Résumé

The Space Infrared Telescope Facility (SIRTF) is the last of NASA's four great observatories, scheduled for launch in 2001. At the heart of the SIRTF observatory is a 363-litre, superfluid helium cryostat, designed and built by Ball Aerospace & Technologies, Inc. The cryostat provides the direct cooling of the three scientific instruments which will observe the infrared universe. One major innovation of the SIRTF observatory is that the instrument optics are launched warm, and cooled down on orbit to the final operating temperature of 5 K by radiation to space and direct vapor cooling by the effluent helium.
