Formation and evolution of large impact basins on the Moo (A04)

我们将利用遥感重力（GRAIL）和地形（LOLA）数据分析大型撞击盆地的近地表和深层结构，从而完善我们对月球晚期吸积历史的理解。我们还将通过研究被研究的表面样品的起源来提高我们对月球盆地形成时间和过程的认识，这些样品受到撞击园艺过程的影响，特别是喷出物质的就位和迁移。最后，通过使用数值模型，我们将估算撞击物的能量（和质量），并评估盆地形成时月球环境的特征。

We will refine our understanding of the late accretion history of the Moon by analysing the near-surface and deep structure of large impact basins using remote sensing gravity (GRAIL) and topography (LOLA) data. We also will improve our knowledge of the timing and processes of lunar basin formation by studying the origin of studied surface samples, which are affected by the impact gardening process, specifically emplacement and migration of ejecta material. Finally, by using numerical models we will to estimate the energy (and mass) of the impactors as well as assess the character of the lunar environment at the time the basins formed.
