Crash Clock: How Quickly Satellites Could Collide After a Severe Solar Storm
What the Crash Clock Reveals Researchers studying the aftermath of extreme solar activity have introduced the concept of the “Crash Clock”—a model that estimates how fast satellite collisions could cascade once a severe solar storm disrupts maneuvering and deconfliction in Earth’s orbit. The study warns that with tens of thousands of objects racing through low…
