Voyager 1 Is About to Be One Light-Day From Earth

On November 18, 2026, a message sent to Voyager 1 will take a full day to arrive. No human-made object has ever been this far from home. How a spacecraft launched in 1977 got there: the rare planetary lineup, Io's volcanoes, the choice at Titan, the Golden Record, the Pale Blue Dot, the crossing into interstellar space… and how its team fixed a computer from 15 billion miles away. Every fact is sourced from NASA and JPL. A song or a photo: what would you add to the Golden Record? 👇 Chapters 0:00 Introduction 0:37 Launched Second, Arriving First 1:57 Two Giants and a Fork in the Road 3:10 A Record and a Pixel 5:04 Crossing the Boundary 6:47 Fixing a Computer 15 Billion Miles Away 8:44 One Light-Day Sources: NASA Science, Voyager mission pages (Voyager 1, Planetary Voyage, Golden Record, Pale Blue Dot, What is a light-day?, FAQ, Fast Facts); NASA JPL news releases (2013, 2017, 2020, 2022, 2024, 2025); NASA Voyager blog (2023-2026); NASA History Office (SP-4219; J.
