Hey there, cakeday comrade. We are in sync.

Except. I'm way too disorganized to set up a giveaway for mine. As usual I will blast out a few here and there as public lvl3+ with no fixed pattern. Meanwhile, I am technically "working" atm.

Happy next decade, too!

Happy Factory Day :D

Also, Webb is such a brilliant piece of machinery. I was following when engineers were deploying the sun shield. They had to "unfold" five tennis-court-size layers, made from polymer thin like a trash bag (covered in 0.0001mm thick aluminum layer for sun reflection).

It needs a passive method to cool itself (the sun shield), otherwise it would not take any photos. It basically "sees" temperature (infrared radiation), so mirrors and detectors must be extremely cold all the time to work properly.
Hubble telescope sees UV, visible and near-infrared, so it can bask in the full sun just fine.

The accuracy of a telescope's mirror manufacturing is also amazing. Usually it has to be better than 1/4 of the wavelength you want to observe (Webb: minimal wavelength 600nm -> accuracy of the mirror has to be better than 150nm over all of its surface).
