No:
>dead pixels arent a problem because we can just use the magic eraser in photoshop to invent datapoints
A hole in the mirror doesn't cause dead pixels. Optics doesn't work the way you think. Every part of the mirror contributes to every point in the image. A defect doesn't leave a hole in the image, it just decreases the effective collecting area.
If you have a reflecting telescope you can look through it while waving your hand in front of the primary mirror. You don't see your hand or a big hole.
Also note that JWST has fricking tons of dead pixels, just like every telescope using infrared detectors. Dithering during imaging moves the dead pixels around so you get a complete image.
Nope. Note how there is a huge fricking hole in the middle of the mirror for the secondary and aft optics. Doesn't stop the telescope working. It will make the point spread function slightly more complex and extended, but not at the level a human will notice.
HST's mirror was never touched during serving.
so what you are saying is the picture isn't real and none of it matters
thanks!
leave, chud
You don't use bad pixels, just like you don't use photoshop for data reduction.
If that were true, segmented mirrors wouldn't even be possible.
>If that were true, segmented mirrors wouldn't even be possible.
the tech which allows segments to be aligned better than quarter wave has been around for over a quarter of a century.
Why would you listen to a THOT that posts bikini videos?
Because our goddess Tibbies gave up physics.
it was never real. Practically every institution is a corruption now that embezzles money from the government into one country. Guess which country.
>nothing I don't like was ever real.
Namibia?
Zimbabwe?
Nauru?
Ireland no joke.
I didn't ask you.

I didn't ask you.
Whatever country it is, it definitely isn't Israel, because that would be antisemitic.
its all part of NASAs plan to lie that its destroyed, so they can use it in secret without having to give the public pretty pictures once a week.
>the telescope will also help NASA get a better understanding of just how many micrometeoroids there are in the deep space environment.
I think they're slowwly realizing what a deep clusterfrick they're in. Just 5 months into the mission and the mirrors are bent! On a telescope that can't be maintained!
I suspect nasa will under report news such as these in the future. As time goes they'll probably have a highly complex processing filter to correct all the dents, burns, scrapes that thing will develop over time. Maybe they should've put it in a glass hamster bubble like the one in jurassic world.
Nah, you can still focus with a damaged mirror, but the imaging quality obviously decreases. Assuming it's really only a small dent in one of the section mirrors, it should be negligible in the overall data aquistion. It would be much worse if such meteorites hit the spectrometers or the CCDs for example.

it's only a matter of time, it's over
That's fine if this is the only meteoroid strike on it. If this happens every couple of months, it's going to quickly become space junk itself. Both the size and frequency of strikes was predicted to be less than this.
>>the telescope will also help NASA get a better understanding of just how many micrometeoroids there are in the deep space environment.
lmao, that's premium quality cope, they should have put in orbit a dirty mattress and learn the same, instead of a billion dollar satellite
They'll get some AI to regularly pump out same looking galaxy pics as the real thing falls to bits and pieces.
DALL·E 2 to the rescue of NASA
>Mirror gets shot 5 times with a revolver

>Telescope still works fine five decades later.
All of the doomers are going to be disappointed when it continues operating just fine. IQfy doesn't understand optics apparent, a little scratch on a mirror does not stop it working.
And here is an set of images from TESS of debris from an impact in the instrument bay. Again, still working fine.
And if you think Hubble never suffered impacts because it had a tube then you're delusional. The debris environment is way, way worse in LEO. There is no way the back of it looks like this and the mirror just happened to never receive a hit. It's just that they don't have pupil imaging and so have no way to see impacts.
I think you'd agree that JWSP has more exposed parts AND unlike HST, you can't send astro-plumbers to fix any of it.
A little scratch on a mirror absolutely will make it impossible to accurately resolve objects billions of kilometres way
you have obviously never used a mirror telescope
ground based telescope can still function with low quality optics and th resulting fricked up psf, such as in your pic, because their imaging never gets anywhere near their dawes limit due to atmospheric interference which jwst is not hampered by. if jwst had similar damage then it would show in the psf.
Ground based telescopes still have to be polished to 1/10th lambda to get decent performance. JWST has a lower tolerance than most telescopes in terms of fractions of lambda but it's only diffraction limited at wavelengths longer than 2 microns. Whereas ground based telescopes are specced for visible.
No.
Cant we just send a space repair team to it or something?
How could they repair - in space - a mirror that took years to grind and polish? Even if they have a spare mirror somewhere, it would be fruitless to replace the damaged one, since it's clear those impacts will keep happening.
It's like changing a flat tire for a car that is driving on molten lava.
Best they could do is replace bad mirror segments and then put a shroud around the mirror to block out a lot of the impacts.
Won't happen though because nobody at NASA except the astronauts has the balls anymore.
>NASA
I'm sure they'll affirmatively act it right out of existence within a year.
Are you shitting me the mission basically just started how are the wheels this fricked up already, what chinese plastic shit did they send up there
that's the Curiosity's wheel, don't worry anon. Perseverance is doing okay so far
regolith on these planets without proper atmospheres is like rocks that are pulverized to powder and still have all the microscopic sharp edges. the moon is even worse.
they learned from that old rover
thats one of the older rovers
You aren't concerned that a multibillion dollar machine could be completely useless after 20 years of developing and manufacturing? You don't understand the value of time don't you?
>It's over isn't it?
It never even began fren
we aren't in trouble
>yet.
So when is it going to start taking cool pictures?
