[QUOTE="sophiecentaur, post: 6532570, member: 199289"] Nor really. At such low speeds you will have no lift in the thin atmosphere and would be plummeting, gaining loads of KE again. If you use braking then whatever is slowing you down has to be dissipating a lot of energy and there's very little cooling available in a near vacuum. I have not done the sums ever but I think we can safely say that it would have been tried long ago for re-entering Earth if it were remotely practical. I suppose that a truly massive parachute might be an option. The cost would not be a problem in our new scenario, though. [/QUOTE]
