We are investigating the internal structure and evolution of the Moon. Our approach includes the analysis of gravity and laser altimetry data from the Clementine mission to characterize the Moon in a geophysical sense on the global and regional scales. We are also analyzing these data sets and using them as constraints on three-dimensional convection models that we are developing to address the Moon's early thermal evolution.

Clementine geophysical data products produced by our group at MIT and the Goddard Space Flight Center are available via anonymous ftp from the Geophysics Node of NASA's Planetary Data System (PDS) at Washington University, St. Louis.

These datasets, as well as geophysical analyses of the Moon based on them, are described in:
