   JWST's primary mirror is made up of 18 hexagonal, gold-coated segments. A new blog post is out today from the team that keeps the mirror segments perfectly aligned so that they function as one big mirror.

   So far, everything is going great. The overall performance of the telescope is far better than expected, and the alignment needs fewer corrections than expected.
