True, there is some redundancy. But the old Space Fence does a lot that no other system can. And it's cheap. It doesn't simply protect us from stray chunks of debris. Our enemies could hide offensive elements in those extensive debris fields. My understanding is that only a space fence can keep track of it all.
Another twist... The facility they're shutting down in October provides coverage for the Southern-tier states; i.e., largely Republican states. Oh, that muslim pos in the White House is vicious.
Orbits cover the whole world. The Space fence only acquires satellites that have an orbital inclination greater than about 30 degrees (i.e. tipped with respect to the equator). Still enormously cost effective.
Let’s hope Rush will pick this one up tomorrow or Tuesday.
