In 1977, NASA launched the Voyager missions as a way of exploring the solar system's outermost planets, capturing images of Jupiter, Saturn, Uranus, Neptune, and their moons. "The farthest" documents Voyager's journey, including first-hand accounts of the men and women who built the ships and guided their missions. Bonus film "Second genesis" explores the scientific quest to find life, or evidence of it, beyond Earth.
