This Cassini image shows the night side of Saturn's moon Dione, dimly lit
by "Saturnshine": that is, reflected light from the planet lying off to
the left in Cassini's field of view when this image was taken. Dione is
1,118 kilometers (695 miles) across.
The image was taken in visible green light with the Cassini spacecraft
narrow-angle camera on Feb. 18, 2005, at a distance of approximately 1.3
million kilometers (808,000 miles) from Dione and at a
Sun-Dione-spacecraft, or phase, angle of 118 degrees. The image scale is
8 kilometers (5 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.
