Holy crap. Do you have a link to the mission report for the first one? I'm curious to see how it went.

Right here.  It's the all-time low mass record holder, too.  It was done in version 1.1 by @Nefrums

FYI, the smallest number of engines used in a Jool 5 mission so far (without ISRU) is 3:  a Rapier, a Spark, and a Dawn.  With ISRU, it has been done with just 1 mammoth!

@sdj64 Wow! I don't know if I can do that well but I'll still attempt to design something decent.

@Cpt Kerbalkrunch Congratulations, you have completed the Jool 5 Challenge on Jeb's Level!  The mission actually seems fairly efficient, given the constraints of the heavy pod and lack of nuclear propulsion.  The swappable pod was an effective strategy for this mission profile, and I don't think anyone has done 5 kerbals and 3 per landing before. Your 1510 Science points puts you in second place!  ...Jeb's level is not very popular these days.

I look forward to your proposed Eve mission.  Given that you're using the same Mk1-2 pod for every landing, I might recommend you try The Ultimate Challenge - with Jool and Eve done, you'll have all the hard landings out of the way!

Sweet, thanks. The mission was a blast. I love the look of the Mk1-2, and the challenge of using it is always enjoyable. Finished my Eve ascent vehicle today, and I'm proud to say it works well. Now I just have to design the descent stage to get it on the surface in one piece. And then design a launch vehicle that can lift the entire monstrosity off of Kerbin and get it to Eve in the first place. God, I love this game. :)

Would it be allowed by the rules of this challenge to do this mission in a somewhat upscaled system? Say, 6.4x? Not sure if thats even possible with a reasonable part count, but i wanted to try that for quite some time now...

Yes, that would be cool to see.  As long as your rescale includes all of Jool's moons orbiting Jool in the same order and at least 1x their stock size (some rescales change Bop and Pol differently, for instance - just make sure they are not smaller than stock), it is allowed.

Mission report will be here:

It may take me a while to do it though, so i´ll post again if i´m done!

I plan to use a spaceX like reusable rocket & ISRU ground unit to cut down on cost. I recover both rocket and ISRU for 100% does it still count?

On Jeb's level, does science collected from Jool count (gravity surveys, dipping into the atmosphere, etc), or does it all need to be only from the moons? What about collected from in orbit around the moons? What about science earned from data in the science lab?

In addition, I also already have several relays in orbit near Jool. Would it be against the rules to use them or do they need to be terminated prior to the launch? I could see their usage being considered cheating since they would decrease the final weight of the ship. Also, speaking of relays, if I can't use those relays would it be okay to bring a small swarm of relays to leave behind after the mission?

Yes, science from Jool including its high and low orbit, and atmosphere, counts.  Moon orbit space science also counts.  Science earned from a lab does not count, and anyway you would have to land the lab because transmitting science does not count.

Since turning ComNet off entirely is allowed, you can use your relays.  You can also use any ore scans you have already performed, or send a scanning satellite separately ahead of the mission.

Awesome. Thanks.

What an interesting challenge, now i am looking forward to DOCKLESS JOOL 5 MISSION, WITHOUT NERVA (due to my impatient nature) and currently building tylo lander stage, the landings will be :

Tylo->Laythe->Vall->Bop->Pol

I'm working on my first Jool 5 currently. It's in career mode, single-launch Falcon Heavy-style with center booster recovery, no ISRU, no nuclear or ion engines, no more than 1 asparagus-booster pair per stage, level 2/3/Jeb will depend on how well my lander SAS works. I'll send some screenshots later tonight when I'm back at my pc.

I forgot to mention, my mod list includes: BetterBurnTime, FSHangerExtender, KerbalEngineerRedux, KerbalJointReinforcement, ModularFlightIntegrator, RealChute, Space Y (regular only, not extended, only for landing legs), and VenStockRevamp (visual enhacements and stock-balanced intermediate power engines and fuel tank shapes).

So whichever version that counts as is fine.

Forgot to ask: Can a kerbal land in a seat in a service bay, and does adjusting the seat position count against part-clipping?

Here's my 3rd level Jool-5 mission in the form a video. I hope it's enough, but I can make a more detailed image album if necessary. Flown in KSP 1.3

Mission info:

  • Single launch stock SSTO with full part recovery. No refueling or ISRU needed.
  • All moons have separate landers, and the Tylo lander uses an Ion Tug for transfers. Landers are packed in one long + one short Mk3 Cargo Bay.
  • Mothership separates from lifter in LKO and continues to the Joolian system. Straight transfer to Jool without gravity assists. 
  • All landers (except Laythe Jet) separate from mothership in Jool SOI. Laythe's gravity used to capture to Jool and transfer to the moons. 
  • Landers return to mothership in Laythe orbit. Straight transfer from Jool to Kerbin, where orbit is achieved by burning retrograde (~1.1 km/s) and aerocapture.
  • Once in circular LKO, mothership unites with lifter. Mothership has no RCS, so final docking is done with the lifter.
  • A crew of six Kerbals with one for each moon and one for Ion Tug. Four are in Mk2 Crew Cabin, one in the Jet and one in the Tug.
  • Ship cost: 411,089
  • Mothership delta-V in LKO after separating from the lifter: 4,353 m/s
