From what I understand, the space station is necessary as a means of studying the long term affects of the human body in zero gravity. There's no point in spending billions and billions to build colonies on mars if our current science means we can't survive in space for more than a year.

It is my impression that NASA scientists aren't as interested in the ISS as other missions and feel that it is taking up way too much budget for too little return. I don't however wish to speak for these people and may be wrong (but I work with some of them).
