35 years later, Voyager 1 is heading for the stars

This artists rendering provided by NASA shows the Voyager spacecraft. Launched in 1977, the twin spacecraft are exploring the edge of the solar system. Thirty-five years after leaving Earth, Voyager 1 is reaching for the stars. Sooner or later, the workhorse spacecraft will bid adieu to the solar system and enter a new realm of space _ the first time a man-made object will have escaped to the other side. (AP Photo/NASA)
