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

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.

SpaceX has scheduled two Falcon 9 launches from Cape Canaveral on April 21. The first launch, CRS-32, will carry supplies to the ISS before sunrise, followed by a sonic boom upon the booster landing.

Witness the incredible phenomenon of a mini sonic boom ��​ #physics #theactionlab #science #chemistry #education #sonicboom ...
