The leading hemisphere of Dione displays linear grooves and subtle streaks
in this Cassini view.
Terrain visible here is on the moon's leading hemisphere. North on Dione
(1,126 kilometers, or 700 miles across) is up and rotated 17 degrees to
the right.
See PIA07688 for a similar false color
view.
The image was taken with the Cassini spacecraft narrow-angle camera on
Dec. 24, 2005 at a distance of approximately 597,000 kilometers (371,000
miles) from Dione and at a Sun-Dione-spacecraft, or phase, angle of 21
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.
