Old satellites and other space junk fall toward Earth every day, and the shock waves they create could be used to track their ...

Falling satellites and large orbital debris create massive sonic booms and scientists are using them to track dangerous space junk.

The sensors used to listen for earthquakes could help protect people from the hazards created by falling spacecraft.

Scientists have discovered a novel method to track space debris, utilizing atmospheric sonic booms as the debris reenters Earth's atmosphere.
