    While aptly named, when I hear that name, I think of another James that inspired a lot of my generation.

    We could isolate Russia totally from the world and maybe they could apply for membership after 2000 years.

    Very interesting video about the engineering of the telescope:

    According to the JWST Blog, they’ve fully tensioned three of the five layers of the sunshield. The observation side is cooling down. Tomorrow, they plan to finish tensioning the sunshield.
    If we have to march off into the next world, let us walk there on the bodies of our enemies.

    Sunshield was fully-tensioned yesterday. The secondary mirror is being deployed. The side with the telescope is down to -323degF.

    0 Kelvin (aka "Absolute Zero") is -459.7'F. -323F is some serious cold. Liquid Nitrogen is -320'F

    The secondary mirror is fully deployed. Three major evolutions left, 2/3rds of the way to its L2 orbit.

    The telescope’s fully deployed. Now comes sliding into the L2 orbit and calibration/tuning.
