"CRASH Clock. The name stands for Collision Realization And Significant Harm, and the idea is simple enough to be unsettling: estimate how long it would take for a potentially catastrophic orbital collision to occur if satellites could no longer dodge one another, or if operators lost the situational awareness needed to know where objects would be." 5.5 days....
"The authors point to solar storms as one plausible trigger for a broad loss of control or awareness. A strong geomagnetic storm can increase atmospheric drag in low Earth orbit, causing satellites to drift from predicted paths. It can also affect communications, navigation and power systems. Even when spacecraft remain functional, their trajectories may become harder to forecast during and immediately after the disturbance."
And let's not forget the hackers. Some definietly have a score to settle:
This is ridiculous!
"Relentless maneuvers: Starlink satellites executed about 144,000 avoidance burns in six months, an unprecedented rate for any operator."
The more LEOs and the longer they exist, the more human activity becomes critically dependent on them.
