The Webb Telescope Journey to Space Part 5: Spacecraft Fueling
HTML-код
- Опубликовано: 5 дек 2021
- Ahead of launch later this month, ground teams have successfully completed the delicate operation of loading the James Webb Space Telescope with the propellant it will use to steer itself while in space. Learn more here: blogs.nasa.gov/webb/2021/12/0...
This video shows preparation for fueling. Now that fueling is complete, the Webb Telescope's next step is moving to the vehicle assembly building, where it will be placed atop the Ariane 5 rocket. The Webb Telescope journey to space continues…

In less than a year we’ll be using the line “before Webb we used to believe that....”.
👍
🤔
It's just such a magnificent device. It's beautiful.
This is important for the world. Who on this blue/green/brown rock doesn't want to know what's "out there." Good luck Webb telescope!
I literally hold my breath when I watch these videos cause I’m so excited and anxious in the same time for everything to go well 😄❤️
Once in a generation telescope. If all goes well the greatest technical achievement of mankind ever
I wish they had shown some of the actual fueling operations.
When this launches successfully and deploys successfully and sends home that first image, that'll be the best Christmas and New Year present ever!
I doubt we will have first images this year.
@@petrzawierucha7006 I agree - but I don't mind the gift coming a few weeks late!
What is gonna be the first 'target' of WEBB? Does anybody here have clue yet? If so, would be cool to know.. thx.🤗💫
@@mathiasp. we should have a poll to find out what people think:
1) the approaching Vogon constructor fleet
2) Proxima 1b
3) the rings around Uranus
4) the Hubble space telescope
5) Earth (to prove once and for all what shape it is)
6) something else
@@Fanny-Fanny 7) or any kind of planet at all?
I have not discovered any kind of "comming up - fitst sight masterplan" anywhere at the official sites... did you?😉✌
Oh man, I'm so excited and scared at the same time, a new era is about to begin.
besides the Large Hadron Collider the James Webb telescope May quite possibly be single most impressive and complex piece of technology mankind has ever created.... 😲😲
Let's hope it accomplishes more than the LHC, which so far has done nothing but confirm the Higgs boson.
Lol "Only" proved the existence of the Higgs Boson...are you being sarcastic?!!
@@smittenthekitteninmittens2679 No. Tell me exactly what it discovered other than the Higgs? Supersymetrical particles? Evidence for string theory? Dark matter particles? Any of the many things predicted by the scientists who justified the enormous expense with their false predictions, who now want to spend even more for a larger one, to again try to convince us that null results add to our knowledge? String theory is dead. Supersymetry is dead. The money should be spent on better things.
@@JCO2002 killing string theory was the best thing it ever did, to be fair
Oh god, nail-biting and so exciting. Wondering... what might it see?? 😳🤔 I wish my Dad could see this.
can't wait to us to collectively stop holding our breath later this month
Deployment in space will take a month, I'm more worried about that part.
Best christmas gift I ever received!
We are all waiting for the launch of the telescope into space! 🚀
Lashgo JWST, been waiting 20 years for this, good luck
Bravo za Zemljane! 🇸🇮❤️❤️❤️
I'm so anxious about this and very excited, I hope in the name of God that everything goes to plan so we can get richer about the knowledge of our universe. It gives me chills and makes me feel proud of humanity, using our intelligence and all we've learned in the past for good and not for bad.
In the name of what now? :)
Which god? And after you answer, for example, "Zeus" ask yourself, how do you know? And if you answer "I just have faith" then know, "faith" is the "excuse" people give if they don't have good reasons to believe ;)
@@Tolkoum shut up, ain’t gonna waste time with you kid. If you don’t believed in God just keep your mouth shut, ain’t no body’s problem, as it ain’t no body’s problem what I believe.
