This could have been far better designed. Northrup Grumman should have their company seized for extorting taxpayers and refusing to cooperate with oversight over 2 decades
@@EarthCreature. Yep. Even a folded petal system would have been far superior and far simpler. This is how Northrup Grumman justified taking $20B. They also refused to let NASA oversee their progress because I guess taking our money is easier that way. Think it was 2010 they clutched their pearls at the thought of us ensuring our project got made on time.
🔴UPDATE: The sunshield covers have been released and rolled back to their staging position. This procedure alone required several mechanisms to fire just exactly right and they did! Thumbnail updated :)
If there is lets say a MAJOR issue that cannot be corrected...couldn't JWST technically burn to return to earth orbit so at least it could be serviced and then fired again later back to L2? I know this would be insanely costly but much less than losing the entire thing.
I don’t know if it has enough delta-v to turn around and burn for home but even if it did, doing so would expose the telescope to the sun, causing it to overheat well beyond limits. That would render the telescope unusable at that point.
I worked on the sunshields for this amazing project. Particularly on seaming the Kapton film together into 3d shapes, and also packaging and deployment. Truly an honor to work on.
One of the clearest and most straightforward explanations I've seen. This answered several questions I had about the design and why certain features exist. Thank you.
Yeah and that's all they have is talk, no actual physical proof.. it's all in the language and the maths .. you can tell earth is so curved because it looks so flat right?
The speaker in this video does an OUTSTANDING job. His voice, expressions, and gestures are perfect. I follow a few science RUclips channels, and I've sort of resigned myself to the croaking and twitching of the people in front of the camera. This guy, by comparison, is a pleasure to watch and listen to.
Gotta disagree. He said the telescope might be moving too "slow" rather than too "slowly" when talking about the second burn and its importance. That's a pretty big language fail in not knowing the difference between an adjective and an adverb and far from perfect. I was really into it before he said that though.
🔴WE HAVE A TELESCOPE! I was making a "halfway there" video following yesterday's sunshield deployment, but then they went and moved up the secondary deployment to today, TWO DAYS earlier than planned. In the meantime, the most critical deployment since the solar panel is out of the way! Without it, there's no way to use Webb. but now it's possible!
I thought it would be a telescope once the two side panels of mirrors deployed? Overall this is great news as I still feel scarred from the Hubble mirror debacle back in 1990! lol
@@pipertripp you sound like a fellow Australian! I was so anxious with the delay this morning, but with 250/344 single point failures and the worst of them almost behind us, my confidence has soared.
I have been searching for this very type of information for 2 days now. I know there are videos that describe the deployment and manouvers made before launch of the telescope, but I want the most up to date information and explanations in layman's terms. I will share this video for sure.
As a kid I witnessed the first moon landing and saw the capsule up close after it's return. Back then it seemed rugged, crude, built to withstand heat and a lot of forces. In contrast this space instrument is an example of an extremely precise and well thought out combination of structures that operate in unison so that each component can play its vital part. Like the Apollo capsule, it needs to cope with the extreme environment of space, yet this seems to be 'brain in stead of brawn-design' . I am very very impressed indeed. I can't wait to hear & see more about it's progress. Thank you for your presentation. Willem
Willem. At 73 I too remember the first moon landing as well as the headlines (newspapers..yes paper) of Sputnik. My father told me of the very first fly-over, he witnessed as a kid, of an airplane over New York. What we're seeing now is spectacular! And just as ground-breaking. My only concern is that there are SO MANY critical things that have to work perfectly the first time. Keeping my fingers crossed for all to go right!
