It's so beautiful to see what a large group of cooperating people, using rational thought, can do. Almost gives one hope for our wiggly little species.
Agreed!
Unbelievable. I have been waiting for 5 years for it to go where it should and that is space. Happy holidays to all and greetings from Montenegro. 🙌
I hope that the discoveries that this telescope brings will help bring awe and wonder to the imaginations of many generations to come and generations to come after them. Here's to a bright future.
I’m pretty sure it is. The grates success in the world by humanity is landing on the moon now it’s time to find what’s in space and travel further and beyond

Awesome! I can't even imagine how many fingernails were chewed to the bone during this launch! For a while now, the launch of the JWST has seemed like stable fusion - always just around the corner, yet here we are!
This brought tears to my eyes! I can't believe it's finally happened, its finally up there!
My sentiment exactly
Thought it was time to watch the launch. Haven't seen one since they were live on every TV back in the '60s. I remember being so excited as a kid, it seemed like there was a whole minute between each second counting down from 10 to 1, Blast Off! I'm 67 now. Those 10 seconds don't take as long as they did back then, but it was still exciting and enjoyable to watch, even with the delays. I was smiling and grinning through it all. Thanks for the coverage and special guests, Christian. I know you were Ready for this for months. 😜
So cool. This is undoubtedly a huge step in human advancement towards understanding the universe and our place in it.
Two years later, I’m still in awe. ❤
This felt incredible, i cannot wait to see the discoveries the JWST will bring. This is the most advanced telescope ever sent to space, and this was the last time and human eyes will ever set eyes on it. Dang it's nerve wrecking.
Yeah it's going to be able to see so far back into the past that it will be able to see its original projected launched date.
They're actually planning on a robot rescue mission, most likely to bring the JWST back to refurbish it.
This is my Christmas gifts 👨🚀🚀📡🔭🥳
Good morning from Oceanside California, Merry Christmas, so glad to be here. It's rainy here in Southern California as well. Thank you for broadcasting the launch.
I am extremely lucky to witness this in my lifetime and everybody born after this second will never be able to say that.
If successfully deployed, I expect the James Webb to raise more questions than it answers. Which is a good thing, imo.
godspeed, may james webb telescope goes far beyond it's expected lifespan.
I’m so so happy , honestly this is the best Christmas present
launching a rocket is difficult but hats off to the engineers and scientist that designed and executed this flight path.
I Had An Amazing Time Witnessing The Launch Together,Thank You So Much For The Live Feed Christian.That Was Just Awesome To A Cpl Medics At Work On Christmas Day❤️🙏🏻✨🌏🔭
Thank you! It finally happened. Merry Christmas!
Congratulations! Nice launch! Can't wait to see the stunning results it will send back to us!
3 very intelligent people streaming all 3 of their computer's audio + whoever is talking.
Thanks for the Livestream Christian I watched yours because you keep it fun and friendly.
Thank you Eric, I'm so glad you watched it with me!
I am watching you from Balochistan
And feeling very very exited about James Webb.
I watched the entire steam, great job! Merry Christmas!
Thanks and Merry Christmas to you as well!
Count down starts @55:07
Waheed Baluch from Baluchistan and I am feeling exited too for James Webb.
Congrates
Sir, you're not the only one who cried. I cried with you too. Now, I want to LIVE to experience Summer of 2022!
The most significant event in the history of humanity to pláče a eye a million miles from earth.
We are the witnesses.
As in Bosun Hicks.
Its All about observation and observing.
Truely amazing.
Godspeed.
This is so emotional, can't wait to see what this amazing telescope will bring to us!
Not quite as long a stream as the Ultima Thule flyby but very nice anyway 🙂
Huge relief when it sailed off into space and deployed its solar panel!
Cristian: Thanks for responding to my L2 orbiting query. Makes sense to me. FYI: I did a little homework, and found that the Earth's penumbra does not quite reach out to L2.
"The length of the umbra cast by a planet from it's parent star can be given by: distance from star / ( ( radius of star / radius of planet ) - 1 ) The length of Earth's umbra therefore varries from about 1.36 million km at perihelion to about 1.4 million km at aphelion. This is just short of the distance of the Earth-Sun Lagrange 2 point (1.5 million km) so satellites posted at this location will generally see a constant annular eclipse of the sun, with the Earth blocking most of it, but not quite al".
So JWST would be in the antumbra then. That would give it some protection but certainly not enough.
Merry Christmas, to all the people involved?..
The sounds of the jungle in contrast with this giant rocket is mesmerizing.
Way to go Webb!!!!
