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 […]
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.
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.
