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:

The large, dark oval spot in Neptune's atmosphere is just coming into view in this picture returned from the Voyager 2 spacecraft on June 30, 1989. The spacecraft was about 83 million kilometers (51.5 million miles) from Neptune. Voyager scientists are interested in the dark oval cloud system, a very large system similar to Jupiter's Great Red Spot. Contrast of the features in Neptune's atmosphere is similar to that obtained at Saturn at about this same distance and lighting, whereas the features are similar to those seen at Jupiter. The Jet Propulsion Laboratory manages the Voyager Project for NASA's Office of Space Science and Applications.
