Summary
November 18, 2026 is the date NASA says Voyager 1 will become the first human-made object to reach one light-day from Earth—about 25.9 billion kilometers, or 173 times the Earth-sun distance.
A radio command sent that day would take 24 hours to reach the spacecraft, and a reply would take another 24 hours, underscoring how far the probe has traveled since its 1977 launch.
Voyager 1 has covered that distance at roughly 128,700 kph and is expected to keep flying after its science instruments lose power in the early 2030s.
The milestone also carries the Voyager Golden Record, including 27 music selections such as Georgia's polyphonic folk song Chakrulo, further into interstellar space.
