Sonic Booms Reveal Space Junk's True Path
23 Jan
Summary
- Earthquake monitors can track space junk using sonic booms.
- Seismic data pinpointed a Chinese module's path 20 miles off.
- This method aids recovery teams for dangerous falling debris.
Scientists have discovered a novel method to track space debris using earthquake monitors that detect sonic booms. This technique proved effective when analyzing the reentry of a discarded Chinese module over Southern California in 2024.
Seismic data from over 120 seismometers accurately mapped the module's trajectory, placing its predicted path nearly 20 miles farther south than orbital radar had estimated. This advancement is crucial for tracking uncontrolled objects plummeting at supersonic speeds.
Lead researcher Benjamin Fernando highlighted the challenge of tracking debris once it begins breaking up in the atmosphere. The study, published in Science, suggests seismic tracking could significantly improve the speed and accuracy of identifying debris fall-out zones.
With the growing number of satellites in orbit, the risk of dangerous space debris increases. This seismic tracking method offers a promising solution for enhanced safety and quicker recovery operations for falling space objects.
