>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 clusterfuck 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.

All of the doomers are going to be disappointed when it continues operating just fine. /sci/ 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.

[Anonymous No.14562125]

>>14562115
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

[Anonymous No.14562244]

>>14562220
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 fucking 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.

>>14562226
Nope. Note how there is a huge fucking 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.

>>14562200
HST's mirror was never touched during serving.

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.

[Anonymous No.14562753]

>>14562115
ground based telescope can still function with low quality optics and th resulting fucked 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.

[Anonymous No.14562770]

>>14562753
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.

[Anonymous No.14562903]

>>14562828
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.

>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.

[Anonymous No.14562936]

>>14562903
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.
