NASA Ponders What To Do With a Pair of Free Space Telescopes 97

Posted by Unknown Lamer from the scientists-use-mirror-to-incinerate-kremlin dept.
scibri writes "A few months ago, the secretive National Reconnaissance Office gave NASA two Hubble-sized space telescopes that it didn't want anymore. Now the space agency has to figure out what to do with them, and whether it can afford it. The leading candidate to use one of the telescopes is the the proposed Wide-Field Infrared Space Telescope (WFIRST), which would search for the imprint of dark energy, find exoplanets and study star-forming regions of the Galaxy. The NRO telescope could speed up the mission, but may end up costing more in the long run." A few issues with re-purposing the NRO satellite: higher launch costs because it's bigger, it can't see as far or as much IR (but it can see fainter objects, and could be used in planet detection), and the need for a bigger camera.

    Getting time on the big telescopes has always been a bit of a trial since they are a limited resource and there are a lot of people who want to use them.

    These telescopes do not need some special unique mission/purpose.. just having more capacity and schedule time for a wider group of scientists would be worthwhile right there, at least to the people who get time on them.

    • Which is great, as long as the assessed costs to those researchers/institutions represent the cost to operate, plus a fair amortized launch cost.

      And in order to lift those scopes to their viewing points, you've got to have a solid business plan that shows how these users will be committed enough to justify the investment.

      When you're throwing around $billions, it's not a matter of "build it and hope they show up." (Well, at least I'd hope not.)

        Business plan?

        What part of Astronomy is based on business plans?
        Even if someone is willing to pay to use a telescope somewhere, it's always with grant money. There is no market at work here, its pure science, with little hope of any gain other than knowledge for knowledge's sake.

        • You *still* have to have a financial plan.
          You cannot - I hope to god you cannot - fling a $1.6 billion mission into space without doing some sort of analysis as regards costs.

          If putting that telescope in the sky would be "really awesome" but ultimately you've only got 'customers' for $600 million of the costs, then understand that it's a $1 billion cost, and may or may not be worth that.

    Take a googletour of the newer ground-based visible-spectrum telescopes. Replete w/ new mirror technology and advance adaptive optic systems, these outperform any telescope that can be put into space -- but just in the visible.
    The only good reason to launch a telescope is to do IR and UV work, i.e. wavelengths that are significantly absorbed by the atmosphere.

      Space based telescopes also have one other important advantage over their earth-bound siblings, namely the ability to image a target for extremely long periods of time. Except for the polar regions, telescopes on earth realistically only have 4 to 6 hours of useable imaging time per night. The rest of the time is spent waiting for it to get dark. A telescope in orbit, on the other hand, can stay pointed on a target for days, weeks or months at a time.

      Canada's "Humble" space telescope (MOST), for example, stared at a patch of the sky for 5 years straight. Its mission is to continually watch a group of stars, watching for subtle variations in their brightness which could a) indicate the transit of extra-solar planets and b) help determine the composition of these stars.

      Well, according to wikipedia the cost of a KH11 is about half the hubble. They have economies of scale as well. I never understood with things like the Hubble why they don't make more than one. At almost any step of manufacture the cost to just stick one more whatever on the rig and do what you just did 5 minutes ago is pretty cheap compared to doing the first one.

      It is like saying that StupidCo spent $50M building a single smartphone, but every teenager is running around with an iPhone it seems. Well,

  • Just shows the difference between the level and scrutiny of funding between the military/intelligence sector and the civilian sector. NASA has to go through a long period of request and debate to get a space telescope, while the military just builds a few too many with no comment from anyone.

    • I guess they're like HumVees or other military gear. They're not that expensive until you try to use them.

      Note to self: Value of space telescopes greatly diminished when they are not actually in space.

    • Every time a satellite is built they usually build a spare in case the launch goes wrong. Once they decide they have enough satellites these spares can either be discarded or repurposed. That is probably what happened here.

With a bit of analysis - software or otherwise - it should be possible to develop a detailed _dynamic_ picture at various scales. This would essentially prese

Much of this data will be available to public who may have time to look at things the professionals miss. (I probably overlooked a few projects too).

In the current economic climate, not only are good ideas not being built, but some of the older scopes are being de-funded.

      If it were possible to cut back the military budget (unlikely), you would see a few unemployed engineers (who could probably easily find civilian jobs). You'd also see a drop in profits for all of the military contractors.