Amazing content! Thank you for this. Definitely subbed to you. I will be closely following this marvelous piece of technology bringing a new era of cosmology and astronomy to us all. Feeling a bit anxious about everything working as planned, for this to become the most important instrument for us to understand the universe, instead of becoming the most expensive and horrible tech catastrophe. The live launch had me gripping my armrests pretty tight 😟😄
I'm somehow so anxious about each steps of this mission because my biggest wish for 2022 is to see my best musical buddy being able to see the first pictures out of Webb. He worked on building one of the pieces of this telescope, and talked about it for so long each time we were jamming. Sadly his health went deep critical a few months ago, and may have only few months left. So happy he's still here and finally saw the launch. Let's wish now for him to see the first stars pictures in a few months. I really wish
This was the best JWST explainer video I saw! No distracting vfx, no music, no bs filling extreme oversimplifications. Magnificent work sir. Subscribed
🔴UPDATE: Sunshield tensioning underway! After going late on New Year's Eve, the team took the day off on Saturday and then Sunday elected to better characterize Webb's behavior now that it's in space. So sunshield tensioning was delayed until today and began this morning. This will continue for the next 2-3 days until fully deployed! Thumbnail updated :)
@@jc4evur661 There are always slight differences between the way the spacecraft systems operate in space, versus during ground test. Although they try to replicate the space environment as well as possible during ground test, it isn't possible to get this perfect. They are examining lots of data - temperatures, battery condition, power usage, solar panel output, etc., to make sure everything is within required ranges. As of Monday Jan. 3rd, they have made two tweaks: 1. Solar panel regulators have been adjusted to match power needs better. These were initially set to factory defaults, but they have now been individually optimized. 2. Shield tensioning motors were a few degrees warmer than they wanted, so they adjusted the spacecraft attitude for a while, to reduce sun exposure and get them down to the desired temperature.
This is a very educational video. Like many others, I've been waiting for this to launch for a long time. The calculations and planning put into this is impressive. I hope everything goes well, and this works as promised.

Absolutely superb overview of the initial stages of the JWST deployment. I'm glad my 20" dobsonian reflector does not have so many critical steps to get it up and running!
Thanks a lot Christian, always the most informative experience to watch the LaunchPadAstronomy channel. I`m praying that everything works fine during upcoming weeks for the JWST.

It's so saddening to see some people giving hate to this extraordinary instrument. I'm sure it's difficult to quantify, but it would be a great video to see how these science tools affect our society, and how they're more like an investment, rather than a waste of money.
it's almost unbelievable that some people consider Webb or other nasa projects a waste of money... NASA, ESA, and other technology/science groups should all have UNLIMITED budgets and no limits
I _knew_ I could trust you to keep us fully updated on the nitty gritty details. Im going to sweat each day mentally checking off points of failure till we finally get a commissioned observatory. This is the most exciting space event for as long as I can remember. Only a half dozen or so top this.
As always, great video. Thank you for covering the deployment steps in so much detail! I have not seen any other video do that. Looking forward for the detailed video on JWST's optics.
Thanks for another great JWST video Christian. Also, exciting news: As of tonight 28 Dec BOTH the Forward and Aft Sunshield pallets have been successfully deployed!
Im just a welder - mechanic but I've been checking up on this project since the beginning and I can't wait to see the first images . Fingers 🤞 . Good luck
You know, I scrolled past a bunch of comments and happened to see yours. And I finally crated a channel just so I could reply to it. A whole lot of people who are "just welder - mechanics" are the ones who built this thing. I spent 10 years as a steelworker and 34 years as a design/consulting engineer, and a drawing doesn't do anything; without the best craftsmen in the world here in the US, nothing gets made. So tip of the hat to you, don't sell yourself short. Keep laying down them rows of dimes - it's an art and a science I really respect.
Great video! I wasn’t sure how the sideways view was gong to work. Your’s is the first video to explain how it can see everything over the course of the year. Simple and amazing.
Great video ! Left a subscription. I'm wondering how they get precise enough position readings that far away from Earth and what the margin of error for position determination is, to get James Webb safely into its L2 orbit.
They are measured from Earth, using the radio link. Distance is by sending a signal to JWST, then timing the echo. The Doppler on that gives the speed (down to mm/s). Lateral position is a bit less accurate if they use one station on Earth, but they could triangulate.
@@Capt.Turner Lateral position would've been sorted out within the first 2 burns when it was close enough to Earth for regular old triangulation. The farther out it gets, the more fuel lateral corrections would take.
If it's fully deployed and then Webb reaches the L2 point and the final booster manoeuvre is initiated to make that almost 90 degree change in flight path, at that speed, wouldn't there be potential damage to the structure? Of course... I know they've thought it through! I really want it to go all the way successfully.
Good question. I’m guessing they’ve taken the accelerations into account, and it’s actually not a very high thrust maneuver because by that point it will barely be moving fast enough to reach L2!
