When hubble did the deep field image, humanity had a "we know nothing" moment. I can't wait to see what moment this will bring. Its going to be totally worth the wait.
It's going to be absolutely incredible. What a wonderful time to be alive.
i heard that images from this telescope will be available just for scientists
@@zelez4ever we will get edited images in 5 or 10 years with a nice lollipop and forehead pat.
@@zelez4ever Not so. People spend years deeply engaged in such projects so it's only fair they get the first bite of the cherry when the results come in, but NASA are more and more ensuring that the public gets data as fast as possible as they realise it's all great PR. The mission to Pluto last years had the same protocols regarding the release of information to the public once the project scientists have had their first look and that worked fine.
What moment this will bring is we may see aliens waving at us from another galaxy. James Webb would stream it live here on TH-cam. I can't wait to see this.
Just remember, work on the Hubble started in the mid 70's.
Actually it was the late 1960s. The Large Space Telescope LST was originally going to be a 3 meter mirror. It was shrunk to 2.4 meters because the Shuttle was designed to launch Keyhole satellites. NASA wanted the Air Force's deep cash pockets and made the Shuttle just big enough to handle those spy satellites. NASA knew the Shuttle was a bloated monstrosity and wanted it no bigger than the Air Force needed. The LST was shrunk to fit the shuttle.
Also must think about the contributions of those talented scientists who have passed since.
Nice I should be around 35-40 if it goes the same
basically, many of the people waiting for this thing are now dead.
Back then technology was different. We’re far more advanced now so the fact that it started on the 60’s doesn’t matter
JWST: Just Wait Space Telescope
Ha ha ha ha 🤣
Wow nice trick
hahaha lol
Lol 😂🤣😂
I remember seeing an illustration of the James Web Telescope in a science book when I was little. I'm now nearly 33 ...
impossible, you were 20 25 years ago. You are therefore 45 yo now.
@@ThomasJr Nope. There was an illustration of it in a science book in the '90s.
Rome wasn’t built in a day ! Its soo close to launch now. It has been delivered to launch site !
That's quite old mate
@@yashmore5038 30 isn’t old
With this telescope means even sharper wallpapers!
lmao
Only if your screen supports near-infra-red display colors.
@@marvinkitfox3386 that is not how this works lol. The infrared image is displayed in light from the visible spectrum... obviously... otherwise we couldn’t see the image lol
@@MsIrrealis yes but we stil can't show all color of lights in the screens for example there's a pixel in certain image made Android phones to go in restart loop forever just because that pixel colour is still not supported by Android
where can I find great 4k space wallpapers?
I can't imagine the amount of stress involved in something like this, their is no copying this is all original and has to be 100% perfect or its just space junk.
not to mention the price of the thing, to get it to the orbit beyond the moon. makes launching satellite child's play
@@nickacelvn Its not in low earth orbit, its going to L2 or the second lagrange point, it is past the moon, servicing it would cost more than the telescope it self.
nickacelvn you sound dumb delete this
So here's the breakdown.
1. We have the schematics. So yes we can replace this. We already have parts that have been classified as outdated, but replacing them would be too much extra work. So if we did rebuild this, it'll be much faster to do.
2. If the launch sequence does have a problem, they can fix this. The satellite will take small pit stops before it starts it's L2 orbit. So if there is a problem, then they can fix this.
3. If the satellites mirrors or processors have a problem, then we have a solution too. You can use up the satellites last power to push it back towards the earth. This will be a very slow trip back, but once it returns to low orbit, we can fit this there.
9?
0:37 "scheduled launch date is in March 2021"
Me: found this video March 2021.. frantically looks for launch date
Hehe I also just found this video and James Webb is still on earth. Launch is now in October 31, 2021. We will see how that date will age :P. The funny thing is that Starship will probably be ready in couple of years and that thing can take way larger things to space than any rocket today. So no need for that complicated folding design...
I found this vidio on 1st of April 😂
It's pushed back to 31 Oct so the JWST will launch in Halloween
It's already may:)
@@randomizer4889 bro it’s almost June 😂😂
The rocket that sends this telescope into space better be 101% guaranteed to safely get it up there.
Intiger overflow: now the rocket only has a 1% chance to get up
@Chris B ok
That's why there's SpaceX
Kevin Detky
Yeah well as far as I know there’s only ONE James-Webb telescope. So this needs to be precise.
