Strange priorities? Defending yourself from people wanting to kill you, take your freedom, and take your property is *vastly more important* than looking at a telescope, no matter how you imagine it. And, defending yourself is a *necessary prerequisite* to indulging yourself on space telescopes. I am very impressed and glad we built this telescope and will learn the things we will learn, but you *must first live in a safe and secure civilization* before you can execute such a mission.

The JWST cryo cooling system is just something else entirely. I work as an engineer on land vehicle cooling systems, and the thing about cooling systems is you don't realise how little you understand about the science behind active heat transfer systems until you actually start designing them. The designers would have had to simulate and account for every single joule of thermal energy throughout the entire telescope, and then design such a cutting edge active cooling system with moving parts that can last for decades of non-stop operation with no servicing and with no allowances for failure. How many times the engineers would have woken up at night in a cold sweat! I'm not even one bit surprised that it cost $150 million to design.

@rljpdx
@rljpdx 2 роки тому
not only that, but i noticed passive analog cooling is ultimately being used to vent/radiate away the heat. what i mean by this is that it looked like they were using simple heat transferable metal (probably copper) to simply radiate the heat away from components and guide it where it's needed (the heat radiation). it's amazing something so technological uses one of the first ever but most used cooling methods devised. i'm not an expert on thermodynamics and my engineering skills are computer related, but it's all simply fascinating. maybe you could tell us more or correct me if my description is sketchy.
@jasonyoung1622
@jasonyoung1622 2 роки тому
@@rljpdx There's simply no other sink available to deposit excess heat into! You can actively transport heat about the system all you want, but in the end, the entire system's heat sink must be external to the system, and accessible by some combination of conduction, convection, and radiation. In this case, the sink can only be external space, and that is only accessible through radiation. On top of that, the act of transporting heat against the direction where it wants to go in itself requires energy. So really you're trying to reject both the energy of transporting the heat along with the redirected heat itself. Since the temperature difference of the gas at either end of the pulse tube is relatively constant, the theoretical minimum temperature (with no parasitics) of the cold end is the temperature of the hot heat exchanger (HHX) minus the achievable difference in gas temperature at either end of the pulse tube. Any steady state heat load present at the cold end increases that minimum temperature because the cold gas in the pulse tube has to remove that heat load from the cold end through the cold heat exchanger (CHX), and so the gas must be colder. The heat of operating the pressure wave generator is generally rejected into the HHX, or an additional supplementary heat exchanger (aftercooler) placed earlier in the system, but can diffuse into the pulse tube gas, or present a heat load to the HHX and raise its temperature. Additional parasitic type effects basically just include all the conduction, convection, and radiation modes between parts of the system at different temperatures. For additional information, Ray Radebaugh is an authoritative figure on crycoolers and has written comprehensive reviews of the state of the art. He has also taught a short course at the yearly International Cryocooler Conference, though I'm not sure if that sort of thing is going on this upcoming year.

​@@sadyaneem Occam's razor solves your theory. Occam's razor states that the theory that requires the fewest number of assumptions is typically the one that's right. As of right now, the evidence suggests that we are living in the most technologically advanced segment of human history. Does this mean that it's a guaranteed fact? No. But, that conclusion is the one that requires the fewest assumptions and therefore, is most likely to be correct. For example, is it possible that you simply popped into existence last Friday with all of your knowledge and memories preplaced in your mind? Yes. While technically possible, this would require MANY assumptions and is also impossible to DISprove. Therefore, Occom's razor comes in and says "no, that silly, don't even consider that as a possibility."

Then Glenn, followed by the other 5 Mercury pilots. Then Neil took the first step and we thought this is it we are reaching the stars and there is no stopping us. Years later I was part of the Search team in East Texas praying every time we found the astronauts. Congratulations to all the men and women around the world that made history with Webb.

this is just stupid, The Webb telescope was not always planned to be a megaproject. It was originally estimated to cost $4.96 billion and launch in 2014. But serious mismanagement and under-resourcing during critical early planning stages caused the ambitious spacecraft to fall behind schedule. After NASA restructured the project to launch in 2018 the total cost increased to $8.8 billion. In the intervening years, the program struggled to address serious technical problems, further delaying the launch to 2021. This final delay added yet another billion dollars to the total cost. do some research

Great video. However, a small quibble: at 4m55s, the graphics show the Webb remaining entirely in the shadow of the Earth and unexposed to the sun. This would actually be pretty disastrous for the Webb, as it would take a lot of fuel to remain in such a tight orbit around L2, and would also not have enough light for the solar panels to generate sufficient power for it to operate. In fact, the Webb will trace a large eliptical orbit around L2. By design, it will remain uneclipsed by either the moon or Earth for it's operational lifespan. This is so that its exposure to the sun is constant and the temperature won't undergo large changes, as is the case for satellites in orbit around Earth.

Why does it need to be at L2 behind Earth if it needs sunlight? Shouldn't it be at L3 or L4 facing away from light from the Earth but in direct sunlight?

@smittymcjob2582 2 роки тому
Learned this on another video: If we go out to L2 and put up a big sun shield, a big umbrella, then we can block out the Sun, the Earth, and the Moon all at the SAME time.

Dont worry, ariane 5 only failed once, the first time they launched it. Never failed since, i have personally seen at least 20 of them success :) And it's a 20 year old rocket that has been reliably putting commercials satellites in orbit since, the only real point of failure could be the change they had to do on the fairing, since the JWST is too big to fit in any rocket, even an ariane 5 that can usually easily carry 2 satellites at once

The thing about Webb that always blows my mind when I see it is that all the Hexagons look like 1 single mirror (which is the point). Whereas on the one model you show, you get the "bug vision" where each hexagon is slightly off from the others and so you get 12 different images instead of 1 unified image. And that, is brilliant.
@aemrt5745
@aemrt5745 2 роки тому
It is a really cool breakthrough. Until recently, telescopes were a single piece mirror. The hexagon technology has been used on ground based telescopes since the 1990s, resulting in a size breakthrough. The GTC at a whopping 10.4 meters! Get this, they are building the ELT in Chili. It will have a 30 meter diameter and have 798 hexagonal segments! Wow!

It's all fake, dude.... I don't expect you to believe me since you're 75. But 6 moon landings within 3 years 50 years ago.... And now we can't even go once? 19,000 satellite orbiting the earth yet pilots never see a single one in the sky? Flights in the southern hemisphere always coming up for "refueling" and then going back south? No one being allowed in Antarctica via the Antarctic Treaty because we gotta pretty the penguins? Seeing stars and clouds behind the crescent moon? How it that possible if it is a solid? Seeing planets inside our orbit like Venus and mercury at night? How is this possible? Curious? Check out Eric Dubay or Jeranism on UKposts. 🙏 Always be humble, man. Never think you know something. Be flexible with your belief system. God bless you.
