The Cassini spacecraft views the "wisps" on the surface of the Saturnian
moon, Dione, looking from afar much the way they looked to the Voyager
cameras years ago. These linea cover the trailing hemisphere of the moon.
Cassini high resolution images revealed these bright features to be
geologically young fractures exposing the icy surface of the moon. (See
PIA07638).
North on Dione (1,123 kilometers, or 698 miles across) is up in this image.
The image was taken in visible light with the Cassini spacecraft
narrow-angle camera on Oct. 30, 2008 at a distance of approximately
858,000 kilometers (533,000 miles) from Dione and at a
Sun-Dione-spacecraft, or phase, angle of 61 degrees. Image scale is 5
kilometers (3 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.