Eagerly waiting for the historic day. Hope everything go fine..
I'm going to be nervous when they launch this thing.
i really wish spacex falcon heavy was the lift vehichle sadly it is not
It's like leaving a chandelier ontop of your car and hoping it doesn't break.
Oh yeah. Nail biter
@@RealUlrichLeland only a billion times more expensive
I was getting nervous as hell just by watching this video lol :D
2 things are always a decade away. Nuclear Fusion electricity and the James Webb Space Telescope.
Fusion's been doing it for longer, though. And it will probably keep doing it after JWST launches in five years. Damn you fusion, stop playing hard to get!
mark my words, the day someone builds a working fusion reactor, humanity will be in a far safer ground than we are now.
3, Don't forget; the end of the world from man made climate change. COUGH-idiots.
@@alanwatts8239 Working fusion reactors has been built, the problem is that they consume more energy than they produce. Now the first net-producing fusion reactor is being built (ITER in France), but it is excruciatingly expensive, and it will yield only half a GigaWatt.
@@alanwatts8239 I drove next to ITER (Cadarache in France) a few times and it's like a movie, the army is patrolling everywhere and the site is very protected
I have a friend who work here as an engineer
As sharefactor said, the problem is that they consume more energy than they produce and we're still not able to maintain a plasma for a long time
The first real test plasma will start in 2025
This dude sounds like he’s on the verge of laughing constantly
Lmao
Josh lol
The quality of this comment should reward you and your next 7 generations
Right?
:D:D
My Dad and I followed the progress of the JWST, and discussed the implications of its findings, for nearly 20 years. He passed away in 2018.
I’ll be watching the launch with an eye on the rocket and my mind on my Dad.
:(. He's watching it with you
@@massivemagoo no he's now, that's why it's sad....
Legit hyped for the telescope. The launch is going to be like a Superbowl times ten for me. Will watch it LIVE.
oh boy, that would be awesome
What if a meteorite hit it?
@@Marox.. Word's most expensive firework.
@@Marox.. | could happen. would be super unlucky, i guess
When it is finally working I want more telescopes to be made on the same principles. One for visible light, one for UV, one for X rays and one for gamma rays.
I guess 2 more for radiowaves and microwaves if they will benefit from it.
I like how the mirrors in real life are even more perfectly reflective than the mirrors in the illustrations
Are you saying that in the same sense as seeing everything in real life at a higher resolution than possible with any photo/video?
I hope there's a secret japanese double being built just in case like in the movie "Contact"
Yeah don't worry. I got it covered.
@@rikijenkins6729 Thanks 👍!
Everytime I think about the James Webb telescope, that thought pops into my head. The the amount of time and money spent on this telescope crazy. I hope everything goes off without a hitch, especially the launch. 🤞her fingers.
5 years later: Why is the James Webb Space Telescope taking so long?
Job security is job 1.
Imagine then it fails to launch and explodes!
It's now 14 years it was supposed to go up in 07
@@scottschell6045 No... 5 years after this video.
We might be getting it in November, that's 5 months from now... Fingers crossed.
Thank you engineers and scientists for all that you do for humankind and beyond.
Merchant Princess they’ve done nothing. We haven’t been to the moon ever. If we did we would have went at least once in the last 60 years
Unknown nothing good for mankind. Can’t solve disease, can’t solve global warming, nothing major in innovation happens anymore. We are stuck in our ways. If we really went to the moon by now we’d have missions going and using its resources
@@killap3nguin Lmao let's just ignore the exponential change in accessibility and knowledge humans have gained within the past few centuries. Remember the last time your common cold symptoms were a possible sign of sure death? Yeah me neither. Be thankful.
Colby Boucher within the last 50 years lol no. We’ve made minimal gains in medicine and space.
@@killap3nguin says the guy using his smartphone with gps to communicate 😂😂😂
Wow, the engineering and science behind this telescope blow my mind.
Ought to blow your mind they had no idea on how to build it when they proposed it. Said they'd figure it out as they went along. Guaranteed cost overrun by over 1000%, one billion to ten billion. They knew they'd be milking this cow for decades.
@@MountainFisher i can smell the jealousy trought the screen..
Not everyone cares about how much money someone else is making while furthering our understanding of the universe.
But!!! Moooom!!! The evil elite is stealing my money !!!!!* moooom....
