    Even though the Hubble Space Telescope was expensive initially, you must admit that it has been cheap and easy to repair. This new telescope would be located all the way down in Antarctica. Has anyone priced flights to Antarctica lately? When there's a problem, it's not like you could just hop on the next Space Shuttle and slap another lens in. And plus it's COLD down there! It'd probably need some kind of heater or something. Think of the electric bills!

          As for the "It can't see portions of the sky" argument; aside from my earlier objection that what is left is not exactly a small area to look at, couldn't one build another somewhere in Greenland or Alaska? The total cost (assuming the Northern telescope could be built for around the same amount) would still be a fraction of the cost as the Hubble, and would still be much easier to maintain.

      When the sun is up (summertime) you can observe in the infrared and submillimeter. Hubble's observing efficiency is about 50% due to the requirement to avoid the Earth, the South Atlantic Anomaly, slew time, etc.

      The limitation is sky coverage is not important for many astronomical programs. Important regions such as the Galactic Center, the Magellanic Clouds, and the South Galactic Pole, are all visible.

      There are tradeoffs.

      Hubble is unable to look at most patches of sky for a full day because it orbits near the earth, whereas this telescope can sit and look at most anything in the southern sky for months at a time.

      Hubble is also unable to look at that part of the sky which is near the sun. (Obviously this varies with the season).

      Most of the observing done with Hubble is not really time critical... having two identical Hubbles that could only operate during six months of the year would be almost as good as having the actual Hubble which operates year round. Since this telescope is so much less expensive than Hubble, you could easily build two of it if its observing time is really that important.

      Hubble is more versatile than this Antarcic telescope would be, but I'd say it's due more to atmospheric absorption. There are differences in observing constraints, but it's just not a huge deal.

It really can't look at the whole sky, because it needs to avoid the sun, earth, moon, and other bright things.

I'll just comment that making optically flat mirrors was very hard (much harder than the normal curved mirrors) last time I heard, but there might be new technology to help here.

    There are basically three competing locations: space, Antarctica, somewhere else on Earth. There is an order of magnitude or more in accessibility and cost between each option.

    Space:
    Pro:
    Access to the full range of wavelengths - no atmospheric absorption or emission. (Particularly useful in UV and IR.)
    No atmospheric bluring - diffraction limited resolution at all wavelengths
    Can observe almost any part of the sky at any time.
    Con:
    Hugely expensive
    Very inaccessible - service missions are either impossible or cost hundreds of millions or more
    Size limitations on launch - either the telescope is smallish (Hubble) or needs even more expense to 'unfold' in orbit (new generation space telescope).
    Very hostile environment: cold on one side, hot on another, radiation belts, ...

    Antarctica:
    Pro:
    Access to wavelengths difficult or impossible to access elsewhere on Earth (mostly mid to far IR. The ozone hole presumably helps out in UV also.)
    Best seeing on the planet: very little atmospheric blur much of the time.
    Con:
    Can only ever view half the sky
    Unusable during summer
    Very expensive
    Poor accesibility: Only during summer, only at great expense.
    Hostile environment: extreme cold. Possible build up of ice by sublimation deposition.

    Anywhere else:
    Pro:
    Cheapest
    Daily access, can drive a truck up to the telescope
    Can have astronomers on site, e.g. debugging new detectors
    Can see the northern hemisphere
    Con:
    Poor seeing
    Many interesting wavelengths inaccessible or hard to observe
    Unusable during the day

    We need all three - space for what we can't do on Earth, Antarctica for what we can't do elsewhere (except space, which costs more).

      They can point the telescope at polar bears once in a while, if that would be OK.

      I'm surprised that you care so much about Antarctica. I'm all for responsibly maintaining the Earth, but I can't find a good reason to object to building one measley telescope. Especially if it will have such a great impact on astronomy.

      Do you object solely on the principle that it was decreed to be a nature preserve, or is there a deeper conviction? Do you believe that a telescope would have a negative effect on the Antarctic environment?

      You are missing something. The Antarctic treaty [nsf.gov] encourages scientific research activities in Antarctica. There is not a single word in that treaty that even momentarily suggests that it would be an awful thing if the research was not expressly about Antarctica itself.

      The later Protocol on Environmental Protection to the Antarctic Treaty, [antarctica.ac.uk] established in 1991, goes into more detail about Antarctica's status as a nature preserve, "dedicated to peace and science." It specifically bans mining and similar activities, and makes clear that all activities in Antarctica must be compatible with scientific research and environmental research in particular.

      But it definitely does not ban non-scientific activities, like tourism, as long as their environmental impact is addresses correctly. And it certainly doesn't ban astronomy (an awful, polluting activity, astronomy! Shudder!).
  • I can just imagine the size of the gyros and retros we will need to rotate the planet so that this Antarctic telescope can view something interesting from the northern hemisphere.

  • At least there is no danger of a "mistake" at the mirror grinding factory causing a "myopia" in the telescope, because I think the Pentagon knows that it can't spy on Earth from Antarctica. However, there is some danger, in having mirrors exposed like that, to crazy Swedes shooting at dogs. Hopefully, MacReady got the damn Thing.
  • "But, unlike them, this telescope would also be a great survey instrument, able to map the whole sky with Hubble-like clarity."
    This is far south enough that some of the northern sky will always be obscured by the earth.

    A couple of people have mentioned that you can't work in the ultraviolet part of the spectrum without going to space. True, and critically important to some science. Also, from Antarctica, you can only see the southern sky, not the north, so this is another limitation.

    These are not good reasons not to build this proposed telescope, just ways in which Hubble is still uniquely qualified.
