The lower your orbit, the quicker your orbit decays due to atmospheric drag.

That’s the problem here though, that effect is lessening. So they’re gonna stay up their longer, potentially past the limits of what they can do to avoid collisions. That’s going to create problems for lower orbits.

Not exactly. If it goes into full blown Kessler syndrome, it will become everyone’s problem, including at the newly “freed up” lower orbits.

It’d probably run at a cool 60 mpf

Hell yeah

Pretty neat, but probably not something I’d buy
