(Phys.org)—Engineers working on NASA's James Webb Space Telescope met another milestone recently with they completed performance testing on the observatory's aft-optics subsystem at Ball Aerospace & Technologies Corp's facilities in Boulder, Colo. Ball is the principal subcontractor to Northrop Grumman for the optical technology and lightweight mirror system.

"Completing Aft Optics System performance testing is significant because it means all of the telescope's mirror systems are ready for integration and testing," said Lee Feinberg, Optical Telescope Element Manager for the at the Goddard Flight Center in Greenbelt, Md.

Since last May, the AOS has undergone a series of thermal, vibration and cryogenic testing to demonstrate that it can withstand the rigorous vibration environment of the rocket launch and remain precisely aligned in order to function at the extremely cold temperatures in space. The AOS will remain at Ball Aerospace to be used in integrated testing with the flight actuator drive unit and AOS source plate assembly. The AOS is the final optical subsystem in the Webb's Optical Telescope Element to complete integration and test activities at Ball Aerospace.

"Each optical element that Ball Aerospace builds for the Webb is extremely sophisticated," said David L. Taylor, Ball Aerospace's president and chief executive officer. "The successful completion of another brings us one day closer to the launch of NASA's next major space ,"

The AOS is a precision beryllium rectangular optical bench that houses the tertiary and the fine steering mirror installed at the center of Webb's primary mirror. The AOS is surrounded by a shroud that eliminates stray light, and two large radiator panels that keep the assembly cold. This subsystem collects and focuses the light from the secondary mirror and feeds it into the science instruments.

In September 2012, Ball began the process of shipping the finished Webb primary mirrors to NASA Goddard. The remaining mirrors will arrive at Goddard in 2013, awaiting telescope integration in 2015. The Webb is on track for an October 2018 liftoff.

The Space Telescope is the world's next-generation space observatory and successor to the Hubble Space Telescope. The most powerful ever built, Webb will observe the most distant objects in the universe, provide images of the very first galaxies ever formed and see unexplored planets around distant stars. The Webb Telescope is a joint project of NASA, the European Space Agency and the Canadian Space Agency.

Glad to see progress on the James Webb telescope; especially after it came so close to being killed.

I have been following this project since its inception, and I am really excited about it. Imagine a very large array of these telescopes in space. The first one is always the most expensive, and others will be cheaper, but the payoff would be enormous.

I know, I'm thinking way ahead of myself. Am I crazy? Nope, not really. Of course, I'm the guy who thinks it might be cheaper to build a super particle accelerator in space. Hey, a guy can dream.

Launch sometime in 2018, then the long trip out to optimal distance for the best shots. Hopefully everything goes well with no hitches since there's no turning back or flying out for repairs.

Nope...you're lying again, Blotto. I never said that they could REdesign it. I said that they could make room for it. There's a difference. You're the one that's tardin because that's all you are and ever will be. Just a big old retard, FrankH/Blotto

And besides, I doubt those other scientists bothered to ask for their instruments to be included with the James Webb...at least they probably never even thought to do it.

There IS five years before launch, you know.

The Space Launch System will finally have a reason to exist. And if anything goes wrong , the first NEO it will pay a visit to will probably be the JWT.

Why is the pork SLS needed for this? JWST has already gone so far over budget that its destroyed NASA's space science budget for most of this decade.

natello, that is incredibley ignorant of you. are you just scared its going to not show what your aether wave theory predicts or what? even if it were to prove what you claim dont you see how that would change everything?despite your beliefs to the contrary science is not some cult that follows whats popular, it follows evidence and observation. you should be happy if you are so sure the modern theory is wrong and yours describes things better.

Nope...I have never denied being an Engineer. I earn over a quarter million dollars per year on the job as an Engineer, so why would I need to deny it?
As far as hubris, there would be no hubris needed because everyone KNOWS that it is YOU who are stupid, FrankHerbert the sock puppet. All these months it is YOU and your puppet master who were denying my Engineering profession so that you could be popular with VendicarD aka Vendicar_Decarian aka Scott Nudds, etc. etc. and, of course, your AuntieAlice_pissorg.

