Shergotty (meteorite)
The Shergotty meteorite (named after Sherghati) is the first example of the shergottite Martian meteorite family. It was a meteorite which fell to Earth at Sherghati, in the Gaya district, Bihar, India on 25 August 1865, and was retrieved by witnesses almost immediately. Radiometric dating indicates that it solidified from a volcanic magma about 4.1 billion years ago. It is composed mostly of pyroxene and is thought to have undergone preterrestrial aqueous alteration for several centuries. Certain features within its interior are suggestive of being remnants of biofilm and their associated microbial communities.

Achondrite
An achondrite is a stony meteorite that does not contain chondrules. It consists of material similar to terrestrial basalts or plutonic rocks and has been differentiated and reprocessed to a lesser or greater degree due to melting and recrystallization on or within meteorite parent bodies. As a result, achondrites have distinct textures and mineralogies indicative of igneous processes. Achondrites account for about 8% of meteorites overall, and the majority (about 2/3) of them belong to the HED clan, possibly originating from the crust of asteroid Vesta. Other types include Martian, Lunar, and several types thought to originate from as-yet unidentified asteroids. These groups have been determined on the basis of e.g. the Fe/ Mn chemical ratio and the 17O/18O oxygen isotope ratios, thought to be characteristic "fingerprints" for each parent body. Classification Achondrites are classified into the following groups:O. Richard Norton. The Cambridge encyclopedia of meteorites. UK, ...

1860s In Science
Year 186 ( CLXXXVI) was a common year starting on Saturday of the Julian calendar. At the time, it was known as the Year of the Consulship of Aurelius and Glabrio (or, less frequently, year 939 ''Ab urbe condita''). The denomination 186 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Martian Meteorites
A Martian meteorite is a rock that formed on Mars, was ejected from the planet by an impact event, and traversed interplanetary space before landing on Earth as a meteorite. , 277 meteorites had been classified as Martian, less than half a percent of the 72,000 meteorites that have been classified. The largest complete, uncut Martian meteorite, Taoudenni 002, was recovered in Mali in early 2021. It weighs 14.5 kilograms (32 pounds) and is on display at the Maine Mineral and Gem Museum. There are three groups of Martian meteorite: shergottites, nakhlites and chassignites, collectively known as SNC meteorites. Several other Martian meteorites are ungrouped. These meteorites are interpreted as Martian because they have elemental and isotopic compositions that are similar to rocks and atmospheric gases on Mars, which have been measured by orbiting spacecraft, surface landers and rovers. The term does not include meteorites found on Mars, such as Heat Shield Rock. Histo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meteorites Found In India
A meteorite is a rock that originated in outer space and has fallen to the surface of a planet or moon. When the original object enters the atmosphere, various factors such as friction, pressure, and chemical interactions with the atmospheric gases cause it to heat up and radiate energy. It then becomes a meteor and forms a fireball, also known as a shooting star; astronomers call the brightest examples "bolides". Once it settles on the larger body's surface, the meteor becomes a meteorite. Meteorites vary greatly in size. For geologists, a bolide is a meteorite large enough to create an impact crater. Meteorites that are recovered after being observed as they transit the atmosphere and impact Earth are called meteorite falls. All others are known as meteorite finds. Meteorites have traditionally been divided into three broad categories: stony meteorites that are rocks, mainly composed of silicate minerals; iron meteorites that are largely composed of ferronickel; and stony- ...

Yamato 000593
Yamato 000593 (or Y000593) is the second largest meteorite from Mars found on Earth. Studies suggest the Martian meteorite was formed about 1.3 billion years ago from a lava flow on Mars. An impact occurred on Mars about 11 million years ago and ejected the meteorite from the Martian surface into space. The meteorite landed on Earth in Antarctica about 50,000 years ago. The mass of the meteorite is and has been found to contain evidence of past water alteration. At a microscopic level, areas of the meteorite with spheres are rich in carbon compared to surrounding areas lacking such spheres. The carbon-rich spheres and the observed micro-tunnels may have been formed by biotic activity, according to NASA scientists. Discovery and naming The 41st Japanese Antarctic Research Expedition (JARE) found the meteorite in late December 2000 on the Yamato Glacier in the Queen Fabiola Mountains, Antarctica.

NWA 7034
Northwest Africa 7034 (NWA 7034, nicknamed Black Beauty) is a Martian meteorite.Associated Press (January 4, 2013)Mars meteorite 'Black Beauty' contains most water of any found on Earth, say scientists.''The Guardian'' It contains portions estimated to be 4.43 billion years old and contains the most water of any Martian meteorite found on Earth. Although it is from Mars it does not fit into any of the three SNC meteorite categories, and forms a new Martian meteorite group named "Martian (basaltic breccia)". It was purchased in Morocco and a slice of it was donated to the University of New Mexico by its American owner. Discovery and naming The meteorite was found by nomads in Rabt Sbayta, Ghredad Sabti region, Western Sahara, in the Sahara Desert in 2011, and was purchased in Morocco by a meteorite dealer who sold it to a collector in the United States, as Morocco does not have meteorite export control laws.

Nakhla Meteorite
Nakhla is a Martian meteorite which fell in Egypt in 1911. It was the first meteorite reported from Egypt, the first one to suggest signs of aqueous processes on Mars, and the prototype for Nakhlite type of meteorites. History The Nakhla meteorite fell to Earth on June 28, 1911, at approximately 09:00, in the Abu Hommos district, Alexandria Governorate, Khedivate of Egypt (now Abu Hummus, Beheira Governorate), in the area of the village of El Nakhla El Bahariya. The stones were collected near hamlets of Ezbet Abdalla Zeid, Ezbet Abdel Malek, Ezbet el Askar, and Ezbet Saber Mahdi."the meteoric stones of El Nakhla El Baharia (Egypt)" by G.T.Prior, Keeper of Minerals in the British Museum; read November 14, 1911, '' [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Meteorites On Mars
Martian rocks and outcrops have been studied ''in-situ'' by various landers and rovers. While many of the rocks identified on the Martian surface are similar to each other, some have been considered scientifically important or otherwise notable and have been subjected to more extensive study or public interest. Names for Mars rocks are largely unofficial designations used for ease of discussion purposes, as the International Astronomical Union's official Martian naming system declares that objects smaller than are not to be given official names. Because of this, some less significant rocks seen in photos returned by Mars rovers have been named more than once, and others have even had their names changed later due to conflicts or even matters of opinion among researchers. Often rocks are named after the children or family members of astronauts or NASA employees. The rocks at the landing site of the ''Sojourner'' rover were given names of cartoon characters. Among them were P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
