Ziv, I added 5 images to the album that I hope will help with some of the numbers. The first two images (screenshot537 & screenshot539) were in Laythe orbit just before and during the Vall transfer. The Laythe orbit was eccentric (515x75) and the ejection was timed well so that the ejection and transfer only took 382 m/s. A mid-course correction of 15 or so m/s was made so that I was able to insert into another very elliptical orbit around Vall (1.93Mmx186km). The only image (screenshot570) that demonstrates the Vall orbit is during the post landing rendezvous and its from the lander's perspective, but it is about to dock, so they are in the same orbit. The Vall ejection burn was only 157 m/s (screenshot580) and this sent the ship out to a 105 Mm orbit over Jool. It was followed by a burn to raise the periapsis. The final orbit is shown in screenshot606. I also have .sfs files at each major milestone (opportunity for bad flying) that I can upload or email, they are only 1.74 MB zipped if you would like to inspect them. Thanks, Pete

Hello, I think this may qualify as a Jeb level entry. Details: - 0.25, career, full tech tree - Mods: Toolbar, MechJeb, TacFuelBalancer, Kerbal Alarm Clock - 3 launches, Main ship, Main lander, Tylo Lander, Tylo lander launch also topped up the fuel before departure - costs: - J-V-CM: 272,622 credits, 518T on pad - Laythe1: 55,038 credits, 7.45T on pad - Tylo1: 94,664 credits, 136T on pad - 94T fully assembled, fueled, ready to go Mission Plan: - Assemble ship in Kerbin orbit ~300km - Jool Transfer - Inside Jool SOI, reconfigure ship, dropping empty tank and engines. - Tylo lander and Tug, piloted by Jeb - Main ship with Tug and MultiLander - Jeb goes to Tylo by way of a Jool aerobrake - Main ship goes directly to Laythe, aerocapture - Jeb Lands on Tylo, waits till he is needed - Bill Lands on Laythe, goes for a swim, returns to ship - Ship goes on to Vall - Bob lands on Vall, returns to ship - Ship goes to high Jool Orbit out near Bop - Thompwin takes lander to Bop, lands, returns to ship - Lemwise takes lander to Pol, lands, takes off - Jeb leaves Tylo, switches to the tug, takes tug back to ship, refuels main ship - Lemwise takes lander back to ship - Main ship leaves Jool SOI, transfers back to Kerbin - Aerocapture at Kerbin - Lab and Hab return to KSC - Profit There are many more details... Thanks, Pete

I will uninstall the mod and start over, I was wasting too much fuel flying sloppy anyway. Thanks, Pete

Ziv, On the subject of mods/addons: Can the "For Science!" addon be approved for use on this challenge? ref: http://www.curse.com/ksp-mods/kerbal/220264-for-science Thanks, Pete

Immelman, Fantastic! My hat is off to you Sir. -Pete

Ziv, Thank you for the kind words. This was the 5th attempt, the other 4 ran out of fuel somewhere between Vall and Pol. I should post a progression of the refinements. The separate logistics vessels came around version 3 or 4. I asked myself "why am I dragging all this fuel in and out of orbit so many times?" I am working on a Jeb level entry that I would like to share, but if I dove right back in without a break my fiance would be less than thrilled. -Pete

Hello, I am submitting my latest mission for the minimalist Jool-5 Challenge. Vital Stats: Single launch Basic Lander Can, just Jeb this time. Mass on pad: 129T Mass in LKO: 66T Mods: MechJeb, KerbalAlarmClock, TACFuelBalancer, CrewManifest (irrelevant for this mission) Mission Details: Air breathing first stage Conventional second stage 2 LV-Ns for interplanetary transfer Air breathing Laythe booster Once in Jool SOI The engine nacelles were detached and renamed Logistics-A (L-A) and Logistics-B (L-. The main tank was dropped on a intercept path with Jool and L-A docked with the aft end of the main craft. L-B maneuvered for a Jool aerocapture with a final apoapsis outside of Tylo's greedy reach, where it circularized. The main craft maneuvered for a direct Laythe encounter and aerocapture. Once in Laythe orbit the lander, with Laythe booster stage, landed on Laythe. During the Laythe ascent the Laythe booster was left to fall back to Laythe. The lander docked with the main craft and proceeded to Tylo. From an highly elliptic ( pe of 40, ap near the edge of SOI) Tylo the lander and Tylo module undocked and circularized at 40km. The lander burned off the first stage of the tylo decent package (becoming suborbital) and then landed. During Tylo ascent the lander used what was left of the decent package as a booster. When the lander joined the main craft it was refueled and the lander surplus fuel tank was left in Tylo orbit while the main craft (L-A and Lander) went to Vall. Vall orbit and landing was achieved, the lander refueled from L-A and what was left in L-A was used to transfer to Pol. In Pol orbit the lander took all remaining fuel from L-A, landed on Pol and then departed Pol leaving L-A in Pol orbit. The lander then rendezvoused/docked with L-B and proceeded to Bop. At Bop our old friend was paid a visit and then The lander returned to L-B. L-B then took the lander to high Jool orbit to await the Kerbin transfer window. L-B and the lander returned to Kerbin and performed an aerocapture. Once in LKO the lander undocked and returned to KSC. http://imgur.com/a/GRrns#0 -Pete
