Actually because of the mirror flaw the software was not able to achieve a focus, at least that is what we were told.  I still say that the mirror was fine when pointed at the Kremlin which was the purpose.  But people like you think that blurry images of nebulas were important

Can you explain how it is possible for the earth to be in focus but not the stars? Optics with misshapen lenses are no good at any distance.

Hubble was a camera the mirror was only one part, lenses and computer software and a CCD were all required for focus and image capture

No.
When you write "Next" like that you have to have answered the question, and you didn't
If it was broken, how did it work?

LOL exactly what are you hoping to achieve here, and why is this so important to you?

First thing who are you talking to and second even if it wasn't important to us it sure sound like it is to you.

[Bored chemist]

Science, because this is a science page.

Can you answer one simple question before you go?

If the US military wanted to build a damned great spy satellite, why would they bother to lie about it?
Much better to brag about it- to tell the Russians to be careful or we would post pictures of their bald patches or something.

Why pretend it was a telescope?

Do you have old water pipes at home or is there a possibility that you're getting heavy metal poisoning from somewhere else?

You forgot to answer the question.
Please pay attention, Adderall may help explain your delusions.
or, of course, you might actually be old enough to call me "son"- in which case I will assume you are senile.
The point remains, Hubble was a telescope, and they buggered up grinding the mirror.

It could not have been a spy satellite.
It was in the wrong orbit- too high and moving too fast- too blurred.

He probably doesn't read it outside...

You can not put a big satellite up there without the Russians knowing.
If you as just some ill-informed nobody on the web think it might be a spy camera than it's sensible to recognise that the Russians might think so too, and make sure they read the post in the office rather than the garden.

You are probably correct, but you still do not tell your enemy how your secret spy systems work.  Does your country work like that?  Are you sure.

Logic works, try it sometime

Why should I?
It's not as if you do.
You keep ignoring it.
Your still trying to insist that Hubble was a spy camera.
But it can't have been.
Logic proves that.

[Bored chemist]

you still do not tell your enemy how your secret spy systems work.

Do you mean, you don't give them high definition video  images of you installing it?

If there was any chance you were right then the Russians would have been looking very carefully at that video (and the others).

Your right about logic.
Logic tells you that satellite wasn't a secret.

Actually open secrets and or one thing posing as another are quite common in espionage.

I presume you remember the glomar explorer's foray into manganese nodule mining on the seafloor that was actually project azorian

LOL now tell us that Hughes was really seeking manganese

Wheeeeeeeeeeeeeeeeeeeeeey

As I understand it, the Hubble chassis and mirror were leftovers from an obsolete US spy satellite program. Space programs always keep a model on the ground so they can debug problems experienced in orbit. When this reconnaissance program was superseded, the ground model also become surplus to needs - so they offered it to NASA.

I understand that a similar offer was made more recently to NASA, when the subsequent spy satellite ground model also became surplus to needs. However, NASA was more interested in infra-red to see the early universe, stellar nurseries and the center of our galaxy, and went with the James Webb space telescope design instead. James Webb is to be launched later this year, hopefully..(it is now too expensive to be abandoned!).

There was definitely a problem in grinding the Hubble mirror for its revised mission. Apparently, the military has equipment that could have measured the mirror to the required accuracy, but NASA, as a civilian body, was not permitted to make use of it.

Actually the American military does not make mirrors, in fact the American military really does not make anything, military contractors do the construction to military standards.  So the measuring and grinding has nothing to do with the military though they might set the parameters for what they want or need

[Bored chemist]

Actually the American military does not make mirrors,

You do realise that nobody had said they do, don't you?

[Bored chemist]

The Hubble mirror was the highest optic ever put in a spy satellite

Highest is a good description.
It was the furthest from earth.

Which is a really stupid place to put a spy satellite.
If you want to look at something you go near to it rather than far away from it.
