How long do you think James Webb will last? - Shoutout to Wondrium for supporting this video - check out their free trial here: ow.ly/iVzm50NvlJM
Around 30 years
Around 20 to 25,,,, I would say 20 years minimum
Hubble is still operating after thirty years, so James Webb should last around 30 to 40 years. but, the more complex something is the more things could go wrong. shortening it's life. space debris is also a problem, but james webb wouldn't have to worry about man mande objects, it is more likley that a small asteroid. thankyou for reading this.
today i realised i was meant to put my responses in the reply to the pinned coment.
I think 50 years voyager, still alive
From the first NASA theme LEGO set that I got was the LEGO IDEAS Saturn V Rocket with its exact total(plus the few space LEGO pieces that always comes in any LEGO Set we buy). My next set was the LEGO Creators Experts set of GRUMMAN's LM-13 NASA's Apollo XI's Lunar Excursion Module "Eagle". Then the third set was the LEGO IDEAS #029 International Space Station which I can say from my personal view was an enjoyable build and I'm amazed that LEGO was able to faithfully recreate the ISS at the scale it did with the LEGO pieces that they used for it. And my final NASA theme LEGO set was the LEGO ICONS NASA STS-31 Space Shuttle Discovery and Hubble Telescope.
And I hope that in the next wave of NASA themed LEGO sets is the James Webbs Telescope. or one of their more famous Programs Voyager I and Voyager II Deep Space Probes.
I mean, how in hell do they come up with these things????? So intricate, so specific, so mindblowingly functional.
Definitely some mind blowing stuff here!
Adding centuries of knowledge together.
That's possible by ignoring "superstition".
They talk about what all it can see in all the documentaries and Q & A panels I've watched. That's great and all but I wanna see how all the parts were theorized, constructed, and integrated. I would pay really good money to see that!
Through a many decades of extensive and non stop research. One of my Physics graduate friend got a chance of doing Post Doctoral Research in photon particle and dark current which is useful in terms of ultra high precision imaging, i just amazed by how many-many papers and world class research have been cited into making specific or ultra high gain camera completely possible.
As an acoustical engineer this application of sound didn’t even cross my mind…the people at NASA are seriously next level
That's why you're wherever you are and folks at NASA are in NASA
Your tiny polytheistic brain won't comprehend this level of science
@@awesomensickestcontent1659 thats why you are stuck in your moms basement
@@awesomensickestcontent1659damn bro no need to be an ass about it.
@@awesomensickestcontent1659 you're weird lil bro
This gives a whole new level of meaning to “that sounds cool”
😂😂😂
Took me a sec!
That sound cools instead of that sounds cool
@@Frosty-gaming name checks out
@@JangoAC cooooool😎😎🤓
I never thought that sound can be used to cool down the temp, that's incredible !
Pretty mind blowing stuff!
Sound= movement
Heat=movement
It makes perfect sense
Sound is a fancy word to say wave(?). I don't think the designers used the word sound to describe their system.
that could explain how we get chills from music?
I find the work of the engineers on the design of this telescope really incredible, the level of detail you have to go into to avoid it being completely unusable. I imagine it will last between 30 and 35 years, but I hope even longer.
30 + years would be great to see!
Can we put that cooling mechanism to our quantum computers?
@@_________________________.- maintenance of such temperature is nearly impossible for long time on earth
@@_________________________.- nope baby
@@_________________________.- IBM has cooling system , which is said to be coldest spot in universe , so why do we need that ?
That is incredibly fascinating and you explained it rather well to people who might not understand physics much. I think it will last for 30 years, Hubble will last for longer since its launch but it was repaired and improved in the meantime. If something goes wrong the technicians will have to just work around the issue
Thank you so much! I'm so glad you enjoyed the video. Great prediction as well! Good luck in the giveaway 🙌
I didn't think about that! Yeah I suppose if anything falls up there, they can't repair it now. Unless they develop another space probe for the sole purpose of maintaining Webb. Like a robot mechanic lol
The quality behind this video is phenomenal. Explaining such a complex item so simply. This engineering seems like pure magic! Physics is so cool
Thank you so much. I'm so glad that you enjoyed the video. I really enjoyed making it as well! So cool!
