This false-color picture of Saturn's moon Rhea from Cassini enhances
slight differences in natural color across the moon's face. The extreme
north and south latitudes have a notable difference in hue compared to
the mid-latitudes.
This view of Rhea is a composite of images taken using filters sensitive
to green (centered at 568 nanometers) and infrared light (two infrared
filters, centered at 752 and 930 nanometers) and has been processed to
accentuate subtle color differences.
The image was taken with the Cassini spacecraft narrow angle-camera on
Feb. 18, 2005, at a distance of approximately 890,000 kilometers (553,000
miles) from Rhea and at a Sun-Rhea-spacecraft, or phase, angle of 116
degrees. The image scale is 5 kilometers (3 miles) per pixel.
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 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.
