Heat Shield Rock is a basketball-sized iron-nickel meteorite found on Mars by the Mars rover Opportunity in January 2005. The meteorite was formally named Meridiani Planum meteorite by the Meteoritical Society in October, 2005 (meteorites are always named after the place where they were found〔The Meteoritical Society, Guidelines For Meteorite Nomenclature, 2.2 Distinctive names ()〕). ==Discovery== Opportunity encountered the meteorite entirely by chance, in the vicinity of its own discarded heat shield (hence the name). Opportunity had been sent to examine the heat shield after exiting the crater Endurance. This was the first meteorite found on another planet and the third found on another Solar System body — two others, the millimeter-sized Bench Crater and Hadley Rille, were found on the Moon.
