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.

On July 23, 1989, the Voyager 2 spacecraft took this picture of Neptune through a clear filter on its narrow-angle camera. The image on the right has a latitude and longitude grid added for reference. Neptune's Great Dark Spot is visible on the left limb of the planet at about 22.5 degrees south latitude. In previous photographs, less detail was visible; now additional structure associated with the dark spot has become apparent. The jagged right edge of the large spot is real and is probably caused by cloud motion. Voyager 2 was about 47 million kilometers (29 million miles) from Neptune when this picture was taken. The smaller dark spot in the southern dark band is visible on the lower right with a small, light circle at its center. The Jet Propulsion Laboratory manages the Voyager Project for NASA's Office of Space Science and Applications.
