Mars Lander Instrument Waving In the Martian Wind

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

      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.

  6. Late Breaking News from the Council by Tackhead · · Score: 4, Funny

    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.

  7. Site slashdotted, here it is, click link for image by Anonymous Coward · · Score: 5, Informative

    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.

  9. Pardon the tangent..... by Anachragnome · · Score: 4, Interesting

    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 )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".

    1. Re:Pardon the tangent..... by thepotoo · · Score: 4, Interesting
      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.

    I got in big trouble for waving my instrument in the wind.

    Of course, with a string bass, swinging it on a dead calm day would be just as bad.
