Apollo was a national security project -- demonstration of our system, exploration of technology of potential military importance. Fixing Hubble was really important. I'm not sure how much the shuttle's work was of the same magnitude, or couldn't have been done with automated gear. BUT bureaucratic and political imperatives called for continuation of the space program, at scale, and that called for justification of the costs. The money is no big deal, but if those justifications aren't that good, the collision of those weaknesses with the human risks will cause cognitive dissonance. If the people concerned haven't the will to rethink the whole thing -- and there are many examples of much, much larger failures -- you're going to see some strange behavior along the way. Shuttles failed twice in 100 missions, is the milestone of first senator in orbit really worth a 2% fatality risk? No, but rather than admit that and cancel the mission the response is to imagine that risk can be driven down to negligible. And if that isn't possible, the standard is going to shift from "known but justifiable risk" to "we're doing the best we can / no expense has been spared". Of course it doesn't make sense. But if they recognized that, they wouldn't have flown such missions in the first place. |

Although a staunch supporter of Zubrin and his Mars strategy, as well as a supporter of the HST maintenance effort, I think he shot down his own proposition in this particular article. He points out that Hubble cost $5 billion, while elsewhere, he casually mentions that each of the 125 Space Shuttle launches cost $3 billion.
So for the price of just one additional Shuttle launch, we could've simply launched a new (and potentially improved) copy of Hubble instead of risking anything at all to fix the old one. That's what I call a no-brainer.
