The Surface of Dione
The surface of Dione does not have many craters, which is an indication of changes to the surface in the past. Instead it has wispy white streaks similar to those found on
Rhea extending for many kilometers over the entire surface. These is a further indication that there may have been active processes within Dione in the distant past.
