Good stuff!

I suspect you would enjoy Zimmerman’s blog; he covers space/science, and politics, with a strong free-market political bent.(He’s also has regular appearances on the John Batchelor radio show.) (He’s not Bob Dylan, George Zimmerman, nor the leftist hack, of the same name.)
I go for the Space stuff, and hang around for the politics.

Yeah...
It was. Can’t deny that.
And it was a Big Government Project.
I believe it was Perkins-Elmer who did the mirror, and they had an exemplary record of grinding mirrors.

Go to this point in the video:

for a discussion on how the screw up in grinding occurred.

Thanks for sorting that out! The metric error was on a Mars mission. I'd forgotten about the shim and conflated the two spacecraft -- in my 80+ year-old memory... '-)

Maybe the Hubble correction was via the secondary mirror mount. Now, I'll have to go look it up...

Well, I did look it up -- and there's a fairly good article on the fix[es] -- at CBS, of all places:

https://www.cbsnews.com/news/an-ingenius-fix-for-hubbles-famously-flawed-vision/

...even if CBS can't spell, "ingenious"... '-)

My 80+ year-old memory bank was faulty: They did mess up the main mirror! The article linked in my #26 sorts it all out...

I still believe that the hubble is a 1980’s spy satellite pointed outwards.

You would have been right but it wasn't any big secret.

Was it really necessary to excerpt this short blog post?

The Hubble telescope proves out Psalm 19:1 “The heavens declare the glory of God” by discovering beauties never before seen by man.

Hubble is being replaced by the James Webb telescope.

My son is about to graduate as an aerospace engineer. Several of his friends are working on the Webb project.

I’m right behind you ever step of the way! (I’ll be signing up for social-security very soon.)
I did go through Zimmerman’s presentation again and linked to the part where he explains what happened, in a different post.
—the error configuring the “null corrector” device, amounted to “1.5 millimeters,” and the rest, as they say, was history.

It points to an 80 minute video...

Absolutely!! In fact, that very verse is the climatic statement in my

"The most outrageous claims ever made"
A Physical Scientist looks at Genesis..."

...a computer graphic presentation that I'm now in the process of converting into a narrated video...

~~~~~~~~~

(That could read, "A Christian, Creationist, Physical Scientist...")

Interested?

Absolutely. Given my son’s burgeoning space career, my wife has been developing an interest in astronomy and we’ve always believed in young earth creationism.

(One of my other kid’s started CDL training today. Now I need to get her to understand the difference between a Kenworth and a Peterbilt)

We even had the opportunity to host an eclipse party for 200 people.

That stuff is always interesting.
