Me too.  Just now they're warbling about stuff anyone who's interested will already know.

I’ll be having a look in shortly. Son-in-law bought a telescope for Ms Beardy the elder which made her very happy. I’m a little jealous, especially as she lives on the edge of Dartmoor which is a protected night sky.

Switched off the stream when some nasa administrator started some sort of christian sermon...

This is space science, why are they bringing Christianity into it?

Anyway, was a good launch!

I think Nancy-Grace-Roman telescope is the next up, which will be in no more than 6 years.

The roast duck was going critical and I was deep-frying prawns when the count hit zero, so I missed it.

The next dodgy moment is when they start to unfold it. I suspect there we’ll be a fair few fingers crossed when they press that button.

I think I've inspired both my children and our three nephews by the wonders of the universe and the enormity and significance of JWST with the result that we all sat and watched it lift off.

Little Miss hatler, who up to now hasn't been too enamoured of things scientific is blown away by the whole enterprise and is sending links to the lift off to her mates.

There's hope for the future !!

Did I read that there are 237 single points of failure in getting this thing up and running ?

This is good: Deployment sequence  https://www.youtube.com/watch?v=RzGLKQ7_KZQ&t=107s

Does show that there is a lot that still needs to go well...

JWST orbit lagrange points info is interesting...  https://webb.nasa.gov/content/about/orbit.html

307 single points if failure, out of a total of 344 moving parts.

Between days three and seven, Webb will deploy the parts of its sunshield, raise the tower assembly and deploy the momentum flap. Day 10 might be the most nail-biting, as Webb hoists its secondary mirror into position. Heidi Hammel, a scientist on the mission, said:
For me, personally, that’s the scariest part of the whole deployment sequence, the secondary mirror … If we don’t have a secondary mirror, we don’t get any light from space into our cameras and spectrographs. There’s nothing.

The secondary mirror deployment mechanism looks as if it uses quite robust hinges & joints, so I wouldn't worry too much.  It's the sunshade that looks like the real nail-biter, given that an earlier test tore one.

Yep, that's the thing that's scaring me.
