火星探测器热环境模拟与试验技术探讨

为保证火星探测器的可靠运行，需要对其进行真空热试验和火星表面热环境模拟试验。文章通过对国外火星探测器热试验的调研，梳理出热试验所涉及的关键技术。并通过对行星际空间热环境和火星表面热环境特点的分析，结合国外相关热环境模拟设备的研制使用情况，探讨不同热环境的地面模拟方法，可为我国火星探测器热环境试验设备的研制及开展相关热试验提供技术参考。

The thermal environment simulation and test technology for Mars probe

For a Mars probe, the thermal tests in vacuum and Mars surface environment are required. This paper reviews the thermal tests for Mars probes in various countries and the key technologies which would provide a reference for the probe development in our country. The thermal environment characteristics of deep space and Mars surface are analyzed, and the simulation methods of different thermal environments are discussed. A technical guidance is provided for the manufacture of the ground thermal environment test equipment for Mars probe.
