The Ring-Moon Systems Node of NASA's Planetary Data System is devoted to archiving, cataloging, and distributing scientific data sets relevant to planetary ring systems.

OPUS Data Search

OPUS - Our Data Search Tool

  • The OPUS API can be accessed directly. See instructions in the OPUS API Guide.
  • Supports surface searches for the planet, satellites and rings (e.g., latitudes & longitudes).

  • Uses comprehensive target lists for Cassini ISS & VIMS.

  • Provides numerous viewing, illumination, spacecraft and instrument constraints.

Enhanced Cassini Support

Visit our Enhanced Cassini Support page for links to:

  • January 2016. Calibrated ISS images for the Jupiter encounter now available.

  • downloadable tables of enhanced geometric metadata,

  • all geometric metadata files regenerated february, 2015.

  • preview products and the keys to their interpretation,

  • new or updated data user’s guides - CIRS, ISS, RSS, & UVIS,

  • PDS’s consolidated Cassini Archive Page.

New from JunoCam at Jupiter
Juno Jupiter's Main Ring
Main Ring - Credit MSSS/MC

Obtained when passing through the equatorial belt, this is a full spin image that captured Jupiter's ring. The optical depth of the ring is greatest at this geometry, which compensates for the challenging phase angle. This is a public release image. JunoCam Jupiter data will be available from the PDS Cartography and Imaging Sciences Node later this year.

More information on JunoCam can be found at the JunoCam web site.

ROSES 2017 Proposal Support
  • Our Research Proposal Support pages provide information and links to data for ROSES 2017 programs relevant to the Planetary Ring-Moon Systems Node. They also provide links to support pages for ROSES calls for previous years.
Ephemeris Tool Updates
  • The new Pluto Viewer and Pluto Ephemeris Generator tools are now available.

  • The Cassini ephemeris now in use is the final selection for the remainder of the Saturn tour.
  • The small moon S/2004 N 1 is now available in all the Neptune tools.
