[George W. Bush]

There is a Soyuz attached to ISS as a lifeboat. They will probably launch another for backup when they evacuate the crew. It could spell the end for ISS because the shuttle is used to boost the orbit of ISS periodically. It is in a low enough orbit that there is drag from molecular oxygen that exists at that altitude and the effects of gravity.

Any figures on how soon we must boost the orbit? Any of the Soyuz's capable of filling in for orbital correction?
