The National Space Science Data Center (NSSDC) at Goddard Space Flight Center in Greenbelt, Maryland is NASA's primary deep archive site for space physics and solar data obtained from spacecraft missions (both NASA and non-NASA). NSSDC complements the work of other groups in validating, archiving, and disseminating space physics and solar data: the Space Physics Data Facility (SPDF) and the Solar Data Analysis Center (SDAC), both also located at Goddard.
NSSDC is the permanent archive for NASA space physics and solar data. NSSDC holds various relatively recent data on CD-ROM and other media. Many older data sets are also available. 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.