@@megsinzoa7424 Jealous? No pissed that they knew they could not build the JWST for one billion, but they proposed it like they could, after all it's just one satellite. I worked in aerospace for most of my career and saw the milking of the taxpayer on cost overruns on just about every new program, but at least in the 70s and 80s you had to produce something that works. Now it's finished, but they're going to "test" it many times for launch in two years, be surprised if it does launch, but for over $10 billion heads should have rolled and competent people should have replaced these toad suckers. That is what used to happen if they didn't just drop it.
@@megsinzoa7424 Oh and instead of exploring the universe I'll probably die before JWST is finally ready to work. If the people who proposed it had talked to an engineer they would have been told that there is no way it could be built on time or for the proposed cost. Ten billion could have done a lot towards exploring space if the money had been given to responsible engineers. 2007 to now 2021 is a rip off of true exploration.
@@MountainFisher I'm not even remotely in the field, so I could be (very) wrong. But I have the impression that many smaller projects could not equal the eventual results from the JWST project. So I'm glad that this project is happening, even if there's a lot of money stealing going on. Similar with the ITER test reactor - I've heard similar complaints, but I still believe that it's better to have ITER built.
Thanks for sharing this other side of the issue, that you see; it's easy to be only impressed with such projects when you look from afar. But it's usually more complicated.
It's nice to watch this video now in the future and see what an amazing success JWST has been just within few months of operating. The wait was all worth it!
It is so fun to come back and watch this video. You do an outstanding job in your editing. Today's date is 1/13/22 and the JWT has successfully deployed to date meeting many milestones but still holding my breath. Excitement in the community of star watchers is palpable and I'm enjoying every second. Thanks for doing an outstanding job to inform along this journey. Much appreciated.
welp it's safe to say that this telescope is going to clap hubble's cheeks
lmao
If it ever gets there
@Oh yeah yeah It's a good thing it has 18 of them.
I'm fucking dyyyying laughing, that was hysterical.
Hahahaha. Like "hold my beer" meme.
If this telescope fails the collective face palming may cause a seismic wave that shifts the Earths orbit.
then better not launch this with spaceX xD
@@Knightfire66 Space X have a pretty good track record for deployment and take off....Their booster landings aren't always perfect is all. As far as getting shit in orbit goes....They're pretty top notch.
@@Knightfire66 why not though?
@@somethingsomethingname25 oh yeah yeah
I appreciate your concern, But do not worry. (that will be tested too...)
imagine: this means tech from the 2000s is launched in 2020s
imagine if we had the 2020 tech right now
then the 2020 tech wouldnt be launched till 2040 xD
They will make a rocket one day that can fly to the JWST orbit. To upgrade it. Scotty from Star Trek said so.... 🤣
Actually they started designing the tech in the 2000s, it's only being finished now as cutting edge 2020s technology, like the spectroscopy device shown in the video that has never been seen before. Most of our 2020s tech also started being designed in the 2010s and earlier, because it takes so many years to bring new devices to market even outside of aerospace. It always amazed me in the past when I bought an Intel CPU and on it there's a copyright year that's 5-6 years before the original release date was. Imagine working for these places and getting to see the prototypes and test samples - they're literally future technology, what will become the latest and greatest to the general public years from now.
I suppose it would be more accurate to say here we are stuck with 2020s technology when internally many of these R&D companies are using 2030s technology already...
Not really how it works. All these systems and mirrors etc are techniques developed over more than a decade, and it's finished now. It's launching with pretty cutting edge tech.
The predecessor next telescope after web is already way farther ahead and then web and it's in a desert in Chile they say it'll make web look like a little mini they'll probably be done with it before web is guarantee if Congress tells them they ain't getting another dime that thing will be up tomorrow
Astrum sounds like he's constantly happy about what he's talking about. I like that.
His name is Alex McAllum, something like that
And I thought the Mars Exploration Rovers had a scary deployment sequence...
James Webb Telescope should be capable of detecting light from stars that was emitted around the time they first started building it.
Too funny...
hahaha
For anyone curious, the new launch date for the JWST is October 31, 2021. Hopefully we will actually see it launched this year!
you can only hope.
Closest thing I've had to a nerd-gasm was watching this marvel of engineering.
Because apparently there aren’t supposed to be leftover bits with the IKEA parts they ordered.
@Ungregistered User I have!
I can highly recommend it.
Better pack an extra wrench just to be sure
ja565hr IMO one major reason for that is because the furniture from home and the decor don't match with the ikea piece.
