This project is so exciting, and still on Terra Firma. Having imaged with a Newtonian, I understand the need for perfect optical alignment!!
#ICYMI, here's how the alignment of @NASAWebb's mirrors is fine-tuned to produce sharp, focused images. #JWST https://go.nasa.gov/2zTS7mg pic.twitter.com/In50t6DeJo

How are the mirrors going to be protected from abrasions caused by micrometeorites?

Micrometeoroids will only have negligible effect on our beryllium mirrors and not affect their performance. Read more: https://jwst.nasa.gov/faq.html#micro
