Story summary

Researchers from Johns Hopkins University and Imperial College London developed a method to track space debris using seismic sensors from existing earthquake monitoring systems, yielding real-time trajectory and speed data.
In a January 2026 study, they analyzed debris reentry from China's Shenzhou-15 spacecraft and found it traveled 25 miles off its predicted path.
Accurate tracking is crucial because falling debris can pose risks to people and the environment.
