Voyager 1 is closing in on a staggering distance that no human-made object has ever touched before, standing just days away from reaching a full light-day away from Earth. Launched nearly fifty years ago in 1977, the spacecraft has been steadily hurtling through the cosmos at a speed of nearly 38,000 miles per hour, eventually slipping out of our sun's protective bubble and into interstellar space. At 5:16 in the morning Eastern time on November 18, 2026, the probe will officially cross the 16.09 billion mile mark, which is the exact distance that a particle of light travels in twenty-four hours.
To celebrate this monumental milestone, NASA is inviting people around the world to participate in the Shine Bright for Voyager campaign after sunset on November 17. The public can use a dedicated online tool on their phones or tablets, or use a simple flashlight, to flash the letters V-G-R in Morse code toward the night sky as a symbolic wave of light to greet humanity's farthest traveler. While the spacecraft's dwindling plutonium power source means its radio voice will eventually go silent in the coming decade, this upcoming record highlights nearly half a century of unprecedented engineering endurance.
How do you think future generations will view these early robotic probes once humanity begins venturing deeper into interstellar space on our own?
