The Spitzer Space Telescope (SST) (formerly the Space Infrared Telescope Facility (SIRTF)) is an infrared space observatory, the fourth and final of NASA's Great Observatories.
In keeping with NASA tradition, the telescope was renamed after successful demonstration of operation, on December 18, 2003.
Unlike most telescopes which are named after famous deceased astronomers by a board of scientists, the name for SIRTF was obtained from a contest open only to children (to the delight of science educators).
