Outer planets satellites are very diverse bodies. Ganymede is the only satellite that possesses an internal dynamo. Europa’s ocean has significant astrobiological potential and the ocean/rock interface might resemble the terrestrial sea floor. Titan is the only moon in the solar system with a dense atmosphere and the only place besides earth with stable liquids at its surface. Enceladus ejects water vapor and organics from its south pole. Io’s volcanoes bear a lot of similarities with those of Earth, but at much higher levels of activity and many of the satellites exhibit stunning variety in tectonic processes. This session will cover the atmospheres, surfaces and exchange processes with the interior of all the outer planets’ moons. The session welcomes abstracts describing observations, laboratory experiments and numerical simulations.
