Line-of-sight acceleration data obtained by the Lunar Prospector (LP) extended low-altitude mission were inverted to free-air gravity anomalies on the reference surface of the lunar nearside. High-resolution topography data obtained by the Clementine laser altimetry were used to convert the gravity anomalies to the Bouguer anomalies. Analysis of mass deficits of medium-sized craters and mascon basins suggested that the lunar lithosphere was already as thick as a few tens of kilometers when these features were formed.
