月球南极探测着陆区选址方法

Landing Site Selection Method of Lunar South Pole Region

月球南极极区丰富的资源和光照条件,尤其是潜在的水冰,使其成为当前各国开展探测活动的一大热点。由于南极地区地形崎岖、光照变化迅速的特点,使得探测任务着陆区的选址至关重要。选址结果直接决定了探测任务的成败,也是整体方案过程中各分系统开展设计的重要依据。围绕月球南极探测着陆区选址,结合月球和太阳星历的几何关系、月球南极地形和光照特点,给出了选址的影响因素及约束,提出了从工程角度考虑选址的方法,通过不同分辨率的数据源,利用先粗筛后精筛的策略确定优选着陆区。最后,通过算例初步给出了5个区域(Haworth北部、Shoemaker东北部和Shackleton西北部、西部及东南部),可为中国未来月球探测任务设计工作提供参考。

Landing site selection is an important part of the design of an exploration mission.The correctness of site selection result directly determines whether the detector can successfully complete the mission,and also determines the important basis for the design of each sub-system in the program design process.In this paper,the site selection method of the lunar south pole exploration landing area was introduced,the topography and illumination characteristics of the lunar south pole were analyzed,the principle of site selection was formulated,the influencing factors and constraints of site selection were analyzed in detail,and introduces the engineering the site selection method using coarse-to-precise strategy,combined with the site selection results,and 5 landing sites were selected initially,which will provide reference for the design of future lunar exploration missions.
