Cool Stars 14 - Submitted Abstract # 312 This version created on 05 October 2006 The Spitzer Space Telescope Extended Mission G. Helou, Spitzer Science Center, Caltech B.T. Soifer, Spitzer Science Center, Caltech After Spitzer runs out of liquid Helium, it will still be possible to operate two of the IRAC channels at essentially undegraded performance. The research community will still be extracting novel science from the archive, and last but not least, the Spitzer Science Center will be carrying out final processing for the data from the cryogenic mission. The Spitzer Science Center is working with the Spitzer project and NASA to define the guiding principles of a Warm Spitzer Mission that exploits these science opportunities in a cost-effective fashion. A key element of the planning for the Warm Spitzer Mission is participation by the user community in assessing the scientific potential of a warm Spitzer Observatory, and in considering the various means to realize that potential. ----------------------------------
