The Voyager Recordings

0708VoyagerCover.gif When Voyager I and Voyager II were launched in 1977, their purpose wasn’t limited to teaching humans about the universe. Aboard each is a gold-plated copper disk designed by astronomer Carl Sagan and other scientists. The disc is actually an audio record containing natural sounds, 90 minutes of music, and 55 spoken greetings. It also includes 115 images encoded in analog. The records were stored in aluminum cases along with a cartridge and needle. On each case is an extremely detailed diagram of how to play the record, starting with the rotation of a hydrogen atom.

While this NASA page has a good selection of pieces from the record, the Latvian electronic arts and media center E-Lab is hosting more.

Voyager I became the most distant human-made object from the Sun on February 17, 1998 and it's still traveling. It was 9,597,000,000 miles away on July 6, 2007. NASA still provides weekly reports on both crafts.
