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.

This global map of Jupiter's moon Io – derived from images acquired during the 55th, 57th, 58th, and 60th close passes of the gas giant by NASA's Juno spacecraft – shows the volcanic activity and other surface changes detected by the JunoCam instrument.

Cyan ovals denote areas of new, faded, or shifted plume and/or volatile deposits. Yellow ovals denote areas of probable new lava flows. Comparing JunoCam images to Galileo and New Horizons data reveals at least 20 new dark deposits, likely fresh lava flows or dark silicate ash deposits. Of these, six appear to be intra-patera resurfacing, while 11 appear to be lava flows outside of paterae. Fourteen new diffuse deposits associated with volcanic centers were also found.
