Upgraded Hubble To Be 90 Times As Powerful

Posted by kdawson on Wed Jan 09, 2008 12:19 AM
from the new-glasses-and-oh-here's-your-binoculars dept.
The feed brings us a New Scientist review of the repairs and new instruments that astronauts will bring to the Hubble Space Telescope next August (unless the launch is delayed). The resulting instrument will be 90 times as powerful as Hubble was designed to be when launched, and 60% more capable than it was after its flawed optics were repaired in 1993. If the astronauts pull it off — and the mission is no slam-dunk — the space telescope should be able to image galaxies back to 400 million years after the Big Bang.

      When the new director took over one of his first acts was to reinstate the Hubble upgrade. Really it's one of the most cost effective missions that NASA can do from a science per dollar perspective and one of the few ones that needs the shuttle before it's decommissioned.

        Just prior to the "Return To Flight" mission after the Columbia mission, I had the opportunity to talk to two retired shuttle astronauts, one of whom had been involved in the first Hubble servicing mission. I asked them whether given the opportunity, they'd be willing to fly another mission to the Hubble even without the post-Columbia modifications. To a man, they both said "Absolutely, In a heartbeat." In their eyes, the Hubble was one of the few truly useful missions performed by the space shuttle.

          It's not bloody pictures! It's seeing proof that we have our maths right.

          • Without them, Hubble would have failed to capture public interest and consequently would have been lobbed into the atmosphere the first time they considered its fate. So, frankly, it is all about the "bloody pictures" because the math only interests a small minority.

              That may be true but there also may be benefits in learning to repair what we have, that go beyond merely the "launch and trash" philosophy, i.e. when resources are limited. What kinds of new technologies will be spawned to learn how to repair existing stuff in space and what will be learned I think is just as valuable since sooner or later we will have to learn whether others want it or not.

              Not really, even the most pessimistic calculations put the cost of a manned mission at well under $2B whereas the most optimistic predictions for the cost of the James Webb Space Telescope (JWST) put it at $4.5B with typical overruns that puts it closer to $6B and it's not even planned to launch until 2013.

              My favorite part of all of this is that your argument basically consists of an unsupported claim that hubble accomplishes nothing more than taking pretty pictures, followed by what is essentially an exploration of the opportunity cost of funding hubble's repairs. Exactly what kind of argument is that? Of course $350 million could be well spent on other areas of research, that's not an argument against the repairs, that's the inherent nature of the decision. By choosing A, you necessarily lose out on options B, C, D, etc.
              What you have not done, at all, in either of your posts here is offer a single reason that hubble is undeserving of these funds. Clearly, you think hubble is a wast of money. Clearly its a lot of money and other areas of research could benefit from getting it instead. ...and?

              Similarly, keeping the Hubble alive because we've already sunk billions is just trying to justify sunk costs despite the fact that we aren't getting a positive marginal return on our investments. The hole just keeps getting deeper, because we won't stop digging.
              If one kept looking for the immediate, short term ROI, most pure science projects would never get funded at all. Increasing the knowledge of humanity is never (alright, almost never) a waste of money. There's no telling what practical applications the next discovery might have.

              I'm sure Max Planck would be quite amazed at what we've gotten done using the concept of quantum, even though it seemed to be little more than a mathematical trick when he first thought of it.

      The fundamental problem with your statement is that you assume that the $$$ would otherwise have been used to change lives in a big positive way.

      Put very simply, through science, we gain an understanding of the world, and universe around us, how it operates and how we can interact more effectively with it.

          You could argue the same thing about all fundamental research... But how much of todays practical applications would have been discovered if we hadn't sponsored research in quantum physics?

          Now of course the direct link between Hubble telescope and daily applications is less obvious, but it did determine the Hubble constant (well a more accurate estimate) and determined that the expansion of the universe was accelerating... Now you can challenge the usefulness of these discoveries all you can, but I somehow believe that in the long run, understanding the physics that rule this universe will generate vastly more practical applications (and revenues) then the current (and already beaten) missile defense system...

          In the long run we're all dead, but that doesn't mean we should focus solely on short term objectives (and I'm very very glad our ancestors didn't)/

      You've been modded flamebait by someone, but it's a legitimate question that many people have when looking at instruments designed for pure science and discovery. There are quite a few really good arguments about why the Hubble should be around which are based on the science mission, but I'll give you an example of positive spinoffs that affect our daily lives. Google will give you many more.

