Got to see the mirror fully built before going off to CA, was pretty awesome.

I didn't realise it was so big.

Just like the very distinct boob on the third image...jumped right out and bit me

Really? I thought it was bigger
fogdancer
Hope those mirrors don't have issues this time, as Hubble had.
FuzzyX
I am sure that possibility was at least triple independent tested.
TheGhostMinx
Okay, but what about miniature meteorites that strike the mirror?
JustAPileOfCats
Not to be confused with the Robert Webb Telescope, which is aimed squarely at David Mitchell's home.

I was just wondering which carrier will launch this

But can it see why kids love the great taste of Cinnamon Toast Crunch?

Will be one of the greatest achievements in space exploration. Hopefully everything goes well.
Zahnradfee
I'm so thrilled for it. Shame it has been delayed so often.
ChefMIKErowave
How much more improved is this from hubble? obviously a lot but how much?
XAMANDER
A lot. Lol. They should be able to see further back into the universe than ever before and be able to look for signs of life on exoplanets.
ChefMIKErowave
Wow, sheesh, that's awesome...Hopefully it doesn't get delayed again.
buggme
They should put a spoiler on it
gumblemuntz
Will it have bluetooth?
DirkNurple
Seems careless to drag it out on the lawn where a bird could shit on the mirrors.
Zokalwe
Replica.

Man i can't wait for an Ultra Deep Field on this thing. That's what i loved about Hubble the most, the Deep Field and Ultra Deep Field pics.
ManOfKent1967
Imagine arriving at it's destination only to find a dust bunny appearing on the sensor.
KanackyBiznasty
Can't wait!! Good luck and godspeed!
ChanceVLuck
If it stays on the dark side of earth, how does it recharge?
poscduke
I'm assuming it has a reactor?

Its orbit around L2 will only be partially shaded.
Catimodes
Actually, it will stay out of the shadows of both the Earth and Moon all the time. https://jwst.nasa.gov/orbit.html
Zahnradfee
So, dark side of the Earth, but not dark side of the sun. Good to know.
FuzzyX
It will still almost always be in sunlight.
asifwewouldbesomeonebetter
With a really long cord.
Matty3D
Like 6 100ft extension cords should do it.
TheBurritoConfederacy
So expensive, so delayed, dear god please don't let anything on the booster or shade break.
FuzzyX
I am quite sure they already keep duplicate copies of anything important in case JWST does crash into the Atlantic.

Don't speak to god about this. He's probably responsible for the delays because he doesn't want humanity to spy on him.

Boy, I hope they got the mirrors ground to the correct spec this time.

I was privileged enough to take a tour of the clean room where the mirrors were assembled. Amazing the shear size of each piece!
XAMANDER
Awesome!

my brother worked on some of the components for it. he's been sending me pictures of parts of it for a while. First time I really get a /

I want to see what the Pillars of Creation looks like from this telescope.

"space telescope", it's obviously a beacon of insectoid aliens planning an invasion!

Did I read that correctly 933k miles from earth? Why so far away? That like 4 times the distance of the moon
StillNotYouTube
It's the L2 point...they like that for some reason.
grandmaspants
It's at lagrange point 2 (out of 5) which is a natural point where the gravity is such that the orbit is relatively stable.
Munchman347
Aren't the Lagrange points cluttered with rubble? Or is that a fairly clear spot?...
Ajax26
L4 and L5 are because their orbits are stable. So they collect space debris naturally. L1, L2, and L3 are mostly stable but require some 1)
Ajax26
2) additional means to keep the orbit from decaying (i.e. rockets). Because of this fact L1, L2, and L3 don't collect space debris.

2021...... To be continued...
Cranbananarama
Good time to work on a sea lab at least.
Roqinn
Again and again and again. They have extended it a few times and have gone WAY over budget! Be lucky if its not canceled.
FuzzyX
Far too late to cancel it now at the final assembly and testing stage. You can't be pleased though at the huge overspend & long delays.
dionweston360
Not possible.
XAMANDER
No way will they cancel the mission. They've already spent over 10 billion on it and are getting close to the finish line.
goosebusters
While originally quoting 1 billion... Then they acted shocked when they had a lot of programs axed over the years
Zahnradfee
Additionally: It's too awesome to be cancelled. A whole generation of nerds will be dissappointed. JWST or we riot!
dionweston360
Yes apparently they've seen the finish line with the telescope.

delpharseven
Plagued by budget overruns (~100%) and missed schedules (3 years and counting). Sure hope it works.
IChangedMyNameToBeAnonymous
Ask the military, they've got plenty to spare.
WhoYouGonnaCallGhostNappa
That's what happens when you have to invent the technology for the thing you are trying to build
MechanusIncarnate
govt projects are always like that. NASA has a good track record though.
ILogInToUpvote
I launched one of these in Kerbal Space Program, it went well. I'm sure Nasa can do the same.
FuzzyX
The original estimate was $1.6b budget & 2011 launch. $5b at start of construction. $10b now & 2021 launch.
merdock379
A pittance for what it is and will do.
thjoth
Could have spent that $10B on any number of other space missions that would have advanced us farther as a species, though.
maito
Disagree with you yet upvoted since you still have a valid point and things like this should be open to debate.
MegaDeuce
It's NASA. Are they going to be in budget? No. Is it going to be on time? No. But they always work it out eventually.
Manzoman666
But Northrop Grumman is building it though.
Hendlton
Was the Apollo mission way over budget and way later than expected?
MegaDeuce
No but that's old NASA, doesn't count.
nanyatenyaa
The Apollo mission was a completely different set of circumstances for the country as a whole.
Letardic
At the cost of generational tax burdens....yay.
spetcnaz
Did you protest the new tax cuts and the unbelievable Pentagon budget?
arkuamore
If you want generational tax burdens check out the senate budget report of those new tax cuts
irishScott
All of NASA is less than 1% of the federal Budget. Look to multiple unnecessary wars for your tax burdens

Looking forward to this. I'm still rooting for the hubble though. I hope they can fix it
bondance
I heard they fixed it by turning it off and turning it on again. Is that wrong? Was I pranked?
TheSlowBladePenetratesTheShield
Hubble is fine: https://www.nasa.gov/content/latest-hubble-news/
FerrousBuehler
Hell yeah! Haven't checked up on it for a few months. Thanks
sentx
? I thought it was still operating with a planned EOL around 2035
AstroExplained
Hubble should be fine at least for another 5 years or so. It's down to 3 gyros. If 1 fails, they'll operate with 1 active and 1 reserve.
AstroExplained
However Chandra did lose a gyro and Spitzer now has a final deathdate.
Acronymicon
I’ve never had a gyro, are they any good?
equityforpunks
Pretty sure Hubble is running fine again. It was Kepler that was recently retired.
FuzzyX
And don't forget Dawn is now out of fuel, and out of contact, but as planned now set to orbit Ceres for hundreds of years.
FerrousBuehler
Hubble lost a couple more gyroscopes and is down to 1. I think nasa said they can't get any more deep, long exposures
MoreTan
But your mom can
Mikehusker
HaunsTBUP
So happy they finally found out what was causing the gyroscope failures
FuzzyX
That gyroscope had an overspin problem where they suspected a blockage so had Hubble do manoeuvres to clear blockage & it worked.
FerrousBuehler
Nm, article came out a couple weeks ago stating they got it back
goosebusters
They turned it off, and on again
goosebusters
I'm not kidding
vortexwake
Well actually what worked was wiggling it which is the equivalent of just hitting it to make it work
