If you had to design a vehicle that would travel from the Moon's surface to lunar orbit and back down again, then what would it look like? What kind of geometry or shape would it have? I'm thinking of a heavy-lift vehicle, which would be able to bring down mining equipment, and lift up ore. Would geometry really matter, since there would be no atmosphere to get in the way? Would a wide and flat pancake-shaped saucer be just as practical as a tall thin pencil-shaped rocket? Would a spherical shape be better, or perhaps an egg-shape? Or could it simply be an assembly of scaffolding without a single all-encompassing hull?
