  Cassini captures Saturn's moon Rhea at crescent phase, a view never visible from Earth. Near the terminator, a few of Rhea's many craters show up in sharp relief.

With a diameter of 949 miles (1527 km) Rhea is Saturn's second-largest moon.

This view looks toward the leading hemisphere of Rhea. North on Rhea is up and rotated 12 degrees to the right.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Nov. 6, 2012. The view was obtained at a distance of approximately 1.2 million miles (1.8 million kilometers) from Rhea and at a Sun-Rhea-spacecraft, or phase, angle of 129 degrees. Image scale is 5 miles (7 kilometers) per pixel. Scale in the original image was 7 miles (11 kilometers) per pixel. The image was magnified by a factor of 1.5 to enhance the visibility of surface features.

The Cassini Solstice 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.
