An overview is presented of the Space Infrared Telescope Facility (SIRTF), a one-meter-class cryogenically-cooled observatory for IR astronomy from space that will be the IR component of NASA's family of Great Observatories. SIRTF will operate at an altitude of 100,000 km and achieve its five year lifetime without the complication of on-orbit cryogenic replenishment and have twice the on-target efficiency that could be realized in LEO. The observations will permit the development of a direct empirical picture of the time evolution of cosmic phenomena, such as evolution of the chemical and stellar content of galaxies and the growth and decay of the quasar population.
