Sliding Away... (natural colors; credits: NASA)

Caption NASA:"The Cassini Spacecraft looks toward Rhea's cratered, icy landscape with the dark line of Saturn's Ring-Plane and the Planet's murky atmosphere as a background.
Rhea is Saturn's second-largest moon, at about 1528 Km (approx. 949 miles) across.
This view looks toward the unilluminated side of the Rings from less than 1° above the Ring-Plane.

Images taken using red, green and blue spectral filters were combined to create this natural color view. The images were acquired with the Cassini spacecraft narrow-angle camera on July 17, 2007 at a distance of approx. 1,2 MKM (such as about 770.000 miles) from Rhea.
Image scale is roughly 7 Km (about 4,5 miles) per pixel"
