Spacecraft have a heat buildup problem; the electronic systems and such they contain generate heat, which is its own engineering challenge to get that heat dumped out into space. So they can’t take on too much heat from solar radiation or they’ll just fry up. Thus, they must be made to reflect that radiation.

Gold is exceptionally good at reflecting solar radiation, much better than any other substance. Lots of materials wil lreflect visible light, but as Squink points out gold’s especially effective at reflecting infrared. Gold is also more or less inert, very dense, and will last forever.

The gold is very efficient at reflecting away solar radiation, and so keeps the electronics inside from overheating.

Satellites are covered in golden foil. It is used for heat loss in thermal radiation

It’s not the color, it’s the material.

It used for gives production from over heat and cold because the space environment is lies only too category too heat and cold.
