Development of Thermal Control Technology for Deep Space Exploration Spacecraft in China
Spacecraft thermal control technology has been crucial in securing the success of a series of deep space exploration missions,including China's Lunar Exploration Program(CLEP)Chang'e-1 to Chang'e-6 and its Mars exploration mission Tianwan-1.China has accumulated ad-vanced design experiences and overcame a series of significant technical challenges such as high-temperature heat dissipation and low-temperature survival in low-gravity and medium-vacuum en-vironments.This paper provides a comprehensive review of the system designs,technological in-novation,product development,and engineering practice of thermal control for deep space explo-ration spacecraft over the 20-year span of CLEP.Coverage includes the development of thermal environment models for planets,active and passive thermal control technologies,and thermal testing technologies,with detailed explanations of their respective technological characteristic sprinciple and application performance.Furthermore,based on the developmental needs and challenge for China's upcoming deep space exploration missions,some recommendations are pro-vided for advancing thermal control technologies tailored to future deep space exploration spacecraft.
