Search for Farside Deep Moonquakes: Source Determination of Unlocated Deep Moonquakes with Apollo 17 Lunar Surface Gravimeter [#1766] We located deep moonquakes that were not unlocatable from the previous lunar seismic data set by using the Apollo 17 Lunar Surface Gravimeter as an additional seismometer.

Reorientation of the Moon Due to South Pole-Aitken Basin Ejecta [#1363] As a result of the massive global ejecta blanket produced by the South Pole-Aitken basin, the Moon experiences a major reorientation that places the impact basin near the South Pole where we observe it today.

Lunar Obliquity During a Cassini-State Transition [#1752] The obliquity values attained by the Moon, during a Cassini-state transition, depend sensitively upon the poorly known values of the degree two gravity field at that time. This transition is a key event in the retention of polar volatiles.
