The Cassini spacecraft views the far-off wispy canyons of Saturn's moon
Dione and sees an interesting dichotomy between the bright wisps and the
bright south polar region at the bottom.
The view looks toward the trailing hemisphere on Dione. North is up.
Dione's diameter is 1,126 kilometers (700 miles).
The image was taken with the Cassini spacecraft's narrow-angle camera on
Sept. 20, 2005, through a filter combination sensitive to polarized green
light. The image was acquired at a distance of approximately 2.1 million
kilometers (1.3 million miles) from Dione and at a Sun-Dione-spacecraft,
or phase, angle of 64 degrees. Resolution in the original image was 12
kilometers (8 miles) per pixel. The image has been magnified by a factor
of two to aid visibility.
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.
