Tylo where the lander fell on its side, requiring an intuitive solution to rebuild the craft in such a way it could use redundant engines as support pillars. The video is very well narrated and goes into much more detail regarding the craft's design and flight plan, I highly recommend watching it to get the full picture of this mission. - @camacju Video here. Mass of 5.2 tons (Current Record!). This mission not only shatters the previous record, but does so with an impeccably made video. Launch mass was saved in numerous ways, one of which involved using tiny flags in place of landing gear for the horizontal KSC Runway takeoff. EVA construction was used to reassemble the craft(s) into what was needed at any given point during the mission. The vessels flown and techniques used are difficult to describe, so I highly encourage a watch of this mission to see some of the best of Kerbal engineering. - @camacju and @Ultimate Steve Grand Tour, Video here. Mass of 7.6 tons. This is a meticulously crafted and borderline perfectly executed low mass mission. This was not only a Jool 5, but also an entire grand tour weighing not even 8 tons! The video's excellent editing allows it to speak for itself, and I highly recommend you watch this mission to see perhaps the greatest low mass mission in the history of KSP. Low Cost - @jinnantonix Video here. 34,663 funds. The thread's first low cost submission! Using a low cost launch vehicle and a K-E-K-K-J flyby route, the mission put Val and a fuel-tanker station in elliptical Laythe orbit. From there one lander tackled Laythe, and another tackled the other four moons, with an extra few stages for Tylo. It is worth mentioning that this mission used no electrical charge and relied entirely on engine gimbal and some RCS to steer. On the way back, a double Eve flyby helped slow down, so an aerocapture could be done at Kerbin, where Vall proceeded to parachute onto the VAB. - @camacju Mission here. 24,070 funds. This mission used a SRB powered launch stage and a terrier powered transfer vehicle to get the landers to Jool (after numerous gravity assists). A dedicated Laythe lander tackled the ocean-world, while a multi-stage Tylo lander tackled the rest of the moons, and returned the brave Kerbonaut Wildard Kerman to Kerbin. Before heading back however, the new space-construction method was utilized to steal a solar panel from the transfer stage, marking the first time this creative form of staging has been used. Mission here. 17,635 funds (Current Record!). This mission is a more stripped down version of @camacju's previous low cost mission. This mission featured a visit to Laythe's ocean floor, and utilized eva construction to manually remove empty fuel tanks from the mission. Additionally, eva fuel tanks were used to refill the brave kerbonaught's jetpack to enable fuel savings by extended jetpack use. Low Parts - @bayesian_acolyte ISRU, Album here. A small, single stage craft comprising of 31 parts. Bayesian_acolyte said there could have been some part count improvements, but even without it the mission still did so much with so little. This mission shows just how far ISRU can be stretched, especially with that Tylo landing. - @Majk Thread here. A simplistic Jool 5 mission consisting of only 30 parts . The mission began using a very basic launch stage, and flew to Jool using a long nuclear ship. Lander reuse enabled part count savings, and usage of the nuclear ship as an ablative heat-shield helped return Val to Kerbin's surface in one piece. - @Majk Video here. Easily the most simple Jool 5 mission completed to date, accomplished using only 9 parts (Current Record!). This mission started with the 9th part, an RTG, stowed inside the command pod before installing it in orbit. It is also worth recognizing that a clever method of timewarping in the tracking station enabled refueling to take place while utilizing only a single RTG. The submission takes the form of a short, concise, and wel narrated video, and I highly encourage giving it a watch. 2nd Level - @jinnantonix ISRU, Album here. Used a big launch with a self-refueling vector-powered lander that made multiple Laythe landings and mined ore from every moon. Two kerbals were landed on each moon and the lander was recovered at KSC. - @Kerbolitto ISRU, Album here. Excellent mission done using two space shuttles capable of refueling on moons. Absolutely amazing job. In all things I ever thought I would see happen in KSP, a space shuttle landing on Tylo was not one of them. - @Marschig ISRU, Videos here. Not one, not two, but three ISRU planes flew to Jool and to all five moons on both the 3rd and 2nd levels. The SSTOs also visited Duna and Minmus in their missions before landing back at the KSC. Truly exceptional. This is the first time I've seen three Jool 5s all submitted at one time! - @PhoenixRise86 Album here. Used a mothership for the first part of the mission, then resorted to ions to get to Ike and Minmus, then safely back home. Also, this is the first 2nd level mission to not use ISRU. - @GRS: Album here. The highly