First results from SOFIA early science observations

We will describe the rationale, status, and potential of the Stratospheric Observatory for Infrared Astronomy (SOFIA), which has sucessfully started semi-regular observing flights in 2011. SOFIA is a Boeing 747-SP aircraft, modified to carry a 2.5m telescope capable of diffraction-limited observations at lambda>20microns. It flies at altitudes up to 45000 feet, above more than 99% of the precipitable water vapor. With a projected lifetime of 20 years it will outlive the Herschel satellite and will be the premier far-infrared platform for the next decade or two. First SOFIA science results include mid-IR (5-40mu) imaging of the Orion BNKL region and the galactic circumnuclear disk (with FORCAST, a camera from Cornell University; PI T. Herter) as well as Tera-Hertz spectroscopic maps of warm CO and the ionized carbon line at 158 microns in the M17SW star forming region (with GREAT, a high spectral resolution heterodyne spectrometer from MPIfR Bonn; PI R. Guesten).
