Wait, Voyager traveled HOW far?!?!?
In 1977 NASA launched Voyager 1 and 2, two probes boldly going where no spacecraft had gone before! After 35 years of zipping through space these ultimate inanimate explorers still work and are still communicating with us! The Voyager program has been a vital source of information used by astronomers in understanding more about our own cosmic back yard.
