Exploring Planetary Interiors: Observations, Models, and Experiments

Session ID#: 160596

Session Description:
Geophysical observations interpreted using quantitative models and experiments are the key to advancing our knowledge of the dynamics and interior structure of planetary bodies, including variations of density, fluid content, and temperature. The intent of the session is to promote discussions on the relationship between recent geophysical measurements from various planetary missions, new constraints on numerical and experimental studies, and the implication for interior structures and dynamic processes that involve interactions between materials from the crust to largely unexplored core-mantle boundary regions in deep planetary interiors. We welcome contributions of recent advances in planetary studies that incorporate various mission data and constraints, while providing a roadmap for future exploration of the Moon, Mars, and other extraterrestrial bodies
