Hubble Space Telescope Disaster #shorts

I recall a few claims from the time:
Even with its suboptimal optics, the telescope was producing the best images they had so far.

The mirror was distorted less than the thickness of a human hair.

One test exposed the mistake, but was rejected because the test was considered secondary and less reliable.

It would have been cheaper to build a new Hubble telescope and send it up via unmanned rocket.

Software was being developed to undo the effects of the mirror distortion.

I can imagine the day they found out the problem:

'After so much money and time to do this, we can finally....wait why is the picture like this, who was in charge of the mirror? TED GET IN HERE NOW!'

"way back in 1990" That gets more painful to hear every year...

Not even the half of it. Hubble’s launch into space was delayed by seven years largely due to the Space Shuttle Challenger disaster. Hubble was initially supposed to launch in 1983 but didn’t until 1990. Hubble had sat in a climate controlled warehouse that entire time with its faulty primary mirror.

The repair mission was carried out in 1993. Thus Hubble has been in operation for 30 years.

The faulty mirror was traced to a testing rig that had been incorrectly “fixed” with a washer.

Whoopsie doodle just became my favorite expression of lament.

The mirror was manufactured in Detroit at the Ford Motor Company and it said, "Objects in mirror could appear closer."

Hubble really was one of the best ROI's the US Taxpayer ever got.

Primary mirror was made incorrectly by (I think) Perkin Elmer. Kodak was contracted to build a second mirror as a backup but they flew the PE mirror. To this day they have never revealed if the Kodak mirror was correct or not.

Storey Musgrave was the main astronaut who installed the fix in an hours long spacewalk. Very brave and capable man. I wish I could have met him.

Part off the reason development and construction of James Webb took so long. It is beyond the reach of any repair missions so everything had to be perfect at launch

[rtmsound]

The main mirror was off by 1/50 of a human hair. Tinsley Labs in Richmond CA made the corrective mirrors in the replacement camera package.

The headlines read "the trouble with Hubble"

[turbocoupe]

They didn’t account for earths gravity when grinding the mirror, so when it was in zero G it’s shape changed .

“Ingenuity” and “Perseverance” I see what you did there. 😄

NASA engineer: Who put the mirror on this fucking telescope?

Mirror manufacturer to NASA engineer: Oh! Who the fuck are you?

NASA engineer: I’m the guy who does his job. You must be the other guy.

[jaded_gerManic]

Yeah, the telescope needed 'glasses'! 🤣

[PeteTheGeek]

Common engineering result of "we don't need no expensive end-to-end testing".

[bovax]

I am old enough to remember this.

The reason HST was flawed was that NASA was NOT allowed to watch the mirror grinding from the company they contracted that mirror to because of "propriety knowledge" the company didn't want to "give away."

It's NASA... How they let that slip past their QC sensors and not tell this company "If we can't measure the mirror grinding so that it reflects our specifications, then you fail at the contract and it'll go to someone else" I don't know.

Thankfully HST WAS fixed and the rest is history.

That’s why the rescue of Hubble was created it’s not a disaster. It’s a masterpiece
