I disagree. It's well-documented that Bush's advisors wanted a "Kennedy moment", and felt that a big announcement that Americans were returning to the moon would be good PR, even if it never panned out. Constellation was an incredibly cynical marriage of political hacks in the administration and NASA administrators desperate to preserve the glory of Apollo. Constellation was dead in the water when public reaction turned negative, even if no one in NASA was willing to admit it. Also, I hold to my opinion that manned spaceflight has produced nothing of scientific value. I'm sure you could come up with the odd technology here or there, but after fifty years it's hard to point to any significant technologies that came out of human spaceflight, much less advances in science. All human spaceflight teaches us is how to put men in space. I'm not suggesting that NASA's budget should be cut, but they should be spending that money on missions that produce real results, like the Mars rovers.
