The Cassini spacecraft looks down, almost directly at the north pole of
Dione. The feature just left of the terminator at bottom is Janiculum
Dorsa, a long, roughly north-south trending ridge.
Lit terrain seen here is on the anti-Saturn and trailing sides of Dione
(1,126 kilometers, or 700 miles across).The image was taken with the
Cassini spacecraft narrow-angle camera on March 22, 2008 using a spectral
filter sensitive to wavelengths of ultraviolet light centered at 338
nanometers. The view was acquired at a distance of approximately 650,000
kilometers (404,000 miles) from Dione and at a Sun-Dione-spacecraft, or
phase, angle of 99 degrees. Image scale is 4 kilometers (2 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 operations center is based at the Space
Science Institute in Boulder, Colo.
