It was, perhaps, the ultimate mixtape: a 90-minute selection of music, recorded on a gold-plated copper disk that was sent into space aboard the spacecraft Voyager 2, on August 20, 1977. Knowing that the path of Voyager would take it, and its twin, past the outer planets and out of the Solar System, NASA decided to create an ambitious message for them to carry along.A committee headed by astronomer Carl Sagan selected the contents of the record, which also included photographs, natural sounds, and spoken word greetings to extraterrestrial civilizations in dozens of languages. The music is an eclectic selection from different cultures, nations, and eras. You may recognize "Johnny B. Goode" by Chuck Berry, "Dark Was The Night, Cold Was The Ground" by Blind Willie Johnson, J.S. Bach's Brandenburg Concerto No. 2, but there are also works from Peru, Indonesia, Senegal, New Guinea, Azerbaijan, and the Solomons.
Mixtapes (or mix CDs) can say a lot about the person (or species) who compiles them. Although the two Voyagers won't pass near another star for 40,000 years, it was the hope of Sagan and his team that someone or something, finding them, would discover who we are, and like finding a message in a bottle, would maybe look us up someday. Hopefully, we'll still be around.
Here's Chuck Berry with "Johnny B. Goode"
