What are the characterisics of space vessels?

Answer 1

well, space vehicles do not need wings or the like because it has no need to stay up. The most efficient spaceship design is a cube with thrusters on each side, this way it can fly in any direction. Fire cannot exist in space, so thrusters that shoot out fire are useless. However, thrusters that have a contained form of "push" can exist, and are quite efficient. Space vessels need lots of oxygen to keep a human alive, and sometimes an artificial gravity creator. A space explosion has no flame at all. Since flame does not exist in space because of lack of oxygen, an explosion would simply be a pile of metal shot outwards. I hope this answered your question.
