Exactly what I thought, Martin

I've got my undergrad and masters in Physics, and currently work in a high tech laser company. Can confirm that academics love xkcd

You got a Masters in 4 years? Nice. Congrats!

@@Sinnbad21 I got an "integrated Master's". They're common in the UK - 4 years long. The first 3 years are a normal 3-year bachelor's. The 4th year is basically a condensed Master's degree. I got one qualification out of it, which is recognised as a Bachelor's + Master's.

@@scottrobinson4611 ah I see. That’s awesome man. The way it typically works here in America is 2 years per degree (roughly speaking) 2 years - Associates 4 years - bachelors 6 years - Masters 8 years - Ph.D/Doctorate But they do have accelerated plans like the one you took here as well. There’s plenty of exceptions to the timelines I gave but it’s generally the average timeline you see here

@@scottrobinson4611 If you don’t mind me asking, from what you remember in college, what lesson/s was the hardest in Astrophysics to learn or grasp?

@@Sinnbad21 I found some of the content in my "Extreme Astrophysics" module the hardest to learn. The module focused on high-energy phenomena - lots of stuff on AGN (active galactic nuclei), accretion disks, I think there was a bit about supernovae in there too. Specifically, I remember covering "Bremsstrahlung radiation" in a few lectures, and the information just wasn't settling in my brain. It took quite a lot of effort for me to get a half-decent grade in that class.

The ultimate tease

I learned about it in early 2000's so I know what you mean. Very exciting times we are in!

I remember watching the launch of Cassini in the late 90's... waited 7 years for it (and Huygens) to arrive... and followed it for 13 years until its mission ended. I grew strangely attached to it and the mission.

asdf Those Space Agencies are or do a little bit of science and the rest is corruption... and this is the reason: With 10 Billion Dollars I can build a Spacecraft at least 10 Thousand years in advance while NASA not even with 10 Trillion Dollars. Why is that ? Because of the factor cheating... humans like all alive organisms like cheating others each time they can... which means the procedures they use for spending they money should be different... because it is not possible to survive in the Universe by cheating... it is just too big and we are just too small. They already lost more than the entire money in the Planet. And this is the explanation. If you dont have 10 Thousand new technologies that is equal to 10 Thousand years or more lost on technological aspects. And that is what they are doing at the end at those Space Agencies plus companies: destroying the future... because they wont be able to build more than what they can steal. For example: not even after 900 Thousand years they will be able to have the needed equipment. Also because of the factor cheating individuals. They think they are doing wonders or that they have advanced or great technological achievements. But on Space Projects they are at the Stone Age... how do I know that ? Because even for the Mars projects they needed to steal the comments on KZfaq... before that they wanted to drop people on Mars.

Great! I went to see the space station in bits when it was called Leonardo.

No person will be able to see it now for quite a while.

I will become physically sick if something goes wrong with this telescope!

I agree 100%

Great idea. Although I don't think we should try again. Most astronomers are kinda quiet about this because of publicity reasons but I think its now generally considered to have been a bad project. When it works it will be amazing but from a risk to science and price to science perspective it was a failure. It is now generally believed that more medium scale projects more rapidly is a better path. Eventually there would be another telescope like this. But I suspect WFIRST would have much higher priority and even after that the concept would be split into a coronagraph focused telescope for looking at planets and a first light focused telescope. We will probably wait for the larger rockets (starship, ect) to create non folding versions before attempting a telescope this size again.

“Also” you should be honoring all the Mechanical Technicians who actually built this amazing hardware. We spent so many years of our lives building, testing and re-testing all of Webb’s deployments, systems & sub-systems. Technicians are actually the first to see where designs are flawed and need to be modified or redesigned. Working on Webb is definitely the pinnacle of my 35yr career in aerospace. Go NGC!

if james webb is successful it will definitely become a wonder in civilization games (just like hubble is), you mentioned golden age made me remember this lol

Well, Hubble has been running for 30 years and still can go another 10-15. The lifetime for this one is a meagre 5 years until the Helium runs out. I suspect this one will be a disappointment

@@luisbeck007 Oh man, you need to lay off the leaves.

they would probably build it very differently. i think there might now be larger rockets coming that would mean it could be less foldy... but yeah the main mirrors and stuff could presumably be made much more easily.. in fact i wonder how many spares they built of a lot of the elements.

Because it took so long to develop, a lot of electronics and software that went into JWST is outdated by todays standards simply due to the fact of what was available when it was designed, built, and tested. Not to mention other issues they had which work arounds had to be developed. Those would require design changes to avoid repeating. If it needed to be rebuilt, many things would need to be upgraded. So a lot of R&D would still need to be done to qualify it for space.

I think they would just proceed with LUVOIR

Northrop Grumman ate $5 billion before they even started building it, so at least $5 billion in R&D.

@@MyAvitech if it's technically outdated and a copy of it would be unfit for space as is...then how is the current model considered fit for space?

Calculus is a stumbling block for a lot of people, and law school is a noble field to go down!

Pisslam will never invent anything like that

The hinge did failed. They needed to reschedule the launch lately because of that.

@@S.... It was a holding clamp that failed. The hinges the OP is talking about are the ones that need to unfold at the final orbit point.