anticipated Sheep v2 did not disappoint, and went above and beyond by visiting not just Jool's moons but also Kerbin's and Dres. Used massive nuclear boosters to get around the Jool system and the Tythe lander to get two Kerbals on every moon and Dres, before using the Sheep v2 to land the entire crew on Minmus and Mun. Spectacular! - @Xurkitree ISRU Video here. This modded mission utilized ISRU, a nuclear mothership, and eight aerospikes to land on all five of Jool's moons with Cerdrin and Lodous Kerman. Returned the lander and mothership to LKO where a separate rocket retrieved the crew. I highly encourage watching the video submitted, it is excellently edited and the music supports the awe of the mission. - @QF9E Thread here. This mission used a blunt-force approach by lifting off on a powerful launch stage, and made quick work of Jool's moons. The moons were all visited by one lander, which dropped various attachments that helped it land on some of the bigger moons. At the end of the mission, the three brave kerbonauts safely touched down in the ocean, and a BFR style spacecraft recovered the remains of the lander in Kerbin orbit for historical preservation. Truly an impressive mission indeed! - @Mars-Bound Hokie ISRU Mission here. Using the Anubis II SSTO, Tancan, Fernal, and Kenby Kerman flew to Minmus to refuel, then blasted off for Jool. After touching down on Laythe to refuel, the crew went for Bop, then to Tylo. After landing with no liquid fuel to spare, the Anubis II was refueled, then launched for Pol. After a risky auto-piloted landing, the ship refuel before bounding to Vall, where the crew had a group picture. Heading back to Kerbin, a mix of brute force and aero-braking was used to get the trajectory needed to get back to the KSC, and then the crew refused to ditch the plane and pulled off the legendary runway landing. - @king of nowhere Mission here. "And so I completed the Jool 5 in day 383, 1 hour and 9 minutes of a new career" are the words typed by @king of nowhere at the end of the mission thread, and fundamentally capture the astronomical accomplishment documented within it. In a career save speedrun, it was decided to focus on a Jool 5, and the mission was optimized for time rather than mass or cost. The amounts of delta-v put into each maneuver to achieve bullet-like trajectories around the Kerbolar and Jool systems is simply jaw dropping. Over the course of the flight, the La coscienza di xenon and its landers managed to plant flags on all 5 moons within a 12 day window, which I don't believe has ever been done before. If you wish to see the chronicles of a one-of-a-kind, record setting Jool 5 mission, the flight of the La coscienza di xenon is the mission thread for you. Grand Tour Mission here. @king of nowhere's second Kerbalism Grand Tour, but with radiation shielding 3 times less effective, bugs, life support issues, frantic crew members smashing fuel cells and dumping food overboard, and so much more! This mission chronicles the Nail Bolt on its tour around the solar system, finding monoliths on every world and making it back in roughly two decades. This mission thread covers the begins, rebeginnings, redesigns, quick fixes, and compromises that took place during the Bolt's journey not just to Jool's 5 moons, but to every other surface as well. This is one of the most thorough submissions the challenge has seen, and is a great resource for those considering Kerbalism entries of their own. - @Lyra Mission here. A single launch mission! Using a spaceplane for Laythe, a notably slim Tylo lander (with a reusable upper stage for Vall), and an ion lander for Bop and Pol, this mission was a pleasant, self contained romp around the Jool System. One unique aspect of this mission I've seldom seen elsewhere was the use of claws on the nuclear mothership's outer hull. This allowed the landers to not need docking ports and attach to the hull like barnacles. A very clever, mass saving decision for the landers for sure! 3rd Level - @iAMtheWALRUS Grand Tour, ISRU, Album here. Used SSTOs to launch the mission and used moon hopping to get around the Kerbol system. Very nicely done. Also, first 1.4 submission - @sturmhauke Album here. To put it in the words of the pilot them self; "A mostly reusable mission to all 5 of Jool's moons. Single launch SSTO carrier drone, with a separable mothership and 5 landers." Very well done and efficient mission. Used fuel cells to power ion crafts for Bop and Pol, sent a plane to Laythe, and conquered Tylo with a rocket lander. - @mystifeid Album here, ISRU. Used two launches to put a mothership and a universal lander into orbit. Then used left over launch stage to boost to Jool and then around the system until it ran out and was staged at Tylo. Bob landed on every moon, accompanied with a different Kerbal for every moon. Very nice mission, and even had the added bonus of a near KSC landing. - @PhoenixRise86 Album here. Used a single launch of pure rocketry, no jets, ions, or nukes used in the entire mission. This mission did the Jool 5 mission in