Thermal Control Systems: A Dual- Purpose Shield
Thermal control in spacecraft falls into two broad considences: passive and active. passive systems rely on materials and coatings with specific radiative and conductive intro maintaintain temperature balance. Active systems use heaters, colors, and fluid loops for precise regulation. Both type offer indererent micrometeoroid protection, but thee passive elements - thermal blankets, and surface coatings - are priy contributiors o trestance.
