Here’s how the James Webb Space Telescope is aligning its mirrors in deep space

The James Webb Space Telescope continues to fine-tune its mirrors to ultimately peer into the deep and distant universe.

The telescope launched Dec. 25 with the 18 hexagonal segments of its primary mirror and its secondary mirror folded up and stowed so that the components would survive the rigors of liftoff. Now, the telescope is close to reaching its way to its deep-space destination and is starting to move those mirror segments into alignment.
