现在日本正在进行名为月球工程探测器SELENE(SELenological andENgineering Explore)的月球探测计划的概念研究。SELENE由一个绕月轨道器、一个绕月中继卫星和一个实验月球着陆器组成,用以掌握在月球上实现基本软着陆的技术。本文介绍月球着陆器系统的概貌、任务剖面和飞行程序,还介绍了着陆器的关键技术,如自主躲避障碍的控制技术。 Japan is now conducting a concept study of a lunar exploration program called SELENE (SELenological and Engineering Explore). SELENE consists of a lunar orbiter, a lunar relay satellite and an experimental lunar lander to grasp the technology for achieving a basic soft landing on the moon. This article describes the lunar lander system overview, mission profiles and flight procedures, but also introduces the key technologies of landers, such as autonomous avoidance barriers control technology.
