The Webb Space Telescope has transormned into its final form. Now it is on its way to Lagrange point 2.
JWST has already completed about 80% of the way.

Just a quick reminder: the main goal of James Webb Space Telescope is discovering the birth of stars and galaxies, looking for planets to live on. This is the greatest telescope we have ever created.
That's quite a statement in behalf of a telescope that's still half a year away from first light.

JWST has started the alignment of its 18 golden hexagons. When the setting finishes, the mirrors will be workning as a single focusing instrument.
Whole procedure will take 3 months.
By the way, JWST has already completed 84% of its way to Lagrange point 2. I've also found a cool explanation of JWST by Tyson, highly recommend you to watch it.

  • Half an inch, half an inch,
    Half an inch onward,
    All into the valley of L2
    Rode the JWST.

Mirror Segment Deployment Tracker

<<This image tracks the progress of the individual primary mirror segments (A,B,C) and the secondary (SM) mirror as they move upward 12.5mm from their stowed launch position to a deployed state where they are ready for the mirror alignment process. The mirrors move in very small increments over the course of ~10 days to complete their deployment. They move approximately 1mm per day each. For more detail on this process read this blog entry. Each primary mirror segment has an ID which consists of a letter (A,B,C) followed by a number. The letter denotes one of 3 different 'prescriptions' for each group of primary mirror segments. NOTE: Segment A3 and A6 are being moved separately at the end of the process because their position sensors are read out in a different way.>>
