If you need spin gravity, you put a pair of cans at the ends of a cable. Or truss if you are being extravagant.
Boosting at 1G the whole way would take a hell of a lot of fuel just for reaction mass, even with fusion. Producing enough 3He to do that with a crewed spacecraft would take a long, long time. Typically, you have to make 3H, tritium, and wait for that to decay at a half-life of 12 years.
- sjducb 4y agoThe old two spinning cans on a cable idea. When you drill into it you find that the stabilisation required for the cable is much heavier and more complex then a long rigid pole.
