MIPS photometry will be obtained for a large sample of young, relatively nearby (generally within 100 pc) stars. The primary objectives of this program are: 1) identify systems possessing warm dust emission analogous to the zodiacal bands of the inner solar system, 2) find further examples of the pre-main-sequence planetary debris system (PDS) discovered for HD 98800B, and 3)identify Vega-type cooler dust excesses early in the evolution of their illuminating stars. This survey will constrain models of the origin and evolution of PDSs with the ultimate goal of determining how often, and in what circumstances terrestrial planets are formed. In addition, the survey will identify objects having mid-IR excesses that will be suitable targets for follow-up ground- and space-based observations at higher resolution. This program is a collaboration among four SIRTF GTOs (F. Low, M. Werner, M. Jura, and R. Gehrz). Each GTO will will submit his portion of the observational program separately.
