Satellite Collision Cascade in Low Earth Orbit Would Likely Shut Down Humanities Access to Space: Risk Analysis
Humanity is very quickly loading up Low-Earth-Orbit (LEO) with satellites. The space is getting so crowded, that with an unexpected loss of satellite maneuverability to avoid collisions, we would start to experience collisions within about 3.8 days.
One collision would generate hundred or even thousands of debris chunks. Any one of these chunks hitting another satellite would generate hundreds to thousands more chunks. And so on... A rapidly cascading sequence of more and more collisions (so-called Kessler Syndrome) would quickly fill LEO with so much debris that it could become impossible to launch any satellite or mission into space, effectively isolating Earth from space.
Forget about AI servers in space, or missions to the Moon or Mars if this Kessler cascade were to occur. Forget about Starlink and other other space-based constellation of satellites for internet. Forget about replacing any defunct geostationary communications satellites. We would be in a different world...

An Orbital House of Cards: Frequent Mega-constellation Close Conjunctions
Link: arxiv.org/pdf/2512.09643
Abstract
The number of objects in orbit is rapidly increasing, primarily driven by the launch of mega-constellations, an approach to satellite constellation design that involves large numbers of satellites paired with their rapid launch and disposal. While satellites provide many benefits to society, their use comes with challenges, including the growth of space debris, collisions, ground casualty risks, optical and radio-spectrum pollution, and the alteration of Earth’s upper atmosphere through rocket emissions and reentry ablation. There is potential for current or planned actions in orbit to cause serious degradation of the orbital environment or lead to catastrophic outcomes, highlighting the urgent need to find better ways to quantify stress on the orbital environment. Here we propose a new metric, the CRASH Clock, that measures such stress in terms of the timescale for a possible catastrophic collision to occur if there are no satellite manoeuvres or there is a severe loss in situational awareness. Our calculations show the CRASH Clock is currently 5.5 days, which suggests there is limited time to recover from a wide-spread disruptive event, such as a solar storm. This is in stark contrast to the pre-mega-constellation era: in 2018, the CRASH Clock was 164 days.
