In 1977, The Voyager program sent two spacecraft to explore the solar system and travel to interstellar space. In this video from NASA's Jet Propulsion Laboratory, learn how Voyager 1 and Voyager 2 are now the farthest any spacecraft has traveled from the Sun, and are still making discoveries in the outer reaches of the solar system. As they continue outward beyond the heliosphere, they will traverse interstellar space for a billion years. Each spacecraft carries a golden record with sounds and images from Earth as a message for any future being that may encounter the spacecraft. See the background essay for more about the Voyager program.
