I was messing around in the VAB when I suddenly realized that a Kerbal strapped to a reaction wheel, solar panels, xenon and an ion engine had a ridiculous amount of delta-v, so I tested a lander and launch my ion-shuttle-transfer stage-lander-improvised heat shield- reentry vehicle into Kerbin orbit and sent it off on it's maiden voyage, to Moho
And so I present: Going to Moho and Back using only 2 fuel tanks :DDDDD
