🔴 Webb mirrors are aligned! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-E-pNS5mDExQ.html

@esecallum Год назад

1/2 wits at NASA dragging out deployment while WEBB is being bombarded by rocks.they could have taken 20 million pictures but the morons are just dragging it out...THEY HAVE LOST THE CHANCE TO TAKE any pictures while mirrors were intact. they should be fired.

@ezekielbrockmann114 Год назад

Please explain to me how this is an "okay thing." It's only been open for a couple of months, why can we not extrapolate this to a constant degradation? It seems like a huge design flaw. Hubble's mirrors are encased.

I was real worried about Webb until you mentioned the mirror with bullet holes only losing 1% of its capacity.

@TheActionBastard Год назад

right? "oh. bullets dont stop it? well then... not so much an issue as I thought..."

@N73B60 Год назад

Actually less than 1%. 107 inches to 106 inches it's about -0,93%

@airtightbox Год назад

Safelite can patch up that while you are on your lunch break.

@georgevantuyl5837 Год назад

Unless that 1% is the exact point that you are observing. So there have been 5 total impacts since JWST has been in place and operational. Or a better way of linking at it. The JWST is averaging one impact a month, for now. I see the JWST as being positioned in a shooting gallery. I personally do not see the JWST as viable after two years. I am being realistic not hopeful. In a year at this rate the JWST will see at a minimum 12 impacts. I do not believe the JWST was designed with this high of an impact rate.

The Hubble Space Telescope has a two inch hole drilled through its main mirror. During the mirror's manufacture a tiny imperfection in the glass was discovered that could have started a crack that could have eventually spread across the entire mirror surface. Drilling the hole eliminated the imperfection so that it couldn't develop into a crack. The light gathering ability of the telescope was reduced somewhat but Hubble had sufficient extra capability designed in and has performed extraordinarily well for 30 years.

I've noticed the same thing. One report said that the main mirror was hit by a "space rock" that "smashed" into it. Another report showed a rifle bullet being shot through the mirror.

The debris is smaller than a grain of sand which still left a permanent damage. Now Imagine other micrometeorites/debris that will hit JWST in the span of its lifetime. And it will withstand many of them. The engineering of JWST is remarkable.

A disgruntled employee/astronomer in the USA in the 50’s or ages ago shot his rifle into the primary mirror of a pretty large telescope at an observatory MANY TIMES. the mirror had chunks taken out of it. So the plans was swept up and the telescope is still used today and it’s perfectly ok.

So if a mirror segment gets off-pointed in order to remove its contribution, it's still going to be pointed at SOMETHING. Would they continually re-point it so that for every target, that mirror segment points toward something dark? Or would they just defocus it?

As a geologist, I consider "sand" as particles between 62.5microns to 2mm (0.0025in to 0.079in). If one was to assume spheres of density 2.5g/cm3, and only vary the particle size while keeping the velocity constant (for the sake of a "back of the envelope" experiment), it's a pretty big range of kinetic energy.

If the particle hit with high speed, the fact if dust accumulates or disperses at L2 is pretty unimportant to the particular case, right? It had to have come from afar and probably did not get disturbed much by gravity around L2 would be my intuition.

This meteoroid is a statistical outlier. We've had spacecraft at Lagrange points for decades, including one with an unprotected mirror (Herschel), so we have a decent basis for statistical models. What we don't have is a complete map of all meteoroids down to sub-mm sizes, so statistical modelling is the best method we have for predicting impact frequency.

@@h.dejong2531 I appreciate the work that has gone into trying to understand and mitigate the risk. When most of what we can see in the universe is either very close to us and big or far away and self illuminated, statistical studies don't give me a ton of faith in what the future may hold. I'm very excited to see what is discovered using this new tool! I hope it has a full service life! On a side note, I always wonder when they talk about dark matter, how many dark "solar" systems there are where the would be star never gained enough mass to self illuminate. It would be funny if there were many more dark systems than illuminated ones, but we just can't see them.
