Some orbits are quicker than others. Cloudsat was recently retired, and was lowered to a graveyard orbit which decays a lot more quickly. As I understand it, our collective space programs have made a bit of a mess of operational orbits and we need to think about cleaning up debris while also mitigating any future additions to the debris field.
