      I was thinking the same thing ... cue "instrument waving in wind" jokes.

    Insert joke here about my "telltale instrument" waiving in the wind.

    OR... it's proof that these martian landings are staged and never really occurred in the first place!

      Being able to hear the wind blow on another world would be SO cool, even though probably rather useless.

      Maybe next time they send a probe to Mars, they will put a directional wind vane and an anemometer on board. A dangling wire just doesn't do it. Only shows a wind is present.

      Audio there would most likely sound the same as wind here, so nothing new.

        I would suggest a spectrum analysis of the audio received from wind noise would be quite valuable, unless NASA happened to also pack along a Doppler radar unit. Instead of guessing if that really *was* a dust devil that passed by, an audio analysis would probably provide definitive proof.

    The telltale is a small weight dangling from a vertical boom. More sophisticated instruments would have weighed more, so they opted for this minimal weather instrument.

    The most Illustrious Council of Elders has decried this latest humiliation inflicted upon its noble citizens by the latest mechanical invader from the blue planet. K'breel, speaker for the Council, stressed that this most recent insult would not be taken lightly:

    Gentle Citizens, today my gelsacs are engorged in anticipation of the impending demise of the mechanized monsters of the blue planet. One hundred and thirty six days have passed since their latest mechanical terror has landed, and this -- this futile mocking gesture, such a pale imitation of our species' noble and pendulous glory -- is all it has come up with. Citizens, the creatures from the blue planet are so weak that they can barely muster up the strength to mock us. Winter approaches, and with it, darkness. Rejoice, podmates, for our final final victory against their pathetic mocking contraptions shall come at last!

    When a small group of younglings questioned whether the telltale waving of the enemy's instrument was perhaps due to a gust of wind, K'Breel ordered their gelsacs pierced on the spot.

    This series of images show Phoenix's telltale instrument waving in the Martian wind. Documenting the telltale's movement helps mission scientists and engineers determine what the wind is like on Mars.

    On the day these images were taken, one of the images seemed to be "out-of-phase" with other images, possibly indicating a dust devil occurrence. Preliminary analysis of the images taken right before and after the passing of this possible dust devil indicates winds from the west at 7 meters per second. The image taken during the possible dust devil shows 11 meters per second wind from the south.

    These images were taken by the lander's Surface Stereo Imager (SSI) on the 136th Martian day, or sol, of the mission (Oct. 12, 2008). Phoenix's telltale is part of the Canadian Space Agency's meteorological package on the lander.

    The Phoenix Mission is led by the University of Arizona, Tucson, on behalf of NASA. Project management of the mission is by NASA's Jet Propulsion Laboratory, Pasadena, Calif. Spacecraft development is by Lockheed Martin Space Systems, Denver.

    How many landers must we see touch down
    Before you can send one that's manned?
    Yes, and how many times must you scoop the soil
    Before you get some in the pan?
    Yes, and how many sols must the dust storms fly
    Before there's ice on polar land?
    The answer, my friend, is blowin' in the wind,
    The answer is blowin' in the wind.

    As a carryover from a previous topic regarding the smell of space, I wonder if NASA is trying to determine the smell of the martian atmosphere.

    While we have no humans in place to do the smelling, could samples be taken then sent back for "smell" analysis?

    Previous topic( http://idle.slashdot.org/article.pl?sid=08/10/16/1533239 [slashdot.org] )already touched on the importance of the smell of space, but what about Mars?

    The fact that there is mass pushing that little flag around leads me to believe that there are also chemical components to provide smell "signatures".

      Atmosphere on Mars is 95% CO2, 3% N, 1.6% Ar + trace. I'd guess you can't smell the Ar (you can't smell .9% Ar on earth), and you can't smell Nitrogen, so that pretty much leaves us with the strongly acidic smell of CO2.

      This is all based on conjecture, so things may changes in local areas, during various weather conditions, or if/when we get more accurate measurements from the surface.

    Many seem to forget that Mars does possess an atmosphere. Therefore, has wind and other 'weather' phenomenon.

    Just not anything we can breathe, mostly carbon dioxide.

    • It probably had a thicker atmosphere when its iron core was moving to create a magnetic shield from the solar wind. (like the earth)

      Too bad we can't have a big tether like this (http://www-istp.gsfc.nasa.gov/Education/wtether.html) and connect one end to the now solid core (50KM below surface!). Then maybe a new a magnetic shield could be created.

      ...and bloody little of it, less than 1/100 as dense as our atmosphere at the surface. A wind sufficient to move part of that instrument would be pretty stormy weather by Martian standards.

  • This is quite refreshing for me. Usually NASA has something entirely different waving the wind.....

  • Oh, wait. Nevermind [wikipedia.org].

  • At least until it is explained to their top theologists that they should not declare war on the martian "Dust Devils" and that the lander did not, in fact send back a picture of the Virgin Mary.
  • I had no idea a tampon could be use to measure the wind. Great idea though, it's light, large so it'll react to the least variation in wind and hangs from a string.
