Just ask Kirk, I think it’s rather cold “out in space”

It took close to 20 years, but glad to see things going well so far.

Physics/engineering at its finest. However, I keep thinking of the first track of the second Animusic vidio and have to come to the conclusion that the scope designers copied that spaceship. Go look.... ;-)

Webb’s optics team will be ready to begin meticulously aligning the telescope’s 18 primary mirror segments to work together as a single mirror surface. NASA is targeting star HD84406 to begin this process. It will be the first object NIRCam sees when photons of light hit the instrument’s powered-on detectors.

It’s the telescope’s version of an eye exam. “Is this lens more clear, or is this lens more clear?”

That’s what happens when you keep changing the specs on optics

All right! I consulted briefly on the program when some issues came up.

Elon goes up and back, with private enterprise on a budget
and the “Science” world is . . . ho hum . . .meh . . .
Global Warming Cretins at NASA spend Zillions and can turn the lights on.
and we are supposed to be impressed?

Very cool.
... and getting colder. There are still a few things they cannot fire up until the main cooling system hits a certain temp.
Then the fun really begins.

I hope Perkin Elmer didn’t grind the mirrors this time.

No, thank God.
Tinsley Laboratories, Richmond, California did the grinding and polishing.

Cooling the instrument and cameras are critical. Even amateur astronomers strive to cool their cameras/sensors down in an effort to reduce noise. I don't have a dedicated CCD camera and at this point I only use DSLR consumer grade cameras which can be a bit difficult to keep cool, but there are various methods, modifications and techniques to help keep things cool.
I recently obtained this image of the M42 Nebula, using some of those basic techniques.
