ABSTRACT
The gravity field of the Moon is a key quantity in lunar science. It substantially contributes to improve our knowledge about the mass distribution in the interior of the Moon, crustal properties, deep tectonic features, and the lunar evolution history (e.g., Andrews-Hanna et al. 2013; Wieczorek et al. 2013; Zuber et al. 2013b), especially when coupled with geologic mapping information (Wilhelms, Howard, and Wilshire 1979). Geophysical parameters, such as the selenopotential Love number k2, can be estimated together with the gravity field from satellite tracking data. Due to the lack of appropriate seismic data and other in situ surface investigations, these geophysical quantities act as critical constraints to determine the state of the lunar core (Goossens and Matsumoto (2008), Williams, Boggs, and Ratcliff 2009, Yan et al. 2013a, 2013b).
