What is a heat source?
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:
- the Sun
- reflected sunlight from planets and moons
- heating by friction when traveling through an atmosphere or gas clouds,
and
- released heat from planets.
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.
