VOYAGERS 1 AND 2 (1977):

Voyager 1, having journeyed for more than 30 years, is now the farthest man-made object in the universe at more than 10 billion miles from the sun. Voyager 2 is taking a slower route that allowed flybys of Uranus and Neptune—the first and only space probe to do so. Both spacecraft continue to function today, and they could become the first probes to report back from interstellar space when they escape the solar system as expected in the next five to 10 years. Should they ever encounter an alien civilization, both Voyagers carry a Golden Record, a 12-inch gold-plated LP spearheaded by astronomer Carl Sagan with a selection of music, nature sounds and greetings from Earth in numerous languages.