Now why don't you obvious transvestites run along and go bother some unsuspecting Physorg newbie so that Physorg can get a further bad reputation as your unwelcoming committee finds someone new to harass and attempt to intimidate, aye?

FrankHerbert the sock puppet of Theghostofotto1923 is a racist, a bigot, an anti-Semite, a homophobe, a congenital liar whenever Blotto feels it necessary for his sock puppet(s) to lie about people.
PLUS the sock puppet takes parts of comments out of context, twists the meanings, truncates them, adds words or letters, removes words or letters, and likes to be an asshole in general...all that under control of the sock puppeteer, Theghostofotto1923 aka Blotto, who also does all of those things.

According to a female commenter, (Pussycat_eyes), FrankHerbert/Theghostofotto1923 is suffering from DISSOCIATIVE IDENTITY DISORDER aka MULTIPLE PERSONALITY DISORDER, which is a mental disorder characterized by AT LEAST TWO DISTINCT and relatively enduring identities or dissociated personality states that alternately control a person's behavior, and is accompanied by memory impairment for important information. FrankHerbert/Theghostofotto1923 has many more than two sock puppets.

Obiewan/pussytard the fake NASA engineer (contract) says:

Well sure, because any real engr would know that this would require REdesign of power, software, weight distribution, propulsion, etc. And as most people would understand, it is far too late for this.

Last time you brought this bullshit up I decided to email someone at NASA, and got this in response: 

"Description: No, Webb is well past the planning stages and into the building stage. From: OPO Outreach Sent: Wednesday, December 12, 2012 7:09 PM To: --- Subject: hubblesite.org support ISSUE=4385 PROJ=13: A HubbleSite 2012-12-12"

-which many people told you, and which you chose to disregard, because that's the kind of imbecile you are. And so more proof-positive that pussytard is only an engr of outrageous lies. Don't bring it up again.

I wrote my buddies at NASA about puttin a teledildonics module in the James Webb telescope. The best way to make peace with the 100 foot tall glass martians is to put it in there butts. That always worked for my sons at least.

The dummies at NASA acted like I was crazy. They know this is a good idea, but they want to take all the martian tech for themselves.

And I have already said that they could have made ROOM FOR IT, but evidently the researchers failed to ask that their own instrument be included with the JWST.

Yeah Blotto. I suggested the idea to obama_socks and she ran with it! Those jerks at NASA just don't understand how to conduct science. The female commenter Obama_socks agreed with me it'd be a good idea and asked her buddies at NASA, but they say it's too late. BS it's not even built yet. Of course they have time. . . .

I'm sure they're afraid of what they'll find.

I see that Theghostofotto1923/FrankHerbert has brought in another sock puppet he calls RitchieGAY01 to further deteriorate this thread...and the website.

It's well known now by all those with a functioning brain that:
"According to a female commenter, (Pussycat_eyes), FrankHerbert/Theghostofotto1923 is suffering from DISSOCIATIVE IDENTITY DISORDER aka MULTIPLE PERSONALITY DISORDER, which is a mental disorder characterized by AT LEAST TWO DISTINCT and relatively enduring identities or dissociated personality states that alternately control a person's behavior, and is accompanied by memory impairment for important information. FrankHerbert/Theghostofotto1923 has many more than two sock puppets/identities."

Pussycat_Eyes told me in a PM that she has given birth to her first child and no longer uses her Pussycat_eyes user name due to Theghostofotto1923 and his sock puppet, FrankHerbert constantly harassing her. Blotto the clown thought that Pussycat was somebody named Ritchieguy.

No you said they had plenty of time to add instruments to the Webb which, obviously, they didn't. ANY engr would know this. ANY engr would instantly recognize you for the liar that you are.

Look what you've done to this thread. You drop turd after turd with your Ritchie sockpuppet. You dirty up every thread you choose to post in. Does this make you any less ignorant, any less wrong, about the nonsense you post? What makes you think you BELONG here pussytard?

And you're a LIAR. This is obvious with everything you post.

-Harrassing pussytard? You post bullshit, you lie, you flood, you vandalize. People take exception to this. How is this harassment?
