Would the farthest probe we’ve ever sent… ever be caught by the fastest probe we’ve ever built? Voyager 1 is still moving at 38,000 mph, more than 15.7 billion miles from Earth — while NASA’s Parker Solar Probe races around the Sun at 430,000 mph, the fastest human-made object in history. If Parker could somehow hold that speed… it would reach Voyager’s distance in just about four years. Not yet — but it’s still chasing history. #nasa #space #universe #science | ScienceExplained