Beatiful science and technology behind Webb`s deployments, it is amazing the number of nanomotors, pulleys and nanotech. The precision requieres and the synchronism achieved by electronics and controllers is incredible. The stages for deploying the sun shield is a particular engineering success
I think there was an article today from NASA stating that the perfect delivery from Ariane 5 and ESA and the saving of fuel because of that extents the mission duration over the 10 year mark already. 🙂
I'm 62 years old. As a young boy I watched the Apollo missions to the Moon with wonder. I remember Skylab and then the Russian's years of success with their space station Mir. And then the era of the Space Shuttle. Over the decades I watched the Voyagers' encounters with the planets. I remember Hubble's launch, the initial disappointment, and then its repair and maintenance by the Shuttle. And we have now had several rovers trundling across Mars, Cassini and a probe landed on Titan, and nearly two decades of the ISS. I remain in awe of what humanity has achieved. In some ways the JWST is ambitious beyond all of this. I just hope that it's insanely complex deployment goes well and that I live long enough to have my mind blown once again by what we will learn...
Humanities achievements are awe inspiring. Hopefully we don’t blow ourselves up because people keep arguing over who controls which crevice of the Earth.
As a project manager, I am in absolute awe at the logistics and planning that must go into these Nasa projects. While there is beauty in "Keep it Simple Stupid" there is pure wonder when something insanely complicated executes flawlessly and delivers far greater results.
Now I understand why James Webb Telescope was delayed countless times for years. One single error and poof... there's your $10B space junk. This is a masterpiece of an engineering, so much complex ways for it to work, mad respect for those who made this possible for us earthlings to know more of the secrets the universe has store for us, it's gotta be mind boggling to even comprehend about.
oh wow.. i was wondering when it would unfold, but no one in the audience of the livestream i was watching answered my question. now i see it's not a simple answer :-)

I'm from Germany and i love astrophysics, that's one of the best decleration of the JWST i ever seen, thank you for that amazing work!
I _knew_ I could trust you to keep us fully updated on the nitty gritty details. Im going to sweat each day mentally checking off points of failure till we finally get a commissioned observatory. This is the most exciting space event for as long as I can remember. Only a half dozen or so top this.
This has got to be one of, if not the best space channel. Wish I had money to support.
Thank you
Giving flat earthers migraines.
As always, great video. Thank you for covering the deployment steps in so much detail! I have not seen any other video do that. Looking forward for the detailed video on JWST's optics.
Thanks for another great JWST video Christian. Also, exciting news: As of tonight 28 Dec BOTH the Forward and Aft Sunshield pallets have been successfully deployed!
This was the most in-depth JWST video I've seen and was presented in a way I could understand. Thanks! 🔭
Im just a welder - mechanic but I've been checking up on this project since the beginning and I can't wait to see the first images . Fingers 🤞 . Good luck
You know, I scrolled past a bunch of comments and happened to see yours. And I finally crated a channel just so I could reply to it. A whole lot of people who are "just welder - mechanics" are the ones who built this thing. I spent 10 years as a steelworker and 34 years as a design/consulting engineer, and a drawing doesn't do anything; without the best craftsmen in the world here in the US, nothing gets made. So tip of the hat to you, don't sell yourself short. Keep laying down them rows of dimes - it's an art and a science I really respect.
It doesn’t matter if you’re a welder or a garbage man or the head of the fbi or whatever, this telescope is an advancement for all of mankind 🙏
Many thanks for this explanation with outstanding clarity.
Very well presented and articulated! Best one on RUclips!
Great video! I wasn’t sure how the sideways view was gong to work. Your’s is the first video to explain how it can see everything over the course of the year. Simple and amazing.
You just answered several questions I had that I wasn't seeing addressed in the many other JWST videos I've been watching. Thanks!
This is the best channel for information regarding JWST!
Wow, thank you!
Nothing ever goes exactly the way we envision it. That's a simple fact of life. But wouldn't it be mind-blowing to hear that *everything just worked?*
Thank you! I’ve been looking for this information and couldn’t find anything nearly as concise and cleanly delivered. I subscribed!
Great video ! Left a subscription.
I'm wondering how they get precise enough position readings that far away from Earth and what the margin of error for position determination is, to get James Webb safely into its L2 orbit.
They are measured from Earth, using the radio link. Distance is by sending a signal to JWST, then timing the echo. The Doppler on that gives the speed (down to mm/s). Lateral position is a bit less accurate if they use one station on Earth, but they could triangulate.
@@zounds010 Yeah, the lateral part is what concerns me. Not much of a triangle at that distance.
@@Capt.Turner Lateral position would've been sorted out within the first 2 burns when it was close enough to Earth for regular old triangulation. The farther out it gets, the more fuel lateral corrections would take.
