Even though space is cold, it conducts so poorly that spacecraft would probably have more problems getting rid of heat than keeping heat, considering how isolated they are. [[User:Tharkon|Tharkon]] ([[User talk:Tharkon|talk]]) 16:43, 22 February 2019 (UTC)

:It actually has little to do with conduction; the heat radiates pretty effectively, especially as it gets "hotter" vs the surrounding radiation. [[Special:Contributions/172.69.69.124|172.69.69.124]] 17:35, 22 February 2019 (UTC)

::You're right, spacecraft are cooled by radiation. Yet it is far less effective than conductive/convective cooling by blowing the surrounding medium (water, air, whatever) over the hot parts. It's so much easier to cool things down here on Earth! Cooling problems is one of the reasons why nuclear reactors are not very popular in space, they need massive cooling systems.