Anton Boludo - LOL! The best part of glue together, screw together, alleged furniture is that it is super easy to break up and toss in the dumpster. 🤣
@Ari Naughty!!! You aren't supposed to think like that!!! 😎
10:53 whoa wait,it's fully built now but they're just going to test it for two more years before launch? hats off to the team of perfectionists, I hope it all goes well
@Ben Jackbag Mank Go on, twitter warrior. Go and build a multi billion USD telescope. Place it at an unreachable, but needed, distance for humans which makes it unserviceable.
Everything goes to plan, until something doesnt. Realize you cant service it... you should have tested WAY MORE... trash it. No scientific knowledge has been gained, years of time have been wasted, and on top of all that you have to fight the possible shutdown of your space program after wasting 10 billion USD.
People like you just search for an excuse as to why they are still breathing.
@Ben Jackbag Mank have you heard of the dunning kruger effect? i bet that you would have done much better than them hahahahahaha
@Ben Jackbag Mank ok, what about the logistical difficulties in making a modular telescope? you are aware that this telescope is going to be in L2 and not in LEO so you're going to need a ariane rocket for each of the launches considering that the arianes are the only avaiable rockets at the moment that are capable of sending payload into L2, but guess what, the entire james webb telescope is already going to be sent by a single ariane rocket.
Ben Jackbag Mank what's the name of the engine? is it publicly accessible? i'm genuinely interested if it is one of the most accurate.
@Ben Jackbag Mank How would you taxi it? (honest question, just learning)
I literally get goosebumps in expectation for the images this machine will be sending us in only a few weeks!
After reaching L2 JWST will take another 5 months or so to start working because of calibration, instrument cooling and stuff. Correct me if I'm wrong.
An unfinished game will eventually be good... a rushed game will forever be bad.
👎
Terrible example, look at no mans sky it was rushed out and it’s reception was terrible and it was patched for years to the point of being well received. A lot of games as a service are rushed out with the plan to patch out the issues
@@brandanmurray193 wasn't it in development for like 10 years
midnightfeeder no, not no mans sky it’s development cycle was 3 years.
Half Life 3?
I just hope the launch goes well.
Talk about nerve-wracking.
Me anxious af
Launch may not be the most difficult part. Deployment will be.
They will use SPACEX
They better have a good payload ejection system if the rocket explodes.
seing them flip that mirror upside down gave me soo much anxiety
Wtf no
Jucho for some people
I swear
did you notice the hair line crack on the lower panel
Lest we forget how long it took to get Hubble launched and functioning. At first the images that came back were distorted, but then they were able to correct for a minute warp in the mirror by computer. Then they sent a team up to service the telescope, on at least one occasion. I should wonder if there would be an advantage to launching a telescope into interstellar space. The edge of the solar system is very far away - 9 billion kilometers. But space there is colder and the sun wouldn't be a problem, and there are also fewer atoms of gas in interstellar space which would improve the resolution of the telescope. It would be an incredible vantage point from which to explore the Keiber belt and the Ort cloud beyond. These are regions of space we know so little about. But it would be science for a future generation, because it takes 40 years to get there.
I actually won a NASA competition about the James Webb Space Telescope a couple of years ago and got to meet some of the designers of the telescope. It was a really cool experience!
I'm beyond hopeful for this project and I don't care how long it takes to get it right!
Outside of manned spaceflight, this is the most exiting thing in space exploration! Hope everything goes right when this gets in to space, because the discoveries the James Webb will make will be incredible!
Its cool yeah, but have you seen the TESS space telescope? Its method of operation is just mad and it will study an area 400 time larger than Kepler did for exoplanets. Its going to be a prime source of targets for the James Webb, though at this rate its mission will be over before JWST even gets off the ground.
Manned space travel is a waste of time. Instrumentation and probes makes sense
@ungratefulmetalpansy great comment. Spot on
If it gets to space
When we build a base on the Moon, then we can build the biggest telescope ever. Since there is no atmosphere on the Moon, it is the perfect location for building a ground telescope.
@Nirek Setty they’re making a moon base though?
@Nirek Setty They are but I highly doubt it will have a telescope like this within our lifespans.
I still hope they will prove me wrong though.
