  A small crescent of the moon Rhea is dwarfed by the larger crescent of Saturn.

Rhea (1528 kilometers, 949 miles across) can be seen in the upper right of the image. This view looks toward the southern, unilluminated side of the rings from about 3 degrees below the ringplane.

The image was taken in visible red light with the Cassini spacecraft wide-angle camera on July 15, 2010. The view was acquired at a distance of approximately 2.6 million kilometers (1.6 million miles) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 98 degrees. Image scale is 153 kilometers (95 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.