Woohoo Go Webb! Merry Christmas!
Here we go to the future
Can you feel it ?
Oh yess 😎👍
I am quite pleased with this success. Around 30 years of work. Excellent!! Happy Holidays!! (Christian, you seem particularly animated?…)
It's a good start, but don't count your chickens. The unfolding of the mirrors and Sun shield are going to be nerve-wracking to the extreme.
@@dirremoire in 6 months, if all goes well, setup can begin. Of course I’m skeptical. Been married 42 years and find my lovely wife questionable. Hope?
@@your_being_led_by_your_nose uh, I'll put my money on a James Webb successful deployment.
I watched this live when it happened... it still makes me teary when watching it to this day. Absolutely amazing. Can't wait for the pictures and the science to come will blow our minds I'm sure!!!!
Let's go Webb
Super excited. From Missouri
This was an awesome Christmas present for all of humanity! Merry Christmas, my fellow tellurians. Next step is the deployment phase. Still crossing my fingers.
Awesome!!!im too excited for this. Even though im from 🇲🇾🇲🇾🇲🇾!!!!
So exciting this is.
Revolutionary data will come. Marvelous achievement of human intelligence.
I hope the journey goes smoothly.
Can't believe its been 2 years
Lucky, lucky, lucky. Astronomers can put away the razer blades and rope now. LOL 😛
Jeez the upward correction!!
Such a lovely moment in "his story" I mean History!
Merry Christmas 🌲
I hope that we find alien life among the stars. For us to truly be the dominant life form species in the universe, we need to start finding these other alien life so that we can dominate and rule the universe! It is our destiny!
1:03:30 they go down a bit to leverage the Oberth effect (burning at a low point in the orbit gets more effective work from the burn(
Good morning from Florence, Ariz
Gute Reise Webb!!
Hello from sweden
Christian, Fantastic vdeo. Loved every minute. BTW, there is a UA-cam channel called Vox that has a vdeo of two women discussing the design of JWST while they are ASSEMBLING the model. Thought you might want to watch it. The video is titled " Why the James Webb Space Telescope Looks Like That"
AT LONG LAST!!
Lmao at the dude asking you to stfu... some people. Thanks for streaming, Christian!

Let's wait until it's fully deployed with no problems before we get TOO excited.
agreed
They did briefly mentioned about the precautions they did in case of micro meteorites striking the Sun shield or the mirrors. Can you please briefly explain what they meant?
2:35:00 Got it
great job
Dont ever compare this mission to other Nasa’s missions like mars and all that. Because those missions see only planets and this will explore whole universe
Is Hubble going to take a look at Webb to see is everything has deployed ok?
Webb will be too far away to see much of any detail on James Webb. . . . The same reason we can't see the moon landing sites from the earth.
Can’t believe it took off on time
Does opening of solar array soon means...other events time priod or secquence is altererd
Nasa: Hundreds of steps of the deployment have to happen perfectly
Solar Panel: Yeet!
Bet you a pound to a penny this telescope overturns half of what we thought we knew about the universe
What was that space clothing and stuff sore you mentioned again? I can’t remember and I don’t recall where your mention of it is in the vid
THIS IS REALLY AN INCREDIBLE THING. I'M JUST NEVER SURE WHAT VIDEO IS ACTUAL REA AND WHAT IS SIMULATION
.
This is 100% pure animation
@@Name-js5uq based on actual real time telemetry. So, accurate animation ^^
Christian: Great coverage of the launch and your guest's expertise. Muchas gracias. One question about the L2 orbit. Is the orbiting necessary just to stay out of the Earth's shadow in order to recharge it's solar panels? If not, wouldn't it be beneficial to stay within the shadow in order to greatly ease the burden of the heat shields?
Thanks, I'm glad you enjoyed the show! As for sitting on L2, the challenge is that it's really difficulty to reach. That's because you need a lot of fuel to slow down at exactly the right location and even more fuel to stay there. That means more mass which means less telescope. It turns out it's much easier to orbit L2 and deal with the sunshield.
Superb 👍
Thank you France 🇫🇷!!!!!!!!!!!!!!!!!! Paul in ohio

Why wouldn't the James Webb not have a self viewing camera!? Only makes since to add a controllable camera on it. Am I wrong here.
You are
What I don't understand is this launch took place in Peru yet everyone is mentioned except for CONIDA, Peru's space program. Also wasn't President Castillo at the launch? Who in Peru exactly hosted this event?
@@fantomas4935 It would seem like your correct. Can you help explain my confusion. Why was everyone saying it was ready to launch from Peru for the past two weeks? Was it only being stored in Peru? What did Peru have to do with the JWT?
