Reported in Chart Attack recently, NASA has uploaded all the sounds they sent to space during the Voyager mission to their Soundcloud page. Launched in 1977, the two Voyager spacecraft were each loaded with a golden phonograph record documenting life on Earth should either probe ever contact aliens.
Their mission was to explore Jupiter, Saturn, Uranus, and Neptune before floating out of our solar system into interstellar space, hurtling away from the sun at 17 kilometres a second. Famous space guy Carl Sagan called the project a “bottle in the cosmic ocean.” Now, for your enjoyment, NASA has uploaded their message to SoundCloud.
The recordings contain greetings in 55 languages, from Akkadian to Wu, as well as an assortment of sounds representative of life on earth, like a heartbeat, a mother kissing her child and the whistle of a train. The golden records also carry 90 minutes of music (not upped to SoundCloud, presumably for copyright reasons), including standards like Chuck Berry’s “Johnny B. Goode” and Beethoven’s Symphony No. 5, First Movement.
