So NASA’s fix for MIRI was literally the old doctor joke: “Doc, it hurts when I do this.” Doctor: “Then don’t do that”
-
As a former student/investigator in the sensor department of the German Aerospace Center (they built the HRSC camera on Mars Express) I highly appreciate your "nerdy" dive-ins like explaining this software tool for astronomers. I think no one would have ever mentioned it except you. That's why I'm always coming back to your channel! Thank you!
-
Thanks for the good news on JWST Christian!
-
This channel continues to be totally awesome. Keep up the fantastic work! đź‘Źđź‘Ź
-
always appreciate the amount of technical detail you include in your videos, you are a very good teacher. thank you for putting in the extra effort and time.
-
Each time something goes "wrong" we learn something more. In this case, about engineering (in it's broadest sense, I'm sure there's a more precise term, I just don't know it.)
-
Wow, this was an impressively good video! I haven't seen topics on space telescopes like JWST explained so thoroughly and with such great visuals as this video exemplifies. Thanks so much!
-
I always stand in awe, when I hear of scientists and engineers managing to fix problems on stuff that million miles away and here I am having to throw away a toaster that stopped working.
-
Please do a video on your former job planning observations on Hubble!
-
Well, the first days are the hardest days, don't you worry anymore! Fantastic to see you again Christian, I was missing my fix of LPA!
-
Yay! đź‘Ť
-
Much safer than me trying to drive in reverse to protect my wind screen from pebbles kicked up by other cars. But a telescope with an "Astroid Defense System" sounds a lot cooler.
-
Imagine being the astronomer who asks for an observation in the MAZ, and ends up putting another massive ding in the mirror.
-
Your Webb explainers are the best in the universe.
-
Excellent summary. Subscribed. đź‘Ť [Edit] I say 'summary' but this was incredibly in-depth and very well explained.
-
The science behind avoiding microimpacts is stunning. Do the adjustment sensors on each of the mirrors have capability of changing the concave structure of each hex mirror too? Just think, there are still people on earth who can't figure out how the Earth is a globe yet.
-
CHRISTIAN!!!! Awesome video!!! See, all the DGA needed was some WD-40 and some duct tape!!! I'm always amazed at how NASA has plans b,c,d, etc. CHEERS!!!!

🎶 "The chances of anything coming from Mars Are a million to one, they said..." 🎶

I know you're a busy man Christian, making these complex videos is quite an achievement. Ultimately I knew you'd give us nothing but the best..Thank you!
-
Excellent Webb coverage as usual. May I wish for an interview with dr Hammel on the Titan observation.
