As more and more space junk comes crashing down, a new study shows how earthquake monitors can better track incoming objects by tuning into their sonic booms.
Scientists reported Thursday that seismic readings from sonic booms that were generated when a discarded module from a Chinese crew capsule reentered over Southern California in 2024 allowed them to place the object's path nearly 20 miles (30 kilometers) farther south than radar had predicted from orbit.
