Sierra Space has extensive experience in spacecraft thermal control. Our portfolio includes thermal louvers that draw from decades of NASA/JPL heritage and are currently supporting several interplanetary spacecraft and heat switches, which for years reliably controlled the main battery temperature on the Mars Exploration Rovers Spirit and Opportunity. Both technologies are considered passive approaches that require no externally supplied power to operate, allowing valuable spacecraft power to be reserved for other needs.
Sierra Space’s Passive Thermal Control Heat Switch is a device for controlling the temperature of electronics and instrumentation on satellites and spacecraft. These devices are part of our family of tools for spacecraft thermal control. They reduce spacecraft power requirements while providing improved control and better reliability at a lower cost than conventional thermal control schemes.
Sierra Space’s Thin Plate Heat Switch devices passively control the temperature of electronics and instrumentation on satellites and spacecraft. These devices are part of our family of tools for spacecraft thermal control. They can potentially reduce spacecraft power requirements while providing improved control and better reliability at a lower cost than conventional thermal controls.