Very informative explanation. Comprehensive AND comprehensable at the same time. Excellent!
If it's fully deployed and then Webb reaches the L2 point and the final booster manoeuvre is initiated to make that almost 90 degree change in flight path, at that speed, wouldn't there be potential damage to the structure? Of course... I know they've thought it through! I really want it to go all the way successfully.
Good question. I’m guessing they’ve taken the accelerations into account, and it’s actually not a very high thrust maneuver because by that point it will barely be moving fast enough to reach L2!
@@LaunchPadAstronomy Thank you! Yes, if it slows down by that much, then all is well!
Beatiful science and technology behind Webb`s deployments, it is amazing the number of nanomotors, pulleys and nanotech. The precision requieres and the synchronism achieved by electronics and controllers is incredible. The stages for deploying the sun shield is a particular engineering success
I think there was an article today from NASA stating that the perfect delivery from Ariane 5 and ESA and the saving of fuel because of that extents the mission duration over the 10 year mark already. 🙂
NASA has said that refueling Webb would be difficult but possible robotically.
Best video I’ve seen on Webb by far. Look forward to more!
Thanks 🙏
I'm 62 years old. As a young boy I watched the Apollo missions to the Moon with wonder. I remember Skylab and then the Russian's years of success with their space station Mir. And then the era of the Space Shuttle. Over the decades I watched the Voyagers' encounters with the planets. I remember Hubble's launch, the initial disappointment, and then its repair and maintenance by the Shuttle. And we have now had several rovers trundling across Mars, Cassini and a probe landed on Titan, and nearly two decades of the ISS. I remain in awe of what humanity has achieved.
In some ways the JWST is ambitious beyond all of this. I just hope that it's insanely complex deployment goes well and that I live long enough to have my mind blown once again by what we will learn...
Humanities achievements are awe inspiring. Hopefully we don’t blow ourselves up because people keep arguing over who controls which crevice of the Earth.
@@mensaswede4028 Amen to that, brother...
I'm also 62. The lunar landing in 1969 with the technology at that time is far beyond anything since, including JWST
@@mensaswede4028 nuclear war is inevitable
@@James_the_Builder 😬🌚
This was a super video it was hard to tell where we are with the mission as well as what exactly happened but u explained it well
As a project manager, I am in absolute awe at the logistics and planning that must go into these Nasa projects. While there is beauty in "Keep it Simple Stupid" there is pure wonder when something insanely complicated executes flawlessly and delivers far greater results.
I'd bet the flowchart is on the biggest wall that NASA could find...
Awesome video and thanks for the update on the DTA. Happy New Year!
And a Happy New Year to you as well!
Stunning narrative. Thanks a lot.
Thank you!
Your videos about the JWST are among the most in depth, information-packed and best presented. Keep being awesome!
Thanks, I'm so glad you liked it!
@@LaunchPadAstronomy thanks
Great description for the average science/astronomy buff. Very well presented! Thanks!
“Hey Jerry, you did remove the⚫️ lens cap before launch, didn’t you?”😳
I just discovered your channel! This was beautifully narrated with a fantastic script and supporting imagery! I’m an instant subscriber.
Now I understand why James Webb Telescope was delayed countless times for years. One single error and poof... there's your $10B space junk. This is a masterpiece of an engineering, so much complex ways for it to work, mad respect for those who made this possible for us earthlings to know more of the secrets the universe has store for us, it's gotta be mind boggling to even comprehend about.
WHAT A TIME TO BE ALIVE!! I'M 29 YEARS OLD AND HAVE BEEN FOLLOWING SINCE THE BUILD BEGAN!! LETS GO!!! WOW!!!
If NASA can drop a car-sized rover onto Mars from a rocket propelled pogo stick I am sure this one will be easy! Great video btw.
when you put it that way, it sound much better for JWST... lol.. 🍻
Absolutely brilliant and highly detailed explanation of the JWST. A must for any space enthusiast!
I now have JWSTDA - James Webb Space Telescope Deployment Anxiety.
Me, too!
I'm with you..
Hi Christian, what a wonderful surprise to find this video and see you! Hope you are doing well. Thanks very much for posting this.
Hi Alice! So wonderful to hear from you!
oh wow.. i was wondering when it would unfold, but no one in the audience of the livestream i was watching answered my question. now i see it's not a simple answer :-)
High-quality vid, thanks!
excellent vid.
This was very informative and easily understood. Thanks.
