嫦娥三号 (CE-3) 航天器于 2013 年 12 月成功降落在月球上最年轻的母表面之一。CE-3 搭载的玉兔号月球车配备了雷达系统，可以以前所未有的细节揭示地下结构，这将有助于了解月球的区域和全球演化历史。基于区域地质学、陨石坑缩放和形态学研究，我们利用高分辨率轨道和现场图像数据量化了着陆点的地下结构。在着陆点地下识别出三层月球风化层、两层玄武岩单元和一层喷射物沉积物，并根据图像数据推断出它们的厚度。这些结果可以为CE-3雷达数据的持续解释提供重要参考。使用CE-3原位雷达观测验证我们的理论地下结构的能力将改进使用陨石坑形态和缩放来量化月球地下结构的方法。
The Chang’e-3 (CE-3) spacecraft successfully landed on one of the youngest mare surfaces on the Moon in December 2013. The Yutu rover carried by CE-3 was equipped with a radar system that could reveal subsurface structures in unprecedented details, which would facilitate understanding regional and global evolutionary history of the Moon. Based on regional geology, cratering scaling, and morphological study, here we quantify the subsurface structures of the landing site using high-resolution orbital and in-situ imagery data. Three layers of lunar regolith, two layers of basalt units, and one layer of ejecta deposits are recognized at the subsurface of the landing site, and their thicknesses are deduced based on the imagery data. These results could serve as essential references for the on-going interpretation of the CE-3 radar data. The ability to validate our theoretical subsurface structure using CE-3 in-situ radar observations will improve the methods for quantifying lunar subsurface structure using crater morphologies and scaling.
