In the tradition of the Hubble Deep Fields (HDF-N and HDF-S), the Great Observatories Origins Deep Survey (GOODS) is designed to push the performance of major modern observational facilities to their sensitivity limits. GOODS unites the deepest observations from ground- and space-based facilities at many wavelengths, and was selected in late 2000 as one of six Legacy programs for the Space Infrared Telescope Facility (SIRTF: the fourth of NASA's Great Observatories after Hubble, Chandra and Compton). The Legacy program is meant to “...maximise the scientific utility of SIRTF by yielding an early and longlasting scientific heritage… producing data that will enter the public domain immediately”. Under the leadership of the PI, Mark Dickinson at ST ScI, the programme will map two fields with SIRTF, one Northern one Southern, exceeding a total of 300 square arcmin. GOODS will produce the deepest observations with the SIRTF IRAC instrument at 3.6-8 microns, and at 24 microns with the MIPS instrument pending on-orbit demonstration of instrument performance relative to SIRTF Guaranteed Time observations, which will also survey these same fields at 70 and 160 microns. The depth will be such that ordinary L* galaxies will be detected in their rest-frame near-infrared light out to a redshift of 4 or beyond. Luminous starburst galaxies and AGN - even the obscured ‘type 2' objects - will be seen beyond the current record redshift of ~ 6 if any lie in the fields. At the longest wavelength (24 microns), the mid-IR emission from starburst galaxies will be seen to a redshift ~ 2.5
