ESA astronaut Alexander Gerst chose Thomas D’s ‘Rückenwind’ as one of the songs he and his crewmates will listen to in their Soyuz spacecraft while waiting for the final countdown for launch. Thomas D is a founding member of German rap pioneers ‘Die fantastischen Vier’. Thomas D feels very honoured that Alexander picked one of his songs and wishes him all the best. The title of the song, Rückenwind, means tailwind in English.
