We launched Voyager 1 in September of 1977. By January of 1979, it was sending back amazing shots of Jupiter and its moons (including the first evidence of volcanic activity on Io). With November 1980 came Saturn and its moon Titan.
As of now, in late 2008, Voyager is still at work. It’s long since passed the planetary part of our solar system, and is now more than 107 AU from the sun, or about 9.94 billion miles, making it the farthest man-man object by a vast margin. It’s also significantly beyond the orbit of Pluto (30-49 AU; shut up; it is too a planet); signals from Voyager 1 now take in excess of fourteen hours to reach earth.
Sadly, it has not yet produced any contact with Godlike extraterrestrial intelligences nor hot bald alien women.
