btw PBS Nova has an awesome episode on JWST, how hard it was to get built and how it almost didn't get built because massively over budget ($10 Billion!)

This is kind of a "part 2" follow-up after it was launched and "first light"

- jamiek88 3y agoOoooh thanks for this! I always forget about Nova then like almost all of their programs, think I should watch more then promptly forget!
- dylan604 3y agoI started watching the Nova episode. I didn't realize the timing of the testing done in Houston during hurricane Harvey. As if the stress on getting JWST built wasn't enough, but now it's in the path of a massive hurricane that parked itself over the area dropping 40"+ of rain. Edit: just to add that I found the segment on the alignment process of the 18 mirrors an interesting puzzle. Once you've found all of the pieces, you still have to decide what mirror each part of image represents. I've aligned my telescope mirror's primary/secondary mirrors on terra firma, but you at least have a bit of a feel for how much you're adjusting. Doing that remotely from 1M miles away, just makes it that much cooler
