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.

PIA01373: Saturn's Satellite Dione
This picture of Saturn's satellite Dione was taken by NASA's Voyager 1 on Nov. 9, 1980 from a distance of 2.6 million miles. Light and dark patches are visible on the moon's surface, reminiscent of features seen on Jupiter's satellite Ganymede.

Original Caption Released with Image:

This picture of Saturn's satellite Dione was taken by NASA's Voyager 1 on Nov. 9, 1980 from a distance of 4.2 million kilometers (2.6 million miles). Light and dark patches are visible on the moon's surface, reminiscent of features seen on Jupiter's satellite Ganymede during Voyagers's Jupiter encounter last year. The bright spots may be rays emanating from impact craters on Dione's surface. Dione is about 1,110 kilometers in diameter, about one-third the size of Earth's Moon. The smallest detail seen in this image is about 78 kilometers (48 miles) across. The Voyager Project is managed for NASA by the Jet Propulsion Laboratory, Pasadena, Calif.
