mknewman writes to tell us that NASA is no longer receiving data from the Hubble Space Telescope, which could possibly delay the shuttle launch planned just two weeks from now. There is a backup system installed which may be used instead of training the astronauts on the installation of the new component, but that would itself leave no fallback option. "NASA is reviewing whether the mission should be delayed a couple of months so that plans can be made to send up a replacement part for the failed component, said NASA spokesman Michael Curie. It would take time to test and qualify the old replacement part and train the astronauts to install it in the telescope, Curie said. NASA also would have to work out new mission details for the astronauts who have trained for two years to carry out five Hubble repair spacewalks."

They only know how to fix old Russian satellites, so they would have to be completely re-trained to handle the Hubble. Besides, we'd have to send a rocket all the way to the moon to retrieve Tommy Lee Jones after he rode the other satellite there.
Of course, he's probably been captured by the moon men and made to toil in their underground mines by now, so trying to get him may end up being more trouble than its worth.

I'm sure they did the equivalent of "thwacking it". But the "thwack" repair method seldom lasts long.
"Thwack it" is for things like the martian hoopties Spirit and Opportunity ("Hoopties" because they're WAY out of warrantee) that you can't send a mechanic to fix.
Or us rednecks with broken cars and even broker wallets; I fixed a heater hose with duct tape on a '74 LeMans, and it still held leak-free when I sold the old junker three years later. You don't fix Rolls Royces or Hubble Telescopes with duct tape!

I actually used duct tape on duct, once. I was venting the propane gas drier outside for a buddy of mine and had none of the 100 MPH tape. The 100 MPH tape is essentially duct tape on steroids. I could be biased but I have used both commercial and military and, well, I have to say that the difference is obvious to me at least. It is VERY sticky and VERY strong compared to the stuff you get at your local hardware store. Again, that could be observational bias, it's not like I've stress tested the two under various conditions to see the result and measure the result or anything...
Oddity note: Once I was out of boot I would leave a small piece of this tape on the stock of my rifle. It allowed me to put my face to it and feel where it was and get into a firing position more quickly and accurately. The subtle feel was enough, my rifle was sighted in at 500 yds and, it is hard to explain, to feel where you *should* be without needing to sight in (like you'll have time for THAT in combat) to adjust for a shorter or longer range is... Hmm... Almost like magic except nothing like it.
Err... I drove maggots around and brought the maggots supplies while they were shitbags in OCS. (Later they'd be my leaders.) It was a near constant that I had to be able to hump 20 miles, show them how to get unstuck without a tow vehicle, bivie with them for a few days, and constantly have to prove how a "Real Marine" was prepared and could fire his rifle better than the maggots and shitbags. (Maggots earned their way in. Shitbags earned their way in but came via nepotism. "You are not your daddy's sperm shitbag! Did you fuck your daddy to make you? Did you fuck your mother? No shitbag? Well the whole platoon is going to fuck her tonight shitbag. While you watch. I'm going first, let's see if you can build some muscles up shitbag. Drop and give me fifty." OCS in the Marines is probably not what people expect.)
Sorry - I came back before hitting submit in an attempt to see if I should censor the text above. I opt not to. As tempting as it is to not offend I am more willing to ensure that the historical value (if any) remains true.
We put splints in place with this tape. We held things meant to make loud booms together with it. We taped maggots to hot steam pipes when it was suggested we do so with it. (You can tape a maggot - you can not tape a shitbag. Yes, this is hazing, yes this is the Marines. Yes, I think that this was required. Don't like it, don't serve. 'Snot PC or anything but we need tough people making tough choices at a time when failure is not an option.) There are stories of patched airplanes and there was a story floating around about a patched chopper rotor but, frankly, I don't believe that one.
Anyhow, I have rambled on long enough but want to continue for a moment. I apologize, ahead of time, for having taken up your time with the post but it seemed as good a place as any to ramble about it. I have some strange (by many opinions) views of how things should be. When we picked up new medals, awards, ranks if you will we had a ritual. The blouse was worn as all Marines wear it but the people getting their medals (think the pins that have backs on them) would stand there. First the issuing officer would give you the backs to the medals. He'd then take the medal and *press* it into you. He was gentle. You would remain at attention for this. The remainder of the squad would then come along and PUNCH that medal into you. Yes, meaning you pried it out of either bone or tissue when they were done. And you did so with pride. And you did so while remaining at attention. You look beyond the people, you look beyond the pain.
To most who haven't served that would seem barbaric. Indeed it is. Having "punched chests" and had my chest punched enough I can assure you that I never harbored any ill will towards those doing so and, in fact, I believe I am stronger for it. If one can't handle that then it is my belief that they don't belong in the Marines who's job consists of killing, dying, living through pain, and being first and foremost a rifleman.
This is now way off topic but I figured I'd better explain the latter so that the entirety made sense.

Almost three years ago, our dishwasher (which was only a year old at the time) stopped working. After a bit of troubleshooting I determined that the solenoid valve in the water intake was shot - my multimeter indicated that it was receiving an electrical signal, but the valve wouldn't open so the dishwasher couldn't fill.
I whacked it with a hammer and it's been working flawlessly ever since.

This is just bullshit.

They have a backup, that's what it is there for. And this is hardly a high failure rate, we have already gotten more than it was designed for.

With the impending lapse of manned flight and a potential to not have access to the space station I worry that we're falling behind. If, for no other reason than moral, we needed the space program at first. Today we need it just to keep up.
When I was a kid the entire family or the entire school would gather around to watch the launches live. Today you seldom get those launches on your major channels and the only coverage is failure. I don't know how many people who've said stuff like, "We don't need a space program." Granted, these are likely the same people who say stuff like, "Let's bomb Iran next, serves them Arabs right." The problem is that they vote and are allowed to.
I hold a special place in my heart for NASA or space programs in general. You ask a kid what they want to be today and they want to be a rap star. When I was young we all wanted to be astronauts. The only time they see or hear about space is when goes wrong or, worse, blows up and kills people.

As has already been noted, NASA's failure rate isn't really that high. If anything, it may be the reverse: NASA has become so risk-adverse (it's argued) that the public has forgotten how *hard* space is and it starts to seem boring. (And like a good idea to raid the NASA budget for other projects because they appear to have more than they need.)

I was just thinking that it was so lucky the part failed TWO WEEKS before the last repair mision ever was going to be launched--and lucky that the part was not needed for the safe operation of Hubble. It would have sucked if Hubble had to be de-orbited right before the repair mission. Hopefully, the gyroscopes and other parts necessary to keep the Hubble safely in orbit hold out until the makeup repair session.

Saying "Interferometry can do better" makes no sense... similar to saying "RISC can do better" for you computer geeks. It's basically jargon + the phrase can do better. Meaningless without a problem statement and a lot of background info.
In reality, very few optical telescopes can operate in an interferometric mode, and there's a specific class of problems where it's actually useful. Furthermore, I think it would hard to define "better" in this context. FYI there are also preliminary plans out there for formation-flying interferometric space telescopes (none are currently on the map for real funding AFAIK).
In terms of absolute resolution over a small field with just a single telescope (non-interferometric), ground-based Adaptive Optics *can* do better (under certain conditions)... in the near future, they will be able to do significantly better than the Hubble over a much larger range of conditions... -But- there are still PLENTY of things that ONLY a space telescope can do, a buttload of things it does "better", and tons of interesting science that remains to be done.
