The Spitzer Space Telescope is the infrared component of NASA's family of Great Observatories comprised of the Chandra X-ray Observatory, the Compton Gamma Ray Observatory, and the Hubble Space Telescope. Cryogenically cooled and in Earth-trailing orbit, Spitzer currently offers imaging capabilities from 3.6-160 microns, and spectroscopy from 5-38 microns. In approximately March 2009, the liquid helium cryogen on-board Spitzer will be expended, but the observatory will remain operative with 3.6 and 4.5 micron imaging capabilities over two 5'x5' fields-of-view. Sensitivity in these channels will remain unchanged from the cryogenic mission. In this "warm" mission phase, Spitzer can operate until early 2014 with high-efficiency, providing up to 35,000 hours of science observing time. This enables several unprecedented opportunities to address fundamental and key scientific questions requiring large allocations of observing time, while maintaining opportunities for broad community use with more "traditional" time allocations, and funding for archival research. This presentation will review the technical and operational capabilities of Spitzer in the post-cryogen era, and will introduce some of the science enabled by warm Spitzer.
