Block Island meteorite, officially. named Meridiani Planum 006 shortened as MP 006, was found on Mars by the ''Opportunity'' rover on July 17, 2009. It is about across.


History

Block Island was the first of three iron meteorites encountered by the rover on
Meridiani Planum The Meridiani Planum (alternately Meridiani plain, Meridiani plains, Terra Meridiani, or Terra Meridiani plains) is either a large plain straddling the equator of Mars and covered with a vast number of spherules containing a lot of iron oxide or ...
within a few hundred meters, the others being Shelter Island (the second meteorite found), and Mackinac Island (the third one found). No strong evidence exists concerning when Block Island may have fallen on Mars, though atmospheric conditions would have favored its arrival in the late Noachian period. Block Island may be extensively weathered, or conversely the features covering it may simply be the regmaglypts formed by its passage through the atmosphere. Contrary to some claims, Block Island is not too large for the modern martian atmosphere to produce, though the denser the atmosphere the more effectively it would produce Block Island mass meteorites.
