Next Wednesday, November 18, NASA's Voyager 1 will become the first spacecraft ever to travel one light-day away from Earth: That's a mind-blowing 26 billion kilometers!
Launched way back in 1977 for what was supposed to be just a four-year mission, Voyager 1 is still going strong after nearly five decades.
NASA is even throwing a "shine Bright for Voyager's Light-Day" celebration to mark the occasion.
Voyager 1 exploring interstellar space
Voyager 1 zipped past Saturn in 1980 and hit speeds of 60798km/h.
It became the most distant human-made object in 1998 and, after later crossing the heliosphere, has been exploring interstellar space, still sending data home at a slow but steady pace.
Scientists expect it'll keep working into the 2030s, helping us learn more about what lies beyond our solar system: proof that curiosity can take you pretty far!
