Jebediah: Hey, Bob! Wait... you know, after arriving back from the JOOL-5 mission, the Kerbal Space Program received new fundings and contracts for a Laythe Base and looking for Kethane throughout the system. This is great and I'm really happy, but I hate the amount of attention what we get from the press and the people! I need some time on my own... so, I have an idea. Bob: Yeah, I understand that, I feel the same. What's your plan? Jebediah: I have landed on Laythe what I pretty much enjoyed. I want to go back. Bob: Sounds good! Jebediah: Yeah. And I haven't landed on any of the other moons, so I want to land on them too. Bob: In one go? Seriously?? Jebediah. Yes. Bob: Are you CRAZY??? Jebediah: Ahh... you act like anyone else. Bob: Okay, Okay, Sorry. But I think this is a huge plan! How would you get the funding? How many launches? What about planning the ship? Jebediah: I have arranged everything with my lead engineer, Ziv. We figured out that I can use a very small lander with a commander seat only. Even for Laythe... Bob: WHAT? Are you CRAZY???? Jebediah: Please, can you react something else, too? Bob: Ahh, sorry. I'm getting curious, tell me more! Jebediah: so, here are the plans for the ship: Bob: Wow, looks impressive... but maybe too small for this huge mission, don't you think? Jebediah: No. Small ships can go further out with the same amount of fuel. The small lander needs very little fuel so it can easily be refueled many times. Bob: True. Parameters? Jebediah: 170 parts, 132 tons. No lag! And 4648 m/s Delta-V in the lander... Bob: WHOA... I guess our space program will profit from this new technology! Jebediah: Definitely! Bob: And how many launches will you use to put this together and send to Jool? Jebediah: One... Bob: WHAT? That's CRAZY!!! Jebediah: YOU are getting crazy, hehe. Bob: But how? With what? How many orange tanks and Mainsails? How many stages? Jebediah: Come and see the launch. Tomorrow, when the sun is right above us... Bob: So, at noon. You lunatic.... okay, see you tomorrow! ---------- TOMORROW ------------ All system is go. 3,2,1.. LAUNCH! Stage 1... Stage 2... Stage 3... Good job, we are in space with one launch. Now burning for the interplanetary travel to Jool... look, how close Minmus is! Arriving at Laythe: Jebediah separated with the lander, with the Laythe module attached on the bottom. Jebediah: YEEEEEHAAAAAAAAHHHHH!!!!!!!! (Bob in the background: This guy is crazy......) Slowing with the Jets at the last meters...: And Jebediah is on the ground of Laythe!!! Again. Ascending with the Jet engines.... Dropping the Jets when they had no air anymore, and changing to rockets: ...and Jebediah arrived back to the main ship after the successful Laythe landing! for the full story: http://imgur.com/a/1EWoP#0

Hi Daffit, that's a massive ship! Congratulation, you have accomplished the JOOL-5 challenge! You can add the JOOL-5 badge to your profile if you want... Settings at top right, then Edit Signature in the left menu - copy there this without the spaces after the four "["-s: [ URL=http://forum.kerbalspaceprogram.com/threads/57197-THE-ULTIMATE-JOOL-5-CHALLENGE-land-Kerbals-on-all-moons-and-return-in-one-big-misson][ IMG]http://i.imgur.com/Z5hSyCv.png[ /IMG][ /URL] Yeah, that's a pity that you have to be careful about the part counts with big ships...

But for the other moons your jet engines are just dead weight. This challenge is about one universal lander... by the way I did the JOOL-5 challenge twice (I still have to upload the pictures from the second mission), one with different modular lander and science units, the second one with an ultralight lander with a commander seat which used an additional docked stage for Laythe (Jets) and Tylo (for deorbit/descent). Pictures coming soon, the link to that challenge is in my profile's bottom line:

Yeah, when I had the idea of this mission I have spent about 3 days thinking about the mission and writing/drawing ideas about what will be needed and how can I optimize the steps, the ship stages and the part count. In the next step I was testing my ideas on Kerbin or at Mun/Minmus (I posted pictures about the first lander prototypes). And, at first, you have to have experience with landing, rendezvouzing, docking, refueling, etc... I'm playing with KSP since a long time and I was thinking about this as the final challenge for myself in the game (but now I found something new... ). So yes, this is an extremely hard mission, but a very fulfilling when you can finish it at the end!