@@Pauly421 Oh, those also failed in the tests and were called "moderate concerns", one step higher than "acceptable level of risk but continue to be monitored". A couple years ago they said that nearly half of single point failure models involve the deployment of the sunshield.

@@S.... Was just referring to any and all components, and the anxiety of those who worked on it about their part of it. Would not want to be the one responsible for failure of the whole project, due to their component failing. I know they tested it extensively.

So many were skeptical of the myriad of in-flight assembly steps. Very grateful your team proved them wrong.

They are very brave people.

As well you should. Remember when they sent up the much simpler Hubble, then realized once it was in space that it would need glasses to see in focus? Luckily they could just send up some dudes to install corrective lenses. With this weird thing, no way.

@@carlodave9 Thank you so much for that

u are so optimistic. my guess is something goes wrong. JWST got too ambitious. A 33% bigger Hubble would have been great and a lot easier.

@@plasmaastronaut its going, and I believe it will succeed

@@Yarmox theres always something they didn't anticipate: the moon will get in the way as JWST travels to L2 and the scope will crash into the sea of tranquillity

I believe the ‘dish’ can pivot and move to focus on objects.

Don't worry about it. If anyone in the project had concerns about any of the procedures, we would've heard about it by now. Aerospace engineering is like aeronautics in the sense that everyone involved are pretty aware of risk assessments, potential solutions and why the current process is the best option considered so far. Plus they've had all those years detecting possible failures and refining everything, with the last delay caused by a shade deployment test incident. The scary thing in engineering is when someone tells you they never had any concerns about the project, then you have to worry... a lot!!!

@@RadeticDaniel Everyone is concerned and we heard it multiple times.

@@RadeticDaniel You're right in that they would have worked extensively to identify any possible issue and to minimise the risk, but in such a complex mission there's always a chance something has been missed and could go wrong. In aerospace engineering, sometimes it doesn't matter how much preparation you've done, it can be incredibly nerve-racking

@@matthowells6382 well, at least from the pilots side in aeronautics I know the mindset is "always alert, never anxious". If you start to slide from focused caution into restless concern, it's the signal to switch out with somebody else and make sure you don't compromise safety (or efficiency).

Very proud!

Station keeping fuel is one thing, with careful operation it may easily last twice as long. The real problem is the cryogenics to keep the instruments cool, those really can't be stretched longer.

They have 10 years from the point it reaches it’s destination, granted that it does so… to come up with a plan to refuel it.

I'm the same. I want this to succeed not just for the myriad talented and passion individuals who have spent so much of their lives on this, but also because of the dire situation humanity finds itself in with the pandemic. I feel like this succeeeding would be the icing on a cake that have been deprived of for so very long. So, no pressure or anything JWST - I love you and your creators efforts regardless of the outcome, but of course; fingers crossed.

That dust meant that the mirror polishing machines were just unreusable toxic waste after they finished.

I'll mind that in the future.

Beryllium windows are also used in X-ray machines and microwave ovens due to their transparency in those wavelengths

And its non sparking property.

It was designed before the ISS was a twinkle in NASA's eye.

Fun fact is that it will be just cooling for a couple of months and only than it could be turned on for those calibrations.

But it would be much more likely to blow up before it gets to orbit...

Except that there is no starship to fly it

Because you know more than NASA sure 🤣

I think that is far beyond our current robot capabilities

@@gyorficserka I think it depends on what the mission would call for. Say the shield didn't fully deploy and we knew for sure that we could get it unstuck with one simple operation, I gotta think they would give it a go. I mean, we're talking about a $10 billion project here, so if they could fix it for a fraction of that, then that could be worth it for them. Anyway, I looked and it turns out that JWST does have a "docking ring" on it, so I guess they must have some plans somewhere. I'd be interested to know what they are, even if nothing goes wrong.

@@ThisSteveGuy That's easy to answer. There are no such plans. The number of possible failure modes is just too large, and the percentage of them that would be fixable even with unlimited resources would be too small, to justify the development of such a solution. Its cost and complexity would quickly outrun that of the telescope itself, for something that everyone hopes would never even be used. Another problem is time. By the moment we press the launch button, this telescope comes with an expiration date, which is set by the amount of coolant and propellant on board. These will run out regardless of whether the telescope is used for science or not, and they will run out fast (JWST has about 10 years). So, if we found a problem and then started developing a solution, that would take years in itself. By the time we might fix it, too much of the mission would be over to make it worthwhile.

You are right about the docking ring though. That was a simple addition that makes a service mission by astronauts at least theoretically possible. Sadly we don't really have the rocket to send the astronauts there (NASA's SLS rocket suffers massive delays as well), but if JWST needs fixing then that extra motivation may do wonders. Who knows... Would NASA rush the development of a crewed spacecraft to fix a machine, and risk the lifes of astronauts in the process? I don't think so. In that sense, this possibility really is theoretical, and is there to silence those critics who may one day say "you could at least have put a docking ring on it". There's no way we'll ever use it, but it doesn't cost much.

@@renerpho I've read that the JWST also includes ports made for refilling everything while in space. I'm not saying that means a refueling mission is likely or anything, but I'm still curious about what plans exist. NASA tends to plan for every imaginable scenario, after all. And yeah, they would never consider flying people way out there, that would be insane. I'm only talking about doing these things remotely with a robotic arm or something.

I promise you that it would be, and it will be powerful enough to cause a lot of carnage.
