The low illumination angle near the terminator makes visible the steep topography of craters on Rhea's battered surface.
This view is centered on 10 degrees north latitude, 128 degrees west longitude. North on Rhea (1,528 kilometers, 949 miles across) is up.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Nov. 16, 2007. The view was obtained at a distance of approximately 313,000 kilometers (195,000 miles) from Rhea and at a Sun-Rhea-spacecraft, or phase, angle of 128 degrees. Image scale is 2 kilometers (1 mile) per pixel.
The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. 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 and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colo.
