月球南极探测着陆工程选址建议

Proposals for Sites Selection of Soft Landing on Lunar South Polar Region

  • 摘要: 目前人类已经成功实现了对月球中纬度地区的着陆探测,而对于月球极区的探测,尤其是在科学和工程上普遍认为探测意义重大的南极区域,尚属空白。对月球南极极区环境,包括温度、地形地貌、光照和测控等条件进行了初步分析。针对月球南极区域具有温度低、地形地貌复杂(撞击坑多、坡度较大)、太阳高度角低(南极点的太阳高度角在 ± 1.54°之间变化)且遮挡情况严重、对地不可见弧段较长等特点,提出了工程着陆选址的原则。着陆探测任务首先要选取合适的着陆区,不仅要满足科学目标需求,而且还应具备工程可实现性,尽可能地保证着陆安全,经过对撞击坑周围环境的比较讨论分析初步选择了4个区域(沙克尔顿撞击坑、霍沃思撞击坑、舒梅克撞击坑和坎布斯撞击坑),10个着陆点,可为未来工程实现提供参考。

     

    Abstract: Human-beings have achieved lunar soft-landing on the surface of mid or low latitude regions. However no one has realized the exploration mission for the polar regions, especially for the south polar region, which attracts most attention because of its high scientific and technological value. In this article, the environment of lunar south polar region is analyzed, including the temperature condition, topography, illumination condition and earth visibility. Different from the regions with mid or low latitude, the temperature for lunar south polar region is very low(from 100 K to 160 K). The topography is more complicated (more craters, greater slope, scattered stones). The sun elevation angle is very small(which is between−1.54° and 1.54° for the south pole) and there are more shadows because of the high mountains. And there are long durations of earth-invisibility. All these environment conditions will much affect the lunar south polar region soft landing mission. According to the analysis of lunar south polar environment, some engineering suggestions for the lunar south polar region soft landing mission are proposed, which will provide reference for the implement of engineering .
