Voyager 1: One Light-Day From Home (Full Documentary)

Voyager 1: One Light-Day From Home (Full Documentary) In 1977, NASA launched a machine the size of a small car toward the outer planets. Nearly fifty years later, Voyager 1 is still talking to us, and in November 2026 it becomes the first human-made object to reach one light-day from Earth. This is the full story in one sitting: the launch, Jupiter and Saturn, the Pale Blue Dot and why the cameras went dark for good, the crossing into interstellar space, what a light-day really means, and the Golden Record's billion-year clock. Then we follow it carefully into the far future, and we tell you clearly which parts are measured and which parts are estimates. This film combines our two-part Voyager series with new chapters built around our Voyager Shorts.
