NSSDC is the permanent archive for NASA space science mission data: 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 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.
The WISE Preliminary Release includes data from the first 105 days of WISE survey observations, 14 January 2010 to 29 April 2010, that were processed with initial calibrations and reduction algorithms. Primary release data products include an Atlas of 10,464 calibrated, coadded Image Sets, a Source Catalog containing positional and photometric information for over 257 million objects detected on the WISE images, and an Explanatory Supplement that provides a user's guide to the WISE mission and format, content, characteristics and cautionary notes for the Release products. Ancillary release products include an archive of over 754,000 Single-exposure Image sets and database of over 2.2 billion source extractions from those images, and moving object tracklets identified as part of the NEOWISE program (Mainzer et al. 2011).
