Overview

• On May 31, the Vienna Symphony performed Johann Strauss II’s 'An der schönen blauen Donau' at Vienna’s Museum of Applied Arts
• The digital performance was sent via ESA’s deep-space antenna in Cebreros, Spain to Voyager 1
• The transmission will reach the probe on June 1 after traversing roughly 25 billion kilometers over 23 hours
• The effort remedies the waltz’s omission from Voyager 1’s original 1977 Golden Record
• The initiative commemorates Strauss’s bicentenary and the ESA’s 50th anniversary, with the faint signal’s detectability reliant on other civilizations’ technical capabilities
