The Voyager mission is unique. Two identical spacecraft, lauched in 1977, were sent on a journey allowing them to explore Saturn and Jupiter and then onto Neptune, Uranus and beyond. The Voyagers continue to speed away from the Earth and, although the planets have been left far behind, the spacecraft return measurements on a daily basis as they continue to provide ground-breaking discoveries.
