Hard to believe you don't get to the matter at hand until 3:40. This is a common mistake among pedagogues who have yet to grasp it's best to begin with at least a solid if brief overview of exactly what your title claims for the subject of the video. Talking about water vapor trapped within Webb's carbon fiber, instead, is simply ludicrous. Please, please improve.

A wonderful summary of the stupendous scientific achievement behind Webb!

"this video is getting long" BAH! I'd watch full hour long documentaries from you if you made them. Awesome work!

This is the most thorough and best coverage of JWST's instruments for the layman on YT so far. Thanks, Christian!

I've heard all the acronyms before but NEVER have had such a detailed explanation of what they do and how they actually work! Top notch information!

On one end the graphics look incredibly complex, yet on the other end Christian’s voice is so incredibly calm and informative it’s just so easy to make sense of the whole thing. Many thanks!

Those Launch Pad Astronomy videos are excellent, and they are getting better and better. This channel deserves at least one million subscribers.

The detail that you share with us about JWST is highly appreciated and the length of the video is not an issue. I expect JWST to blow our theories of the universe out of the water, even the ones we take most for granted. Keep up the great work!

Now THIS is the kind of science video I like to watch!

I'm so thankful for those capable of building the Webb (& typ) & of course those capable of explaining it's operation (you)! Keep learning & supporting continuing education! Which is what The JWST is all about!

Thank you! Finally someone who wants to nerd out on the instruments and not just talk about how it’s orbiting or how big the sun shield is.

can't believe it's almost been 2 months since webb launched, feels like yesterday! can't wait for the first proper images after calibration!

As a fan of all things space, this was a great educational video. i wish more people were as excited about WEBB as I am.

"if a picture is worth a thousand words, then spectra is worth a thousand pictures" somehow this felt really nerdy and yet really cool at the same time

The quality and educational value of this video is mind blowing. Also that low key humor is the cherry on the cake.

Thank you for this. Sometimes, looking at all the suffering caused nowadays by sheer human ignorance and greed, one comes to believe that idiocy is almost the standard human condition. However, thinking about people like Mike Menzel and all the amazing experts on the James Webb and Ariane team working to push the limits of science with sheer passion and humble intelligence makes me proud to share with them and all of us that same fundamental nature that turns all of our eyes to the sky on a clear night.

The ease with how you manage to explain very complex things so even I understand them is from beyond this planet. Thank you so much for your efforts sir!

This is arguably the best and most detailed Webb explainer video on YT. Really glad I found this channel, I'm so excited for the prospect of what Webb will unravel

This the most detailed and informative explanation of Webb than any other channel I've found. Thank you!

As a Canadian I am so proud the CSA could contribute the NIRISS module and the Fine Guidance Sensor to Webb. The ability to analyze exoplanet atmospheres in particular is incredible and will hopefully help find Earth 2.0 as well as a million other worlds out there…

I have watched a lot of videos on JWST ever since launch, and this was the first one that really put into perspective just how much more amazing JWST images will be than anything we have seen previously. You did a fantastic job at breaking this piece of seemingly alien tech down into something a layman can understand. Please do nerd out on the cryogenic cooling system next time, I was actually bummed you didn't go into it!! Also wanted to add that the visualization of the light bouncing around the mirrors was jaw-dropping. It was one of those "huh, humanity sure has come a long way." moments. I can't wait to see what kind of beauty and knowledge this telescope will bring us!

Terrific Video! There are dozens of Webb videos telling basically the same things. This is the first one I've seen which goes into a lot of detail (with fabulous graphics !) about the instruments themselves. Great work - Thankyou

Thank you very much for pulling this together; this is a really wonderful summary.

It must have been a packaging and optical path nightmare to get all these instruments working off the same primary light cone! I looked up JWST's focal ratio and found it was an extremely long f/20 (actually a bit shorter than Hubble's f/24 though), which certainly helps when you have to stuff this many different things in the light path without them obstructing each other. Thanks for the great video; tons of deep detail with clear explanations and imagery. I'm looking forward to future episodes.

I stopped watching JWST videos because they all say the same thing, but when I saw the title of your video, I knew I had to watch that one! You didn't deceive me! I had no idea how complex its instruments are, it's amazing! Best video I've watched about JWST ever, keep up the good work 👌

Utterly brilliant channel. Such a superb upload too, I don't think I'm ever going to stop being amazed at how astonishing the JWST is. The next few years are going to be super exciting!

Thank you again for another detailed explanatory video. The more I learn from the instruments on Webb the more l realize the technical know-how and building of all the components couldn't happen overnight.

I spent 20 years working on optical design, analysis, and test for JWST. The MIRI-MRS optical design is possibly the most complex and amazing optical designs I have ever seen. The MRS is a marvel of engineering within the marvel of engineering that JWST is.

The optical design of the spectrometer section (excluding the pre-optics) of the MRS was carried out on a train journey from Schiphol to Heidelberg. The UK contingent was joined by their Netherlands colleagues (purely by chance) and they had a few hours to kill and a carriage to themselves. What else were they going to do ?

Why so much zigzag, right? Someone from ESA answered me on Twitter that this is because of size restrictions for the instruments compartment. It needed to fit in the rocket's fairing and could not be folded like the shields or the mirror.

I’ve been waiting for someone to make an in depth vid about Webb’s instruments, thanks.

Thank you for an overall explanation of the technologi used inside JWST. It seems that there have been used some pretty clever designs and engineering to build this amazing telescope - much more than just the golden primary mirror and the sunshield, which are spectacular complex too. I like the AMI mode. It's so cool!

Awesome video! The perfect mix of technical & functional explanations 👌 And please feel free to nerd-out about the cooling system in a future video... it's an acoustic system if I recall correctly? I've seen a few videos about the basics of the system (which is ridiculously cool engineering... pardon the pun!) so I'd love to understand how it's applied on JWST, especially with the issues of vibration being so critical 🤓👍

An absolutely smashing presentation. What a relief someone has taken the trouble to do into much greater technical depth. I'm often asking JPL to do the same. Alas... This presentation, however, more than just wets the appetite. Thank you.

You make the best videos explaining the intricacies of JWST. Somehow I must have missed this one. What a jewel JWST is!

Fantastic job Chris! I'm amazed by how far the cutting edge technologies (shocked by the microshutters) already got as well as how clear you present these sophisticated systems. As a taxpayer, I'm totally convinced that this beautiful beast is well worth the $10B!

@asicdathens

NIRSpec and MIRI were manufactured and paid by ESA and the member states (The launch as well) FGS was funded and made by CSA. The $10B price tag is partly Northrop Grumman's machinations to squeeze as much money possible from a space project. Every day of delays while in US soil had a cost of $1M .

You are correct; each reflection is "imperfect" but it can be >99% reflective. Each surface figure imperfection also degrades the image quality, but again, we are talking about extremely fine quality mirrors so the final image is still diffraction limited!
