Seismic Signals Map Space Debris Path in Real Time
Researchers show that existing earthquake seismometers can detect shock waves from reentering space debris, enabling near real-time tracking of its path and potential landing sites; using 127 seismometers across southern California to map China's Shenzhou-15 module's descent (Mach 25–30) they estimated speed, altitude, and breakup points—information that can complement radar predictions and speed debris recovery to reduce hazards.
