The Landing Process of Mars Phoenix Lander

文章主要介绍了"凤凰号"火星着陆器的着陆过程、着陆点选择方法原则、巡航阶段工作任务,对进入(Entry)、下降(Descent)和着陆(Landing)即EDL阶段的蒙特卡罗分析结果和飞行器重建数值结果进行了总结比较。并对"凤凰号"相关的经验和教训进行了比较总结,这对中国未来的火星探测以及其他深空探测具有一定的借鉴作用。

This paper mainly described the process of Mars Phoenix lander on Mars, including the methods and principle of selecting the landing site, the task of cruise stage, and compared and summarised the results of Monte Carlo Dispersion Analysis and flight data reconstruction during the whole landing phrases which included enter phase, decent phase, and the last landing phase etc.. Finally, the experience with regard to Mars Phoenix was summarised,which had some reference value for future Mars exploration mission and other space exploration missions.
