dont look up

They are all in LEO, so they would naturally de-orbit in a matter weeks uncontrolled so, who cares?

Kessler Syndrome is cool Sci-fi, but not really possible to stop us from leaving earth. There is a very narrow band where the debris could accumulate (LEO), and as you get further away, the amount of space increases by a cube of the altitude, not to mention that only the "cheapest" low earth orbits would be affected. Things like polar orbits or sun-synchronous orbits aren't affected. The band of debris only hinders stable orbits at that level, i.e. LEO satellites such as starlink constellations would be affected but it doesn't act as an impenetrable barrier. It also doesn't affect useful satellites like GPS.

Basically the problem described only affects the profits of a company that would be the primary cause of the problem. So in a way it's self-correcting.

To showcase the immediacy of the problem these solar storms can cause, the authors came up with a new metric—the Collision Realization and Significant Harm (CRASH) Clock.

which came first, the abbreviation or the long form?

I mean, at this point I'm kinda' hoping for Kessler syndrome... It's so blatantly clear that the rich and powerful do not give two fucks about the consequences of their actions. While they're raping and destroying the Earth, they speak of datacenters in space and colonizing Mars.

At this point, humanity needs to have the French Revolution 2.0 x10, or Kessler Syndrome better make sure we kill ourselves off before our ilk can infect the rest of the solar system.

“Datacenters in space” good luck powering AND cooling that

Wouldn't an event like this potentially cause mass disruption of GPS/GLONASS satellites?

I'm surprised no one has considered this as a potential terrorist threat vector. How difficult would it be to send a balloon/large amateur rocket up to start the domino effect?

GPS Satellites are MUCH further away then LEO. GPS orbits around 20,000km, LEO is 400km. There is no way a non-nation state can get there, let alone the difficulty of actually intercepting those satellites. It's physical possible, of course, but not easy.

It's pretty hard without state-level resources. A balloon can go abou 60km up. LEO begins like 400km IIRC.

[–] 4am@lemmy.zip 3 points 2 hours ago

LEO begins at around 160km. The ISS is between 400 and 420km at any given moment

Don’t know, but it’d be fun to try

[–] thespcicifcocean@lemmy.world 1 points 7 hours ago

Iirc, gps satellites are in geosynchronous orbit, so it's impossible to reach with amateur rockets or balloons. But they could absolutely fuck up the leo satellites

Elonlink can crash and burn.
