Exploring the Lunar Surface in 3D Using Gravity and Topography

The three-dimensional structure of the Moon’s crust remains poorly constrained, limiting our understanding of what materials are present on the Moon, how they vary regionally, and what may have caused those variations. In this talk, I will present about my work using combined analysis of gravity and topography data to investigate the three-dimensional density structure of the lunar crust, focusing specifically on the Imbrium giant impact basin on the nearside. I will also talk about using independent satellite observations alongside my modeling results to interpret the geologic history of the Imbrium region.
