The Surface of Rhea

The surface of Rhea is typical of an icy moon. Rhea is as heavily cratered as Mimas on its leading hemisphere.

Rhea's trailing hemisphere is dominated by unusual white streaks extending for many kilometers over its surface. These streaks indicate that some geologically active processes on Rhea have been involved in resurfacing it. These active processes may include deposits of snow from fractures in the crust.
