Infrared Science Archive

The Infrared Science Archive (IRSA) curates the science products of NASA's infrared and submillimeter projects, such as the Spitzer Space Telescope, the Wide-field Infrared Survey Explorer (WISE), the Infrared Astronomical Satellite (IRAS), and the Two Micron All-Sky Survey (2MASS). IRSA also serves data from infrared and submillimeter European Space Agency missions with NASA participation, including the Infrared Space Observatory (ISO), Planck, and the Herschel Space Observatory. , IRSA provides access to more than 20 billion astronomical measurements, including all-sky coverage in 20 bands, spanning wavelengths from 1 micron to 10 millimeters. Approximately 10% of all refereed astronomical journal articles cite data sets curated by IRSA.

IRSA is part of the Infrared Processing and Analysis Center (IPAC) and is located on the campus of the California Institute of Technology. It is one of NASA's Astrophysics Data Centers, along with the High Energy Astrophysics Science Archive Research Center (HEASARC) and the Barbara A. Mikulski Archive for Space Telescopes (MAST).
