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''' by the Meteoritical Society in October, 2005 (meteorites are always named after the place where they were found). ''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 Endurance Crater . This was the first meteorite of any kind identified on another solar system body — none were found on the Moon . Readings from ''Opportunity'' Meridiani Planum , the part of Mars where this meteorite was found, is suspected to have once been covered by a layer of material with a thickness of as much as 1 Km which has been subsequently eroded. This means that on impact this meteorite might have created a crater, but evidence of that crater may have been subsequently erased by millions, or even billions, of years of erosion. In any case, the meteorite does not show much sign of Rust despite Mars's oxidizing environment, so it either fell recently or was buried until recently. It also shows little sign of weathering or exposure to water. Note that the term ".
