ИСТИНА

The Luna-Glob landing zone is in the southern sub-polar region within the heavily cratered highlands. The main feature of this area is the southern portion of the rim of the South Pole-Aitken (SPA) basin [1, 2]. The major impact structures, basins, are the main sources of materials that form the megaregolith of the Moon [3], [4] and in the landing zone as well. In this region, numerous large craters (up to 100-120 km in diameter and a few kilometers deep) and high-standing massifs (several tens of kilometers across, 3-6 km high) form a very rough surface at tens of kilometers scale. The ancient terrains of pre-Nectarian and Nectarian ages prevail in the landing zone [1]. The units that compose the pre-Nectarian terrains are mostly related to the emplacement of ejecta of impact basins, especially SPA. However, during formation of the post-SPA basins, their ejecta that also were transported to large distances [5], [6], [7], [8] could be deposited within the Luna-Glob landing zone. In order to facilitate interpretation of the results of the Luna-Glob in-situ analyses, it is important to assess the potential contribution of ejecta of the lunar impact basins to the materials that may be encountered in the landing zone.
