    Mars Rover Opportunity Finds 'Rich' Clay Deposits

    Analysis by Irene Klotz
    Fri Dec 21, 2012 06:33 PM ET

    NASA's long-lived Mars rover Opportunity that beat newcomer sister probe Curiosity to an area containing water-formed clay minerals, has found that the spot may be far richer than scientists first realized.

    A new study looks at chemicals spotted by a Mars-orbiting spacecraft to conclude that Endeavour Crater, which Opportunity reached in August 2011 after a 1,000-plus day, 13-mile trek across the plains of Meridian, is flush with a variety of clays, which on Earth, form in the presence of water.

    Both found clear evidence that water has played a role in Mars' history, but the chemistry of the liquid was determined to be highly acidic, similar to battery acid, and not very friendly to life as we know it.

    Clay minerals point to a different story, one involving a neutral water chemistry -- water you could drink, lead rover scientist Steve Squyres, with Cornell University, told reporters at the American Geophysical Union conference in San Francisco this month.

    Not a sunrise, but a galaxy rise
    A morning filled with 400 billion suns
    The rising of the milky way"

    If we do not destroy ourselves
    We will one day venture to the stars" -Carl Sagan
