Starlink satellites are making thousands of avoidance maneuvers as low Earth orbit becomes more crowded, feeding worries that a catastrophic impact is inevitable. SpaceX’s orbital communication satellites performed maneuvers just over 25,000 times in the six-month period between December 1, 2022, and May 21, 2023, the company told the Federal Communications Commission in a recent […]
Running fiber globaly is very expensive. The satellite solution has its cons, but it’s available to a lot of people who otherwise might not have access.
It is expensive, but in SOME rural areas it’s still affordable. Obviously not in poorer ones, but it might get cheaper over time. Or it might not. Who knows.
I recall that the decaying orbit means that they constantly have to put more satellites up. All that energy, all that propellant, and all that space garbage. Billions of dollars wasted. Better spent on fiber. Once installed, baring cuts, it will last for nearly 100 years or more. It has benefits for some, but, IMHO, resources are better spent on fiber.
These are in LEO. Once they lose propulsion after 3-5 years, they fall and burn up on re-entry. It isn’t possible for these satellites to cause Kessler Syndrome.
It could send debris into a more elliptical orbit, but it wouldn’t be possible for it to raise the entire orbit above LEO. The point of impact will remain in the orbital path and since the entire orbit is currently in LEO, there will be, by extension, some part of the new orbit still in LEO and therefore subject any debris to atmospheric capture.

Universal global fiber is sadly unlikely to happen. I wish it wasn’t so, but the fight for me to get fiber in a town has been a decade.
Kessler syndrome is one hell of a lot more expensive than fiber.

Could a high-speed impact not send debris flying into a higher orbit?
It could send debris into a more elliptical orbit, but it wouldn’t be possible for it to raise the entire orbit above LEO. The point of impact will remain in the orbital path and since the entire orbit is currently in LEO, there will be, by extension, some part of the new orbit still in LEO and therefore subject any debris to atmospheric capture.
