| Session Description | With MESSENGER at Mercury, CASSINI at Saturn as well as other planetary missions that provide a wealth of information (e.g., VENUS EXPRESS, MARS EXPRESS, LUNAR RECONNAISSANCE ORBITER...) or are in preparation (MAVEN, BEPI COLOMBO...), it is timely to put into perspective the common knowledge that has been accumulated for many years about the only Earth's magnetosphere. This session is dedicated to analysis of the ionized environment of planets other than Earth or that of celestial bodies - including exoplanets - both for properties of their own and from a comparative viewpoint. As an example, in-situ measurements at Mercury reveal magnetic field signatures commonly observed at Earth such as Flux Transfer Events or Traveling Compression Regions together with a rich composition of the magnetotail plasma as a result of substantial supply from the planet surface. In-situ measurements at the Moon reveal a solar wind interaction far more complex than previously thought with a vast amount of ions expelled from the surface gaining access to the lunar wake. The interaction between Mars or Venus and the solar wind is similarly investigated by a variety of spacecrafts. At Saturn, in-situ and global measurements suggest that the kronian magnetosphere is subjected to dynamical reconfigurations and energetic particle injections comparable to those observed at Earth during substorms. As for Jupiter, the selection of the ESA JUICE mission stimulates a variety of modelling efforts and comparative studies of the interaction between the planet's magnetosphere and its satellites. The aim of the proposed session is to gather works based on both in-situ and global measurements and/or numerical simulations in diverse astrophysical contexts to progress toward a global picture of the dynamics of planetary plasma environments. |
