Abstract

The Infrared Astronomical Satellite (IRAS) was the first far infrared space telescope to perform observations from orbit. Its excellent overall performance demonstrated life and temperature profiles, that should provide the confidence to proceed with the next major cryogenically cooled telescope, SIRTF. An overview of the cryogenic system design is presented along with the hardware flight performance. Specific flight performance parameters such as optics temperatures, initial stabilization times, and optics and cryogen system temperature profiles after depletion of the superflid helium are highlighted.
