Avis à la une
The early development and various designs was glossed over by a guy petting his dog going through wrinkled papers on the dining-room table. Should have been more about why it uses infrared light and red-shifting of distant galaxies, why the Arianespace base in in south america. And so on.
The worst parts were the segments with the airheaded valley girl types on the phone screens jumping up and down saying "Ohmygod" "yay" etc. Gag me.........
Couple of comments: this documentary does a great job explaining some of te background as to what it is the James Webb Space Telescope actually does which its predecessor didn't do. Much attention is given to the 344 "single-point failures" which the 10,000 men and women who worked on the Webb for several decades, must avoid, an almost Herculean challenge. The big pay-off comes in the last 10-15 minutes when we get the spectacular photos which the Webb is now collecting, along with a treasure-trove of related data. One of the photo's shows a galaxy "being born" 13.2 billion years ago (yes, not all that long after the big bang). It also made me think how planet Earth has been fundamentally ravaged with in just the last 250 years or so (since the Industrial Revolution). This does not bode well for the future of humankind...Meanwhile, enjoy this every entertaining AND educational documentary. Can be viewed by anyone from ages 7 to 77.
"Unknown: Cosmic Time Machine" started streaming on Netflix a few days ago. If you have any interest in space or in human explorations, I'd readily suggest you check this out, and draw your own conclusion.
What is red shifting and tangible explanations on why the JWST is needed over the Hubble.
The groundbreaking use of beryllium for the mirrors and why the element was selected for its unusual properties at cryogenic temperatures.
The cryo coolers and how their novel design allows it to cool the instruments down to near absolute zero.
The damaged mirror and how the JWST is able to overcome it.
The unusual approach of physically deforming the mirror to focus the image.
Etc etc.... Could have been great but instead they took a story about one of the greatest scientific achievements in human history and chose to dumb it down to nearly worthless drivel.
There was only one character/astrophysicist that was really. Too much gibberish for me I fast forward her parts. I want to know the educational and the story and people behind the scenes.
