Submillimeter Wave Astronomy Satellite
NASA’s Submillimeter Wave Astronomy Satellite (SWAS) was a space observatory built to look for water and other molecules associated with life as we know it. During its seven years of operation, SWAS provided the first measure of the distribution of water in the Milky Way. Astronomers also used the observatory to make important discoveries about the interstellar clouds where new stars and planets are born, as well as observations of planets and comets within the Solar System. Center for Astrophysics | Harvard & Smithsonian scientists and engineers designed the telescope for SWAS, and the CfA hosted the operations center for the spacecraft. SWAS operated from 1998 through 2005, when it was put into hibernation mode.
