The plume of gas, water vapor and icy grains emanating from the south polar region of the Saturn’s icy moon Enceladus represents one of the major discoveries made during the Cassini mission. It significantly modifies the plasma environment in the vicinity of the moon producing a complicated system of multispecies and multistreaming plasmas. Models predict that the Enceladus plume yields a radially narrow and dense torus of water-group neutral atoms and molecules centered on Enceladu’s orbit. Charge exchange collisions replace a fraction of the corotating ions with the new, slow and cold ion population. The primary goal of this project is to explore analytically and numerically how this new plasma environment affects the charging of the dust emanating from Enceladus, how the spacecraft - plasma interactions influence the plasma and electric field measurements in the Enceladus torus, and whether the plasma-dust and dust-dust interactions are responsible for the magnetic field topology discovered by Cassini near the moon plume.
