This project aims to improve our knowledge of the Moon, including its surface processes, interior structure, modification by geological processes and creation and evolution. The Moon preserves the longest and cleanest records of surface geology in the Solar System’s history, unlike the Earth. The lunar crust should exhibit strong heterogeneity in density (both porosity and composition) given its complex history of impact bombardment and volcanism. This project aims to determine radial and lateral heterogeneity in density and porosity within the Moon's crust, by analysing Gravity Recovery And Interior Laboratory gravity and spacecraft tracking data, Lunar Orbiter Laser Altimeter topography and in situ Apollo seismological data.

该项目旨在增进我们对月球的了解，包括月球表面过程、内部结构、地质过程的改变以及月球的形成和演变。与地球不同，月球保留了太阳系历史上最长和最干净的表面地质记录。月球地壳的密度（孔隙度和成分）应该表现出很强的不均匀性，因为它经历了复杂的撞击和火山活动。该项目旨在通过分析重力恢复和内部实验室的重力和航天器跟踪数据、月球轨道器激光高度计地形和现场阿波罗地震数据，确定月球地壳内密度和孔隙度的径向和横向不均匀性。
