Passive Thermal Control

Passive Thermal Control refers to technologies and designs that regulate temperature without using active systems like heaters or coolers. It utilizes materials and structures—such as insulation, radiators, thermal coatings, and strategic orientation—to manage heat flow naturally. These methods help keep spacecraft and equipment within safe temperature ranges by minimizing heat gain or loss, improving reliability and reducing energy consumption. Essentially, passive thermal control is about leveraging physics and smart design choices to maintain stable temperatures efficiently and dependably in space environments.
