Thanks for the links, schnoz.
I remember when Hubble was launched and they found out it was blind. Or essentially so. And they came up with this daring spacewalk via the shuttle to correct its vision. And everyone who cared (including me) felt that the chances of success were minimal. I mean, if they couldn't get it right in the first place, how did they know that their efforts to correct the vision of the telescope would work. But it did. And wow.
I'm old enough that I may or may not ever get to see the pictures from the Webb telescope. I sure hope so, but I'm not in charge. But even if I never get to see the fantastic stuff that it is sure to find, I'm pretty satisfied with all the discoveries and confirmations made by Hubble. It beats the crap out of when I was a kid and they weren't even sure if it was possible to make a rocket powerful enough to put stuff in orbit. They knew it was theoretically possible. They just didn't know if it could actually be done.
I've lived in exciting times. Too many guns, but otherwise, pretty darned exciting.
