Cassini captures crescent Rhea
CASSINI PHOTO RELEASE
Posted: July 20, 2004
This view shows a heavily cratered surface, and thus it is most likely an ancient one. Many of the craters visible here have central peaks. Cassini soon will look for clues to help unlock the moon's geologic history. The spacecraft is slated to fly by Rhea at a distance of only 500 kilometres (311 miles) on November 26th, 2005.
The image was taken in visible light with the narrow angle camera on July 2nd, 2004, from a distance of about 990,000 kilometres (615,000 miles) from Rhea and at a Sun-Rhea-spacecraft, or phase, angle of about 109°. The image scale is 6 kilometres (4 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 Cassini-Huygens mission for NASA's Office of Space Science, Washington, D.C. The imaging team is based at the Space Science Institute, Boulder, Colorado.
