Webb Mirror Coating B-roll Footage

[@jerrycurtis9283]

In this video, I was privileged to be the Supplier inspector that was charged with watching every movement of each mirror and every operation on it to make sure that all safety procedures were read and then followed. That was my reflection in the mirror when it was flipped after coating to face the wall. I'm sure the NASA photographer was surprised to catch me in the shot.

That mirror is part of a $10 billion dollar project, I would say it's worth a couple million for sure and not just cause it's plated with a little bit of gold. I'd be having a heart attack playing with something that valuable, it almost makes sense why they go so slow and are so precise.

[@JakonHilfars]

Being someone that's used to work in mirror and anti reflective coating for almost 6 years. Knowing how absolutely important it is to make sure that your medium (your material to be mirrored or coated) has to be absolutely spotless to avoid having voids on the mirror. Also the cleanliness of the machine itself can cause issues. You're dealing with nanometers of thickness one of the layers I worked with was only .53 of a nanometer. I can appreciate the amount of work that this team did because I know how meticulous you have to be to create such flawless coatings. And just the amount of coating knowledge needed to operate such a machine.

[@EleanorPeterson]

Just one question about the otherwise first-class 'clean-room' hygiene precautions: why are people's eyebrows and eyelashes not covered? Anyone with a DSLR will know how annoying it is to see a bit of broken-off eyelash hair appear in the viewfinder. It happens... Humans shed 'stuff' all the time, so I thought these peeps would be wearing (at least) swimming goggles or clear shields over their faces. (Disclosure: I used to make very amateur-level telescope optics for myself and my friends - mirrors up to 18" and objectives up to 6" - and always had a hard time keeping things clean.)

[@mm-qd1ho]

People scrub themselves for 15 minutes before putting on the suits and masks. In addition, the room is pressurized and the air is filtered. They need to be able to see the mirror surface clearly. I think anything over their eyes would interfere with that. I don't know what class this cleanroom is, but in some Class 1 cleanrooms, all the air in the room can be exchanged in less than 10 seconds. This room is probably too big for that, but my guess is that there is enough controlled airflow to prevent anything from landing on the mirror's surface while it is in the room. I think that's what the majority of the background noise is.

[@pokemoncrusher1246]

@@UniversalStandard in L2 there is less space dust, the sunshield will also help reduce it and as a matter of fact, dust does not reduce a telescopes effectiveness significantly with such a large aperture, these mirrors are BIG. It would take time well past the mission life to cloudy the mirrors so much to where its useless. Again even if one of the mirrors is crackded for example, it wouldent make the mission useless, just degrade the aperture. Still a massive improvmenet over hubble for atleast a few years.

[@Doctor_Yuri]

Using goggles is more of a hinderance than not, so its not part of protocol. From someone who works in a clean room with flight hardware. This is handling. After all things are done, they are meticulously cleaned a final time anyways.

I find it a bit strange they are cleaning the mirrors by hand. :) There's a lot of stuff flying around in space. What happens if one of these 18 mirror segments get hit by some smaller object? Can they still operate and deliver?

[@guylavoie1342]

Well, "lot of stuff" is a relative term in an area 1,500,000 km from earth. It's always possible that a micrometorite could hit a mirror, and create a known bad spot that could then be partially be compensated for by moving the telescope slightly during the observation of a distant object.

[@whitelotus_zero]

My thought exactly, I’m sure there must be more precise automated process for cleaning, but perhaps machinery becomes too complex and / or manual is ”good enough”

[@David-hm9ic]

Sometimes manual is better than an automated process. The beginning of the video shows the technician removing dust and other airborne garbage from the surface prior to coating. The footage in UV light is them looking for any missed specks. The mirror surfaces are delicate but not as fragile as a dandelion.

[@TicTac-g7m]

Well, something tells me that they knew exactly what they should and should not do.

[@Doctor_Yuri]

@@whitelotus_zero Automating it would be much more dangerous. Having a cleaning "robot" or arm, or clean wipe lathe or something inside the Clean Room would be a hassle. Worst case scenario with a machine is that it crashes into the mirror like in a CNC. Worst case for a person wiping it is that they smudge it or something (just clean it again)

How surreal is it to those people that worked on each mirror, realizing that they were the only beings that mirror will see along with whatever it sees in space.

[@ezramatan5233]

I think type of process they're using is sputtering. Basically you create a vacuum chamber and use plasma or argon plasma to strip of atoms of a metal (called a target) which binds to whatever it lands on, in this case the mirror.

[@henryD9363]

They're coating it with a very very thin film of gold. This is because it's an infrared, heat, detector and gold is the most highly reflective material there is for infrared light. Nothing better. As an added bonus, gold does not corrode or tarnish while it's here on earth In the atmosphere. Both silver and aluminum slowly tarnish. So gold is a much better reflector and is chemically stable. I read that the entire amount of gold on all of the mirrors is less than 1 lb.

[@AfricanLionBat]

Did they have to build all of the equipment to build the telescope too? Did those stands and chamber have a purpose before Webb?

[@anullhandle]

Most of the stuff would be specific to the project. Many telescopes have their own vacuum chamber on site for yearly stripping and deposition of a new reflective layer. In principle it's just a vacuum chamber with tungsten boats with small pellets of pure aluminum or in this case gold in them. They are electrically heated and the metal boils off and condenses on surfaces in the chamber. The mirrors need to be super clean before they are coated but people do it in their garage for homemade telescope mirrors. The casting shaping and polishing of the blank is the time consuming precision work.

[@AfricanLionBat]
