In 1977, Voyager 1 and 2 started their one-way journey to the end of the solar system and beyond, now traveling a million miles a day. Jimmy Carter was president when NASA launched two probes from Cape Canaveral. Voyager 1 and its twin, Voyager 2, were initially meant to explore Jupiter, Saturn, and their moons. They did that. But then they kept going at a rate of 35,000 miles per hour. Each craft bears an object that is a record, both dubbed the Golden Records. They were the product of Carl Sagan and his team who produced a record that would, if discovered by aliens, represent humanity and "communicate a story of our world to extraterrestrials."
