Starlink is a very low orbit. Even if something like that happened, it would clean itself up in like five years
Sorry, you're probably right. It's a thing I expect to be problematic if the future. Of course all problems will burn up in the atmosphere...
Not wrong, and yet small parts of that 'orbit' would kinetically increase, in a Kessler sort of way...
When 2 satellites collide, the pieces don't all stay on the same altitude. Even though none of them will be in a stable orbit, all it takes is for one piece to smack into a satellite that's a bit higher up before it de-orbits, and boom, now you've got a debris field that won't de-orbit.
Pieces don’t gain kinetic energy in a collision. Even if they collide and get sent off in an “upwards” direction, it’s not up very far relative to the orbit, and that’s just a less circular orbit at lower speed that will burn up even faster
For you scenario to work, there would have to be a chain reaction
Each chance is remote enough, and ricocheting pieces only go so far, and any higher satellites they could reach are also low orbit, that I can’t imagine how remote the chances of this happening are
Kessler syndrome is a real worry, but not in this low orbit
The satellites are constantly giving themselves small boosts to maintain orbit and then are deorbited in 5 years when they run out of fuel. It should be well less than 5 years to resolve a LEO Kessler type situation from starlink.
and isn't that a nice thought, but no, it raises orbit fairly naturaly...
