The NASA Space Science Data Coordinated Archive 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, NSSDCA 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. NSSDCA 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, NSSDCA 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.
