in the whole thing about Obama wanting to clip NASA's wings and push privatization of space travel, no one seems to be asking the obvious question:  what if there IS no way to run a profitable business around human space travel / going to the moon?  Or, what if it's going to require another 50 or 100 years of technological advances <i>by government space programs</i> before that becomes commercially viable?  Even if you are for commercialization of space travel, you ought to be against what Obama wants to do here, because it's possible we could be pushing the commercial human space travel baby bird out of the nest 50 years too soon and shooting the mother.