Cannot even imagine the efforts taken by the team of james webb....! Simply awesome...!!
💯💯💯
Look up "acoustic cooling". There is an air conditioner you can build for cheap that cools air this way.
Power of human team work, which we are incapable off day by day, religion, country, race, pandemic etc.
And there's some so called knowledgeable person saying these are fake
I think the engineering on the JWST is incredible, I love finding out all of these little extra details. I think it will last for at least 25 years in some capacity.
I look forward to seeing the JWST tech trickle down to the everyday person. For example new home AC tech based off of sound would be cool.
@@danielray6574 it definitely would be 'cool'
I've always been curious how a single camera can pick up so many wavelengths and sort them into different views of the same image. this video was surprisingly interesting
Because what the animation shows is not the imager but the medium-resolution spectrograph section.
0:11 The light is initially sub-divided (roughly) by three sets of filters which reflect some wavelengths but transmit others.
0:14 shows the four light paths (each of which deals with a different range of wavelengths) striking the gratings. The gratings have very fine grooves which spread the light into a spectrum - in much the same way that the tiny dimples on a CD do.
0:16 Each detector records the spectra from two channels.
The whole spectrum is recorded in three observations (because the filters are very specific) with enough overlap to line up the individual spectra accurately.
I can't even comprehend this level of complexity. Very well explained for people like me who doesn't have a single idea how to cool things down even more. This is SOOO clever! Everything you explained make sense. That's why it is so mindblowing. Realizing the engineering behind this....
0:11 props to the cameraman for moving faster than the light here.
As just a year 2 engineering student, I just can't believe we humans managed to engineer and create such a beautiful piece of equipment. The things these people managed to accomplish is just...it makes me speechless
I just discovered this channel and I'm in COMPLETE AWE of the visuals in every video! This is Oscar-winning level of work!
Thank you so much! It really means a lot that you've been enjoying my videos!
This video is so well done, I am blown away. Flawless explanation accompanied by incredible visuals. This is how you make a top notch educational video.
Thank you so much for such a kind comment. It really means a lot that you enjoyed the video!
Such an informative and detailed video. Yet things are explained in such simple terms. So nice to watch it.
Thank you so much. I'm so glad you enjoyed it!
How tf could anyone have thought of that at all?
Pretty mind blowing stuff!
Price tag 🙃
Everytime I watch a video like these I get amazed by the sheer amount of engineering and thought put into certain machines, it really shows that we've gone very far in our 'tech tree'. The JWST really is one of the most awesome things we have done as a species and I hope it'll stay functional and operational for a long time, I personally believe it could get to 20-30 years at the most, considering there's a lot of debris in space and this is a rather fragile machine in comparison to all of the hazards that could damage it to a point of no return.
Around 27 years. This is my second time entering these giveaways and I think it’s nice what you do. It’s also fun to learn about space(something I’m interested in)because of all of the things out there
Amazing video, I love and appreciate the detail and effort you put into these videos
I'm a Physics major undergoing my Bachelors and to see the simple concepts of Gas Laws in effect at the JWST is simply awesome.
The visuals in these videos are fantastic and do a really great job at helping our understanding of the complexities that these topics bring, truly great videos! NASA originally predicted the JWST to only last about 10 years but with how smoothly the positioning went when reaching the Lagrang point, they saved some fuel. I think that this little extra fuel will help push the telescope to around 15-18 years hopefully!
You hv such a talent in communication, always asking the right questions at the right time and answering them. Great work
Thank you so much. I'm so glad you enjoy my content. It really means a lot!
I must've rewound this video a dozen times to re-watch parts. This was an excellent compilation of interesting information about the telescope. The Helium-based cooling system is remarkable, and I think it deserves its own video.
Wow great explanation of how they've reached such an unimaginable level of cooling! Really pushing the boundaries of science and engineering! Hopefully the James Webb will last for 20 years at least as it add on to our understanding of the universe!
20 years or more would be great! Here's hoping!
