In 1977, NASA launched twin Voyager spacecraft. An emotional, cinematic documentary, The Farthest tells their story through first-hand accounts from the passionate men and women who built the ships and guided their journeys. Negotiating a series of perils on it's Grand Tour of the outer planets, Voyager beamed back spectacular images of Jupiter, Saturn, Uranus, and Neptune. But their moons offered bigger surprises - volcanoes, geysers, and a liquid water ocean. On the chance of discovery by intelligent aliens, each spacecraft carried a Golden Record with music and spoken greetings.
