Icy Moon Rhea
This view of Saturn' moon Rhea was captured by the Cassini orbiter on January 17, 2007. It shows bright wispy lines which are believed to be fractures. These fractures can be seen cutting across darker areas which represent older terrain. The fractures are lighter because icy material is brought to the surface through the cracks.
