Cassini caught a hint of Rhea's heavily cratered surface as it sped
rapidly away from the moon on its first orbit of Saturn. There is a
noticeable brightening near the left limb of the icy moon. Cassini will
have its first flyby of Rhea in November 2005.
The image was taken in visible light with the Cassini spacecraft narrow
angle camera on July 20, 2004, from a distance of 5.9 million kilometers
(3.6 million miles) from Rhea, and at a Sun-Rhea-spacecraft, or phase
angle of 91 degrees. The image scale is 35 kilometers (22 miles) per
pixel. The image has been magnified by a factor of four 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 Office of Space
Science, 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.
