P13A:
Enceladus: Decade's Observance of a Habitable World II Posters


Session ID#: 7905

Session Description:
This year marks the 10th anniversary of the discovery of the geysering south polar terrain of Saturn's small icy moon, Enceladus, and ten years of routine observing and studying its activity from the Cassini spacecraft.  Over the course of the last decade, it has become increasingly clear that Enceladus' geysers erupt from a large, long-lived, sub-ice-shell liquid water reservoir, chemically suitable for the sustenance of biological processes and directly accessible to sampling and analysis.  And by the time this session is convened, two of the last 3 close, targetted flybys that Cassini will make of Enceladus will have been completed and the data available for presentation. In this  session, we will focus on the most recent observational, theoretical and modeling results on the chemistry, state and dynamics of Enceladus' geysers, the moon's thermal and interior state, geologic activity, as well as its astrobiological potential.