@Nirek Setty they are, in 2024

Replace Arecibo with a telescope in a crater in the moon
@Nirek Setty artemis has entered the chat
I truly hope everything is working 100% for this amazing engineering feat by Oct. 31 launch date and that everything else is just perfect on this day. Other than getting people into space consistently and safely, this is one of the most exciting things I can think of in my lifetime.
Dec. 22, now - they also just started the fueling process.
@@jeffbenton6183 Christmas now
im from future and this telescope is in space , floating
I am from the future and yes, it’s doing quite well. Completely deployed and closing in on its position at l2
I really hope everything goes according to the plans, we’ve been waiting a lot, but I know it will be all worth it! It shall be amazing.
if they spent this money on the poor there would be no poverty
@@arthurdonehower6115 Sure but this is an actual worthwhile project for the species, the money is fine to go to this, its the money owned by the billionaires than should be used to help the poor.
luckily you have lots of other things in life to wait for and to enjoy. If this was the only thing, it would be hard. But you get to look forward to a coffee every morning and you get it 2 minutes later. So life has a way of relaxing us
josh exactly!! I really love when my taxes contribute to space exploration
Scares me to death this thing, I have such high hopes riding on it.
Well, don't fall off! /s
yeah its such a strange feeling, on one hand i cant wait for it to launch but the risk of the launch is so great i dont even want to think about.
Rocket launches nowdays are 95 percent succesful. Back in the old era it was alot less so dont worry
ive been on the edge of my seat for 10 years with this project
@Vulcan Logix ______ ???
Absolutely incredible video man. Keep it up! You definitely deserve this like and sub. 😁
Very beautifully narrated. From the narration itself, I 'feel' that I understand everything .
I can't wait to see the first images taken with this in 50 years while I lie on my death bed.

Mind-boggling technology at work. Best of luck for this super advancement in technology.
I loove this channel! Thank you!!
I hope they've built a spare one. All it would take is a rocket malfunction to turn it into the worlds most expensive firework.
Well ,you're right .So maybe they should wait a bit. This year isn't look very lucky for anyone of us. Just in case..
Insurance for launches is super expensive, but worth it.
This is EXACTLY what I'm waiting on!

Bingo!
I mean that's not it at all. If you sneeze and rip this multi billion dollar telescope you will never step foot in a NASA facility again.
@@donbowerIt's not a serious hypothesis. But one multi-year delay was because there was a rip. I am a corporate project manager so I understand challenges. But as a fan, it's frustrating from the outside looking in.

Got so many moving parts it can be considered the first man-made Transformer.
That's what I call it
The should use 4 "Stretch-arm Strong" dolls to stretch the membrane...and a couple Gumby insulators...and some pull cords from some talking GI Joes with kung fu grip. That would have saved a billion dollars right there!
Great source of information. Excellent presentation! Thank you.
Such a beautiful technological work - I can't wait for the images to start flowing in!
Very informative Thanks
Thanks for the more detailed explanation, it was nice to get the specifics of how they made some parts and what it is that's holding up the launch.
nice job! You managed to get me totally jazzed about something I knew almost nothing of before this video.
sadly launch delays are a fact of reality .... no one ever figures out "we can launch much sooner" (without being gently led away... never to return)
Brilliant design and engineering... Bravo and Good Luck...
You can literally hear the narrator smiling during the whole video
You always sound as if you're smiling! That's so nice :)
Oh yeah totally! I always think of astrum, as a just happy to be Living person!
I just love it!
Matthias what a clever comment. It’s true, he sound happy and smiling,
I always thought this too, in fact I commented this on one of his videos before, I thought I was the only one!
I've always thought the same as well. You can literally hear this guy's smile.
I on the other side find it creepy AF.
Hubble : I’m ded already.
JWST : I’m still not born yet.
Durex: We proud of our product
Kepler: My reaction wheels don't work
I think Hubble will stay because we need a telescope near earth plus Hubble can do things that the James web can't do.
Ahahaha
*hubble will never die*
Two years ago it was uploaded. The time has finally come . Who are excited
I absolutely love this channel
its amazing to think that one side has 100 deg Celsius after few centimeters the temperature is -220 deg Celsius
I still get fascinated by how one side of my door is a cozy 75F while the other side is -12F in winter.
I see you on the Dark Side of the moon....
Temperature is just movement of particles or electromagnetic waves.
In a vacuum you have no particles to transmit that "heat" so it is not that amazing.
