The Herschel Orion Protostar Survey (HOPS) is an ongoing 200-hour open-time key project with the Herschel Space Observatory to study protostars in the Orion molecular cloud complex. HOPS is obtaining PACS 70 and 160 micron imaging of 286 Orion protostars and PACS spectroscopy of a subset of 36, sampling the expected peaks of their spectral energy distributions (SEDs). The Herschel data are complemented by Spitzer 3-24 micron photometry and 5-40 micron spectroscopy, high angular resolution near-IR imaging with Hubble and ground-based telescopes, and millimeter observations of the surrounding gas. With these combined data we can determine the fundamental properties (multiplicity, gas infall rate, bolometric luminosity, outflow cavity geometry) of a large sample of protostars in a single cloud complex. With far-IR imaging and 1.6-160 micron SEDs for 171 protostars and 55-200 micron spectroscopy for 10 protostars expected to be in hand by mid-March 2011, we will present a selection of recent results.
