NASA Didn't Decide - O'Keefe Did (Score:5, Interesting)
In typical cya fashion, O'Keefe called on Harold Gehman, who led the Columbia accident inquiry, to review the decision. It's a bit of neener neener on O'Keefe's part because Gehman's commission nailed NASA for sloppy safety management policies.
What O'Keefe is saying to Gehman is "Look you SOB - you try running an agency that's being pulled 20 different ways and see if you don't start cutting corners."
Problem for O'Keefe is that there are plenty of ideas [nytimes.com] on how to both service Hubble and adhere to the Gehman's commission's advice. Not surprisingly, NASA management choses to ignore its engineers [nytimes.com] instead of listen.
Nasa will be well rid of Mr. O'Keefe when he leaves. Next time, maybe the powers that be will appoint someone with an engineering background to run the agency.

I'm all for space-endeavour and for satisfying the human spirit for exploration, but I fail to understand the merit of a kennedyesque initiative that cannibalises a fully functional golden goose.
And if you want to talk about the risk of using the shuttles to service Hubble, the shuttle's terrific performance record itself should be enough to catch you on the wrong foot. Given the high complexity of these missions (we're talking "rocket-science" here right?!), the risk has clearly been marginalised given that only 2 out of 100+ missions have failed -- and those too out of an avoidable complacent attitute to safety at NASA itself.
When Columbia was lost, it was followed by a constant banter about the changing culture at NASA, but if they've changed, it only to now wear their complacency on the other foot. It's apparent that they have graduated from risk aversion to planning short sightedness.
How else can you explain the fact that they are "shying" from spending a few hundred million dollars to extend by a significant percentage the life of a mission that they have initially spend billions to get rolling itself. If NASA had a wife called M@ry, I can just about see M@ry being called upon to bring the shotgun so that her hubby can shoot himself in atleast one foot.

After the CAIB, he was blasted, questioned and doubted to no end, so what does a skilled polititian do? cut your losses and move on. Well, he did just that. So now he's gonna follow the CAIB like it's the road to salvation. To the letter.
The CAIB puts forward a number of requirements for shuttle flights, including the ability to service the Shuttle via ISS if something goes wrong...among a host of other "inconvenient" requirements.
O'keefe decided to follow the CAIB to the letter so that means that going to the hubble will "break the laws" of the CAIB (Hubble is in an entirely different, incompatible orbit...still you'd think that being the thing called SHUTTLE it shouldn't be an issue, but it is)
So servicing the Hubble will violate his mandate to play it safest and thus it won't happen because it's "too risky" according to the CAIB mantra.

Do you continue to pour money down an ISS rat hole that has delivered ZERO peer-reviewed science, has no reason to exist other than pork barrel or do you allocate the flights to maximizing the remaining science?
NASA has already killed Compton, is on its way to killing Hubble and you think O'Keefe and gang will fund Webb? Perhaps you didn't notice, Webb has already been scaled back twice - the ISS money vacuum will continue to wreak its damage. Other posters have already pointed out that Webb and Hubble are not interchangeable - they see different spectrums.The problem is is that NASA will continue to lose public support if its only reason to exist is to fly the Shuttle back and forth between ISS. The ISS has no value other than job creation. Hubble on the other hand, provides both jobs and real science - the kind of science that gets published in Science and Nature. ISS science is the kind of science you find at the local county science fair, i.e., "What color does my dog like?"
Your post and O'Keefe's decision to kill Hubble clearly illustrate how poorly educated this country is. Equating Hubble and Webb and choosing ISS over Hubble are examples of what happens when half our children aren't taught science well enough to know that it takes a year for the earth to circle the sun. The cost of that poor education is you get people like O'Keefe running Nasa and the public doesn't know enough to say boo about it. We've lost the super collider, we're going to lose Hubble, 50/50 Webb will not fly, manufacturing, accounting, customer service and software have been outsourced but we'll have a worthless missile "defense" and plenty of boobies on fark.com.

Anyway, IIRC, it was the testing equipment that led to the problem with the spherical aberration. Ie, they ground the mirror to a very high standard. They fine-tuned the curvature with testing equipment to get it to the proper shape (talking 10's of nanometers of material to grind away here, not much material at all). It was this testing equipment that was miscalibrated. But it was a systematic error, so they could perfectly undo the aberrations introduced into the mirror.
As far as testing it before launch, I beliebe there were some problems that it couldn't be tested until it was in a microgravity environment. For example, the weight of the mirror in a gravitational field distorts it significantly that it can't actually focus.
