No. Not in the sense that it would sit in Hubble-type orbit for a year while it's tested, and astronauts go to turn wrenches and adjust things that aren't right. And yes, I suspect that would much more than "a bit of extra time and effort." It's probably completely at odds to being launched to L2, and would be an incredible cost and complexity adder.
But it has pre-flight testing and a lengthy in-space verification process as it reaches L2.
Actuated primary mirror segments, actuated secondary mirror, and a wavefront sensor system enable it to self-align. While it's much more complicated, and unreachable for servicing, it's also much more flexible for on-orbit self corrections.
Ooh! Look! They've invented paper and the $0.99 solar-powered calculator!
HP's already announced and seemingly canceled amazing new Win7 tablet. They've bought WebOS and then suggested that they're going to stuff it in printers, so forget about tablets for now. So what are they doing here? More stuff that doesn't exist or won't leave the lab? Or won't be sold until I've already bought my iPad 2?
Why don't these companies mimic Apple where it matters? Don't rumor, tease, prototype, spin, et cyk? Shut up until you've got something work talking about...and then release it!
While you're right that NASA use of Mac OS X is much higher, it's not true industry wide. The *only* people with Macs are the NASA employees. Everyone else, working at conventional companies like Boeing and Northrop Grumman use PCs.
This is not good or bad, it just is. NASA gives their technical people significant freedom in choosing their computer and software. But it's atypical. Everyone else buys Wintel systems.

From the article, "This month, ITT Corp. in Rochester, N.Y., demonstrated robotic mirror installation equipment designed to position segments on the backplane."
I'm pleased to say that I was one of the individuals giving that demo to the JWST review team:) And kudos to the team for assembling quite the system for integrating the segments.
Yes, we've considered it. And dismissed it. This is obviously not a PR stunt by Apple. They don't do early reveals on their hardware. They've not revealed the past three iPhones. They didn't clumsily leak the iPad's design. It's obvious they don't care or need to leak in on the 4th iteration of iPhone, a device that's guaranteed to be a success.
And when they do leak info, it goes to the Wall Street Journal or The New York Times. It doesn't go to Gizmodo.
Unfortunately the article gets the technical aspects wrong.
NASA is not "freezing" the mirror segments to make sure they "survive" space.
The JWST will operate at a cryogenic temperature in space. The mirrors are measured at cryovac to guide the manufacturing process so they will have the correct optical prescription at the telescope's operational temperature.
Similarly, we're testing support optics, for the pre-launch JWST testing, at cryo. We'll have the first of a one set down to temp in short order.
By "downfall" you mean 60% increase in stock price YTD? Or by downfall you mean Apple's record profits last quarter? Or is their 90% ownership of the over-$1000 retail computer market?
By all measures, Apple's "downfall" of selling expensive hardware is anything buy.
It's a new technology promising lower cost and higher sound quality than the current digital downloads. It employs state of the art lossless audio encoding, capturing sonic signals beyond human hearing. The promoters also boast every purchase comes with a free archival system, so if your digital version is lost, you can trivially recover it. Even more amazing, it has absolutely no DRM!
This technology is bleeding edge, and so far ahead of the current lossy, non-archived, unshareable digital dreck, it's no wonder a kid wouldn't have heard of it.
Where is said the information is "classified"? This may be ITAR controlled data, which is not classified.
There is a broad range of information which is not classified, which is not trade-secret, which can be discussed openly...but never with any foreign persons.
It has a good deal of security theater. Data can and will be granted export exceptions if that exception is needed to get the work done for, say, NASA. So it's export prohibited until it must be exported to get the job done, and then it's not export prohibited.
It has been enforced with vigor not seen for about 30 years; the aerospace community hadn't really heard about nor cared about ITAR until about six years ago. And they didn't care about it until ITT was walloped with a $100M fine in 2007.
Seriously, a wifi-equipped laptop can be had for less than $400, and with a 15" screen and decent internet access, why would someone want a limited, single-purpose crippled cellphone such as a you buy for $50 at Verizon?
Seriously, a hammer can be had for less than $10 and can effectively pound a fastener through any amount of wood? Why would someone want a limited, overpriced drill?
And this is how ITAR is damaging to our national security. As the DOE and DOD are major funding agencies at universities and national labs, we are now creating a research system that prevents foreign nationals from participating. And since they are a large percentage of our grad students, that's a major problem. It subsequently makes the US a less enticing place for the skilled students we'd like to immigrate here.
If this is ITAR and not classified data, then there may not be the signing of voluminous forms. ITAR just is. If your company is on top of it, then the staff will get powerpoint briefings about it. But there aren't signatures and forms and etc.
And everyone is liable regardless of whether they've heard of ITAR, had the powerpoint briefings or don't even work in defense industries. If you, say, bought a bulletproof vest from eBay and then traveled to Mexico you'd be guilty of an ITAR violation. (real example)
The rules have changed. It is now illegal to "export" ITAR data, that is "sensitive" defense technology to foreign persons. However, this data is not classified. You can tell it to any and every US Person: your friends, family, neighbors, convenience store clerk. SO long as they are a US Person and also know not to tell it to Foreign National, they can know it.
However, telling it to a Canadian can get you sent to prison.
The rules have changed. And it's damaging to critical industries and research institutions.
"keeping the signal locked,..., doesn't always work. My Gnome desktop has blinked on and off a few times, inexplicably; a "Searching all signals" message appears on screen, but it only manages to automatically recapture the signal about half the time....... the lamp will cycle through several colors and brightness levels. Sometimes this is fleeting -- just a momentary change -- but sometimes the image takes on a new hue and stays that way for minutes."
The projector doesn't work correctly, sporadically dropping the signal and randomly changing color temperature...and it's given an 80% grade? What sort of nonsense review is this?
Who is this review for? Who pays $500 for a dim, low resolution display to watch movies or surf the web? For the same price you can get a 22" - 36" 1080p display for home use, that shows a consistent, quality image. For the same price, you can buy a portable projector, that works properly, for professional presentations.
Because that is impossible. We do not have spaceborn manufacturing facilities, period. Not for paperclips and tennis shoes, much less for a novel space telescope.
There have been interesting proposals for lunar telescope manufacturing facilities, but that is science fiction for now.

For full effect, you need Raymond Scott's Powerhouse playing in the background when watching this (or any other) Rub Goldberg machine.

You keep using this word "digital". I do not think it means what you think it means.
That's not how optics work. You need to image what you want to see onto your detector.
To test this: remove the lens from your DSLR and take a photo. You'll get nothing but blur.

JWST has spectroscopy e.g. NIRSPec = Near Infra-Red Spectrophotometer.
The JWST is more about massive light gathering (seeing closer to the dawn of the universe than ever before) than pretty visible-light images.
They're not. Just the one.

You're buying outdated, conventional desktop platform for kids that will be developing on Mobile / Touch OS systems in 8-12 years.
That is, you can't predict the future, so get an appropriate system to teach them fundamentals, problem-solving, and some immediate skills.
While you're right that NASA use of Mac OS X is much higher, it's not true industry wide. The *only* people with Macs are the NASA employees. Everyone else, working at conventional companies like Boeing and Northrop Grumman use PCs.
This is not good or bad, it just is. NASA gives their technical people significant freedom in choosing their computer and software. But it's atypical. Everyone else buys Wintel systems.
