This is the Endeavour. It's mostly just used for doing stupid crap, but it can land on the moon just fine. I've taken it for swings around mercury as well, but it cant land.
this is my "grasshopper" . It looks really insectoid. Its purpose is exploration of deimos and phobos from mars orbit. I am currently working on a challenge with it
Maybe not the prettiest ever, but it can lift so extreme Payloads and a lot of fuel to send them places too. Used variations to launch most of the parts for my space station.
