This infrared color image of Enceladus was obtained by the Cassini visual
infrared mapping spectrometer on March 9, 2005, when the Cassini
spacecraft was 9,145 kilometers (5,716 miles) away from Enceladus.
Enceladus shows substantial differences in composition or, more likely,
particle size on its surface. Redder areas correspond to larger grain
sizes, and appear to be correlated with craters and ridged regions. The
surface of Enceladus is nearly pure water ice; no other components have
been identified yet.
The middle of the image is located at the equator near a longitude of 210
degrees. The image is about 100 kilometers (63 miles) square. The image
shows the ratio of reflected light at 1.34 and 1.52 microns, wavelengths
that are not visible to the human eye.
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 visual and
infrared mapping spectrometer team is based at the University of Arizona,
Tucson.