Even with chemical engineering training, I found this so hard to keep up with
In principle, the process they designed mirrors the processes we see in chemical plants on earth but the way they went about all this was so mind blowing
This was something I never really gave a thought to, and now I'm amazed of all the engineering and design behind this telescope. I'm really glad this got recommended to me!
It's pretty amazing how many seemingly small things go into these amazing feats of engineering! So glad you enjoyed the video and thanks for taking the time to comment :)
Learning a lot from primal space especially the videos showing in depth of each aspect. I haven't learnt so much from school. Thank you team
So glad you're enjoying the videos and learning a lot! Means a lot!
I love to see JWST operating for more than 30 years and just seeing old satellites withstand more than 5 times its design lifespan it probably will. Also great job dude :D
30 years would be pretty great to see! Thanks for sharing your prediction and so glad you enjoyed the video! Good luck in the giveaway :)
Thanks again for this great and detailed video!! I believe and hope it will be functional for more than 40 years!
Thank you so much! So glad that you enjoyed it!
The way you explained is really fascinating and easy to learn about. Great JOB !!
Thank you so much! So glad that you enjoyed the video!
I'm glad that I came across your channel. The way you explain stuff is commendable.
Thank you so much! I'm so glad that you're enjoying the content and my explanations. It really means a lot.
Nice videos! It’s really interesting to see how far to the limits can those engineers go.
Thank you. I'm really looking forward to following the progress in the future!
@@primalspace Me too!
Woww! That was a really brilliant explanation! I always wondered about the big hexagonal plates, but never realised that so much work was also going inside the layered body.
Being close to Earth, JWST can be easily operated as compared to older satellites like Voyager 2(which is likely to last about 2 more years). However, JWST potentially may last minimum 10 years. But, I wish that it last longer.
Definitely hoping for longer too, but excited to follow the journey of James Webb. Thank you for sharing your prediction and so glad that you enjoyed the video! Good luck in the giveaway!
JWT детский сад по сравнению с тем чего мог достить человек если бы бюджеты тратились на гуманитарные проекты а не на военные. 1 Годовой бюджет только ... привышает растянутый на десятилетия проект JWT в 53 раза ...
its honestly so mind-blowing that people are not only smart enough to understand the problem at hand but to also be able to solve these insane problems. iz crazy
Absolutely mind blowing! And there's SO much more to learn and discover. I can't wait!
The fascinating amount of engineering knowledge and capability to come even close to building a machine like this is truly remarkable work, really goes to show that science is absolutely marvelous and almost limitless
This is incredible, my brain got lost trying to understand this system even after reading about it several times.
But you in just 9 minutes made it so clear that even a 12 year old kid could now know what is happening inside the Webb telescope 🌟 my mind is blown.
Thank you so much! It really means a lot that you enjoyed the video and my explanation.
@@primalspace The lip analogy on the Joule Thompson Effect helped me understand the effect much better. Thank you! I also am debunking Level 3, a flat earth documentary.
Your explanation of noise blew my freaking mind
I love the animation you have made in this video and the simplicity of explanation even a laymen can understand... great work, sir...
From my pov as the technology used in this telescope is very high and the hubble telescope is still in a working position, so probably 25 to 35 years!
25 + years would be so great to see. Thanks for sharing that prediction and so glad that you enjoyed the video and my animations!
Incredible video! Thanks for explaining the amazing engineering behind the Webb Telescope!
Thank you so much 🙏🙏 So glad you enjoyed it!
Even though the mission length is only 5-10 years, I’m hoping it’ll continue working for another 20-25 because of the great photos it sends back
Absolutely! I would love to see 20 years at least!
I discovered your channel today and its really awesome. I even shared the link on insta and many really liked it. Waiting for your next video....! Techonology is rapidly improving as we speak but i guess even if newer more advanced telescopes are put into orbit, james webb will still be operational. So i feel that it might last for more than 50 years.
50 years would be so amazing to see! Thanks so much for sharing your prediction and sharing my channel as well. Really means a lot. Glad you enjoyed the video and good luck in the giveaway!
Its amazing how such a small thing can make something of such power cool down. I can't imagine how hard it must have been for the engineers to design the cooling system while maintaining other parts of the JWST.
