Ground-based and compact Chinese technology can disrupt or damage Starlink satellites operating in low Earth orbit.

    A cascade of satellite collisions is called Kessler syndrome and the risk of it happening is rapidly increasing due to megaconstellations like Starlink:

    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-megaconstellation era: in 2018, the CRASH Clock was 164 days.

    Kessler syndrome could be a solution to the Fermi paradox.
