Abstract
The Lunar gravity field is determined from the tracking data of previous missions to the Moon with the 1998-99 Lunar Prospector (LP) mission being the major contributor. LP provided the first measurement of the gravity field in a low polar circular orbit giving complete coverage at high resolution for the entire lunar nearside. However, since there is no direct measurement of the lunar farside from LP or any other mission, gravity details for the farside gravity are greatly limited. Even so, it has become apparent that there are mascons on the farside of the Moon together with the newly identified mascohs in the LP data for the lunar nearside. The extended mission low altitude data (at times less than 10 km above the surface) has gravity information for the nearside to nearly degree and order 180. The 100th-degree lunar gravity models (LP100Jand LP100K) extract most of the information from the nominal 100-km altitude. A 165th degree model LP165P attempts to model the extended mission data with some but limited success.
