Habitability of Icy Worlds Workshop

Presenter: Patricia Beauchamp, NASA Jet Propulsion Laboratory
When: February 5, 2014 8AM PST

The primary objective of this workshop is to focus on the astrobiological potential of icy worlds in the outer solar system — including Europa, Ganymede, Enceladus, Titan, and beyond — with discussion on future research directions and spacecraft missions that can best assess that potential. The agenda for the workshop is organized around thematic sessions that address the potential habitability of the unique planetary environments of the outer solar system.
