We sometimes forget that the marvelous Voyager spacecraft are still flying through the distant Cosmos! NASA placed an ambitious message aboard Voyager 1 and 2-a kind of time capsule, intended to communicate a story of our world to extraterrestrials. Each Voyager spacecraft carries a 12-inch gold-plated copper disk phonograph recording containing sounds and images of Earth specially selected to portray the diversity of life and culture on our planet.This cover is one of a set of 7 covers upon which are the original and authentic signatures of 40 members of the Voyager project team.Buyer will receive the complete set of 7 covers. A little known fact is that aside from carrying the gold disks the Voyagers also carry these same signatures and others tucked inside the gold foil of their bus terminals. At present both spacecraft are heading in the direction of the Sirius Star system. This is certainly a rare item, and is possibly one of a kind.