style, with some of the most interesting landers I've ever seen, including an aerospike Laythe plane. - @Marschig ISRU, Videos here. Not one, not two, but three ISRU planes flew to Jool and to all five moons on both the 3rd and 2nd levels. The SSTOs also visited Duna and Minmus in their missions before landing back at the KSC. Truly exceptional. This is the first time I've seen three Jool 5s all submitted at one time! - @jinnantonix ISRU, Video here. Of all the Jool 5 missions I have seen in this thread so far, none treat their Kerbals better than Jinnantonix has. The craft was modular in design and split into several different arrangements for various landings, and came with a gravity spin for deep space transit. Very considerate, and very awesome. - @Grogs Album here. Two launches to build the main ship in orbit, one crew launch for realism. Used a giant transfer stage to get the landers to Jool. Chemical engines pushed the landers about the Jool system, with nine Kerbals in total being involved in the mission. Once the landings were completed the mothership returned to Kerbin where a fourth launch collected the Kerbals and returned them safely to Kerbin. - @Pipcard ISRU Thread here. A well executed, eight Kerbal mission with one of the longest ships I've ever seen in this game. Excellent mission that toured the Jool System in an engaging thread. Mission was assembled in multiple parts, flew to Jool, landed on the moons (being sure to refuel on Bop and Pol when needed), EVA jetpacked off Tylo, and the crew was returned to Kerbin by a separately flown space plane. - @Kerbolitto ISRU Mission here, here, and here. Kerbolitto's second submission! Using a space shuttle with several surface experiments, a crew of eight explored the system. The Tylo landing was done with perfect margins, landing with no fuel left! This craft may also hold the record for lowest TWR launch of Bop in history, and an outpost on Laythe with a mini-plane was even constructed. Bob chose to stay behind and man the base while the crew returned home. Excellent end to an excellent mission! - @Ksp Slingshooter Album here. Assembled the main ship using multiple launches, then flew to Jool, settling in an elliptical Jool orbit with some help from a few gravity assists. From there the landers detached and flew to their moons, one by one and completed their landings. Due to some unexpected occurrences at Laythe, the Vall lander swooped in and rescued the Kerbal, taking both back to the mothership. Without enough room in the command pods for everyone, two brave Kerbals rode back to Kerbin on ladders, detaching and re-rendezvousing during timewarp. A rescue craft was launched, and met the mothership just in time, with only three minutes to transfer the Kerbals before a fiery re-entry. Truly a Kerbal mission! - @RoninFrog ISRU Thread here. Using the gloriously huge HMS Sauron, Jeb and 16 friends took to Jool in this massive SSTA. First they stopped at the Mun, then flew to Pol, then Tylo, then Vall, Laythe, and finally Bop. On the way back to Kerbin, time and fuel and the positions of the planets made a Duna landing prove itself most useful, before heading back to the Mun, and finally, back to Kerbin. This 1 stage mission has some amazing screenshots in its thread, as well as most amusing comments for each picture. If you're wanting to learn more about an ISRU approach, I suggest giving this mission a peak. - @OutInSpace Video here. Using a total of eight launches, this mission's mothership was constructed methodically, complete with an enormous pair of transfer boosters. After heading to Jool directly, the mothership flew to Tylo, Vall, and Laythe by itself, and sent an ion craft to Bop and Pol instead. After numerous attempts, the Laythe plane was finally able to show what it could do, and the 5 crew returned to Kerbin orbit, where they were picked up by a landing craft. If you want to see the nitty-gritty maneuvers used during a Jool 5 mission, I suggest you check out this mission's video. Its editing and methodicalness make it an unintentional flight-tutorial for getting to Jool. - @Entropian ISRU Mission here. Using a 5 meter tank with 5 meter tanks strapped on the side and a large cluster of mastodon engines, the craft rocketed off the pad to Minmus, where it refueled and went off to Jool. Landing on Laythe proved to a close call, with ZERO delta-v remaining upon touchdown. From there the ship bounced to Vall, Tylo, Pol, and Bop, before making a rough splashdown on Kerbin. It is worth noting that the crew did forget to put a flag on Bop. However since every other mission criteria was met and the craft was landed on Bop it is still being counted. - @GRS Grand Tour. Mission here. This time with the Sheep v4 the Jool moons were visited again, along with 60 other destinations! Relying heavily on ion power, landing after landing was accomplished visiting worlds close to the sun, around Jool, and even outer dwarf planets. So many worlds were mentioned that the Jool 5 portion is only a tiny fragment of the overall mission. There is genuinely