Dr. Carl Sagan and his collaborators were faced with the Herculean task of describing humanity and our planet to beings without even having basic ideas about us. Their solution was quite ingenious and will hopefully one day pay off. Where are they now?

With this mission seemingly complete, NASA seemed content to let Voyager's ships blast off through the stars. And so they did. Voyager 1 and 2 are among the fastest machines ever created by man.
