Solar System

This giant mosaic reveals Saturn's icy moon Rhea in her full, crater-scarred glory. This view consists of 21 clear-filter images and is centered at 0.4 degrees south latitude, 171 degrees west longitude. The giant impact basin Tirawa is seen above and to the right of center. Tirawa, and the even larger basin Mamaldi to its southwest, are both covered in impact craters, indicating they are quite ancient. The bright, approximately 40-kilometer-wide (25-mile) ray crater seen in many Cassini views of Rhea is located on the right side of this mosaic (at 12 degrees south latitude, 111 degrees west longitude).
