    All BS
    Most likley they were given to them so Nikon could say
    Nikon Only in space.
    Then there is no reason why they would not work in space. More BS.

  2. NASA uses *core memory*, in the name of the Goddess, for their
    5 onboard shuttle computers!

    NASA hast just recently approved of 80386 (aka Intel 386) --- as
    in 2 generations BEFORE the original "division bug" Pentium ---
    for space flight!

    Shall we now all switch to 80386 computers? I still have a 386SX,
    20MHz --- that's 0.02GHz for you --- from 1990, back when they
    started to replace 286 in expensive home computers. It had a
    full loadout of a luxorious 4MB RAM (that's 0.039 GB RAM) and a
    huge 40MB MFM-disk. That's 40 MB, as in a "0.04GB hard drive",
    to you 100-750GB hard drive users. That's so small, you have to
    buy a 32MB (not GB, MB!) CF card to be smaller.
    If you still _can_ find so small a card, that is.

    To give you a perspective: That was the time of Windows 1.0.
    Of MS-DOS 3.x and later of the catastrophy called MS-DOS 4.01
    (4.0 was _so_ crashy and broken, they had to do a bugfix release
    --- and still it crashed very often).

    To give you another perspective: There was no 'accellerated'
    graphics card. Not 3D, not even 2D. We were lucky to *have*
    enough memory on the card for a 400x320 resolution graphics.

  3. Ah, yes, space is sooo cold that one of the first things the
    space shuttle does is open the bay doors to expose the radiators
    so they can get rid of excess heat.

    Additionally, the astronauts in the space shuttle usually do _not_
    contract frozen fingers, ears and toes.

    Space is not "cold", space is a very good insulator --- it's the
    "vacuum" in "vacuum thermos bottle". Getting rid of 100W
    heat from the average human being is a real problem.

  4. It ain't that bad, unless there's a solar flare (and then even
    down here problems can appear). After all, the shuttle stays in
    LEO, well inside the magnetic field of the earth (polar routes
    may be more of a problem near the poles) and _well_ this side of
    the van Allen belt.
    Inside the manned parts of the shuttle there should be not
    even soft vacuum, as that is considered somewhat unhealthy for
    biological lifeforms. Now, if you were to EVA with the camera,
    that's be different.

    Thats why there is on SEX in space, the heat would be really high.

  6. If it works in these mission critical applications while protecting the
    safety and lives of the crew, why use generic garbage?
    Smart move! You'll never see an AMD or Cyrix chip leaving the earth's
    Absolutely! The 80386 is still alive and well in a lot of mission critical
    boards. I think I still have mine. Hell, I even had a math coprocessor and
    a pair of Seagate ST-225 drives. In its day that system was cutting edge
    and indestructible.

  7. LOL!

  8. Do you have _any_ idea how hard it is to find people even
    able to thread core memory these days? You know, that's the
    stuff that was well-tested in 1972, and has not been produced
    in decades now, except on order, by hand.
    You are quite probably wrong.
    You may want to check all the laptops and electronic gear that
    has been flown as "personal items" or noncritical or entertainment
    hardware. Don't forget e.g. Spaceship One.
    In it's day, the sword was a cutting edge weapon.
    It's still in use by some people, mostly for ceremonial
    reasons or historic reenactments.
    Try a larger hammer.

  9. That's rather a political problem of the NASA than a heat problem
    --- any strenous activity wil produce more heat.

    Additionally most techniques -- from tightening screws to using
    the toilet -- need gravity to work, so different techniques have
    to be learned and used. Humans are _very_ adept at overcoming
    problems, so consider that a mostly solved problem, or use Google.
