Welcome To Rhea: Impact Central
This view of the trailing hemisphere of Saturn's moon Rhea shows the region's bright wispy markings, but also shows off the moon's craters in great detail. Of particular interest to imaging scientists is the distribution and orientation of the many craters with polygonal rims. These are craters with rough, angular shapes, rather than smooth, circular ones. Rhea is 1,528 kilometers (949 miles) across. This image was taken in visible light with the Cassini spacecraft narrow angle camera on Jan. 16, 2005, at a distance of approximately 500,000 kilometers (311,000 miles) from Rhea and at a Sun-Rhea-spacecraft, or phase, angle of 35 degrees. Resolution in the original image was about 3 kilometers (2 miles) per pixel. The image has been rotated so that north on Rhea is up. Contrast was enhanced and the image was magnified by a factor of two to aid visibility.

Within the shadows, bright bands represent areas where the ring material is less dense, while dark strips and wave patterns reveal areas of denser material.
