They say that no question is a dumb question, so here goes - since I  
haven't seen this discussed before, but maybe I missed it.

What makes AO-7 so special?  Why is it that we lost AO-10, AO-13 and  
all the others in the past several years, yet this one is still  
working?  I know the batteries are dead, but I'm primarily interested  
in how this bird is able to stay in it's orbit for over 30 years?  And  
if it's orbit is decaying, how is it that it has apparently decayed so  

I was under the impression that unless a satellite is occasionally  
'boosted', it will eventually re-enter?  I somehow doubt AO-7 has any  
fuel left in it's boosters; if it had any.
