The spitzer space telescope mission

open access: yesAdvances in Space Research, 2005
Abstract The Spitzer Space Telescope, NASA’s Great Observatory for infrared astronomy, was launched 2003 August 25 and is returning excellent scientific data from its Earth-trailing solar orbit. Spitzer combines the intrinsic sensitivity achievable with a cryogenic telescope in space with the great imaging and spectroscopic power of modern detector ...

The Spitzer Space Telescope [PDF]

open access: possibleOptical Engineering, 2012
The Spitzer Space Telescope, which has operated very successfully since 2003 in its unique Earth-trailing solar orbit, is NASA's Great Observatory for infrared astronomy. We provide a quick overview of the optical characteristics of Spitzer and review the observatory design.

Optimizing cryogen utilization on Spitzer Space Telescope [PDF]

open access: possibleSPIE Proceedings, 2004
The instruments of the Spitzer Space Telescope are cooled directly by liquid helium, while the optical system is cooled by helium vapor. The greater the power dissipation into the liquid helium, the more vapor is produced, and the colder the telescope. Observations at shorter wavelengths do not require telescope temperatures as low as those required
