On September 5, 1977, NASA’s Voyager 1 spacecraft lifted off from Cape Canaveral, Florida, aboard a Titan-Centaur rocket. Thirty-five years later, the planetary probe is now an interstellar traveler, having traveled farther from Earth than any manmade object in history. As of 21:00 Universal Time on September 4, 2012, Voyager 1 was 18.21 billion kilometers (11.31 billion miles) from home, or 121 times the distance from the Earth to the Sun. Light takes 33 hours and 44 minutes to travel the distance from Voyager 1 to Earth. (via A Voyager Far From Home : Image of the Day)
