  Beyond the ansa of Saturn's rings, a crescent Rhea completes this ring-and-moon composition.

Rhea (1528 kilometers, 949 miles across) is near the middle of the bottom of the image. This view looks toward the northern, sunlit side of the rings from about 4 degrees above the ringplane.

The image was taken in visible light with the Cassini spacecraft wide-angle camera on Aug. 24, 2009. The view was obtained at a distance of approximately 1.6 million kilometers (994,000 miles) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 137 degrees. Image scale is 95 kilometers (59 miles) per pixel.

The Cassini Equinox Mission is a joint United States and European endeavor. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, D.C. The Cassini orbiter was designed, developed and assembled at JPL. The imaging team consists of scientists from the US, England, France, and Germany. The imaging operations center and team lead (Dr. C. Porco) are based at the Space Science Institute in Boulder, Colo.
