Mackinac Island meteorite was found on Mars by the Opportunity rover on October 13, 2009.
History[edit]
Mackinac Island was the third of three iron meteorites encountered by the rover on Meridiani Planum within a few hundred meters, the others being Shelter Island and Block Island.[2]
Mackinac Island may have fallen on Mars in the late Noachian period and is extensively weathered.[2][5]
