The Surface of Rhea
The surface of Rhea is like many icy moons. Rhea is heavily cratered (even if it doesn't look like it in this picture). In fact, Rhea is has an many craters as Mimas
, the "death star" moon.
It also appears to have unusual white streaks going for many kilometers over the surface. This may show that there is some activity on the surface, such as deposits of snow from cracks in the icy ground of Rhea.
