Earthquake Sensors Detect Sonic Booms From Incoming Space Junk
Seismic sensors can detect sonic booms from reentering space junk, offering a new tracking method. Researchers successfully used ground-based seismic instruments to precisely measure the speed, altitude, and fragmentation of the Shenzhou-15 orbital module during its 2024 reentry. This breakthrough enhances space situational awareness and debris hazard mitigation by improving predictions of where falling debris may land.
