Abstract

The geomorphological and geological analysis of the surface of three primary and ten secondary landing ellipses (15 × 30 km) for the Russian Luna-Glob automated scientific station (Luna-25) is presented. The earlier selected landing ellipses are found in the sector of 65°–85° S and 0°–60° E of the lunar southern hemisphere. The geological characteristics of the ellipse include the analysis of the surface age and the identification of the material sources. The analyses of water equivalent hydrogen concentration in the sector of landing and rock content on the surface are also carried out. The constraints, such as the surface inclination and the characteristic of the spacecraft’s flight path are used for prioritization of the ellipses from an engineering-technical perspective. According to the results of the study, landing ellipses 1, 3, 4, 6 and 8 are determined as high-priority, while ellipses 5, 7, 9, 10, 11, as well as B1 and B2 are found the least favorable.

Luna-Glob任务高优先着陆点的地质和地貌特征

摘要

俄罗斯Luna-Glob自动科学站（Luna-25）的三个主要和十个次要着陆椭圆（15×30 km）表面的地貌和地质分析） 被表达。较早选择的着陆椭圆出现在南半球的月球南纬65°–85°S和0°–60°E区域。椭圆的地质特征包括表面年龄的分析和物质来源的识别。还对着陆区的水当量氢浓度和地表岩石含量进行了分析。从工程技术的角度出发，使用诸如表面倾斜度和航天器飞行路径特性之类的约束条件来确定椭圆的优先级。根据研究结果，将着陆椭圆1、3、4、6和8确定为高优先级，而将椭圆5、7、9、10、11以及B1和B2确定为最低优先级。
