Voyager 1 is the most distant human made object ever launched, traveling through interstellar space after completing its original mission to explore the outer Solar System. Its enormous distance means radio signals between Earth and the spacecraft take many hours to travel. NASA describes Voyager 1 as approaching the milestone of one light day from Earth, about 25.9 billion kilometers, in November 2026. The spacecraft continues its historic journey far beyond the planets, carrying a record of humanity into interstellar space.
