Cosmic time machine

I saw a documtary on Netflix called "Unknown: Cosmic Time Machine" about the James Webb telescope and its intricate planning and construction. It took decades to conceive and construct and even then over 300 single point failures could have detailed and scrubbed the project entirely.

Putting the telescope into orbit about 1 million miles from earth was a Herculean task which took thousands of technical experts and countless hours of effort; all so humankind could peer into the dawn of our universe which is estimated at 13.8 billion years old.

Fascinating and well worth your time.
