This view of Saturn's second-largest moon, Rhea (1,528 kilometers, or 949
miles, across), shows some of the large craters that cover its surface.
There is a bright feature near the moon's right limb, possibly a large,
rayed crater or bright icy material exposed by internal processes.
The image was taken in visible light with the Cassini spacecraft narrow
angle camera on Sept. 26, 2004, at a distance of 7.1 million kilometers
(4.4 million miles) from Rhea and at a Sun-Rhea-spacecraft, or phase,
angle of 75 degrees. The image scale is 43 kilometers (27 miles) per
pixel. The image has been magnified by a factor of four and
contrast-enhanced to aid visibility.
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 Cassini orbiter and its two onboard
cameras were designed, developed and assembled at JPL. The imaging team
is based at the Space Science Institute, Boulder, Colo.
