We propose confusion-limited MIPS 70um imaging of the GOODS Hubble Deep Field North (HDF-N). The goal of these observations is to determine the infrared properties of the highest redshift sources detectable by the MIPS on Spitzer. In particular, we will derive source counts at the faintest possible depths and measure the infrared luminosity function out to z~1.5. We will also measure the 70um/24um flux density ratios to constrain what fraction of the infrared background arises from infrared-cool, starburst dominated luminous infrared galaxies versus infrared-warm AGN. Ultraluminous infrared galaxies contribute significantly to the total star-formation at high-redshift and are expected to be detected at flux levels near the confusion limit of the MIPS-70 band. Due to the much lower than expected in-flight performance of the 70um detectors and the loss of over half the array due to cabling issues, the planned observations of the HDF-N by the MIPS-GTO team will not reach the confusion level or the depth required to detect high-redshift sources at 70um. We propose to observe the HDF-N field to the ultimate depth at 70um. These observations are motivated by the GOODS philosophy of obtaining the deepest possible images from NASA's Great Observatories (HST, Chandra, and Spitzer) and will greatly build upon our knowledge of the high-redshift universe by probing the far-infrared band to unprecedented depths.
