NASA's Gypsum Find Clear Evidence There Was Water On Mars

Posted by timothy on from the plaster-of-mars-would-be-really-expensive dept.

First time accepted submitter RCC42 writes "The Opportunity rover has found evidence that liquid water once flowed on Mars, through the discovery of gypsum — a mineral that can only be formed in the presence of water. Though other evidence in the past has suggested highly acidic water on Mars, this is the first evidence for water with a pH suitable for life as we know it."

    The US Dept of State is a reliable authority of unbiased information and analysis? Christ! You would have made a great Soviet.

    They weren't trying to be. That's one of the strengths of these memos.

    Then there's the entirely discredited IAEA citing. This was shredded. Another sad, neocon fairytale, like Condoleeza's "Smoking Gun in the form of a Mushroom Cloud". Oh. She represents an example of State Dept. accuracy and lack of bias, herself.

    Discredited by whom? I won't take such claims seriously unless I can evaluate the merit of the claim.
