The Ultimate, solar version(vanilla)

Vanilla - no DLCs or mods.
Simple large grid ship that I designed for myself, has mostly everything you need to be a mobile base, while its just a little over 1000 blocks.
Its uranium/solar powered by reactors + batteries + the solar panels slowly charge batteries when standing still and in view of the sun.

About thrusters(ion and hydrogen) - with almost no cargo, I sucessfully lifted off from mars, jumped to earth and landed on earth without crashing, but when landing on earth thrusters barelly held the weight of the ship, so if going on earth or alien planet with cargo you will have to add some atmospheric thrusters.
