Yeah the JWST will go down as one of the most important pieces of scientific hardware ever created. She and all the NASA/ESA/CSA scientists who created it deserve all the medals. IIRC it was ESA's most viewed launch to date, I sure remember stressing tf out haha.
Given that they had a test failure that would have led to mission failure like 2 weeks before launch and said "yeah we figured it out, we're good" and launched the fucker, a little nail biting was justified.
Oh god yeah I remember. Legit $10Bn "we only got one of these" moment. They made the right call using the most reliable rocket and an equatorial launch too.
