I'm gonna laff when the rocket taking it to space blows up

Ariane 5 is pretty reliable, don't get your hopes up

James Webb? No, we need to think bigger

Well at least people will only have to wait two weeks to know if it unfolded right. The Galileo Jupiter mission was crippled when an antenna did not unfold right. It was blamed on it the launch being delayed and it being in storage for years.

>>12735606
For the transport to Guyana, will they contract the Royal Navy to sweep the sea clear of pirates? Or being so close to the Spanish Main will they leave it to the Armada?

>>12735625
And if it fails to deploy as expected?

>JWT

Test.

Gravitational lensing telescopes make me fucking HARD

>>12735606
If it doesn't blow up on launch, just as the mirror is unfolded it will be struck by a space rock and be completely destroyed.

>tfw the average american's reaction will be; "it's fake" and/or "can they see the face of god?" and/or "think of the amount of gibs ah cud have had but dey waste it on this an ah gets nuffin"
Good luck in your former-ussa.

They tested impacts on Beryllium mirrors, only a small fraction of the mirror would be degraded. Because the mirror is segmented even a larger collision would not destroy the whole thing, it would still function fine without a segment.

>>12737826
Okay maybe the thrusters will fail and it will just whiz by the lagrange point. They just yeeted a 10 billion dollar piece of junk into outer space. That would be funny.

>>12735606
Anyone who knows something about this piece of tech please tell me in at least 3 sentences what will this do . i know it will see farther and in the same time "more" back in time but yeah im a dumdum so please .

JWST is largely driven by the goal of detecting and characterising the earliest galaxies, to understand the processes of structure formation and galaxy evolution. More distant galaxies have their light redshifted to longer wavelengths, due to the expansion of the universe. The most distant galaxies currently known are so redshifted that they are barely detected by current instruments. JWST is infrared optimised so it can study these distant galaxies and more distant ones. The other issue is that current observations of these galaxies are basically limited to how bright they are, very little is known. JWST will be able to do spectroscopy to study these objects in much greater detail, like their history of star formation, their chemical abundances and many other parameters. JWST is not just for galaxies, it will study lots of things. It will be very good at studying the atmospheres of exoplanets. It will shed light on how early galaxies ionised the matter between galaxies, the last major change in the history of the universe.

Pictures that will make Hubble look gay.
See back near the beginning of time.
See planets with life by observing their atmospheres

>>12737815
Thats nothing I (a British man in Northern Ireland) was excited about the UAE and Chinese probes as they entered Mars orbit a few weeks ago and my coworker said ‘Do you think its a good time for that, Don’t you think that money should have gone to the NHS?’

>>12740445
this is infuriating

Aren't there a fuckton of rocks at L2 because of its stability?

>>12735606
If dubs it blows up

>>12737815
You realize most people posting that shit are from our government, right? You realize they're doing the same thing in your country, right?

>>12737824
>Peoplemsay this even as most money goes to pointless BS pork and military spending that hasn’t even produced powersuits yet despite literal trillions of dollars for the military

>>12735625
It won't but telescope breaking down within a year is likely.

>>12735606
I can't wait for all the news of "Planet x may have phosphine and planet y maybe has methane which may indicate life or maybe rocks are doing something or other, how are we supposed to know, we are untold billions of miles away, but hey you can tell your friends over a beer that you read this headline!"

>>12735625
>I'm gonna laff when the rocket taking it to space blows up
No, I want the rocket to work perfectly. I want the device to fail and NASA to have no one but themselves to blame.

>>12742814
I can't wait for it to discover literally anything noteworthy because apparently the thought of this telescope succeeding at all makes /sci/ upset

>>12743232
The angst is at how much this project has been a management fuckup. Any hope that it fails is a desire for its failure to create an actual cultural change that will prevent this type of waste from happening again. If it succeeds, everyone will forget what a fuck up it has been and worse, everyone involved will be showered with bonuses and promotions so they can go on to fuck up even more projects.
In the short term, a successful launch and deployment is a win for astronomy and many related fields of science. In the long term, it justifies the glacial pace and gross waste of resources that could have produced much better results had they been managed better.

>>12735693
It takes a long time to get to the solar gravitational lense. A solar gravitational lense telescope can not be repointed practically

8 months till launch.
Then 18 years to fix all the deployment issues

>>12738457
It's an infrared telescope because it is going to look at stuff that is so fucking far away it's redshifted out of the visible spectrum.

>>12743843
They can't fix anything at L2 orbit. This is a one shot deal, hence the anality of the people testing it

>>12735606
Some are VERY optimistic, and is planning pic related even before this one leaves the clean room.

>>12740735
No. L2 (like L1 and L3) are not that stable, more like saddle points; any longitudinal perturbation will have a positive feedback. Locating something in L2 requires regular repositioning.
You might think of L4 and L5.

>>12735693
This gave the me biggest nerdgasm I've had in a long time. HOLY FUCK.

>infrared telescope
wow its fucking nothing

>>12746625
Did you know that Hubble's most infamous pictures are near infrared?
I doubt you could even tell the difference because your concept of what infrared is, is probably based off the predator movie

>>12735751
Didn't they know about WD-40?

NASA haters are literally 0-for-life, NASA is the great institution to ever exist on planet earth.

>>12744975
Why not invest the resources on being able to fix things at L2 orbit? That seems like it'll have a higher ROI.

>>12735606
where can I find the Vegas odds this thing blows up on the launch pad - its a sure thing.

>>12747381
Sure is.

>>12748381
Vegas probably won't let you gamble on such a thing. You'll need to go with a British bookie for this one.

Falcon Heavy is getting bigger fairings for Gateway. JWST should be launched by FHeavy from American soil.

>>12748374
Starship

>>12748533

>>12748533
>Falcon Heavy is getting bigger fairings for Gateway.
Not soon enough. And it would have to fly several times with this new fairing before launching JWST. A5's fairings have been testing modifications to reduce risk. It may also require vertical integration.

>>12746454
Right, thanks.

>>12748397
Have you read the latest ESA opening? They want to consider "diversity" when hiring astronauts now. This madness was created by the USA, which should be fucking nuked

>>12735625
god rockets are such shit. bet it happens. seems like they could invent a way of getting into space that doesn't involve riding an explosion.

>>12749407
If the US jumped off a bridge, would Europe do it too?

>>12743657
Not him but youre reaching man. Muh i hope ITER fails because of the poor resource and tome management!
At least i hope you are. If you really feels this way, im sorry bro, that sucks.