too much in that mission to describe here, so I highly suggest you check out the most expansive sheep yet's thread! - @s_gamer101. Mission here. This mission began with the launch of an enormous reusable launch system that placed the main ship in orbit. A trip to Jool ended with a fiery aerocapture above Laythe, where two of the crew members took a small spaceplane to the surface. After a tricky fuel situation in which drop tanks were accidentally kept as huge pieces of ballasts, the Tylo tug was used as an extra stage to boost the main ship. This proved to be enough delta-v, as once the landings were completed the ship cruised back to Kerbin, where they parachuted safely to complete the mission. - @AlpacaMall Mission here. This mission began with the launch and orbital construction of the KSS-J "Orca". Engineer construction added fuel lines and removed unneeded RCS thrusters, and the craft departed for Jool with a reusable lander upper stage, with lander stages for Laythe and Tylo. The landings were completed in the following order: Laythe, Tylo, Vall, Pol, Bop. From Bop, the Orca was left to serve as a relay station while the crew module left for Kerbin. The vessel landed with all the crew and 23458 science. - @BeanThruster Album here. This mission began with the launch of Vapidity, the mothership used during the mission. Instead of going to Jool, Vapidity made its first flight to an E-class asteroid so it could refill all of its fuel tanks (it launched almost empty to save weight). After flying to Jool, the first landing took place on Tylo, before leaving the engine nacelles in case later refueling was needed. Next, the last stage of the Tylo lander was used to land on Vall, then the lander flew solo to Bop where it awaited the rest of the ship. Vapidity took the time to take a spaceplane to Laythe, then went back to low Tylo orbit to refuel. Vapidity met the Vapidlander at Bop, conducted the landing, then went to Pol to do the same. Vapidity returned to Kerbin before the crew landed using the Laythe spaceplane. In total, the crew collected 20113.6 science. - @RuBisCO ISRU Album here. This mission began with a lot of mainsail engines to push the main craft into orbit, and delivered not one, but seven Kerbals to the surface of each moon. The first visit was Pol, where cleverly built piston legs kept the refueling craft perfectly level. Next was Bop, then Vall, then Tylo, where a rover and lab were brought to the surface and returned to orbit (except Tylo where it got left behind). For the Laythe landing, the crew took down a spaceplane, as well as a helicopter and a floating lab with plane-refueling capabilities. The helicopter was used to collect science from the local area, and after being refueled, the plane returned to orbit. After the main ship was refueled on Pol, the crew returned home. - @18Watt ISRU , Mission here. This mission is nearly identical to 18Watt's previous submission, but now has accommodated a unique Kerbal for each moon, bumping it from a 1st to a 3rd level submission. Main ship refueled on Minmus before heading to Jool, refueled on small moons, and pilots Val and Billy Bobfurt flew each unique specialist to their respective moons. - @Krazy1 ISRU, Album here. This mission was done with the Principia mod, which makes gravity and orbits behave more realistically. The spacecraft used was the "2 by 4", named after its two mammoth engines and four nervs. First the craft launched to Minmus, then visited a passing asteroid, then went back to Minmus to refuel, then shot off to Jool. After the Laythe landing, there was some trouble getting to Vall due to orbital issues. After Vall came a very bouncy Tylo landing, which was followed by a Pol landing, and then a Bop landing. It is worth noting that Bop is orbiting retrograde in this mod for orbital stability. After completing the landings and experimenting with weird orbits, the 2 by 4 traveled home, refueled on Minmus to prep for landing, and then touched down safely on Kerbin with its crew of 5. ISRU, Album here. This mission utilized an orange and gray aesthetically pleasing spacecraft. Once launched into orbit, the craft refueled on Minmus, then shot off to Jool where it landed on Vall, then flew to Tylo where it performed this landing, before nearly burning on Laythe, then finished up with Bop and Pol. Upon returning to Kerbin, some excess ore was turned to fuel to save weight, and the crew splashed down 10km from the KSC. - @Kimera Industries. Mission here. This mission's mission thread chronicles the Avocado on its journey to Jool's moons and back, using appropriately named components and landers. Due to its nuclear propulsion, the escape burn was split in two, though did not go gently into that good night, and upon arriving to Jool, took use of a convenient Tylo assist to go almost directly to Laythe. From Laythe, a lander was dispatched to Vall and Pol, then the entire ship reunited and migrated to Tylo where the landing was achieved on the fifth try. Next came Gilly 2.0 Bop, where an interesting SPOILER was discovered. Upon