PDS Information
Find a Node - Use these links to navigate to any of the 8 publicly accessible PDS Nodes.

This bar indicates that you are within the PDS enterprise which includes 6 science discipline nodes and 2 support nodes which are overseen by the Project Management Office at NASA's Goddard Space Flight Center (GSFC). Each node is led by an expert in the subject discipline, supported by an advisory group of other practitioners of that discipline, and subject to selection and approval under a regular NASA Research Announcement.

Original Caption Released with Image:

Dione shows Cassini some of the bright wispy streaks that cover much of the moon's trailing hemisphere. The streaks are thought to be deposits of icy material that has been extruded onto the moon's surface from the interior. Dione's diameter is 1,118 kilometers (695 miles) across.

The image was taken in visible light with the Cassini spacecraft narrow angle camera on Sept. 28, 2004, at a distance of 7.3 million kilometers (4.5 million miles) from Dione and at a Sun-Dione-spacecraft, or phase, angle of 79 degrees. The image scale is 44 kilometers (27 miles) per pixel. The image has been magnified by a factor of four 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 Cassini-Huygens 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.
