Solar Storms Could Trigger a Rapid Kessler-Style Debris Cascade in Low Earth Orbit
Scientists warn that a powerful solar storm could abruptly trigger a Kessler syndrome–style cascade in Earth's low orbit, turning orbital debris into a self-perpetuating cloud that endangers satellites and could shower debris back to Earth. Researchers introduced the CRASH clock, suggesting a catastrophic collision could unfold in roughly 5.5 days if navigation is disrupted, a sobering risk given the growing megaconstellations from SpaceX, Amazon, and others and the current high rate of in-orbit maneuvers.
