The first time i managed to get into orbit around, i didn't have enought fule to land.
So, I decided to return to Kerbin.
I had no idea how to do it, so I did it by trial and error.
A small burn here and there.
No fule left, but my orbit was very close to Kerbin, so I fastforwarded until I was at the closest point to Kerbin and got a gravity assist from the Mun.
Then I got into a very exentric orbit around Kerbin with periapsis just touching the atmosphere.
8 hours later (irl at maximum fastforwarding), I landed at Kerbin.
My most boring mission, but somehow it felt good.
And no, I didn't sit by my computer wating the entire time.
