Fascinating and something I hadn't thought of at all. Basically we're putting a lot of metal up into LEO, and it's shedding particles, and those are metal particles - compared to the atmosphere, which is gas. This stuff is not there normally, and nothing like it before has been known. It's a bit like putting 100k+ small metal asteroids into orbit, and finding out what happens. LEO megaconstellation are going to profoundly change LEO environment.
