I quote: "One particular challenge is the phase distortion experienced by the incoming light that travels cosmic distances breaking through the intergalactic space, and dust clouds as it approaches the atmosphere."

There is no such thing. Astronomers use deformable mirrors to compensate for _atmospheric_ disturbances (pockets of air at different temperature which make stars "twinkle"), in real time.

JWT is in a vacuum and it will only be necessary to align its various parts against each other.
