 Space Today Online - SIRTF - the Space Infrared Telescope Facility
Spitzer (SIRTF) is a 3,000-lb., 0.85-meter, cryogenically-cooled, space telescope operating as an unmanned infrared astronomy observatory in a solar orbit far beyond the Earth and the Moon.
Spitzer has a solar shield and is in an unusual Earth-trailing solar orbit, which places the satellite far enough away from the Earth to allow the telescope to cool without using large amounts of cryogen coolant.
The image by Spitzer's infrared array camera is a four-color composite of invisible light, showing in blue the emissions from wavelengths of 3.6 microns, in green the 4.5 micron emissions, in yellow the 5.8 micron emissions, and in red the 8.0 micron emissions.

Spitzer also made major advances in stellar dynamics, contributing to the understanding of "relaxation" and how this process caused a dense stellar system to inexorably approach a singular state, the approach accelerated by the existence of a spectrum of stellar masses but retarded by the presence of binaries.
Among Spitzer's international honors are the 1975 Karl Schwarzschild Medal, the 1978 Gold Medal of the Royal Astronomical Society and the 1980 Jules Janssen Medal of the Societe Astronomique de France.
