James Webb Space Telescope, NASA's Next Hubble, Delayed Yet Again (space.com) 55

Posted by BeauHD from the sounds-familiar dept.
The launch of NASA's next flagship space telescope has been pushed back another seven months. Space.com reports: The liftoff of the $9.8 billion James Webb Space Telescope has been delayed from March 2021 until Oct. 31 of that year, NASA officials announced today (July 16), citing technical difficulties as well as complications imposed by the coronavirus pandemic. "Webb is the world's most complex space observatory, and our top science priority, and we've worked hard to keep progress moving during the pandemic," Thomas Zurbuchen, associate administrator of NASA's Science Mission Directorate, said in a statement. "The team continues to be focused on reaching milestones and arriving at the technical solutions that will see us through to this new launch date next year."

NASA officials attributed three months of this latest seven-month delay to the coronavirus pandemic, which forced many NASA centers to impose mandatory work-from-home orders. "Risk reduction" work on complex Webb tech, such as the observatory's huge, foldable sunshield, added two more months. The remaining two months were added for "schedule margin," giving the mission some breathing room on its long road to the launch pad. But the schedule slip won't increase the 13,670-lb. (6,200 kilograms) Webb's hefty price tag, mission team members said. "Based on current projections, the program expects to complete the remaining work within the new schedule without requiring additional funds," Gregory Robinson, NASA Webb program director at the agency's headquarters in Washington, D.C., said in the same statement.

      The schedule is working perfectly. Remember, this is a cost plus contract. They $billions of taxpayer money stop flowing if they ever actually finish the thing. Judge by their actions, not their words: their goal was never to launch a telescope and do science, their goal is maximum taxpayer dollars to congressional districts.

  • This is by far the strongest argument for a standardized spacecraft design.

    Design a standard, versatile exploration spacecraft bus and mass produce it. Make it hollow so that instrument packages can fit inside it, including telescope optics. Force all exploration projects to tailor their instruments to fit that bus. Funding will never be for a bespoke probe, only for individual instruments. Multiple instruments can be piggybacked on one bus, but if they're not ready by launch time then the bus launches with

      It has its limits though. Planetary exploration requires different spacecraft depending on where in the solar system you're going, with large differences in e.g. thermal design, radiation tolerance and power systems.

      Great idea! Now you've limited the maximum size of the optics and therefore the resolution to a small fraction of the JWST. If you did that, the telescope would be of vastly inferior performance. And where would the su

      Just what standardized design could you come up with that could accommodate a 6.5-m telescope that needs to be kept extremely cold? It's not like there are a lot of other spacecraft - existing or even proposed - that come close to JWST in size and complexity.

      The delays in this program have nothing to do with the spacecraft bus. The basic infrastructure to keep a satellite running is pretty well understood. The scientific inst

      Do you want a boondoggle, I mean Space Shuttle? Cause that's how you get a space shuttle. Standardization only adds value when you are doing relatively the same thing over and over again. Like, say, earth observation satellites. You can compromise on instrument design to fit a standardized bus relatively easily. If you have to design your "standard" to be able to accommodate things like a giant mirror then you have a standard that doesn't work well for anything else.

    • Respectfully, this is way off base, and is based on the assumption that design and engineering challenges have been the source of JWST delays.

      JWST has had technical delays as the contract award included a few "scheduled inventions", but these delays were tiny compared to those caused by congressional budgets changing and politically induced leadership chaos.

      The problem with JWST isn't the contractor or the engineering. The problem is that Congress funds and manages NASA as a state level jobs and political

      Well for some things you are definitely right, I'm not an expert, but orbital telescopes are not exactly numerous, so there has really been no point in developing a "standard space telescope platform", I would imagine that a space telescope has quite different hardware than say a geostationary coms satellite

      Planning a budget and a launch date on something that had never been done before is already utterly ridiculous, and leads to exactly the bugs and "ripens at the customer" release of what are de-facto early betas of software, games, etc.

      Look, this is not an industrial revolution factory assembly line!
      You cannot plan what you do not know yet! That includes invention, creativity, and engineering. If it was known, it would not need that kind of work.
      And if you plan it anyway, you cannot plan its quality anymore. Which migh fly with your sleazy hairstyled cocaine addict suits in certain industries, but is a freaking bad idea if it's a super-complex telescope that will be insanely far away and impossible to repair once it's launched.

      I call it the innovation uncertainty principle.
      But the older saying is: "High speed, low price, high quality. Choose two."

      E.g. in the games industry, they just develop a prototype, look what is still missing, and develop another prototype, until that, let's be honest, completely arbitrary time or money, has ran out... then release.
      I don't want a crashing buggy telescope with zerp patchability.

      Let them take their time. And only say stop if you know it actually isn't worth the time or money anymore. (Ignorance does not count as knowing.)

        Accepting the truth of the above statement [and it is true] is, however, to miss the point. This is an argument based on non-equivalence.

Sure, the estimates before the project begins can be off in a project with unknown unknowns, but the time and cost estimates should rapidly become more accurate over time. Even in a multi-year project, by the first year you should have a very clear understanding of your rate of progress and how to project that forward to an accurate completion date.

      Without the telescope nothing is real either. When the light from that cute chick reaches your eyes, she's also no longer there where you see her and what you see are colored hair with extensions, a botoxed face with fake teeth, a fake nose, not to mention the fake titties, but at least the light from those reaches you a tiny little bit earlier than the face.
