Overview

• The Vienna Symphony Orchestra will perform Johann Strauss II's 'Blue Danube' waltz, which will be transmitted into space using ESA's deep-space antenna in Spain.
• A pre-recorded version of the waltz from a rehearsal will be sent to avoid technical issues, while the live performance will accompany the event on Earth.
• The signal will travel at the speed of light, reaching NASA's Voyager 1 spacecraft, over 15 billion miles from Earth, within 23 hours.
• This initiative aims to rectify the exclusion of Strauss' iconic piece from the 1977 Voyager Golden Records, which included other classical and modern music.
• The event celebrates multiple milestones, including the 50th anniversary of ESA, the 200th birthday of Strauss, and the 125th anniversary of the Vienna Symphony Orchestra.
