Re: Columbia to ISS? But I thought.....
Columbia will be outfitted with the just about the same equipment setup that was used in the Shuttle/Mir program. It has enough performance margin to get a light truss segment up to ISS. On STS-118 it'll carry the S5 segment and a SpaceHab single module carrying supplies. Columbia can also be used to carry SpaceHab double modules to ISS on logistics flights.
