Whenever I see the artwork it reminds me of a popup book.

It is a tremendous acheivement and like everybody who works in the industry I hope the launch goes OK. We all know what it's like to see all our hard work get launched so fingers crossed for those few minutes.

It is origami writ large.

As big as a school bus upon launch, then it unfolds at a Lagrange point.

Indeed.
Weeks of terror they were saying as it sequentially unfolds - too far away for any human to intervene if it goes wrong.
The pictures will be amazing.

Yea, decades of work and several billion dollars at risk - both during the launch and the subsequent weeks of it doing its origami trick.
Best of luck - I'm really hoping they got it all right this time. No going back to fix it like they did Hubble...

Couldn't they simply bundle a programmable robot along for the ride who could operate a screwdriver, a soldering iron, a rag, and an ability to search Google for answers in order to keep any operational glitches under control for the life of the satellite by having the robot work under guidance by his/her superiors at the base station on Earth.

Now there's a commercial idea - Royal Spacecraft Club Orbitside Assist.

Technical complications aside (there are going to be lots of fingers, toes, legs and…:ooh: crossed, mine included) just a reminder about who this James Webb bloke was…It’s not been normal for NASA to name projects after politicians but Webb was probably the politician who did most to get America to the Moon by the end of the 60s…it’s rumoured he certainly knew where the bodies were buried..

James Webb Telescope Launch
 
Nasa sets new date for James Webb space telescope launch

The much-delayed launch of the James Webb space telescope will go ahead on 24 December, Nasa and the company overseeing the launch have confirmed.…

“The James Webb Space Telescope is confirmed for the target launch date of December 24,” tweeted launch company Arianespace, adding that it would go ahead at 12:20 GMT on that day.

Confirming the launch date, Nasa tweeted that the telescope was “encapsulated inside its @Ariane5 rocket fairing”…..

This is quite exciting for me. I’m studying Astronomy and Planetary Science and JWST has the capability to do some great observations into the past state of the Universe, as well as others.

It’ll be a rather nerve wracking experience for a lot of scientists though. Hopefully the launch, journey to its Lagrange point and unfurling will be smooth🤞🏻.

Let’s hope they got the focus correct on this one…. :8

An interesting project, I’m looking forward to hearing how this goes.

National Public Radio featured several astrophysicists discussing the Webb recently:

Fingers crossed, knocking on wood. Ancient best wishes for a successful launch and deployment.

P.S., Thank you mods for moving this thread here from JetBlast. This is probably a more appropriate forum, although many on Jet Blast watch the distant skies.

Nasa to launch newest space telescope on Christmas Day

Dangerously high winds will keep Nasa’s newest space telescope on the ground for at least an extra day, with the launch now targeted for Saturday – Christmas Day – at the earliest.


HOVIS 22nd Dec 2021 09:22

Bet that went down well. 😁

NineEighteen 25th Dec 2021 10:16

Fingers crossed! Still on for a 12:20 UTC launch. Anyone nervous? $10bn worth of technology as well as a LOT of work on this ride 😅.

Launch teams monitor the countdown to the launch of Arianespace’s Ariane 5 rocket carrying NASA’s James Webb Space Telescope, Saturday, Dec. 25, 2021, in the Jupiter Center at the Guiana Space Center in Kourou, French Guiana. The James Webb Space Telescope (sometimes called JWST or Webb) is a large infrared telescope with a 21.3 foot (6.5 meter) primary mirror. The observatory will study every phase of cosmic history—from within our solar system to the most distant observable galaxies in the early universe. Photo Credit: (NASA/Bill Ingalls)

I gather it launched ok. So far so good...

visibility3miles 25th Dec 2021 14:26

Yes. And the solar panels are deployed and providing electricity.

visibility3miles 25th Dec 2021 14:28

Deployment sequence; you can click on each step (at the top of the screen) and see when things are supposed to happen. It’ll take 29 days to get to the L2 point.

Is the mirror image of a photo meant to avoid copyright law for stealing someone else’s photo?

I see it so many times that I can’t imagine any other explanation.

FWIW NASA photos are copyright free, as our tax dollars paid for them, so you can use and abuse them any way you want to.

I am told that there was such a sign on the Webb and that it WAS removed before launch. ;-)

Santa flies in a low earth orbit at night. No collision possible. ;-)

But he probably flies faster than the speed of light, which is impressive.

ORAC 1st Jan 2022 14:47

I thought Santa flew Near-Earth Orbit Extremely Low (NOEL).

Id have to check NASA records for the first NOEL....

A very good video on the design and engineering:

Heat shield now fully deployed and tensioned. JWT now the coolest thing in space!

India Four Two 4th Jan 2022 18:36

BBC report on the heat shield:


There were many who doubted the wisdom of a design that included so many motors, gears, pulleys and cables.

But years of testing on full-scale and sub-scale models paid dividends as controllers first separated the shield's different layers and then tensioned them.
https://www.bbc.com/news/science-environment-59873738

Really good news.

NASA have released a new image that they say demonstrates that JWST's optics are 'working successfully'. The image shows an extremely promising level of detail in the surrounding area of the star they arbitrarily chose to focus on. Which incidentally is 100 times feinter than you'd be able to see with the naked eye from Earth. :O
