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.
