Skylab went up complete in one launch, and the ISS is still only partially completed after how many flights? But Skylab was not very well set up to do materials sciences, and it was more of a promotional program than a serious, long term approach to space science. My impression from the whole thing, looking back on it now, was a subtle attempt to blackmail Congress into shaking loose some more money. If they got the thing into orbit, it would have to be taken care of, and no one could imagine Congress just turning its back on a space project. But Congress did, probably in part out of angst that NASA didn't really go through all the proper channels to get Skylab off the ground.<br /><br />Instead of requesting funding from Congress, NASA just cobbled together what they could out of spare parts, off the shelf equipment, and modified systems originally meant for other applications. So, it came as kind of a surprise to Congress when NASA announced that it was launching a space station. I think that NASA hoped that Skylab would be like a big bill board, saying "Hey, everybody, we're still up here!" But, the U. S. had Disco Fever at the time, and wasn't paying attention. <div class="Discussion_UserSignature"> The secret to peace of mind is a short attention span. </div>
