Hi all This is my first challenge. I wanted to explore the Jool system more, and I figured this would be a good way to do it. It was very much 'seat of the pants' without any real testing before I set out. So, here is my entry. I went with 'form over function' with the design and I wasn't concerned with efficiency as I had plenty of delta-v to spare. I also took the opportunity to land at Duna and Mun on the way home - both unplanned - but the aerobraking nodes I used made it too tempting not to try. - Which game versions did you use? 24.2 64 bit - What mods did you use, if any? KW and B9 (I think I only used a decoupler from KW, everything else was stock) and Mechjeb installed for information. Some other mods were already installed but not used (IR, TAC Fuel Balancer etc.) - How many launches were needed to start your mission from Kerbal? One - How many refueling did you do during the mission, how much and where? All fuel taken with the craft. Lander and transfer stage docked and transferred fuel three times (over Tylo before and after landing, and again after Pol landing). - Did you bring a Living Quarter (Hitch-hiker's Storage) for the guys during the long journey? No. Jeb did it tough alone in his little tin can Mk1. - Did you bring additional stuff like satellites, rovers, etc? Two rovers to scout for a good landing spot. I only used one at Laythe - Share the delta-V information too, if you tracked it! Lander had approx. 6100 delta-v and was re-fuelled three times. Not sure how much delta-v the transfer stage used. Please note a couple of things: I may have bent the rules slightly with the intakes. They slightly overlap (clip) with each other. There are two intakes each on 6 cubic struts: one intake fixed to the top node, and one intake rotated 180 degrees and fixed to the bottom node. As I said, I went with form over function and so bent the rules a touch here because they looked really good mounted that way. The delta-v stats showing in Mechjeb at the start of the trip are not accurate because I had the engines on the lander pointing retrograde and Mechjeb counts those as pushing against the craft. Therefor the actual potential delta-v was much higher. I had a game crash as I landed at Laythe and had to reload And yes, I know how bad my manoeuvre nodes were. I wasn't trying to be efficient, I was just trying to prove the concept and the ability of the craft to make the trip So there you go. It was a fun trip and I think I will do it again with more planning and aim to complete it on 'Jeb' level. Matt
