nope Ring-Moon Systems Node - NEWHORIZONS

Welcome to the Ring-Moon Systems Node’s New Horizons Information Page


Last updated: 4/17/2017

While all of the New Horizons data are available from the PDS Small Bodies Node (SBN), the Ring-Moon Systems Node maintains duplicate copies of all of the released LORRI and MVIC data.

  • Searches of both LORRI and MVIC data are supported in OPUS. The search parameter set for LORRI includes enhanced geometry parameters generated by the RMS Node.

For each mission phase prior to the Pluto encounter, for each instrument, the raw data is provided in a single volume NHaabb_1xxx, and the corresponding calibrated data is in a single volume, NHaabb_2xxx, where aa is the mission phase, bb is a two character instrument abbreviation, and xxx is the remainder of the volume number.

Mission phases are:

  • LA - Post Launch Cruise
  • JU - Jupiter Encounter
  • PC - Pluto Cruise
  • PE - Pluto Encounter

For the Pluto Encounter, because of the long transfer time from the spacecraft, data are being released incrementally. The spacecraft downloads are prioritized by content, not chronology. Consequently, subsequent releases may contain observations that preceded those in previous releases. As a result, the incremental data deliveries are not made as additional volumes (002,003,etc.). In stead each knew delivery is conprehensive and includes all previously delivered data products. Thus for calibrated LORRI data from the Pluto encounter, the volume identifier for each release will be NHLOPE_2001. The easiest way to distinguish between multiple volumes is to check the value of the VOLUME_VERSION_ID keyword in the file found at the root level of the volume.


The metadata provided in the original INDEX.TAB files is very limited. We have produced a single, expanded index file covering each LORRI and MVIC volume.

In addition we have generated indices of enhanced geometric metadata for each calibrated LORRI volume. We plan to do the same for each calibrated MVIC volume in the near future.

  • All of the data, and the enhanced metadata can be accessed via Access Data.

Key Documents

The information contained in the SOC Instrument Interface Control Document (ICED), and in the documents submitted for publication in Space Science Reviews (SR) in 2007, is crucial to understanding the data in this archive. As such, the producers of this archive have included the best possible versions of these documents in the DOCUMENT sub-directory of each volume.

As a minimum, users of the LORRI data should review the following documents:

  • AAREADME. Provides an overview of the data set.
  • ICED. Contains general information and details of the LORRI instrument and data.
  • LORRI SRThe LORRI article submitted to SR.

For information on the geometry data included in the labels and metadata, see the

Mark Showalter has assembled a table of all the LORRI Jupiter ring observations, including a brief description of the targeting and the science goals.
