工程光学监测技术在火星探测中的应用

Engineering Optical Imaging Technique in Mars Exploration

在深空探测活动中,利用工程光学监测技术可以对探测器的工程状态进行直观、有效地监测,辅助地面系统确认探测器状态。利用监测相机对地球、月球、火星、小行星等天体进行成像,可有效提升公众对任务的认知度和参与度。结合国际深空探测任务,文章对"火星快车"、"好奇号"等火星探测活动中的工程监测任务及相机进行了分析,并对以"嫦娥二号"卫星为代表的中国深空探测活动中的工程监测子系统进行了探讨。围绕中国首次火星探测任务,进行工程监测任务设计,利用固定安装式、可分离式两种监测相机实现各监测任务,并对监测效果进行分析。文章的工作可应用于中国首次火星探测任务。

In the deep space exploration activities, engineering optical imaging technique can be used to observe the probe directly and effectively in order to assist the ground system to check the state of the probe. The public comprehension and participation in deep space exploration activities can be greatly enhanced by taking photos of planets such as Earth, Moon, Mars and small asteroids by the engineering cameras. In the paper, the engineering surveillance tasks and systems in Mars Express and MSL are analyzed, and the engineering cameras in CE-2 are discussed. Then based on the analysis of the deep space exploration projects at home and abroad, the engineering optical imaging mission in China’s first Mars exploration project was designed. Two kinds of camera were used to accomplish the imaging mission, i.e., the fixed camera and the separating camera. From the evaluation of the imaging task, one can find that the work of this paper can be applicable to China’s first Mars exploration project.