After the discovery of Kethane, Kerbals had new ideas about building and maintaining bases all over the system. The first bigger outpost was built on Eve and maintained by Jebediah. They knew it's the hardest body to get back from so they wanted to use Kethane as the propellant for the Return Vehicle. They built the mining base and Jebediah was working hard. In his free time he was wandering around with the rover. At the end of the mission he wanted to get off from the surface with the Kethane Jet driven rocket but it was not enough to get back to orbit. He get stranded on Eve! The Kerbal Space Program engineers started to plan a rescue mission... About The Challenge This challenge is about building a Rescue Ship and bringing back Jebediah from Eve to Kerbin, using the Kethane mod. There is a Rover (brakes on) and a weak Kethane Jet Rocket on the base, and a fully filled fuel station in orbit around Eve, you can use them if you want. Only one rule: you have to use Kethane Jets in your Rescue Vehicle (beside normal rocket engines). I was thinking about a point system for one launch, rescue Kerbals from Kerbin, how close you land to Jebediah, not using the fuel station, etc. but I realized that this is already a very hard challenge so everybody is a winner who can achieve it and bring back Jebediah alive. You may use MechJeb or parts like NovaPunch, KAS or other similar mods if they don't give you too much advantage. The goal is to have fun during planning and doing one of the hardest mission. And rescue Jebediah. The save file was generated with KSP 0.22 and with the Kethane mod so you need to install that one. But you can load the save file if you have other mods installed too. DOWNLOAD THE KETHANE MOD HERE (unzip and copy the Kethane directory into your KSP/GameData) DOWNLOAD THE SAVE FILE HERE (unzip into your KSP/saves directory) How Kethane works: - when drilling or using with the Kethane Jet engine it's like RCS so you can place the Kethane fuel tank, the Kethane Jet engine and the Drill anywhere on the ship. - when converting to liquid fuel/oxidizer then it works like a reversed engine: it fills the fuel tanks which would drive an engine in the converter's place. - if you want to exchange fuel between tanks on other stages which are not connected to the converter then you can exchange fuel between them by ALT+right click on the tanks and then in/out.

Wow Blue, 30 tons to Tylo? You Are CRAZY!!! I'm curious how you will done it!

mcirish3: cool, good to see you again, welcome back! Glad to hear that you have found some solution against the Kraken, thanks for sharing them! Hm, very unique main ship solution! And it looks funny now with this T shape! Keep us updated! Mesklin: Oh, how did you test the lander at Tylo? With Hyperlink or similar? If you know that it will be okay then that's cool. Show us pictures about how you progress!

Mesklin: Nice stuff, looking good! But what will push your ship to Jool? The lander's two nuclear engines? If so, it will take a while... and you will need to do 2-3 orbits between the initial burn. And I guess you will need refueling missions too. And I'm worried about your lander's capability for landing/ascent at Tylo. Will you use some additonal fuel pack for the deorbit burn? (it can be about ~800 m/s) And for a good ascent you should have at least 2.0 TWR...! But the smaller the lander's TWR the slower the ascent from Tylo's surface and so much more fuel/dV is burnt, so that way it's not 2400 m/s but can be 4000 m/s too!

Don't worry, I was playing KSP for months before this challenge. I think everybody needs to have some experience to do this huge mission. And I was planning this mission and my ship for about a week with a lot of testing around Kerbin, and one Proof-of-concept mission to Minmus and Mun. I enjoyed this too. You have to think in advance to prepare for everything! For the dV, remember that as you drop the Laythe/Tylo helping stages your ship will become more easy with more dV for the same fuel amount/engine layout. And you can send a refuel mission too. And try to go small: small lander, one Kerbal, no science. It will be a very serious mission that way too. And you might want to use the NovaPunch mod for bigger and more stable launch rockets. Laythe return and Tylo landing/ascent are the key parts of the mission. Other thing that you don't have to launch the mission in one! I used 3-4 launches and put the ship together in Kerbin orbit. And let me help you with my check-list: before final launch I checked all the modules on the ship by this list: - Control (cans and command seats can control only with a Kerbal) - Fuel - Engine - Fuel ducts, proper fuel routes - Enough S.A.S./Torque - RCS (only for parts that will move while docking, otherwise I don't like to use RCS because it is usually unnecessary if you have enough S.A.S./Torque and gives much to the weight/parts number) - Electricity (generators are for sure without light too and good for lowwer part number. Be careful with Solar panels, without electricity they cannot be opened) - additional parts for Mods: MechJeb, Protractor, MapSat or anything else what needs to be on your ship - Docking ports (they can be put on the ship backway too and this way you will not be able to use it in space so check all of them twice before launch!) - Ladder on the lander (very important to test at Kerbin because at Laythe and Tylo you cannot use your jetpack and if you cannot go back into your ship then the mission is over!) - Landing gears (strong enough?) - Crew check before launch (the Hitchiker's Storage stays empty if you don't fill them before launch!) Optional stuff: - Lights (optional, I usually skipped it for saving part numbers) - Science modules - Communications stuff if you want to send science - Living Quarter, Hitchhiker's Storage

dawg: after this long mission, arriving back to Kerbin in a big explosion without damaging the can is the real Kerbal way!

