Mars terraforming is hard and will require serious tech. At a minimum you would need to crash asteroids/comets rich in water and nitrogen into it. So I wouldn't really worry about the 7% atmospheric pressure limit, it's not going to be a constraint that matters.
- est31 7y agoCan you tell me about the long term problems that colonizing asteroids entails? It feels to me that colonizing the surface of planets is very wasteful: the entire core is rich of various elements which you could access if you disassembled the planet (there is no other way than disassembling it).
