Scientists track European rocket debris using sound waves from space crash

Researchers analyzed acoustic signals from a Falcon 9 rocket stage that burned up over central Europe in February 2025, developing new methods to monitor uncontrolled spacecraft re-entries. The technique offers policymakers and space operators a tool to better understand and track the growing risk of orbital debris falling to populated regions.
