Extraordinary Enceladus

Session ID#: 159706

Session Description:
With the release of the 2023-2032 Decadal Survey Origins, Worlds, and Life, we now know that a return to Enceladus is a top priority of the planetary science and astrobiology communities. The reason why Enceladus is of such profound interest is the extraordinary science that it has provided on ocean world processes and the potential for life beyond Earth.

This long-standing session seeks to continue our discussions on all of the fascinating phenomena that make Enceladus so alluring. We encourage submissions on a wide range of topics that include (but are not limited to): Enceladus’s plume, its jets/curtains, surface geology and composition, tectonics, ocean chemistry, heat generation and transport processes, hydrothermal systems, analog studies, interior structure, thermal and geochemical evolution, formation and age, prebiotic chemistry, habitability, and the possible nature and signatures of life. Submissions on approaches/instruments for future missions are also encouraged.

We welcome a diversity of perspectives.
