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.

NASA's Juno spacecraft captured these images showing surface changes at Nusku Patera (center in each sub-figure) on Jupiter's moon Io.

A red ring formed around Nusku Patera in the two months between the spacecraft's 58th flyby on Feb. 3, 2024, and its 60th on April 9, 2024. The ring obscures some nearby features like Creidne Patera. This ring, 683 miles (1,100 kilometers) wide is likely from a Pele-type plume rich in sulfur. Similar transient red rings were observed by NASA's Galileo mission around Grian Patera and Surt and were associated with intense but short-lived thermal "outburst" eruptions.
