If it's just in space, it'll be hard because you'll need basically some gravity at some point. I think you'd need orbital platforms that give you at least some partial gravity, if not 1G. If you're on Mars, even though the gravity is 38% of Earth's, just having that gravity would be enough. And if you could get under the surface into some of the lava tubes, where you have some protection above you from the radiation. So this is stuff to do on earth across thousands of humans.
