Sketch of Saturn, Tethys and Dione

The plasma tori of the two satellites are approximated in blue for Tethys (indicating lower energy plasma) and green for Dione (indicating higher energy plasma).

The orbit of Cassini is shown in black with red lines showing the positions of observed inward plasma injections. Butterfly electron pitch-angle distributions consistent with outward plasma flow are observed throughout the regions in between the inward injections.