returning to Kerbin with little to no time for caution, the cargo container and its draggy friends kept the craft from overheating during airbraking, and the crew landed to live another day. - @Geryz MODDED, Video here.Pushing past 1000 tons and assembled over 8 launches, the Hephaestus ship was made to be flashy and ludicrous, and it does a good job at it. The mission uses kerbalism simplex to add life support, while radiations are turned off. An imperfect gravity assist from Tylo added inclination and complicated the mission. A nuclear-powered ion lander was used for the minor moons, its TWR barely sufficient for Vall. Hephaestus was burned in atmosphere during reentry, leaving behind only the shielded crew pod to carry the crew to safety. Jeb's Level - @Xurkitree Grand Tour, ISRU Album Here. Collected 19,711.3 science from Jool on a girl's night out mission with no lack of gravity assists. A note from the author said that the mission greatly improved their skills in KSP and proved that fact well with the insane gravity assists they pulled off. Also first Jeb's Level on the new thread yay! - @ManEatingApe Video here. And here. And here. And here. And here. And here. Collected 16,532.0 science from Jool. There isn't anything I can say about this mission except you need to see it for yourself. Exclusively low tech was used, and collected in space science from all biomes. This mission did the near-impossible, with primitive parts, and landed all Kerbals safely back on Kerbin. - @SolarAdmiral Video here. Collected 42,296 science from the Jool System. Single launch on a cluster of three meter parts, before heading off to Jool. Started with Laythe first, landing using a floating platform. Science was collected with a small jet-powered boat. Next stop was Tylo, where a rover was used to collect science from many biomes. On Vall one landing was done, and a hop added to it before heading to orbit again. Numerous biomes collected from Bop and Pol by hopping around in their low gravities. Direct shot home and landed all seven Kerbals to tell the tale. Absolutely astounding mission! - @jinnantonix ISRU Video here. Collected 82,510 science from the Jool System. Single launch, one much smaller than you might expect. Used a plane to gather large amounts of science from Laythe, dove into Jool's atmosphere, grabbed science from almost if not everywhere, and even managed to use the Laythe plane as the final stage on the Tylo landing. Had an artificial gravity system to facilitate the kerbals, and landed back at the KSC. Honestly jinnatonix managed to do so much in this video I can't describe it all here so I suggest you just watch the video. Amazing job. - @GRS Album here. Collected 28,643 science from the Jool System. The long awaited Sheep mission that satisfied both the Kerpollo and Jool 5 requirements led by Simone Kerman that explored the Jool system and returned home Apollo style. The mission had a heavy launch and went to, around, and from Jool using a massive nuclear stage. The usage of the Scifi visual pack gave the mission a unique look as it took science from every moon (including Jool's upper atmosphere!) in style. Incredible. - @Jim123 Video here. Collected 8780.9 science from the Jool System. Single giant launch put a large nuclear mothership in orbit. Flew straight to Laythe where the landing was completed with a dual stage to orbit (and Jeb's jetpack). From there the crew went to Vall and landed, before heading to Tylo and dropping one of the most Kerbal looking Tylo landers I've ever seen to the surface. After Tylo biome hopping was used on Bop and Tylo, before a pair of service modules detached and went back to Kerbin, boosting each other home where the crew landed. Nice video. - @jost ISRU Album here. Collected 16940.2 science from the Jool system. Flew to Jool using a long nuclear mothership. From there an ion ore probe helped find ore on every moon but Laythe for the rocket lander. Laythe used a three seat plane for the landing, and even found a geyser while on the surface. Landed on Tylo with 1m/s to spare before refueling, and landed everyone safely back on Kerbin after leaving the nukes in a graveyard orbit around Kerbin. Excellent! - @Beriev Album here. Collected 49430.1 science from the Jool system. This entire mission was done in a 6.4x solar system. Launched off the pad with an absolutely enourmous rocket, fittingly dubbed the 'Absolute Unit'. Used many kicks to get out to Jool, where the ship split up to tackle the moons. For Laythe and Tylo, ascent vehicles were landed separately, before the crew arrived on-surface. Later, both sets met up at Vall, then flew to Pol, then Bop, and then to Dres. After a fun journey, the Absolute Unit returned to Kerbin, and the crew landed safely. This mission has an incredible execution and design, as well as a well-captioned Imgur album. I highly suggest giving it a look. - @Pro100kerbonaut Video here. Collected 10238 science from the Jool system. This mission was done with a rather interesting, asymmetrically balanced ship, and had quite the bouncy ride. On