Going to Tylo and back using just 1 fuel tank! (no mining/refueling)

[hazard-ish]

For a recent reddit challenge, I pushed the boat out and went to Tylo and back using one a single fuel tank for the entire mission without any mining or refueling! This mission involved 4 major gravity assists and took a HUGE amount of planning to get right. For those that don't know, Tylo is the hardest place to get to and return from in the game, since it is the size of Kerbin with 80% the gravity and no atmosphere (unlike Laythe) which is why I chose it for my challenge!

This was th reddit challenge that I entered, keep in mind that 'hard mode' was to land on Eve. https://www.reddit.com/r/KerbalSpaceProgram/comments/42foxh/weekly_challenge_week_114_orange_efficiency_ii/

I've spent extra time with this video getting nice camera angles and picking good music to use to make the video more interesting to watch so please check it out! Enjoy!

Awesome!

That is so amazing.

OK come on. Fuel margins that tight can't be a coincidence. Was there any sort of "reserve" you could fall back on? (I.e. adding more jet engines, jettisoning the LV-N's earlier, different landing profile, etc.) 

I'm not criticizing the mission in any way shape or form. I have yet to land on tylo other than one time messing with hyper edit.

That was an amazing video. I've not watched a video showing such flight skills in a while.

Nope, I had only tested the mission up to the point where I could return to Tylo orbit so had no idea how much fuel was required to get back home. In fact, that return was initially going to be a test-run so that when I re-did the entire mission (being more efficient throughout), I would know how much I needed when I landed on Tylo - thankfully that first return attempt worked

Quick! Someone tell this to @Rune!

Very nice. I totally love that cockpit and the launch system.

Incredible, HOW did you figure out all the gravity assists & such?
