Voyager 1

Voyager 1

Voyager 1, the unmanned space craft launched by the U.S. National Space and Aeronautics Administration when Jimmy Carter was president, is on the verge of leaving the solar system, over 10 billion miles from earth, the British Broadcasting Corp. said, citing mission officials.
Since 2004, the unmanned probe has been exploring a region of space where the solar wind slows abruptly and crashes into the thin gas between stars.
Voyager 1 is traveling faster, at a speed of about 38,000 mph, compared to Voyager 2′s velocity of 35,000 mph