Tylo parkour was done, on Laythe swimming. On Vall two landings were done, and on Pol and Bop the lander bounced around. This mission used a combination of a gravity assist off Tylo and a retro-burn to capture at Jool, and upon return to Kerbin parachutes were attached to the crew section using a klaw. A fun mission with great editing. - @king of nowhere ISRU Mission thread here. Collected 105136 science. This mission was insane from its conception, with the goal to collect every single bit of science from the Jool system as possible. While this goal was not ultimately accomplished, the mission is still one of the greatest Jool 5 submissions I have ever seen. To collect science on each world, a durable lander known as the Dancing Porcupine was deployed and driven on all moons but Laythe. For Laythe, a spaceplane called Absolutely NOT Albatross was used to collect science from each biome. In fact, Absolutely NOT Albatross did even more than just Laythe. Using a multi-stage attachment, Absolutely NOT Albatross visited the lower atmosphere of Jool and returned to tell the tale. The craft's brave pilot even took an EVA report while in flight before ascending. The main ship dubbed the Flying Christmas Tree, and was capable of refueling on low gravity worlds. Upon returning to Kerbin, a craft launched to return the brave Kerbonauts to their home-world. Having visited every biome on every moon, it is no surprise that this mission amassed more science than any other Jool 5 mission before it. I highly recommend viewing this mission's main thread. Amazing job king of nowhere! Mission thread here. Collected 11395 science from the Jool System. The sheer amount of effort put into this mission cannot be overstated. King of Nowhere started this mission as a nanocristalline diamond caveman mission, which in short meant no contracts, no facility upgrades, no quicksaving, on career mode, while starting the save with severe limitations. While the mission ended up needing quick-loading, it still is eye popping to see just how much work went into it. Each launch (in the VAB) was limited to 18 tons maximum, so a work around was used by having docking ports around the base of the rocket, to which separate boosters would be docked using a runway-launched rover. This meant that many launches required multiple launches of booster attachment vessels before the rocket itself could attempt to leave the pad. After over 100 launches, the Navis Sideralis Neanderthalensis and all its cargo were ready, and the ship departed for Jool, leaving a most amusing pattern of drop tanks in its wake. Upon reaching Jool, disaster struck when the Tylo lander suffered an anomaly, and quicksaves were needed to complete the Jool 5. While at Jool, science modules were discarded after use because a lack of KSC upgrades prevented their resetting, and every aspect of the mission, from flying between moons to the landings themselves, were executed with meticulous testing and prior calculation. I cannot possibly explain everything this mission did in this little blurb, so I highly encourage anyone who wants to see some of the best Kerbal engineering I've ever seen to check out the linked mission thread above. ISRU Mission thread here. Collected 142744 science (Current Record!) from the Jool system. This mission is perhaps the greatest Jool 5 missions to ever fly. A worthy successor to @king of nowhere's previous submissions, this mission collected practically every single piece of science that the Jool system has to offer, with only a few dozen science bits unobtained. In addition, the mission visited every single anomaly in the Jool system, performed circumnavigations of every moon, and flew a two-crew craft into Jool's upper atmosphere to collect science, and deployed an aircraft carrier to Laythe. The mission's thread linked above follows the journey of the Flying Christmas Tree 2, a massive mothership capable of landing and refueling itself, Leaping Mantis, a rover designed for climbing steep grades on alien worlds, Tamarromobile, a larger rover for Tylo, Phoenix, the spaceplane for Jool, Absolutely Not An Albatross, an SSTO for Laythe, and Garibarge, the aircraft carrier for Laythe so that Kerbals could disembark from Not Albatross and collected surface samples from Laythe's ocean biomes. The mission began with Flying Christmas Tree 2 being equipped with the landers, planes, and aircraft carrier. Use this link here to see the majesty of Flying Christmas Tree 2 in all its glory -> (https://youtu.be/h61wplb0DRw?si=HlNYwxnYPkPaem2k). From there, it flew to Minmus to land and refuel, and then departed for Jool. The following efforts to circumnavigate all 5 moons and locating the anomalies require an entire thread of its own, requiring one to view and read the entirety of the mission thread linked above. Out of all the Jool 5 missions I have ever reviewed, none have exhibited such effort or gone to the extent shown here. This is not one of many Jool 5 missions, this is the Jool 5. - @OJT ISRU Mission thread here. Collected 26871.3 science from the Jool