Imagine how thick mercury atmosphere would be for human to survive there.
Anyway, I agree with what you just said, but I thought space was neither cold nor hot.
In any case, our solar system should be really hot, since the sun composes 90 % of it; since space has not atmosphere to filter the heat of the sun, it should be really hot out there, instead of cold.
Did the astronaut have a heating system or a cooling system installed in their suits?
Anyways, these are just things that I think about. Space being cold, or at least, our solar system...what happen to the heat waves from the sun before they get here? because they do get here, don't they? Do they turn cold while traveling all the way here and then turn back hot as they enter our atmosphere?
