Re: Space travel by humans is not possible now

This Mars talk is mostly hypothetical, as a Mars mission is very

But if we take examples from Earth, Eskimoes could achieve fairly
reasonable temperatures within iglooes...where the temperatures were
as bad as - 50C. Now, a hypothetical Mars dvelling might be dug down a
bit, say halfway down, then the remainder covered with material taken
from the surrounding ground.

It sounds reasonable that such a low tech approach can achieve pretty
reasonable degree of protection from the environment. Then add in
hightech equipment to close the loop.


Yes, underground the temperature can be higher. But -80 to -100
are normal night time temperatures.

And the problem is that this approach doesn't work with *vehicles*
