    We'll get that thing up there one of these years. While I don't expect it to be too soon, I can't wait to see what kinds of next generation space telescopes are planned to take advantage of the gigantic fairings of the next generation launch vehicles.

      I really do hope that the labyrinth-themed Rube Goldberg-esque deployment sequence of the James Webb Space Telescope actually works...

      All that work to fit in a five metre fairing, with hundreds of moving parts, of which essentially all of them are critical to operating.

        Definitely calls to mind the old mantra of "the best part is no part at all". I wish we had rockets with big enough payload volumes that you could just chuck an 8m single-segment mirror into orbit...

        It's a shame that the thing couldn't have just been manually assembled on-orbit at the ISS or something before being sent out to L2. Delta V requirements would probably nix that, but after so many cost overruns and years of delays with the current plan, one wonders which would have been easier.

      Holy shit, that alt-text: Randall was bizarrely prophetic here.

      Holy shit, that alt-text:

      Since delays should get less likely closer to the launch, most astronomers in 2018 believed the expansion of the schedule was slowing, but by early 2020 new measurements indicated that it was actually accelerating.

      Randall was bizarrely prophetic here.

      It's not just time delays. Every time they run out of money, Congress debates whether or not to throw more money at it. One of these days, they'll decide 'not'.

        Yeah, hopefully it goes up before we roll the congressional dice enough times to get the project cancelled. Considering how painfully close it is, I'm pretty optimistic.

    They have enough reserve funding to delay a few months. Longer, and they will need a new provision from Congress.
