I have read that astronauts from Apollo 13 got very low temperatures for some time, due to no sunlight and no energy to heat them. But, if the space suits are good insulators, why it seemed not being much of a help this time? Isn´t the body heat enough?, or the suit also needs energy to deal properly with cold?

The spacesuits were rubberized and not able to breath. Had the astronauts worn them their perspiration would have be trapped inside the suits. The dampness would have resulted in a worse condition then not wearing the spacesuits at all.

I don´t know if I got it. Does it means that one needs energy to heat the spacesuit if it is used in constant shadow?

Well, there's the metabolic heat source and waste heat from the backpack systems heating it up. An empty inert suit would certainly cool down. It's a matter of whether the heat loss is more than the heat generated. I believe that the Shuttle astronauts report getting uncomfortably cold if they rest on the night side of earth, but Apollo astronauts never stayed that long in shadow. |
