Why can't they track this school bus sized satellite?
As I understand it, yes they can track tiny objects, but not on every orbit.
have 20 radar units around the world, but they have to
wait for an object to pass over one before they can check its position once more.
If, hypothetically, UARS did not pass over any of those 20 stations on its final orbit, they're just in the dark as everyone else.