      One NASA-driven development has already found its way into clinical use as part of the LORAD; stereotactic needle
      biopsy system. The charge-coupled device (CCD) camera used in this system was originally designed and built for use
      in the Hubble Space Telescope Imaging Spectrograph, and provides a high-resolution, high-contrast image in real time
      to guide a physician in the accurate collection of a biopsy sample from suspicious imaged breast lesions. The Hubble
      CCD, coupled with a high-speed phosphor screen, gives greatly increased sensitivity, contrast and resolution over
      previous methods, The result is a less traumatic, lower cost ($800 vs. $2,500 typically for surgical biopsy), non-surgical biopsy procedure for the more than 500,000 American women who undergo breast biopsies each year.
      -------

      Here, Hubble directly increased the ability for us to find cancers. When you look at a dollar amount, (2500-800)*500000 gives us $0.85 billion per year. Note that this article was published in 1996; today, mammograms and biopsies are much more common. To keep things simple, if we assume a constant number of patients, the Hubble CCD alone has directly resulted in cost savings of $9.35 billion (let alone lives saved). Also note that the cost of scalpel biopsies is mostly based on labor, and so would not have dropped much beyond the $2500 level; CCD's have become very inexpensive (relative to costs in 1996) and so the savings would actually be significantly larger than calculated here.

      Anyone know the true cost of a non-surgical biopsy today?

      Wikipedia says the cumulative cost of the Hubble program has been 6.5 billion dollars. The population of the United States is approximately 300 million people. That means that the Hubble over its entire lifespan cost every man, woman and child in the United States $21.67 each. So no, all the monies spent on it would not have changed lots of American lives in a big positive way. Considering that all that money was paid over the course of the last 18 years, that means each person paid the equivalent of a little over a dollar per year for the wonderful pictures and discoveries it made. So, are the secrets of the universe, or even just pretty pictures worth a third of a cent per day? I think so. 6.5 billion dollars in the hands of one person is a lot of money. 6.5 billion dollars spread across 300 million people over 20 years is practically nothing. If you want to consider real money, consider the > 450 billion dollars spent over the last 5 years on the Iraq war, or the 450 Billion dollar Defense budget spent every year which doesn't even include war operations.
      • I came in here to say almost exactly what the parent post said - If you had taken all the Hubble money and rather spent it on some social program it would come down to basically $1 per US citizen per year over the last 20 years.

        Money spent on pure science is usually a good investment because the returns are cumulative. The new knowledge that we gain can potentially benefit the human race in all perpetuity.

      "big positive way" doesn't necessarily equate to giving people handouts or curing diabetes. If all we ever spent our money on was egalitarianism, our lives would be so boring we wouldn't see the point.

    Most people think the magnification of a telescope is the most important number, whereas astronomers are typically more interested in the light-gathering power, as measured by the aperture. What's really being increased by a factor of 90 is neither the magnification nor the sensitivity, it's apparently the product of the sensitivity and the area of the field of view. The argument seems to be that this is an important figure of merit if you're doing a survey of faint objects, such as very distant galaxies.
    • astronomers are typically more interested in the light-gathering power

      Isn't this just a fancy way of saying they're interested in capturing fainter objects?

    The summary is a bit misleading about the 60%.

    FTA: "HST will be about 60% more powerful than it was right after the third servicing mission, before ACS and STIS failed."

    The 1993 servicing mission generally restored the designed capabilities of the Hubble, the so-called "factor of 90" that the article mentions. Major new improvements and capabilities came with each servicing mission, culminating in the March 2002 servicing mission that installed the Advanced Camera for Surveys (ACS).

    The upcoming installation of the new Wide Field Camera 3 (WFC3) and the Cosmic Origins Spectrograph (COS) will improve the combined sensitivity and field of view by 60% over the Hubble as it was after March 2002 (and before ACS died).

    To be fair... by the same metric, modern ground-based telescopes with large format CCD and infrared arrays are on the order of 100 times more powerful than they were in 1990 as well. In the near infrared, the gains are closer to a factor of 1000!
