Like other members of the shergottite–nakhlite–chassignite (SNC) group of meteorites, ALH84001 is thought to have originated on Mars ...
The researchers are still exploring the source of the remaining roughly 15% of known Earth meteorites. Space rocks have played a role in shaping the direction of life on Earth.
Only about 6% of meteorites are iron meteorites or a blend of rock and metal, the stony-iron meteorites. Modern classification of meteorites is complex. The review paper of Krot et al. (2007) [17] summarizes modern meteorite taxonomy. About 86% of the meteorites are chondrites, [18] [19] [20] which are named for the small, round particles they ...
Meteoritics [note 1] is the science that deals with meteors, meteorites, and meteoroids. [ note 2 ] [ 2 ] [ 3 ] It is closely connected to cosmochemistry , mineralogy and geochemistry . A specialist who studies meteoritics is known as a meteoriticist .
UK scientists believe they have identified the source of one of the rarest meteorites to ever fall on Earth. The Ivuna meteorite landed in Tanzania in December 1938 and was subsequently split into ...
The Maine Mineral and Gem Museum wants to add to its collection, which includes moon and Mars rocks, Pitt said, so the first meteorite hunters to deliver a 1-kilogram (2.2-pound) specimen will ...
Nakhla meteorite's two halves, showing its inner surfaces after being broken in 1998 Nakhlites are a group of Martian meteorites , named after the first one, Nakhla meteorite . Nakhlites are igneous rocks that are rich in augite and were formed from basaltic magma about 1.3 billion years ago.
Lunar Sample 14321, better known as "Big Bertha", is a lunar sample containing an embedded Earth-origin meteorite collected on the 1971 Apollo 14 mission. It was found in the Fra Mauro region of the Moon. Big Bertha is the first discovered meteorite from Earth, and the embedded meteorite portion is the oldest known Earth rock.
