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

我们将通过使用遥感重力(GRAIL)和地形(LOLA)数据分析大型撞击盆地的近地表和深层结构，来完善我们对月球晚期吸积史的理解。我们还将通过研究受撞击园艺过程影响的地表样品的来源，特别是喷射物的就位和迁移，来增进我们对月球盆地形成时间和过程的了解。最后，通过使用数值模型，我们将估计撞击体的能量(和质量)以及评估盆地形成时的月球环境特征。

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.
