Out of curiosity, what method is used to keep the International Space 
Station from burning up?

I know that periodic boosts are done to raise the orbit.  Is that done 
with rocket engines built into the space station?  If so, it seems that 
storage and eventual reloading of the fuel would be difficult and high-risk.

Or is the ISS boosted using the engines of a docked vehicle?  That seems 
like it would have its own set of complications.
