The Submillimeter Wave Astronomy Satellite (SWAS) was selected for development and flight by NASA in 1989 as one of the initial payloads in the Small Explorer program. SWAS is designed to carry out submillimeter astronomical observations of spectral lines from space. Spectral lines of H2, O2, 13CO, and atomic carbon, which are extremely difficult to observe from the ground but which are potentially important tracers of the structure of dense clouds in the interstellar medium, will be simultaneously observed with high spectral resolution. Incoming radiation will be collected by a 55-cm*71-cm offset Cassegrain antenna, with an aggregate surface error
