This session welcomes abstracts on the outer planets and Pluto systems, including their internal structures, atmospheres, magnetospheres, satellites and rings and coupling processes within those systems. A significant part of the session will be devoted to the Cassini-Huygens mission, including the Cassini Grand Finale Mission. Abstracts on observations from space and from the ground, modelling are also solicited. Supporting laboratory investigations and concepts for future space missions and Earth-based observations are also relevant to this session.
