As permanent archive, NSSDC teams with NASA's discipline-specific space science "active archives" which provide access to data to researchers and to the general public. NSSDC also serves as NASA's primary active archive for space physics mission data and for selected NASA astrophysics missions. 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 online information about NASA and non-NASA spacecraft and experiments, and about data management standards and technologies. http://nssdc.gsfc.nasa.gov/nmc/sc-query.html Archive University Research General Informal Education Radio Millimeter Infrared Optical UV X-ray Gamma-ray
