The Mars Exploration Rover Opportunity has discovered that a rock dubbed "Bounce" at Meridiani Planum has a very similar mineral composition to the meteorite EETA79001 and likely shares common origins. Bounce itself is thought to have originated outside the area surrounding
The meteorite EETA79001, a basalt lava rock nearly indistinguishable from many Earth rocks, provided the first strong proof that meteorites could come from Mars. Originally weighing nearly
Three distinct subgroups exist under the name SNC meteorites (after Shergotty, Nakhla, and Chassigny). These Martian meteorite subgroups are classified on the basis of mineralogy, but they all share isotopic signatures, petrologic characteristics. Meteorites from Mars give information on the planet mars. . Except for the famous ALH84001, the relatively young crystallization ages (less than 1.4 billion years for all martian rock and 4.5 billion for ALH84001) is surprising if compared to all other chondrites (more than 4.6 billion years!).
Mars Meteorites (give information about the planet Mars): On March 31 1995, the New york Times and Science magazine reported what had long been suspected: a meteorite from
There are now 30 meteorites known by chemical analysis to be pieces of the Red Planet Mars, which have been launched from the surface Mars by an asteroid impact. The rocks then orbited the sun and hit the Earth as meteorites. The SNC's (Shergottite, Nakhlite, Chassignite) have always been the most desired meteorites for collectors and are also some of the most valuable. Science is almost certain the SNC Group of meteorites derived from Mars because of their young ages, basaltic composition, and inclusion of gases with the same composition as the Martian atmosphere. Composition of gases of Martian meteorites are almost identical to those of samples tested on the Martian surface by the Viking probe (NASA).
The shergottite subgroup is named after Shergotty, an achondrite which fell in
The nakhlite subgroup is named after Nakhla, an achondrite which landed in
The chassignite subgroup is named after Chassigny, an achondrite which fell in
