    COMPLETE SLICE OF MARTIAN METEORITE NWA 7397
    SNC - Shergottite / Mars Rock
    Sahara Desert, Morocco

    Similar to the previous Lot 87319, this is a thin complete slice from the largest meteorite that was part of the NWA 7397 Martian event. Meteorites from Mars are among the most exotic substances on Earth. In addition to many arcane markers, Martian meteorites share the following fundamental characteristics: they exhibit an unusually young crystalline age (so they cannot be from Earth); they contain water-bearing minerals (so they cannot be from the asteroid belt - the origin of 99.9% of all meteorites); there is evidence of a planetary sized gravitational field on their crystalline structure (which then makes the most likely candidates of origin our two closest neighbors - Venus and Mars). The link to Mars was speculative until an analysis was conducted on the glassy inclusions of two suspected Martian meteorites. In this glass were tiny voids, and in these voids were tiny volumes of gas. In 1997, the technology existed to analyze the gas - and it matched perfectly with the signature of the Martian atmosphere as reported by NASA's Viking Missions to Mars. The delivery mechanism was an asteroid impact which jettisoned material off the Martian surface into an Earth intersecting orbit. Accompanied by the scientific abstract detailing its mineral and isotopic composition, this is a select complete slice of a rock from the planet Mars.
    It measures 5.5 x 3.25 x 0.1 inches (138 x 83 x 2 mm) and weighs 48.53 grams.
