The 'Sounds of Earth' record & the American flag are prepared for storage aboard the Voyager 2 spacecraft in 1977. The two Voyager craft, after their journey to the 4 giant gas planets (Jupiter, Saturn, Uranus, Neptune), will eventually leave our solar system & head towards distant stars. In case either craft meets an alien intelligence, the 'Sounds of Earth' is evidence of life on Earth. The record contains electronically imprinted words, photos & diagrams about the Earth. The sounds include greetings in 60 languages, music from different cultures, & the sounds of the wind, surf, animals, & other phenomena.
