NEAR Data Archive and Data Analysis Program

Archive History

Archival data from all instruments of the NEAR mission underwent an external peer review, organized by PDS Small Bodies Node, on August 15-16, 2001. Many liens from the peer review were corrected by the NEAR project. The final version of the data, on 539 CDROMs, was shipped to PDS Central Node on September 24 and October 2. Because of the large volume of final data, the CDROMs were converted to DVDs. As of January 4, 2002, all final data for the NEAR Data Archive are available online at the Small Bodies Node. Links to the archival data are provided below. A limited set of final data is available at the Central Node. The final data are being internally reviewed by SBN to assess the resolution of the liens from the external peer reviewers.

The Online Archive

The NEAR Data Archive held at the Small Bodies Node is the most complete inventory of the final, PDS-formatted, mission data that is available online.

• Go to volumes containing the NEAR archival data.
  • Multi-Spectral Imager (MSI)
  • Laser Rangefinder (NLR)
  • Infrared Spectrometer (NIS)
  • Magnetometer (MAG)
  • Gamma-Ray Spectrometer (GRS)
  • X-Ray Spectrometer (XRS)
  • Radio Science (RSS)
  • SPICE
• Use the NEAR Expert Search (posted Wednesday, 11-June-2003).
  The NEAR Expert Search allows one to perform specific searches of the NEAR archival data and request selected data to be packaged and downloaded in real time. If you have suggestions for changes or improvements to the NEAR Expert Search, please contact Stef McLaughlin (stefmcl at a s t r o . u m d . e d u) or Ludmilla Kolokolova (ludmilla at a s t r o . u m d . e d u).
• The NEAR shape and gravity models of Eros have been collected in the PDS/SBN Asteroids archival area along with a Gaskell shape model:
  • Gaskell Shape Model of Eros (from MSI data)
  • Collected Shape and Gravity Models of Eros (gathered from NEAR instrument archival volumes)
• Go to the NEAR Eros Coordinate Systems document which describes the different lon/lat systems used by the instrument teams for the NEAR archive and the conversions to IAU Standard Coordinates.

A partial inventory of the NEAR Data Archive is available online at the PDS Data Search.

Mission Information and Archive Search Aids

The following topics will aid your search through the NEAR Data Archive:

• Where can I find...? provides information to help you locate data, shape models, browers, surface features of Eros and Mathilde, et cetera.
• The NEAR documentation set provides one-stop access to all mission documents, instrument documents, observing logs, and data set descriptions.
• Mission phases presents a table of date ranges and durations.
• Data levels defines the different types or levels of process data found in the archive.
• Naming scheme defines the naming convention used for NEAR data volumes.
• Directory structure describes the directory structures within NEAR data volumes.
• Known and discovered problems lists discrepancies found in the final NEAR delivery.
