[4.05] Modeling Lunar Dynamics

J. G. Williams, D. H. Boggs (Jet Propulsion Laboratory)

A precise model of lunar dynamics is needed to analyze the very accurate lunar laser ranges. The orbital dynamics accounts for multi-body gravitational interactions, relativistic effects, nonspherical gravity fields, and tides on Earth and Moon. The lunar rotational dynamics involves torques from the lunar gravity field, figure-figure torques, tidal distortion, tidal dissipation, dissipation at a fluid-core/solid-mantle boundary, and torques from that oblate boundary.