Vaebn: I like your idea to use Nuclear Engines, I was doing so too but later changed my mind. I also like a lot of stuff like using the lander engines only, or you won't stage or leave anything behind (except fuel;)), etc. But I want to argue some about the weight stuff: to land such a superheavy lander on Laythe and Tylo will use much more fuel mass than some "used only once" lander engines or other parts. I guess. And will you leave your fuel tanks in orbit around Jool or go into orbit? Because huge mass to orbit -> huge fuel consumption. But I think you will have to put it into orbit around Tylo at least because if you have 6587 m/s in your lander then it's just enough for the landing and getting back to orbit. I feel like the 0.82 TWR is low for Tylo, okay, you will use up about 60-70% of the fuel for landing so it will be more light and the TWR will be higher... but if you ascent with a high TWR then you will need around 2400 m/s to 45km orbit. But if you have low TWR, just above 1, then it can be 4000+ m/s too... so I hope you will get 3.0+ and then you will be good for back to orbit! I'm curious how it will go! Good luck and keep us updated!

Why should the dV decrease as your TWR gets higher? That just means that you get more thrust as your fuel takes less mass... And we have already done this mission so this is definetely possible! And I have just finished it second time, this time with only one launch and no refueling during the mission... (I will post the pictures soon!)

Hi all, I have designed a badge which can be added to your Profile Signature at the bottom if you want: to do this: go to the Settings (upper right) then Edit Signature (left menu, under My Profile), and add this image: http://i.imgur.com/Z5hSyCv.png

...and important to change these too: sit = ORBITING landed = False landedAt = splashed = False

When I started the mission I have decided to make a statistic about my fuel and Delta-V consumption, but I forgot them at some points and with undocumented refueling I've lost my track at fuel, but from the screenshots I was able to write down most of the Delta-Vs. They are not always the optimal ones but what I experienced in my mission... (from Kerbin orbit): around 25660 m/s. by ship type: RED: Mothership movements: 4500 m/s (for one launch but I used multiple launches) + 6030 m/s BLUE: Moon-orbit Module + Lander together: 7330 m/s (max. 2140 m/s at Laythe) GREEN: Lander: 12'300 m/s (max. 5500 m/s at Tylo) in details: 1. Kerbin launch to 100km orbit: ~4500 m/s 2. Jool intercept + corrections to put Mothership into orbit between Laythe and Vall: 2530 m/s 3. from Mothership to Laythe intercept: 250 m/s 4. Laythe 60km orbit: 940 m/s 5. Laythe landing: 800 m/s (from orbit to a landing path, then parachutes + braking) 6. Laythe ascent back to 60km orbit: not sure (I think at least 3000 m/s) 7. Laythe orbit to Mothership: ~950 m/s 8. from Mothership to Vall intercept: 240 m/s 9. Vall 74 km orbit: ~500 m/s 10. Vall landing: 1100 m/s 11. Vall ascent back to 74 km orbit: 1100 m/s 12. Vall orbit to Mothership: ~400 m/s 13. Mothership to Tylo high eccentric orbit for easy escape: ~400 m/s 14. from Mothership (high ecc. orbit) to low Tylo orbit (45km): 750 m/s 15. Tylo landing: 3100+ m/s (maybe 3300 is closer to reality) 16. Tylo ascent back to 45 km orbit (turning immediately): 2400 m/s 17. Tylo orbit to high eccentric orbit (to Mothership): 800 m/s 18. Mothership moving out of Tylo to a little higher Jool orbit: 100 m/s (the orbit around Tylo was highly eccentric so at the Apoapsis this was enough to leave Tylo orbit ) 19. from Mothership to Bop intercept: 200 m/s 20. Bop 30 km orbit: 600 m/s 21. Bop landing: 300 m/s 22. Bop ascent back to 30 km orbit: 180 m/s 23. Bop orbit to Mothership: 1100 m/s (braking at high speed meeting) 24. Mothership - Pol intercept: 150 m/s 25. Pol 18 km orbit: 150 m/s 26. Pol landing: 180 m/s 27. Pol ascent back to km 18 orbit: 150 m/s 28. Pol orbit to Mothership: 300 m/s 29. Mothership (without the large tanks) from Jool to Kerbin with Laythe assist and with bad maneuvering at Kerbin: ~ 3000 m/s I hope this will help when planning a huge mission like landing a Kerbal on all the moons of Jool and return in one mission!

