Abstract The Indian Space Research Organization (ISRO) has planned to explore the possibility of soft-land the lander/rover on the highland area of the Moon. The rover mobility and interaction studies under the terrain condition of the Moon need a large quantity of lunar soil simulant. This study presents the development of a new novel lunar highland soil simulant (LSS-ISAC-1) by using natural terrain anorthosite rock fragments without the addition of any chemicals or other minerals, etc. This study presents the development of a new lunar highland soil simulant (LSS-ISAC-1) representing the lunar highland soils. The geotechnical properties such as particle size distribution, specific gravity, shear strength, compaction, and compressibility of the LSS-ISAC-1 have been determined and compared with the Apollo 16 lunar highland soil properties and other available highland simulants. The bulk chemistry and particle morphology of the simulant were identified by performing X-ray Fluorescence Spectrometer Tests (XRF) and scanning electron microscopy (SEM) analysis. The comparison shows that the bulk chemistry, mineralogy, and geotechnical properties of the LSS-ISAC-1 are representative of the Apollo 16 lunar highland soil and comparatively match with the lunar highland simulants.

一种新型月球高地土壤模拟物 (LSS-ISAC-1) 的开发及其适用于 CHANDRAYAAN 任务的岩土特性

摘要 印度空间研究组织（ISRO）计划探索着陆器/漫游车在月球高地地区软着陆的可能性。月球地形条件下的月球车移动性和相互作用研究需要大量的月球土壤模拟物。本研究介绍了一种新型月球高地土壤模拟物 (LSS-ISAC-1) 的开发，该研究使用天然地形斜长岩碎片，不添加任何化学品或其他矿物质等。 本研究介绍了一种新型月球高地土壤的开发模拟物（LSS-ISAC-1）代表月球高地土壤。土工特性，如粒度分布、比重、剪切强度、压实、LSS-ISAC-1 的可压缩性和压缩性已经确定，并与阿波罗 16 号月球高地土壤特性和其他可用的高地模拟物进行了比较。通过进行 X 射线荧光光谱仪测试 (XRF) 和扫描电子显微镜 (SEM) 分析，确定了模拟物的整体化学成分和颗粒形态。对比结果表明，LSS-ISAC-1的整体化学、矿物学和岩土特性代表了阿波罗16号月球高地土壤，与月球高地模拟物比较匹配。
