Enceladus: An Ocean World Odyssey
Session ID#: 249971
Session Description:
Saturn’s moon Enceladus is a geologically active and habitable ocean world. Enceladus offers fresh opportunities for advancing our understanding of planetary processes and searching for signatures of potential life. The most accessible ocean material beyond Earth erupts from the internal plumbing system of Enceladus, forming a plume that modifies the space environment at Saturn.This is the 20th consecutive year of this session, attesting to the phenomenal enthusiasm of our community. You won’t want to miss this one! We welcome the community to submit contributions diving into diverse ranges of phenomena including but not limited to: cryovolcanism, ice fracturing and other tectonic processes, ocean circulation, water-rock reactions, tidal heating, organic chemistry, life detection approaches, Enceladus’s formation, history, and internal structure, and cross comparisons with other ocean worlds including Earth and Europa. Observational, theoretical, laboratory, and field analogue investigations are all welcome.