@@discoverymoi Ohhh, how cute, a very nice example of your intellectual level. LOL " shut up" "kid" yes boy cry, show to everybody who "those believers" are, and the level of aggression they experience when they have no arguments about their stupid beliefs... Hahaha
@@Tolkoum lol you’re definitely a kid, “level of aggression” and yeah let everybody see.
Such great moment in human history. And we get to live it through this vids and updates.
1990's didn't provide us any info and moment to live with Hubble when it was launched.
It's going to be great to be oqrt of history with JWST launch and deployment phase.
Closerer and closerer
That's the revolution. I am so excited 🔥❤️
Not usually interested in space launches but the images that Hubble generates are incredible and I’m looking forward to these also. Thanks for all the hard work
Awesome can't wait to see it go up
At this point it's not all science anymore, it's an emotion now.
Here we go! 🚀
im soo anxious cannot wait aiseeee
awesome cant wait :)
I am so exited to see the first images of space by James Webb space telescope.
🤞🏾Spring '22 🤞🏾
@@theendofanerror4173 June maybe ? anyways somewhere between April and July.
Go NASA go...Go ESA go...eagerly waiting for success....from Goa...
What a deal. A telescope that just cost a $1.00. (Per year since the "Big Bang").
😂😂
money is nothing. the revelations that this will bring are priceless. this is a leap for humanity.
And who the heck knows? Webb could end up revising that whole timescale.
And most likely, it will reveal the fallacy of the big bang theory.
@@blujay9191 we can already see up to 300k year after the big bangt
I’m so excited
Can't wait 😄
I'm crying right now.
It’s the coolest video of the Webb telescope so far :) GO WEBB GO!
Amazing
Buen trabajo!!
ESPETACULAR INCRÍVEL
Nice music, but they should put heartbeat music instead.
The JWST is becoming alive, its being born right now. Its nail biting situation right now.
jetpack joyride vibes
Don't forget to carry the 1 when calculating launch parameters!
Great 👌👍👋
Psyched!
Is this before or after they exploded the adapter ring?
Waiting with lot of anxiety
Please make sure all parts are installed correctly and the software is configured with the proper codes.
I eagerly await the first time I say "Holy shit!!"
look 1:10 attention
Repuestas al universo. Estelar
👍👍👍
Judging from the skiff suits, it's powered by hypergolics then?
😭😭😍😍
Only 13 days left 😄😄
I'm a nervous wreck already.
Where is Part 6: Spacecraft Loading in the VAB ?? I would like to see that process. Don't tell me they didn't record it!
They didn't.
@@oogway5472 oh boy I can already see the conspiracy theorists going rapid fire mode. "they did not record the loading procedure so its obviously fake" lol oh god
I echo the comments below I'm so nervous and excited for the launch and to get our first images please please please no more delays!!! I mean were you not supposed to launch in 2007?? Wow now that really is a big delay..but it will be worth the wait...after Jwst gets up there you should really bring down Hubble to be put in a museum..it doesn't deserve to just be left eventually to a decaying orbit where it will burn up in the atmosphere..after all it has shown us it deserves more...is there a petition I can sign??...anyways the world is waiting with bated breath God speed xx
I wish there was more info and video of the fueling. How toxic is it? How much fuel is there?
42 gallons (159 litres) of hydrazine and 21 gallons (79.5 litres) of dinitrogen tetroxide oxidiser. Both highly toxic. This info from their Instagram account.
According to the James Webb Space Telescope Initial Mid-Course Correction Monte Carlo Implementation using Task Parallelism, J. Petersen et al.
