The Trauen site of the German Aerospace Center (DLR) is located in the Lüneburg Heath, in the immediate vicinity of the Bundeswehr airport at Fassberg. Since 1935, the advantageous location distant from settlements and yet close to metropolitan areas has been used to conduct sophisticated experiments for research. Particular scientific attention was paid to the work and experiments of Prof. Eugen Sänger, who played a leading role in setting up the rocket center in Trauen and developed rocket and air-breathing missile propulsion systems. One of his fundamental works is still used today in almost all rocket engines: the cooling of the bell nozzle with the rocket fuel.
Fassberg Airport allows parallel use of the runways if required.
