    Rock Tasting at Biosphere 2

    By Susan Swanberg | December 11, 2012

    With a mischievous grin and gleaming dark eyes, Dr. Dragos Zaharescu raises a small spatula to his lips and tastes. At his feet are four containers, each filled with a different type of ground rock—granite, basalt, rhyolite or schist. Zaharescu will blend this rock with bacteria or fungus, creating a sandy medium for seedlings he grows here under the glass dome of Biosphere 2.

    The dark-haired scientist cleanses his palate with water and tastes another sample. He won’t tell us his opinion yet, but dares us to participate as he serves sand like a sommelier.

    “Which one do you want first?” he says.

    After we sample the ground rock, Zaharescu agrees that granite tastes like salt.

    Biosphere 2, where he does his research, is about 35 miles north of Tucson, Ariz. The dome of Biosphere 2 rises from the mesquite savannah like a cathedral for the celebration of science. Assorted biospherians and scientists have studied within this glass vivarium. The enthusiasm for discovery has not waned since the original crew of biospherians lived here two decades ago. Their mission: To survive for two years sustained only by the food they grew beneath the dome.

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

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