National Space Science Data Center (NSSDC)

Voyager-2 Saturns Rings
Voyager 2 false-color image of Saturn's rings from the NSSDC image catalog. Subtle color variations due to differences in surface composition of the particles making up the rings are enhanced in this image produced by combining ultraviolet, clear, and orange frames. The frame was taken from a distance of 8.9 million km on August 17, 9 days before closest approach, and measures about 68,000 km from top to bottom. (Voyager 2, P-23953)

The National Space Science Data Center serves as the permanent archive for NASA space science mission data. "Space science" means astronomy and astrophysics, solar and space plasma physics, and planetary and lunar science. As permanent archive, NSSDC teams with NASA's discipline-specific space science "active archives" which provide access to data to researchers and, in some cases, to the general public.

NSSDC also serves as NASA's permanent archive for space physics mission data. It provides access to several geophysical models and to data from some non-NASA mission data.

In addition to supporting active space physics and astrophysics researchers, NSSDC also supports the general public both via several public-interest web-based services (e.g., the Photo Gallery) and via the offline mailing of CD-ROMs, photoprints, and other items.

NSSDC provides on-line information bases about NASA and non-NASA data as well as spacecraft and experiments that generate NASA space science data. NSSDC also provides information and support relative to data management standards and technologies. More about NSSDC.

Data Available

Master Catalog of Spacecraft Query
This master catalog provides query form for spacecraft (mission) information by name, discipline category, and/or launch date. From that point, it is possible to retrieve information about experiments on the spacecraft and/or data sets available.

NSSDC CD-ROM Catalog
The NSSDC archives 56 different titles with over 1,200 unique volumes at this time.