Beryllium is also super toxic, so it makes manufacturing with it very difficult and complicated. Lots of safety precautions and such.
carcinogenic af.
l u n g c a n c e r is most certainly the case when inhaling beryllium dust.
yeah, the engineers can get skin diseases that lead to disability or death if they're exposed to it for too long so i suppose that's also why it would take them awhile for it to get ready
Just watched a science vid where they said "And we will know much more when the JWST is launched in 2018." The vid was from 2014.
Nice video thanks
This video made me smile. This is the kind of science divulgation I crave for
Being an aerospace biologist/engineer and having actually worked in the "shop" building things I figure the engineers planned the JWST without knowing how to build it. So they had to figure out how to make parts of it as they went along, one reason they took so long. There are others too.
I remember waiting for it since I was a teenager. I am even more excited now.
Everything about this is so incredibly cool
Wow! Absolutely amazing!
If one person makes the most simple mistake it will be the biggest and most expensive hunk of junk in space . So please do it right
I worked for NASA in the seventies. In big letters outside the factory there was a sign:
DRIVE = Do It Right Initially for Value and Effectiveness
i do not want you to worry but this launch is controlled by demacrats in congress.
Exciting stuff!
Just can't wait any longer hope everything goes well keeping my fingers crossed
can't wait to see the pictures this thing takes
then you will not see lt

@@arthurdonehower6115 the true hype it is if it can find planet nine and what it can discover in alpha centauri system 😊
Right. In...infrared. You better get your infrared to visible light glasses now :D
In 2007 I thought 1080p was leading edge. I hope they upgrade the sensor before launching
You know they will, they're bound to.
The point is that they have made custom camera sensors that can focus/track 100 objects at the same time, with no noise, so its literally 100 of the best possible 1080p camera's packed into one. The amount of money these sensors have cost to be developed means they're not gonna go back and rebuild the whole thing because you can buy a 4k TV these days, those resolutions (highly complex space camera vs consumer gadgets/tv's) couldn't be more disconnected facts. Not to mention the fact that they can point several lenses to the same target with ever so tiny offsets to effectively increase the resolution.
Hubble space telescope does this too (combining low res pictures at small offsets into one high res pic) but for the Hubble telescope they do it by moving the whole telescope by microscopic amounts, the camera sensor is low res but it shoots like 400 pictures at slight angles that they then use to create a highly detailed '1500 megapixel' image here on earth, this James Webb telescope can bscly do the same but doesn't have to move around for it, instead those 100 internal micro lenses move.
Long story short dont worry about it, the fact its called a 1080p sensor doesnt mean it will give us 1080p pictures, while Google gives me all sorts of nonsense results on the resolution of the Hubble telescope (as in, the actual sensor's resolution) i bet you its below 1080p, remember that thing was launched in 1990, 17 years difference (in hardware development) with original planned James Webb launch date, James Webb is going to create higher quality picture's, theres bscly no question about that, and they really dont need to update the sensor at all even if launch still takes another 10 years of delay. Again, this is not comparable to your standard consumer camera sensor.
@@suicidalbanananana I would think that since resolution is one of the most important aspects about space photography then it would be great luck to be able to upgrade any photography equipment by a factor of 4 or 8 while it is still here on planet Earth. It would be irresponsible not to. Your argument about cost is valid, but looking ahead there is absolutely no way of spending that money on an upgrade once its launched and this upgrade is one that will even be overshadowed by another once this thing is gone. The idea is to put the best technology in it while they can because once its gone all thats left are wishes and regrets.
Thanks, Alex! 🛰️
Thank you brother
After waiting and watching for years I have a terrible feeling about this. So many things can go wrong.
Have faith in the Ariane V. Have faith in the JWST engineers. We are getting ourselves a new Hubble, and that's final.
That could be said for everything we've ever done involving space. The degree of accuracy needed to do even half of what NASA has accomplished is astounding, yet they've done great things. Have faith in them.
I remember in 2016 seeing "James Webb telescope finished by early 2018".. 2017 came nothing changed, 2018 came nothing changed and now it's almost 2020.
it is 2020 now. I'll tell ya when it's up
I cant wait to see the pictures
This is an excellent presentation. It would be interesting to find out how systems designed, built and tested at room temperature can possibly be expected to operate at temperatures around -220C.
They can only opperate at such low temperatures because hotter temperatures would interfere with the extremely sensitive infared detection systems. Thus they where tested at (or near) such low temperatures to insure structural stability and accuracy of the instruments.
