Whoop whoop!

So exciting—it’s going to be a long six months.

They only had 1 live camera shot of it and that's when the observer separated from the final stage engine. The commentator said that's the one and only live shot we'll ever get. I'm surprised with all the camera technology we have they don't have several on board the telescope so it can be viewed from home base. We have cameras on all the Mars rovers.

The power coming from that rocket is immense watching the first few seconds. They announced it as a Vulcan 2 rocket...nice name.

The heat shield has been successfully deployed, which is a major part of the complexity and a big milestone!

Woot woot!

I’ve been checking space.com every morning over coffee to see how things are going for JWT. Exciting times!

Humanity's last look at the telescope. HD video from the European Space Agency.

It's exciting to think about what it will deliver once it reaches its "parking" spot.

The deployment has finished, the mirror segments are all in place. All that’s left are some adjustments to the mirror and one last thruster firing to take it to the L2 point. I’m impressed. It’s gone off without a hitch, and all the difficult parts are complete.

Amazing execution by NASA. Congratulations to the team! https://apnews.com/article/space-lau...c38084bd009ce3

La Grange points were actually discovered by Billy Gibbons. He wore a pair of cheap sunglasses to reduce the glare of the sun.

Not many people know that.

I've been following the sequence of events from this site:
https://webb.nasa.gov/content/webbLa...ereIsWebb.html

It's been very exciting to see each step unfold (sorry) and it almost seems anti-climactic now but what an accomplishment!

I'm looking forward to seeing the images. I hope it'll be all that NASA wants it to be.

Best,
PJ

They’re going to insert it into L2 orbit on Monday.

It was actually spherical aberration. Not an alignment at all, but a basic beginners problem. Me and my buddies were grinding our own telescope mirrors at the time and I admit we joined the chorus of derision. Yes, the surface was the finest mirror grinding EVER done. It was very very smooth - which is good. The problem, and again this is a very very common problem, was the parabola was wrong. The shape itself was off.

The thing is, if someone had just stood in front of it and looked critically, they would have seen right away that there was spherical aberration. It is pretty obvious. That was why there was so much derision. It was a dumb mistake.

Fortunately (and yeah having Hubble close enough TO fix was fortunate) the fix worked and we have had these years of amazing Hubble images. Webb is another beast entirely. It is ridiculously complex. Fingers crossed. I am sure things were checked and rechecked a gazillion times. We have waited a long time.

One of the biggest differences are going to be the infrared capabilities. It is going to be the biggest improvement since the IRAS telescope. And that was an eye opener.
