>>> it is believed, though not confirmed, that mankind has sent an object outside our own solar system for the first time. voyager i was launched 35 years ago to explore the planet. it traveled 11 billion miles. now some astronomers say it and its companion, voyager ii are the two most distant active representatives of humanity and its desire to explore. if all the cars made were as well made as the voyager there would be no need for a break-down lane.