dawg: Congratulations to you too, nice job! I like your landing gear solutions... That's fun to see how many solutions we found for landing there (and getting away). Yeah, I think leaving Laythe is harder than Tylo. On Tylo you can turn almost immediately after ascent and so you don't have to fight it's gravity for so much time, but in Laythe you have to go against gravity+atmosphere. Yeah, I landed "close" to the water but it was too far away for me too. Yeah, I missed the Vall anomaly on my mission. (Maybe next time! ) Hm, which parts of your ship landed on Tylo? That's not really clear... did you stage anything for braking from orbit to landing and at return? Yeah, I don't wonder it was too strong for Pol with TWR 38+... Good job you too, you are in the Hall of Fame from now!

Space Viking: Congratulations, nice job! Sure, the in-flight fuel line repair was executed by your Kerbals on an EVA, so that's not a problem. Nice assists at Duna, and I liked your lander solution for Laythe! And your Mk1 lander can with engines is also a pretty elegant solution. And it's good to see as somebody was going with different landers to different moons. Good job, you are in the Hall of Fame too!

Space Viking: wow, what a space train you built! Hopefully you will have enough torque or RCS fuel! So you built a different lander for all the moons? I'm curious how they will work! Yeah, the suborbital catch at Laythe was pretty annoying (I almost gave up) but not because of the atmosphere drag (it was not really felt that high) but finding the right timing when the Lander/Orbiter gets very close to each other at the same height... when I managed to put them at ~ 1km distance the Moon-orbiter was quickly there (turns very quickly with the large ASAS) and I had some minutes to do the dockings. It was exciting anyway!

Cool! Funny stuff!

I have made 8684 science points in a single mission to Jool where I landed on all the Moons, each with one Kerbal (EVA+surface sample) and all the science units, and took them back to Kerbin... : http://imgur.com/a/ZCaAu

There's a Challenge on this kind of mission, check that out! -> http://forum.kerbalspaceprogram.com/threads/57197-THE-ULTIMATE-JOOL-5-CHALLENGE-land-Kerbals-on-all-moons-and-return-in-one-big-misson

I have finished my JOOL-5 mission, too! Experiences: 1, the Lander Body was weak at returning orbit from Laythe. Big issue, almost ruined the mission! 2, Landing on Tylo is hard, but a little ascent ship with a lot of deltaV (3100+) can make it back to orbit easily. 3, Moon-orbit Module for bringing the lander from the Mothersip to orbit-deorbit was a No1 idea and worked pretty well, even for pushing the Main Section back to Kerbin. With the large ASAS it is VERY agile and with two nuclear engines it is very fuel efficient! RCS was used only for docking 2x150 was too much to bring... 4, For the Main Engines I used 7 orange tanks but there was no chance to decouple (for making as little part count as possible) ... next time it would be better if the empty tanks can be dropped away... 5, this mission was a huge challenge and needs previous experiences! ...and I have gained 8684 science points for this mission! pictures about getting home: http://imgur.com/a/ZCaAu#134 picture about my ship: ... ... and all the pictures about this huge mission:

Wow, ttnarg, very impressive design! And your additional landings on Eeloo, Dres and Ike are just unbelievable! o.O ttnarg, Congratulation, you have accomplished the JOOL-5 Grand Tour, with additional achievements, too! Question: did you go into orbit around Eeloo, Dres, Ike, or just landed with the help of the Space Tug and catched up with the Mothership? Hm, 14 Kerbals for the next mission? Let me count the bodies in the system... (make a challenge around it and invite me too! )

...and I have finished the last landing too! Now I only have to rearrange the ship, leave every unnecessary stuff behind and come home! here are the pictures: http://imgur.com/a/ZCaAu#119

Highlad: yeah, feel free to steal any idea from my design... (except the Laythe Lander: it's not capable of getting back to full orbit ) I'm curious what kind of twist do you mean! By the way I just put together one+six orange tanks without any decoupling or struds because I wanted to lower the part number as much as possible. But this way when the refueling arrived to Jool three of the tanks were already empty. But the Mothership doesn't really move (only some hundred m/s for orbit-changings between the moons), and I think I can bring home the Living Section+Science Units on the Moon-orbit Module alone so I don't need to bring the orange tanks back. So they really act like a refueling station only.
