  • Description

    Martin-type dust storms are being recreated in a laboratory in New York State in an effort to discover the meterological conditions which ruined the early pictures from the Mariner 9 Mars probe earlier this year. Scientists and technicians at the Rensselaer Polytechnic Institute have been creating Martian conditions in test tubes this month to find out exactly why the dust storms take place.

    SYNOPSIS: This is a Martian dust storm--recreated in a test tube in New York State's Rennselaer Polytechnic Institute. Earth-bound scientists have wondered what caused the global dust storms which ruined the early pictures from the Mariner 9 Mars probe earlier this year.

    Here, the carbon dioxide of the Martian atmosphere is being chilled as it would be at the Martian Polar Cap with the onset of winter. The substance in the tube is as exact a recreation of the atmosphere on Mars as it's possible to make on earth--complete with dust.

    At the opposite end of the tube system spring is recreated by placing a beaker containing warm water over the Martian atmosphere. This represents the warm sun over the polar arm.

    This creates turbulence in the tube--and it happens on Mars, too.

    The turbulence generates a flow of the heated atmosphere and dust which evolves into a violent dust storm.

    The Martian atmosphere in the test tub??? is transported rapidly towards the freezing pole--exactly as it happens o??? Mars and at the same pressure.

    Finally, when most of the carbon dioxide reaches the pole, the violent surface boiling subsides--just as has been happening on Mars. Next winter, the entire process will reverse with the storms moving to the other pole.
