Atlas, seen here, is one of the two moons that ply the Roche Division -- the region between Saturn's A and F rings. Prometheus also orbits within this division.

This view looks toward flying-saucer-shaped Atlas (32 kilometers, or 20 miles across at its widest point) and the unilluminated side of the rings from about 37 degrees above the ringplane.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on March 9, 2008. The view was obtained at a distance of approximately 1.5 million kilometers (925,000 miles) from Atlas and at a Sun-Atlas-spacecraft, or phase, angle of 44 degrees. Image scale is 9 kilometers (6 miles) per pixel.
