Cassini caught this glimpse of Saturn's second largest moon, 1,528
kilometer (949 mile) wide Rhea on Aug. 16, 2004. Notable in the image is
a brightening near the terminator.
The image was taken in visible light with the Cassini spacecraft narrow
angle camera at a distance of 8.5 million kilometers (5.3 million miles)
from Rhea and at a Sun-Rhea-spacecraft, or phase, angle of 86 degrees.
The image scale is 51 kilometers (32 miles) per pixel. The image has been
enhanced and 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.