Thank you for explaning this amazing and not very talked about topic of the James Webb telescope (also I love the animations). I think that the James Webb Telescope will last between 25 and 30 years if NASA does their best with the telescope.
Thank you so much! I'm so glad that you enjoyed the video and my explanation. Thank you for sharing your prediction as well. Good luck in the giveaway!
"How NASA cools James Webb camera to almost absolute zero" is a better and more accurate title.
That use of standing waves for temperature exchange was so cool. ;)
I remember first learning about Webb in the early 2010s. I was so excited!
I think that the James Webb telescope will definitely last longer than the 10 years expectancy rate, as long as it is navigated and used in a proper way, to avoid critical damages, unless it is intentionally shut down. The James Webb is definitely a big step for space exploration and i really look forward to what it brings us. If used and monitored well, and if it can be theoretically refuelled, it will last more than 35-40 years.
Hubble is used for ~30 years and while still usable we're replacing it, simply because we could built a better one (JWST). I think JWST will be replaced before 30 years(maybe even 20) just like Hubble, not because it's broken but simply because we're able to built the much better one once again.
What a brilliant way to cool something. I wonder if we could use this design in other applications... like refrigerators and air conditioners.
Different heat pump designs all have trade offs. While pulse-tube cryocoolers can achieve extreme reductions in temperature, they are not very energy efficient and you wouldn't choose them to do something like maintain the inside of a fridge 20-25 C below ambient.
@@chaz720 Where does the JWT get the energy to power these? Do they need to run constantly?
@@kperry5000 Solar arrays and lithium ion batteries. The vehicle has a total of about 2kW to work with and on average uses about half that. The cryocooler runs continuously and I think draws a few hundred watts in steady state if I remember correctly. You can search for "cryocooler specific power" for discussions/papers on the topic.
To the animator of this video. There are so many subtle changes that go on to explain with accuracy, well done!
Very informative and detailed videos! Keep up the good work.
Hopefully jwst will operate for atleast 10 years to further our knowledge of the cosmos! (and keep supplying us those great photos of course)
10 + years for sure! I can't wait to follow the journey. So glad you enjoyed the video and good luck in the giveaway!
James Webb is an amazing piece of engineering. With its extremely advanced systems I think it will be in service for at least another 60 years.
60 years would be pretty amazing to see. Here's hoping!
Since it cannot be upgraded, in 60 years all of these technologies will be considered ancient by then
I think that the James Webb telescope will continue to work till 25 years or so.
Btw awesome video and visuals!!
25 years would be great to see! Thanks for sharing and so glad you enjoyed the video!
This is so cool, thanks for the video! Great explanation
Thanks so much! Really glad you enjoyed it!
I can't imagine how they come up with this stuff, truly mindblowing!
Thanks for explaining the amazing science behind the JWST! I think it'll last for at least 20-25 years.. Saw it's entire launch and opening from NASA's website. The first pics from it were amazing!
Absolutely incredible! And a great prediction. So glad you enjoyed the video and good luck in the giveaway!
Well, the James Webb Space Telescope is designed to operate for a minimum of 10 years, but I think it has the potential to operate for much longer than that. Limiting factors are the amount of fuel on board, the functioning of its various components and the life expectancy of its instruments.
The helium will wear out after 5.5-10 years...sadly
Just think about a helium baloon.....helium degradation will be the downfall of JWST unfortunately. Wish it lasts decades but the helium isnt on our side....
Excellent video, simplistic, easy to follow, and informative.
Thank you so much! So glad that you enjoyed it!
It just amazes me to know how little details go into something so big, and more than 95% percent population does not even have a tint of idea of how these thing works, crazier thing is they aren't curious enough to look into too.
Truly amazing - I can't imagine not needing to learn and understand every single detail haha.
Kudos to the smart scientists and pushing the boundaries. Explained superbly and I hadn’t known about this. Given the Hubble has lived double the time it was expected and hoping this will continue to go on well, I expect it go providing us mind blowing pictures and answer more questions for at-least 20 years.
Thank you for sharing your prediction - I'm so glad you enjoyed the video! I would love to see James Webb last 20 + years! Good luck in the giveaway!
