NASA, PBS marking 40 years since Voyager spacecraft launches
CAPE CANAVERAL, Fla. (AP) — Forty years after blasting off, Earth’s most distant ambassadors — the twin Voyager spacecraft — are carrying sounds and music of our planet ever deeper into the cosmos.
Think of them as messages in bottles meant for anyone — or anything — out there.
This Sunday marks the 40th anniversary of NASA’s launch of Voyager 2, now almost 11 billion miles distant. It departed from Cape Canaveral on Aug. 20, 1977 to explore Jupiter and Saturn.
Voyager 1 followed a few weeks later and is ahead of Voyager 2. It’s humanity’s farthest spacecraft at 13 billion miles away and is the world’s only craft to reach interstellar space, the vast mostly emptiness between star systems. Voyager 2 is expected to cross that boundary during the next few years.
Each carries a 12-inch, gold-plated copper phonograph record (there were no CDs or MP3s back then) containing messages from Earth: Beethoven’s Fifth, chirping crickets, a baby’s cry, a kiss, wind and rain, a thunderous moon rocket launch, African pygmy songs, Solomon Island panpipes, a Peruvian wedding song and greetings in dozens of languages. There are also more than 100 electronic images on each record showing 20thcentury life, traffic jams and all.
NASA is marking the anniversary of its back-to-back Voyager launches with tweets, reminisces and still captivating photos of Jupiter, Saturn, Uranus and Neptune.
