Car-sized Voyager 1 keeps moving outward past Pluto, outlasting its builders
Launched in 1977, Voyager 1—roughly the size of a small car—still sails outward at about 17 km/s, now well beyond Pluto’s orbit at 166 AU. It communicates at light speed, with signals taking over 23 hours to reach Earth, while its power has dwindled to ~250 watts and only two instruments remain active. The mission has outlived its original four-year plan, outlasting most of its creators, and it carries the Golden Record as a lasting message as it drifts through interstellar space for billions of years.
