Due to evolving government cybersecurity requirements, the Internet addresses (URLs) of five Discipline Nodes of the Planetary Data System (PDS) have changed.  The new URLs are:

Node:                                       URL is now…

Atmospheres                                    http://pds-atmospheres.nmsu.edu
Geosciences                                      http://pds-geosciences.wustl.edu
Planetary Plasma Interactions       http://pds-ppi.igpp.ucla.edu
Ring-Moon Systems                         http://pds-rings.seti.org
Small Bodies                                     https://pds-smallbodies.astro.umd.edu

The URLs for the Engineering and Management Nodes, and the Navigation and Ancillary Information Facility have not changed.

The PDS apologizes for any disruptions that these changes cause.
