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. As of June 2014, 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.
