US Edition2.8 Days to Disaster: Why We Are Running Out of Time in Low Earth Orbit
Mega-constellations cause satellites to face a collision every 22 seconds in low-Earth orbit, with a 30% chance of catastrophe if control is lost for 24 hours, researchers say.

2.8 Days to Disaster - Why We Are Running Out of Time in Low Earth Orbit
A “House of Cards” is a wonderful English phrase that it seems is now primarily associated with a Netflix political drama. However, its original meaning is of a system that is fundamentally unstable. It’s also the term Sarah Thiele, originally a PhD student at the University of British Columbia, and now at Princeton, and her co-authors used to describe our current satellite mega-constellation system in a new paper available in pre-print on arXiv.
In the low-Earth orbit, a fundamentally unstable system of satellite mega-stars has emerged. New estimates suggest that in the event of a loss of spacecraft control, a catastrophic collision could occur in less than three days, Phys. Among them, Sarah Teele of Princeton University describes a modern orbital infrastructure as a "card house." According to their data released in arXiv, in a low-Earth orbit, satellites approach less than one kilomet…
Earth Orbit Is Now One Software Failure Away From Disaster
Earth orbit is no longer a vast, forgiving expanse where mistakes unfold slowly. According to a new scientific analysis, it has become a tightly coupled, failure sensitive system where a single breakdown in automation, communication, or situational awareness could trigger a catastrophic satellite collision in a matter of days. Not decades. Not years. Days. The […] The post Earth Orbit Is Now One Software Failure Away From Disaster appeared first…