System. This mission thread contains some of the most eye-catching, visually stunning KSP screenshots I have ever seen in a Jool 5 submission. The mission itself was tested and proofed in sandbox, and consisted of a long, skinny mothership, a spaceplane, and an ISRU lander for Tylo. With the lander and plane hanging from docking points on the main ship, the craft boosted to Jool and used a Tylo flyby to capture. Visiting Vall first, the lander took around 100 days to refuel. The ship then flew to Pol where the relatively tiny lander (in relation to the mothership) flew to Pol's surface and back numerous times to refuel the main ship before it could head to Bop. At Bop a kraken was discovered, and on Tylo the crew found it refreshingly eventless. The last destination was Laythe, where the plane and lander were left in orbit so the main ship could return to Kerbin. A return craft returned the crew and science, and crew XP was had by all. - @Robin Patenall Mission thread here. Collected 61174.6 science from the Jool System. This mission began with the construction of the Emerald Star, a large and reconfigurable interplanetary vessel that required 17 launches to complete. Once built, the Emerald Star used Eve and Kerbin gravity assists to efficiently sling itself to Jool and started with Tylo. Using one of the Emerald Star's 3 drive cores to send itself down to a lower Tylo orbit, the lander successfully brought the crew to and from the Tylic surface. When the mission reached Vall, a magical anomaly was discovered, one which would prove to be only one of many odd discoveries made on Jool's moons. An SSTO found one on Laythe as well, during one of its three total landings. A monolith was found on Pol, and a deceased kraken on Bop, one which caused a crew member to lament their inability to bury it. Once the landings had been complete, the remains of the Emerald Star returned home, where it was parked in Kerbin orbit awaiting future assignment. - @problemecium Mission thread here. Collected 8755.7 science from the Jool System. This mission thread covers the finally completed tale of the Aletheia, a massive, nearly 1.3 kiloton mothership. With numerous cargo bays, it brought landers, an SSTO, a deployable space station, numerous pieces of scientific equipment, and two ARKS to return the crew to Kerbin if needed. Upon construction, Aletheia and its seven crew members proceeded to Jool, using 46% of its total fuel. The transfer section was left behind in Laythe orbit while the rest of Aletheia continued on. After Laythe came Vall, where one of the ARKS was used to refuel the Tylo lander to enable it to tackle Vall (the ARK was then joined to the deployable station and left behind). The lander then tackled Tylo, and was left behind for future use. Bop saw the discovery of a hopefully deceased Kraken, and Pol marked landing number 5. This romp unfortunately depleted Aletheia of the fuel sufficient to return to Kerbin, so the second ARK spacecraft brought the crew home safely, using a Mun assist to tweak its final trajectory. This is one of the more aesthetically pleasing Jool 5 missions, and done in career mode in a very well typed out and necromanced thread, so if you are a fan of large stylish motherships, I would recommend giving this thread a view. Gatecrashers / Honorary Mentions - @JacobJHC Grand Tour, video here. Giant single launch craft, also visited every planet and moon from the OPM planet pack. Very big. Gatecrasher because crew hasn't landed yet. - @Fraus Mission here. There's nothing that can be said about this, other than that this mission definitely had more thought put into it than any other Jool 5 I've seen. - @cqIpb Mission here. This mission was flown on an Xbox, and pushed the console to its framerate limits! cqIpl was inspired to do a Jool 5 mission after finding this thread, and despite not being able to land on Laythe due to lander instability, still had a lot of fun finishing the rest of the mission, and took a few great screenshots along the way! As of writing this, cqIpb is still new to the KSP Forums. Welcome, we're glad you're here! - @Alpaca Z, using a craft built by @Lt_Duckweed (with permission) Grand Tour, ISRU . Video here. Using a rather simply built SSTA, this mission was a simple case of flying around the entire solar system and refueling everywhere. This craft utilized air-fans, ions, vectors, and nerv engines, allowing it to be not only capable of high efficiency maneuvers, but also those requiring high TWRs. A highlight of this mission was the strategy to use EVA construction to rebuild the back of the plane to enable it to land vertically on Tylo's surface. Why bring landing legs when you have wings that could do the job just as well? This mission's video submission is also of a high quality, so I recommend giving it a view. In all, the crew of three finished their grand tour in only 15 years and 117 days! Efficient and speedy Moved to Honorary Mentions due to the fact that the crew could not exit onto Tylo's surface.
