SUMMARY:Infrared Astronomy at 45\,000 Feet\, Astronomy Colloquium\, Pa
 m Marcum\, NASA
DESCRIPTION:The joint U.S. and German Stratospheric Observatory for In
 frared Astronomy (SOFIA) will be a premier observatory facility during
  future decades for studying the physics and chemistry of stellar evol
 ution processes. Utilizing the large suite of science instruments and 
 the broad wavelength coverage of SOFIA\, astronomers will be armed wit
 h unique capabilities to undertake a large breadth of investigations r
 anging from studies of the Solar System to the star forming history of
  galaxies over cosmic time.  SOFIA is a German-built 2.5-meter telesco
 pe mounted in a modified Boeing 747-SP aircraft supplied by NASA. Flyi
 ng at altitudes as high as 45\,000-feet\, SOFIA will be above most of 
 atmospheric water vapor that severely limits the ability to do infrare
 d and sub-mm observations using ground-based telescopes. SOFIA's first
 -generation instruments include broadband imagers\, moderate resolutio
 n spectrographs capable of resolving broad features due to dust and la
 rge molecules\, and high resolution spectrometers suitable for kinemat
 ic studies of molecular and atomic gas lines at suitable resolution. S
 OFIA science applications will be discussed\, with special emphasis on
  investigations related to infrared spectroscopy of astrophysical gas\
 , grains and ices. Although the primary impact of SOFIA will be its sc
 ientific return\, SOFIA's other major advantages include the provision
  of a platform on which  to demonstrate new future technologies and to
  provide in-flight experience to young scientists\, educators and jour
 nalists. <br>
