Step one, for any of this, is to build a "permanent" for real ship.
A Ship that you can point in a direction and go. A Ship with a rotating section for artificial gravity. A Ship with a multi mega watt power source A Ship with several smaller vehicles for going to and from a planet etc.
Shooting people up there in a tin can that will burn up or be turned into a hut just isn't viable. Take the time to do it correctly.
Step zero: find a trillion dollar budget.