  17. so, you want to launch a ship from a plane, send the ship in orbit, send the plane back on the ground. how is that possible without the game authomatically deleting the object in the atmosphere while you're not controlling it? looks like the tricky part
  18. i'm not an expert on this, but it's generally accepted that the more mods you install, the more likely it is for the game to crash. especially for mods that alter the game significantly, like RO. easiest path is to remove it., maybe the game works afterwards, and you lost nothing. even if the game doesn't work anymore, you can still go in the game folder, take the save files related to your career (or challenge, or whatever you're doing), save them somewhere safe, and put them back in their folder after you reinstall the game - and the mods you had while it still worked. this should ensure you can save your previous games. another good tip is, make multiple installations of the game for different mods. i myself have 5 different installs. this way, if your latest mods crashes the game, you lost nothing.
  19. @JacobJHC says he doesn't have the time anymore to follow this challenge. He asked me to take it over. In the near future, I will review all pending submissions (except my own) and start working on moving the challenge to a new thread.
  20. trying a sort of nanodiamond caveman in the whirligig world planetary pack. i call it nanodiamond because i have tech at 10%, though i cheated infinite money because i already went through the whole "make a crapton of easy, boring contract to gather enough money to run a real mission" before, and i'd rather cut to the interesting stuff. i also enabled saving and loading, because i can't consistently land on mesbin. whirligig world starts from the planet mesbin, a rocky giant with a very fast rotation. at the equator, gravity is 1.3 g, you need some 1500 m/s of ground-relative speed to orbit (thanks to rotation helping). but there is no atmosphere, so you need to rocket brake every landing. it's similar to landing on tylo, really; it requires a bit less deltaV, but more thrust. which is why i'm not even trying to make this without quickloading, landing is difficult and the slightest mistake will lose the craft. anyway, there are a lot less biomes available than on kerbin, and so i find myself needing to stretch the missions with limited techs. I don't have enough deltaV with a single launch, but i'm nowhere near close to unlocking docking ports. so I got creative when needing to give my ships a boost You don't have to be docked when you can embed your capsule inside a glove-like structure. I called this ship "poor man's claw" here testing, it works pretty well for deorbiting a crewed module after it run out of fuel. unfortunately, the test also showcased poor man's claw doesn't have enough fuel to land itself, after spending most of its allotment to reach Jeb. so I have to redesign it to jettison the tanks and engines, and send it up again; boost the module with Jeb in low orbit, then jettison its tanks and engines, and send up another poor man's claw to bring jeb on the ground. oh, and another for Val. on the plus side, next i'll unlock the stayputnik, so i will at least be able to treat the poor man's claw as expendable EDIT: I failed to consider that the pod to be rescued would not sit perfectly symmetrical. it was very hard, fighting against the control of an asymmetrical ship while trying to rocket-land on twice tylo's gravity. without SAS, because both my pilots were in orbit, waiting to be rescued. but after several failed attempts, i managed to crash-land in a way that left both pods intact.
  21. the ksp1 section of the forum seems a lot less active than it used to be before ksp2 released. if it recovered, it didn't go back to previous levels.
  22. can't you reload the game? if you have decided to make a no reload career without having much practice, then a golden advice is: don't send a crew unless you really need to. in a rescue mission, you most definitely don't need no crew. especially not a crew of 5. anyway, there are ways to rescue your kerbals, but the fast ones require some skill. namely, while your ship is still in kerbin's SoI, you can send another ship, with lots of deltaV, and aim to pass close to the first one. it's tricky because the game won't give you a close approach. So you have to take your original ship trajectory, decide on a position, for example mark a point where the ship will be in 10 days. then find a traectory with the rescue ship that will pass close by in 10 days. once you're close to the ship to be rescued, use the navball. it will take quite a bit of fuel too, especially to revert the trajectory after the rescue. if you accidentally stranded 3 kerbals on a kerbin escape trajectory, and then you accidentally killed 5 kerbals on a rescue mission, then you most likely don't have the skill for that maneuver. which leaves the slow option. your lost ship will go in solar orbit. just send the rescue ship in solar orbit to rendez-vous with it. it's not much different than doing it in kerbin orbit, it's just a lot slower.
