Most likely no one at "SPACECOM" is going to lose a job. AFSPC, through the Space Surviellance Network tracks 10,000+ objects. That is not everything up there, just the stuff they can track on a regular basis due to size, reflectivity, orbit, etc.

So they are tracking it, how to do predict potential collisions? You "fly" the orbits out days in advance on computer systems to look for close passes, then you keep an eye on those. The problem is you cannot run these predictions for everything. The permutations with 10,000+ object, even with altitude and orbital screens takes huge amounts of time and computing power. Screens can be done, but often only for high priority satellites.

So why not Iridium. Don't know if they screened or not. Something to think about though is the legal and financial liabilities the government could get into if they were screening privat civilian satellites. What if the gov't said there would be a collision, so a private company moves a satellite. Then come to find out the orbital predictions were off, there never would have been a collision. Is the gov't now fiscally liable for the loss of satellite life due to fuel expenditure on an active satellite? I bet the civilian lawyers would say yes. What if the gov't, providing screens, missed a collision? Is the gov't now liable for that? These are real questions that come up when gov't agencies provide support to private companies. They can be overcome, but processes, data clearinhouses, etc have to be established. Those cost money. Who is going to pay?

Get the idea?
