Yeah thats an interesting question. I assume you mean, for example, the astronauts in the apollo missions? I believe it got very cold when they turned off power for everything in apolllo 13. I dont know, but i would think its an equilibrium that is reached between how much heat is produced inside the capsule (humans + electronics), and the amount of heat the capsule can radiate (mainly a function of its surface area, some material index value, and its temp). So perhaps in the case of apollo capsules the surface area of the capsule is large compared to heat output of the internals.Why does capsule in space with astronomers inside need to run heater constantly to keep temperature up? If there is no conductive medium in space, where is heat going?
