The National Space Science Data Center (NSSDC) at Goddard Space Flight Center in Greenbelt, Maryland is NASA's primary deep archive site for planetary and lunar data obtained from spacecraft missions (both NASA and non-NASA), as well as the primary center for distribution of planetary data and images to educators and the general public. NSSDC is also responsible for the dissemination of photographic products to NASA and non-NASA funded individuals. NSSDC complements the work of two other groups in validating, archiving, and disseminating planetary and lunar data: the Planetary Data System (PDS) and the Regional Planetary Image Facilities (RPIFs).
NSSDC is the permanent archive for NASA lunar and planetary science data. NSSDC holds various relatively recent data on CD-ROM. Many older data sets are available on other offline media (e.g., magnetic tape, photographic products, etc.). Information about ordering data may obtained by contacting our Coordinated Request and User Support Office (CRUSO).
The World Data Center for Satellite Information is co-located with NSSDC and provides descriptions for the spacecraft and experiments. In addition, NSSDC also supplies data to foreign users upon request.