I love the content of this channel and how insightful it really is. I think that the space web will be in operation for at least 30 years and might have to undergo maybe some type of upgrade by a manned mission in the future. I think this will be one of those technologies that will keep on giving for many years to come.
Thank you so much. I'm so glad that you enjoy the content here. And thank you for sharing your prediction for James Webb. Good luck in the giveaway!
I am so excited to see what new limits of technlogy we can reach for future space projects
Same! Really looking forward to what's to come!
Surely this thing will thing will be up there for a while! So many corners of the universe to explore.
Here's hoping! Can't wait to follow the journey!
Never wouldve imagined that one of James Webbs biggest design challenges had to do with noise reduction and atom stabilization, crazy to think that these tiny systems are essentially what makes this telescope so great and enables it to take such cool photos. I think the telescope will last atleast another 5 years for sure, and if its still holding up till then I can see it pushing for as long as 15 years before the batteries give in and won’t be able to provide enough power for major operations. Hopefully longer tho!!
Are the electrical systems not powered by solar panels on the 'hot' side of the sunshield ?
Let's admit we all tested the warmth and coolness of our breath
Haha love it!
This is literally the 'coolest' vid on UA-cam🙌What an incredibly mind-blowing vid. The way you explain and present this ingenious engineering is simply amazing!! Wow, just WOW!! Thank you so much. 👌
Thank you so much for such a kind comment! Really glad that you enjoyed the video (and my temperature puns haha)
@@primalspace Awesomeness 👌
the transition to the ad was really smooth!
Haha thanks! Glad you enjoyed that one!
does James Webb listen to lofi *chill* beats?
😅😅 I really hope so .. they are the coolest.
I love that it this is soo complex but is easily understand by your videos❤❤ and i think it will last for 17 years.
Thank you! Really means a lot that you enjoyed the video and my explanation. And 17 years would be great to see! Thanks for your prediction and good luck in the giveaway.
What you describe there is not a pulse tube cooler, but rather a thermoacoustic cryocooler. A pulse tube cryocooler is more similar to a stirling cycle cryocooler but replacing the displacer piston with a empty tube with a capillary tube or an orifice valve at one end leading to a buffer volume, this capillary tube is calibrated in diameter and lenght/valve is set to create a 90deg phase shift between the wave in this tube and the power piston, just like in a stirling cycle.
This is absolutely amazing. Having worked in industrial electronics, I would think the telescope has been designed to operate for at least 20 years. With all of the careful engineering, however, I think it will last far longer; possibly 60 years.
0:06 The light path shown is not that for the camera but for the medium-resolution spectrometer. The camera (imager) is the top third of MIRI, the mid-section is housekeeping and electronics, the lowest third is the MRS unit.
It is so fascinating and so exact. It's almost mind-boggling how humans have created such technology and yet explain it so simply. My favorite part was definitely how they used multiple different effects to continuously cool the gas. I could see James Webb being fully operational for the next 30-40 years as our technology is always improving and will simply outperform Webb in the future!
30 + years would be pretty amazing to see! Thanks for sharing your prediction and good luck in the giveaway!
Very interesting video. Since young, I've always wondered about why when we 'hoo' it's cold but when we 'haa' it's warm. I hope the telescope will last for at least 20 years and continues providing us these stunning images
20 years would be pretty amazing to see! Thanks for sharing your prediction and good luck in the giveaway!
My mind is blown 🤯🤯
So simple, yet so complicated, the extreme engineering 👍
bro these videos are so binge worthy
Learned a new thing today (Joule-Thomson effect). Thanks!
So glad you were able to take something away from this video. Glad you enjoyed it! Cheers!
I love your visualization of the cooling mechanism.
Thank you so much! Really glad you enjoyed it!
I think there are two misconceptions in the video at around 7:50 .
The Joule Thompson effect doesn't work because of the change in diameter in the tubing, it does because of the drop in pressure (dT/dp) due to the throttle.
When blowing air through the mouth to cool down food it isn't the JT effect in action. the airstream is just much faster compared to blowing through a wide open mouth (eg. when warming up your cold hands with your breath). The airstream picks up more of the surrounding air reducing it's temperature down from body temperature to closer to roomtemperature.
