35 years later, Voyager 1 is heading for the stars

Voyager 1 is currently more than 11 billion miles from the sun. Twin Voyager 2, which celebrated its launch anniversary two weeks ago, trails behind at 9 billion miles from the sun.

They're still ticking despite being relics of the early Space Age.

Each only has 68 kilobytes of computer memory. To put that in perspective, the smallest iPod - an 8-gigabyte iPod Nano - is 100,000 times more powerful. Each also has an eight-track tape recorder. Today's spacecraft use digital memory.

The Voyagers' original goal was to tour Jupiter and Saturn, and they sent back postcards of Jupiter's big red spot and Saturn's glittery rings. They also beamed home a torrent of discoveries: erupting volcanoes on the Jupiter moon Io; hints of an ocean below the icy surface of Europa, another Jupiter moon; signs of methane rain on the Saturn moon Titan.
