Scientists have confirmed that Earth’s seismic sensors are capable of detecting sonic booms generated by space debris reentering the atmosphere, offering a novel method to track objects falling back to the planet. The findings highlight an unexpected intersection between space science and geophysics, where ground-based instruments traditionally used to monitor earthquakes are now revealing signatures of atmospheric shockwaves. Researchers say the data can enhance understanding of reentry events, improve monitoring of orbital debris, and support global safety efforts.