Otherwise the video is very well made and enjoyable as well as informative.
This video is absolutely crazy, The grafics do a lot in helping me understand whats happening inside the cooler, and the physics and engineering principles that are being used. Im all in for space exploration as it brings technology and human knowledge to the limit, thus bringing great innovations that we can later use in our society!! Im not sure on how long it will last, but given the extreme care and precision that go into these kind of projects im sure it will outlast the intended mission duration.
Definitely hoping for it to outlast what's been predicted so far! Thank you for sharing your predictions and so glad that you enjoyed the video!
So much can go wrong, yet everything went right. Amazing. Science is a beautiful thing to watch work.
Agreed!
Great video! Unfortunately to the best of my knowledge the explanation of the Joule Thompson effect isn’t quite accurate in the final cooling stage, though I could be wrong. Blowing air through your mouth is not related to the Joule Thompson effect as it only applies to real gases at extremely low temperatures (such as this case) or very high pressures. Additionally, it’s not due to the rapid lowering of pressure that it cools but rather that the rate of which the pressure decreases is lower than that of which it’s volume increases. In the Joule Thompson equation H = U + PV, the enthalpy is constant, thus the total internal energy (hence temperature) would only decrease if PV increased, and the only way for PV to increase given a reducing pressure is for the volume to increase at a higher rate (which occurs as a result of its intermolecular forces).
This is incredible... I think it can last for another 15 years... and we will witness incredible things and the discoveries will change our understanding at core level
15 years would be great to see. Looking forward to following the journey! Good luck in the giveaway!
easily, the best video on this channel by far!
Thank you so much! Really glad you enjoyed the topic as much as I did!
I love all the little details in JWST. I'm sure all spacecraft have their own intricate specialist parts but you could probably fill an entire year explaining all of the subsystems of JWST alone. I sure hope that all the electronics and subsystems survive long past the planned mission length, but given that its propellant will be running out at some point I feel like 20-25 years would be great.
20 + years would be great to see! Thank you for sharing your prediction and good luck in the giveaway!
What a great video! I felt that I was inside a Home Depot’s commercial in 2074, selling some telescopes
so amazing to learn how a series of facilities combine together to cool down the temperature
So glad you enjoyed the video!
incredible explanation, theese good for any project replacement cycrocooler
Thank you so much. So glad you enjoyed the video.
Thanks for such a astonishing explanation as a student of grade 9 myself i have full faith that videos such as yours and the deep ocean of information that the internet possess will lead the next generation of humanity like us to a future brighter than any thought and beyond our own imagination specially in astronomy i hope to see videos from you on teraforming mars as well as venus cause i feel that venus has great potential. For the lifespan of james webb i think it will last no less than a solid 50 yrs cause of the advance tech and engeneering it has i feel that it could last even longer but as its repair is not easy it might not last too long than 50 yrs but who knows hubble overcame our expectations so might james
Great video as always. Can you please do a video on time traveling. Like I have heard that we have found theoretically how it's done but physically it is not implemented yet
Could you explain protons, neurons, negative energy and anti matter and such? It sounds so very difficult but you explain very clearly
James webb telescope is an engineering marvel. I cant even comprehend how much complex tech is used in such machines. I think the telescope will last about 17 years but also think that maintenance will also play a vital role in its life expectancy.
Absolutely! 15 + years would be great to see. Here's hoping there are no issues!
really smart heat management design,thx
Great video on explaining the cryocooler. Enjoyed watching it, Thanks. It will last for about 20-25 years.

This video is a wonderful work of art.
And the James Webb space telescope is an incredible feat of engineering architecture and intelligence .
Thank you so much! I'm so glad that you enjoyed it!
JWST and the technology behind it is just awesome
Absolutely agreed!
It's incredible how this works and real engineering did not tell me something about this and this is absolutely amazingly blowing my mind and I love it! it's amazing and purely just wonderful
Absolutely mind blowing stuff! So glad you enjoyed the video!
@@primalspace I did thanks
Awesome explanation, keep it up!
Thanks so much! Really glad you enjoyed it!
