摘　　要：对中国第一颗火星探测器的功能与组成以及超远距离通信技术,深空探测自主姿态确定与控制技术,火星探测器热控制技术,火星探测器超低温适应等关键技术进行了分析,并提出了关键技术的解决途径,结合工程阶段的技术状态,论述了中国火星探测器的设计特点,对该探测器的研制以及后续相关型号任务的研制和生产具有良好的参考价值。In this paper, the function and design as well as the key technologies （ultra-long-range communication technology, deep space exploration attitude determination and control technology, thermal control technology etc.） of China＇s first Mars probe are analyzed. The solutions of the key technologies are given after the analysis, and then the design features are summarized. Finally, the whole satellite of YH-1 has undergone tests under various experimental circumstances, including： vibration, noise, solar array deployment, illumination, leak detection, vacuum thermal testing and sophisticated power testing, etc. In all these tests, YH-1 behaves normally. This paper can provide a good reference for the following tasks related to the development and production of the probe and following missions.
