Lunar crustal structure from high-res gravity, topography, and seismic data

该项目旨在提高我们对月球的认识，包括其表面过程、内部结构、地质过程的改变以及创造和演化。与地球不同，月球保留了太阳系历史上最长、最干净的地表地质记录。鉴于其复杂的撞击轰击和火山活动历史，月球地壳在密度（孔隙度和成分）上应该表现出很强的非均质性。该项目旨在通过分析重力恢复和内部实验室重力和航天器跟踪数据、月球轨道器激光高度计地形和阿波罗原位地震学数据，确定月球地壳密度和孔隙度的径向和横向非均质性。

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.
