Session Proposal: Geology and Geophysics of Active Satellites and Small Bodies (AGU25)

P017
Geology and Geophysics of Active Satellites and Small Bodies

Session ID#: 251528

Session Description:
This is a session of contributed and invited papers on the geology and geophysics of active or recently active satellites and dwarf planets, including small exoplanets. Research is progressing rapidly due to the stream of new spacecraft and Earth-based telescope data, including Keck and the Large Binocular Telescope Interferometer.  The James Webb Space Telescope has been returning data and Juno is orbiting Jupiter and observing the Galilean satellites.  Additionally, Europa Clipper and JUICE, exciting missions to the Jovian system, are in flight.  Papers are welcomed on processes that affect the interiors of individual bodies, including Ceres and Vesta, as well as the surface expressions they produce. Included are the effects and chronology of internal heating (tidal dissipation and radioactivity), structural evolution (e.g., differentiation), tides, and other geophysical and geological processes (e.g., volcanism, tectonics).
Index Terms:
