Also see the Where is Webb? dashboard- https://jwst.nasa.gov/content/webbLaunch/whereIsWebb.html https://jwst.nasa.gov/content/webbLaunch/whereIsWebb.html It's almost there, but there will still be about six months of cooling down and calibration before we see anything from it.

We are very likely to see first images much sooner than that. Although first science needs to wait for full cooling and alignment, they will be producing images during that process. The expectation is that some of these images will be published, mostly for PR.

    The scope can’t image anything at all right now, and it will be quite a while before it can. Each mirror segment was firmly supported to withstand the violent forces at launch. In the past few days, the two 3-segment wings swung into position and every mirror segment moved slightly so that now they can be aimed by their actuators. Each segment has actuators on the perimeter that will fine tune the pointing and one in the center that can deform it slightly to change focus. Each one will now need to be fine tuned. There are also many adjustments to be done in the secondary optics. Inevitably, surprises will crop up as well and have to be dealt with. They do this quietly now for PR reasons. While the Hubble was being commissioned, some engineers talked freely about the things they were dealing with. At first it was very interesting to follow along. But once it was determined that the primary trouble was misconfiguration of the objective, all the chatter stopped. Since then all space missions tightly control their press. This is understandable but makes it a little less fun to follow along. The good news is that most of the single use motors and actuators have done their thing and and are now retired. The ones that remain (like the mirror pointers) are based on designs that have worked many years on many spacecrafts. It is great to see the project get to this stage. I can’t wait to read about what we find out there.

      Thanks, now I'm looking forward to the inevitable (even more) pop-sci explanation: "imagine waking up double-vision drunk, but instead of two eyes going astray it's eighteen eyes. And it all happens while you know for a fact that you won't be able to tell up from down anytime soon"

  IIRC the plan is to wait until everything is calibrated and tested before releasing any images, to allow the first public images to "wow" everyone.

    From a PR perspective that would not be very smart. Everbody wants to know that it works in principle and if the images that it can make today are not quite as good as the ones that it will make six months from now that gives more points in time to make the public aware of what the telescope can do and what an amazing achievement it is. I fully expect NASA to release a 'first light' image in the near future and if they do not I'll be sorely disappointed.

Measured in a choice of 'English <or> Metric'.

  It's always a bit jarring to see scientific data presented in non-metric units, even in the US. But as an American, I only understand density in terms of Libraries of Congress per Olympic Sized Swimming Pools

    What is the base unit of "Libraries of Congress per Olympic Sized Swimming Pools"? Does the expansion rate of the LoC match the expansion rate of the universe?
- mikewarot 5y ago
  It's interesting that the Metric temperature measurements aren't in Kelvin.
  - danbruc 5y ago
    It is even more interesting that it is in coulomb and not degree Celsius or Kelvin.
    - lgl 5y ago
      It's clearly in Celsius, which is the metric system's temperature unit and it is clearly stated on the website's about page: By default the page loads and displays distances in miles, temperatures in Fahrenheit, ie English units (also known as Imperial or USCS system units). If you wish to have the page load and display in kilometers and temperatures in Celsius, ie metric system units use the urls below to select your preferred units.

        GP means they should have used a Capital 'C'.

The real question is, what happens to this page when distance hits 0. Reminds me of this old, favorite LOL: https://www.youtube.com/watch?v=QOtuX0jL85Y https://www.youtube.com/watch?v=QOtuX0jL85Y

30 minutes to go :-). It's 319KM to L2 orbit as I type this.
