If any of the James Webb team are here, Congratulations! A phenomenal achievement.

So excited to see first images and read about all the discoveries you are going to make. Exciting times!

My daughters (7yo) class have been talking about it, she keeps coming home from school excited to tell me about the latest update on its journey. I love the fact we have these exciting things happening in space science to experience together.

I'm a little embarrassed to say this and I don't know exactly what I pictured in my head, but I had no idea these telescopes were so big[1].

I guess I never saw one pictured next to a human. I've only seen pictures of satellites being worked on so I expected something more human sized? It seems so stupid now, especially since earth telescopes are huge.

It's funny how the excellent job of the French Ariane launcher is nowhere to be seen in this (and others) article.

Ars Technica did a well-written story on it recently -- https://arstechnica.com/science/2022/01/all-hail-the-ariane-...

That is an interesting observation I never considered. If it were a SpaceX rocket, it would have been mentioned once per paragraph, minimum.

This was an absurdly teeth-clenching deployment.

And no back-up, even if the Ariane launch failed. No back-up.

Congrats to everyone across the board for getting this amazing telescope right where it needs to be.

Now all we need is the mirror alignment and we're in for some seriously incredible science.

If you go to https://jwst.nasa.gov/content/webbLaunch/whereIsWebb.html then there are repeated statements about how the rocket did such a good accurate job launching Webb onto its intended trajectory that the telescope hasn't had to use as much of its own rocket fuel as they expected, so the fuel is now expected to last 20 years instead of 10.
