The structure and dynamics of each planetary magnetosphere in the inner solar system are driven by a unique set of factors including the nature of its magnetization, atmosphere-ionosphere coupling, and local solar wind parameters. This session welcomes submissions on the intrinsic magnetospheres of Mercury and Earth as well as the induced magnetospheres of Venus and Mars to provide a forum for discussion of recent data analysis and modeling efforts, including those related to spacecraft flybys. The session will focus on general magnetospheric processes including, but not limited to: solar wind-magnetosphere interactions, magnetosphere-ionosphere coupling, plasma acceleration and transport, magnetic reconnection, wave instabilities, magnetotail dynamics, and bow shock physics. We encourage magnetospheric studies on each of these planets, as well as comparative studies of magnetospheres throughout the solar system. We also encourage contributions from non-US missions to provide an international forum for discussion, collaboration, and advancement in these science topics.