"Two sets of thrusters comprise the observatory’s propulsion system. The first is a set of Secondary Combustion Augmented Thrusters (SCATs) that are the main thrusters for the MCC maneuvers. The SCATs are bi-propellant thrusters and draw from two separate tanks for a hypergolic reaction. Two pairs of SCATs exist: one for MCC-1a and -1b, and one for MCC-2. The MCC-2 SCAT is also employed in station keeping throughout the life of the mission. Two pairs are required because the center of mass of the observatory changes between MCC-1b and MCC-2 because of the sun shield deployment; the thrust vector from a SCAT is directed through the center of mass at the time of that maneuver. Each pair is composed of a primary and a redundant thruster (the respective thrusters are coupled to the prime and redundant flight systems; only one system is on at a time). SCAT 1 and 2 are the primary and redundant pair for MCC-1a/b while SCAT 3 and 4 are the primary and redundant pair for MCC-2 and stationkeeping. For a given maneuver only one SCAT is on throughout that maneuver. The second set of thrusters is composed of eight Dual Thruster Modules (DTMs), each comprising of a primary and redundant Monopropellant Rocket Engine, 1 lbf, (MRE-1) thruster. A schematic of the propulsion system appears in Fig. 3. The MRE-1s consume hydrazine fuel only (and no oxidizer) from the same tank as the SCATs. The MRE-1s are subdivided into two sets: MRE-1s 1 through 4, which are directed generally along the observatory J3 axis for pitch and roll control, and MRE-1s 5 through 8, which are directed radially about the J3 axis for yaw control [3]. A picture of the spacecraft bus with the body J frame and orientation of the SCATs relative to the J frame appears in Fig. 4. Together, the MRE-1s on-pulse throughout a maneuver to control the attitude. Because of the location and alignment of MRE-1s 1 through 4, any firings to control pitch and roll during a maneuver may result in an additional ΔV to the MCC maneuver. Therefore, thrust contributions from the MRE-1s must be included in the design of the MCC maneuver."
iam waiting webb launch into space and see the new secret of universe
The building of JWST took so long that in the mean time a 9-meter diameter rocket was built (Starship), rendering the complicated mirror folding unnecessary.
Song?
oh boy i sure hope that the point that it launches in dec 22, is also the point of no return
Can't wait to see this launch in five or six years.
@ 1:09 it looked a bit out of control 🤔....
Yep, looked a bit risky for how careful they have been with the program.
Clearly they are not the ones that designed all the systems on that vehicle. I would be handling that thing better than my new born daughter.
@@ZeroSpawn
NASA and LM engineer are there also. And they used the same machine in the US. Not impossible we saw them on the video
Hmmm. How long before it runs out of fuel ??
Apparently it's operational life is 5 years.
@@MelonHead887 - Wow, that's really short. Hubble has been going for decades.
Today 07/12/21 🕉️🇮🇳
This telescope has been delayed more than GnR's "Chinese Democracy." It hope it's better than that album.
omg omg omg OMG OMG OMG
Thank you God for JWST
Uuhhmmm, god didn’t build it.
Man did lol
I hope it works. If it fails no one will be held accountable.
With the amount of money already invested in this project, there would certainly be accountability if it fails... but I am sure they have already taken it into consideration. But this is how you advance; by taking risks (but doing whatever you can to minimize then).
Just launch the damm thing dammit.
why not 4k. this is a moment for the history books. it should be recorded as such
As if this telescope is not going to fly ...
Stop touching it, something might happen again
Can we rename it to "Henrietta Leavitt Telescope" please? 😊
NO!!!
Oh Lord, please don't F this up.
I find myself saying the same despite being agnostic.
first
1:08 Are they pulling on the entire assembly... *BY HAND??!!* They have one of the most sophisticated (and fragile) robotic systems ever made and they can't use a motorized base with omnindirectional wheels to move it around in a secure way? This is outrageous!! 😡
engines, wheels, gears, computers would need testing, human hands only training. they're safe
Sometimes simple is better.
@@orzeleo I guess so... but they could have created that motorized base in advance. Compared to the rest of the project, it is a fairly simple task. And it is not like they didn't have enough time to prepare it.
This support move on a thin air layer
@@SystemBD i think about this again and i wthink it is motorized imo
Amazing job, over a decade late and 9 billion dollars over budget!
