Thermospheres, exospheres, ionospheres and magnetospheres are affected by the source regions at low altitudes and by their interaction with the solar wind. A variety of past and present missions are dedicated to analysis of such planetary environments. This wealth of data as well as increasingly sophisticated modeling capabilities have driven great advances over the last two decades in our understanding of the structure, variability, composition and dynamics of these environments. For example, we are starting to elucidate the complex two-way coupling between surfaces and surface-bound exospheres, between thermospheres and ionospheres, between photochemically-dominated collisional ionospheres and transport-dominated upper ionospheres, and between all these regions and the highly variable solar wind. We invite contributions concerning airless bodies such as Mercury (MESSENGER, BepiColombo), Earth’s moon (THEMIS-ARTEMIS, Kaguya, Chang’e, Chandrayaan), the Jovian moons (Galileo and Juno), Kuiper Belt Objects (New Horizons) and asteroids (Dawn) as well as bodies with substantial atmospheres such as Venus (PVO, VEx, Parker Solar Probe), Mars (MGS, MEx, MAVEN, InSight, EMM), Titan (Cassini), comets (Rosetta) and the giant planets (Cassini, Galileo, Juno). Both data-focused and modeling studies (and those which combine the two) are encouraged. Comparative studies are particularly welcome as are presentations on planned future missions which address the goal of understanding and characterizing planetary near-space environments. Both solicited and contributed talks will be included. </p>

By comparing the circulation of heavy ions in planetary magnetospheres with strong, weak, or no intrinsic magnetic fields, we can uncover the processes that govern plasma dynamics in response to various solar activities such as solar flares and CMEs. This session focuses on both observational and theoretical studies focusing on the sources, controlling factors of heavy ion flows, and their impacts in regulating plasma dynamics and magnetospheric structure, as well as new mission concepts that can measure the properties of heavy ion flows in the terrestrial and planetary environments. We invite researchers from planetary science as well as solar, magnetospheric, and ionospheric physics. We highly encourage comparative studies of different planetary environments throughout the solar system, including but not limited to the inner planets, outer planets, and their moons.</p>
