How and why do we control heat on a spacecraft?
A heat source is anything that can heat up a spacecraft.
Heat sources can be external (from outside the spacecraft) or internal (from inside the spacecraft). External heat sources include:
Internal heat is often generated by the craft's propulsion or electrical systems. If a craft has parts that move against each other, friction can provide heating as well.
