 || '''17.03.2025''' || '''Jörg F. Wagner (University of Stuttgart)''' || '''The SOFIA flying observatory: technology and history'''[[BR]][[BR]]SOFIA was an airborne observatory of NASA and DLR for infrared astronomy. It was operated at altitudes of around 13 km, where observation conditions are better than on the ground. A large reflector telescope was installed in the fuselage of a Boeing 747. Compared to satellite-borne observatories, SOFIA's observation instruments could be easily replaced and were directly accessible to scientists in flight. Construction and commissioning of the observatory lasted from 1999 to 2014, with observation operations continuing until 2022. The lecture presents the technology and history of the SOFIA project.[[BR]][[BR]]Presentation: German[[BR]]Slides: German[[BR]]Questions: German, English ||

These require a new generation of receivers and telescopes, which I will discuss. Both projects are in the planning phase, and the prototypes of both telescopes are currently being built by the German company mtex. The reflectors and turnheads are being manufactured by the company CONCAD in Walldürn, which we will visit as part of this year's company outing.[[BR]][[BR]]Presentation: German[[BR]]Slides: German[[BR]]Questions: German, English ||
