Description
The solar system includes a number of non-magnetic objects. These include comets, Venus, Mars and the moon, as well as the moons of Saturn, Jupiter and beyond. The plasma interaction depends on upstream conditions, whether that is the solar wind or a planetary magnetosphere, and whether the object itself has any atmosphere. Several space missions have explored these objects so far, with many carrying plasma and fields instrumentation, and have revealed some similarities and differences in the interactions. Processes such as ion pickup are the key to the cometary interaction but is also present in many other locations, and ionospheric processes are important when an atmosphere or exosphere is present. In all cases plasma interacting with the surface or atmosphere can cause escape and modification over time. In this talk we will review plasma measurements at non-magnetic objects from the various missions, and summarise information about the key processes including plasma escape at these objects.