Kourou, not Peru :)
@@LaunchPadAstronomy ohhhh thanks
Up up and away Maine U.S.A.
Does anyone know exactly how they reach speeds over 14,000 mph? Once they reach "space" there is very little oxygen so their thrusters would have to burn an exponential amount of fuel it seems. and then to be able to hit an extremely precision target, it all seems impossibe.
Anddddd go
Why haven’t they used the radioisotope thermoelectric generator as a fuel source ( like on the Mars rovers and the Voyagers spacecrafts )? Wouldn’t it last longer than 5-10 years then?
RTG's can provide power for Voyager type spacecraft and Mars rovers but they can't be used for spacecraft propulsion.
@@erichaynes7502 What about Ion propulsion such as used on the Dawn spacecraft ? Would that have contributed to a longer life span of the telescope’s fuel? Actually because they are too weak. They are used for long term bursts and make a difference over long periods of time….
@@bravo-93 Good question I think Ion propulsion works only for much smaller, lighter spacecraft and even in those cases the propulsion is very, very small. JWST is way too heavy for Ion to work.
When the telescope is in orbit, how long does it take to communicate with it for instructions?
It’ll take a few seconds each way. Not that bad.
L2 is located 1.5 million km from Earth, or 932,000 miles. At the speed of light that's about 5 seconds each way, so 10 seconds round-trip. Each piece of equipment relaying the signal introduces some delay, but the vast majority of the distance is crossed at the speed of light. Now compare this to sending signals to the rovers on Mars: the minimum, average, and maximum distances between the Earth and Mars are 55, 225, and 402 million km respectively. That's 3 minutes minimum, 12.5 minutes average, and 22.3 minutes maximum at the speed of light… each way!
At the end of jwst's life are they going to do a last burn to send it back towards earth?
Unfortunately no it does not have enough fuel to come back to earth but we'll probably send a spacecraft to pick it up someday in the future.

The frog chirps threw me off.
Why has esa no stream lol
Does anyone know why speed seems to have peaked at 9.9km/s around +25 minutes, but by separation a couple minutes later, had already dropped significantly, and as I'm writing this the tracking website has the current cruising speed at 2.6519km/s..? Where did all that speed go?
Earth’s gravity is trying to pull Webb back down. Same reason a ball slows down when you throw it straight up!
Skip to 54:45 for the launch
Merry Christmiss
translator in french sounds like justin trudeau lol at 1:03:40
Gracias por permitir el comentario que debo acer
Back to the frogs.
Technically this telescope could see artificial lights on some planet millions of light years away..
Why couldn’t they launch it from the US?
The Kourou space port is located in French Guyana, just above the equator. When rockets launch from there, they get an extra kick from the rotation of the Earth. To achieve the same velocity from higher latitudes like Cape Canaveral, the rocket would have to make up the difference with extra propellant. Cape Canaveral is at 28.39°N, so the rotational velocity on the surface is ~734 mph; Kourou is at 5.16°N, so the rotational velocity there is ~1,033 mph. So maybe they could have? With such a large payload it may have been cutting it too close. This being the Ariane V's launch site was likely a consideration for the launch provider, along with its great track record of power and reliability.
Following up to Desmond's comments (above or below)...also, launching from an equatorial latitude makes it easier to reach L2 which is "parallel" to, or in-line with, Earth's orbit. The further north (or south) the launch, the more the spacecraft would have to be redirected to arrive at L2 thus requiring more fuel. More fuel is more weight and that should be avoided. By launching from a near-equatorial position, that weight is not needed because it gets the orbital kick from the rotation of the earth.
Finally, Ariane rate of success is impressive enough to be considered, probabilistically, the best card played for the launch.
I'll add that the U.S. paid 90% of the cost to build/operate JWST. The Europeans and Canadians paid the other 10%, including this launch so it does look like the U.S. saved a little money.
U.S. so far has paid 8.8 Billion. Europeans/Canadians have paid a little over 1 Billion USD.
And lastly, at the time of design the Ariane 5 was the rocket with the largest faring; meaning the mirror could fit into Ariane. Plus the telescope was therefore designed around Ariane launches with their vibrations and acceleration.
WE SHOULD USE ALL THE FLAT EARTHERS AS ROCKET FUEL
If you remove your right earpiece you can only listen to the English commentary. Reverse for french.
Woof go find truth♥️
Yeah sure, the cameras aren't _necessary_ for the science but they're necessary for the public interest, which is directly proportional to the amount of money NASA gets, so shame you didn't have them.
