Martian meteorite
A Martian meteorite is a rock that formed on the planet Mars and was then ejected from Mars by the impact of an asteroid or comet, and finally landed on the Earth . Of over 61,000 meteorites that have been found on Earth, 214 were identified as Martian as of October 2018 [update] . [1] These meteorites are thought to be from Mars because they have elemental and isotopic compositions that are similar to rocks and atmosphere gases analyzed by spacecraft on Mars. [3] In October 2013, NASA confirmed, based on analysis of argon in the Martian atmosphere by the Mars Curiosity rover , that certain meteorites found on Earth thought to be from Mars were indeed from Mars.

A Martian meteorite is a meteorite that has landed on Earth and originated from Mars . This could have been the result of an impact of a celestial body on Mars, sending material from Mars into space. Of over 50000 meteorites that have been found on Earth, currently 95 have been identified as originating from Mars, most of which have been found since 2000. [1] Chemical analysis of the martian meteorites suggests that the ambient near-surface temperature of Mars has most likely been below 0 C° for the last four billion years. [2] |

Mars meteorites include three rare groups of achondritic (stony) meteorites (16 objects total) with isotope ratios that are said to be consistent with each other and inconsistent with the earth. It should be pointed out, however, that the isotope ratios do not actually match Mars ratios especially well, to the extent that Mars ratios are known, although they do differ substantially from Earth isotope ratios and from what is known of Lunar ratios. |

Mars Meteorites include three rare groups of achondritic (stony) meteorites (16 objects total) with isotope ratios that are said to be consistent with each other and inconsistent with the earth. It should be pointed out however that the isotope ratios do not actually match Mars ratios especially well to the extent that Mars ratios are known. They do differ substantially from Earth isotope ratios and from Lunar ratios to the extent they are known. All the meteorites are igneous rocks. Lherzolitic shergottites (one from Antarctica, 2 from California) are identified by their Deuterium/Hydrogen ratios. The crystals appear to be 154-187 million years old and they appear from cosmic ray analysis to spent 2.5 to 3.6 million years in space. There are also basaltic shergottites some of which appear from the presence of hydrated carbonates and sulfates to have been exposed to liquid water prior to injection into space. One of the shergottites known as ALH84001 is much older than the others -- about 4.5 billion years. In this respect, it resembles a typical meteorite rather than the other shergottites. The other two types of Martian meteorites are Chassignites and Nakhlites. All appear to have been on earth no more than 35,000 years. Together, these objects are called SNC meteorites. |
