Rhea enters Cassini's field of view and glides lazily across the scene as the spacecraft observes Saturn's restless atmosphere.
Rhea is 1,528 kilometers (949 miles) across.
This view looks toward the unilluminated side of the rings from less than a degree above the ringplane. The rings form a dark line across center and cast shadows onto the northern half of this view.
The image was taken with the Cassini spacecraft narrow-angle camera on Aug. 13, 2007 using a spectral filter sensitive to wavelengths of infrared light centered at 750 nanometers. The view was obtained at a distance of approximately 4.1 million kilometers (2.5 million miles) from Saturn. Image scale is 24 kilometers (15 miles) per pixel on Saturn and 21 kilometers (13 miles) per pixel on Rhea.
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 Cassini-Huygens mission for NASA's Science Mission Directorate, Washington, D.C. 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.
