Space junk on 5,800-mph collision course with moon
The moon is about to get walloped by 3 tons of space junk, a punch that will carve out a crater that could fit several semitractor-trailers. The leftover rocket will smash into the far side of the moon at 5,800 mph (9,300 kph) on Friday, away from telescopes’ prying eyes. It's been tumbling haphazardly through space, experts believe, since China launched it nearly a decade ago.
