SOFIA, the Stratospheric Observatory For Infrared Astronomy, is a joint project by the US space agency NASA and the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) and is expected to operate for 20 years. This is its first ever visit to Europe, and on 18 September 2011 it will be present at German Aerospace Day, and visitors will have the chance to see it. On board will be the German instrument GREAT (German REceiver for Astronomy at Terahertz frequencies), responsible for separating the infrared radiation collected from space by the telescope and into its spectral components.
