Take a grand tour through the outer planets and beyond the solar system with the NASA Voyager space probes. Launched in 1977, Voyager 1 and Voyager 2 were the first spacecraft to explore all the outer planets and the first human-made objects to reach interstellar space. They each hold a golden record with the sights, sounds, music, and languages of Earth. These great Voyagers continue to reach for the stars as Earth's intergalactic ambassadors.
