> So stupid question but I guess it isn't worth it to somehow push them up with small corrections/booster-like things? At least to save it for a few more years?
Yes, they send them up with a certain amount of propellant to do that, once that runs out they fall down.
> What happens when they fall? Do they more or less burn up?
Yes. They're small enough to burn up completely, and low enough to do that quickly rather than creating a space junk problem.
