Hi.
So I was returning from a Mun landing, and I must have hit shift or z accidentally while in map view, because after I closed map view, I saw that my engine was thrusting and that 400 m/s of dV was gone, and I was on a collision course with the Mun. I managed to put the craft back into orbit, but by then I only had ~700 m/s of dV left, which is not enough to return from the Mun. However, apparently it would only take me ~250 m/s of dV to transfer to Minmus, and from there I could do some gravity assists and burns to try and return back to Kerbin. I tried messing around with manuever nodes, and got an encounter with Minmus, but I was unable to get a gravity assist that could lower my PE a meaningful amount. How can I get an gravity assist that will help lower my PE enough that I'll actually be able to make it with the remaining fuel (or a totally different way to make it back that does not involve the cheat menu)?e
Thanks! For reference, my craft is in a 80 by 80 Mun orbit with about 7 degrees inclination.
