摘要:
选择合适的软着陆区域及规划合理的巡航路线是月球探测的基础工作。以位于月球背面南极—艾肯(South Pole-Aitken,SPA)盆地内的冯·卡门(Von Kármán)撞击坑作为研究区域,综合使用多因子分析评估了月球探测的着陆区域和巡航路线。评价体系主要包括能表征着陆安全性的撞击坑的密度、撞击坑的影响区域、整个区域的平整情况、部分区域的平整情况等因子和体现科学探索意义的区域垂直结构、岩石属性和(FeO+TiO2)含量等因子,其中科学探索的评估分析是在安全可行性的基础上进行的。结果表明:在多因子叠加分析的基础上可选择出A、B及C 3个着陆区,并通过科学研究因子分析出路线2及路线3为合适的巡航路线。本研究为月球探测器着陆和巡航路线的规划提供了科学依据,为后续的月球探测工作提供了技术支持。

Abstract:
Selecting the right soft landing area and planning a reasonable cruise route are the basic tasks of lunar exploration.In this paper,the Von Kármán crater in the Antarctic Aitken basin on the back of the moon is used as the study area,and multi-factor analysis is used to evaluate the landing area and cruise route of lunar exploration. The evaluation system mainly includes the factors such as the density of craters,the impact area of craters,the formation of the whole area and the formation of some special areas,as well as the factors of the vertical structure,rock properties and the content of(FeO + TiO2)which can reflect the significance of scientific exploration. And the evaluation of the scientific exploration is carried out on the basis of safety and feasibility. Based on the multi-factor superposition analysis,three landing zones A,B and C are selected,and the appropriate cruising route is analyzed. This study provides a scientific basis for the lunar probe landing and cruise route planning,and it also provides technical support for the subsequent lunar exploration.
