	Martian Meteorite Linked to Rock at Meridiani
		This meteorite, a basalt lava rock nearly indistinguishable from many Earth rocks, provided the first strong proof that meteorites could come from Mars.
		(The vertical stripes are saw marks.) The fl patches in the rock are melted rock, or glass, formed when a large meteorite hit Mars near the rock.
		The meteorite impact probably threw this rock, dubbed "EETA79001," off Mars and toward Antarctica on Earth.

	NAI News Article: Taking the Temperature of a Martian Meteorite (Site not responding. Last check: 2007-10-09)
		Microscopic shapes in the carbonate globules of ALH84001 resemble fossil bacteria on Earth, and the meteorite seems to have the same microscopic mineral grains that are produced by bacteria.
		They reasoned that, although no living martian organisms were found in ALH84001, if ALH84001 had made it to Earth without ever getting super-hot, it was conceivable that, billions of years ago, another similar martian meteorite could have transported life from Mars to Earth.
		Meteorite ALH84001 believed to have originated on Mars, was found in the Allan Hills region of Antarctica.

	Geoscience - Meteors and meteorites - Martian meteorites
		It is believed that all of the Martian meteorites landed on Earth as fragments from large meteorites or asteroids that crashed into Mars between 180 and 1300 million years ago.
		All Martian meteorites are formed from igneous rocks, so they must have formed on an earth-like planet or one of its moons.
		It is an achondrite (shergottite) stony meteorite, mainly composed of the minerals olivine and plagioclase, and is believed to have originated as a basalt on the planet Mars.

	French scientists find rare Martian meteorite (Site not responding. Last check: 2007-10-09)
		Scientists said they hoped the discovery of the meteorites would help clarify the processes that produced magmas on Mars and perhaps make it possible "to estimate the quantity of fluids (and therefore water) released by volcanic activity on the planet".
		SNC meteorites are extremely rare -- fewer than 20 confirmed examples have been discovered -- and are believed to all come from the same body of rock.
		The meteorite discovered by the French-led team in Morocco is officially called the North-West 1950 but has been nicknamed the Jules Verne, after the French author, by the scientists.

	New Martian Meteorite :: Astrobiology Magazine ::
		Discovery of this meteorite occurred during the second full field season of a cooperative effort funded by NASA and supported by the National Science Foundation (NSF) to enhance recovery of rare meteorite types in Antarctica, in the hopes new martian samples would be found.
		The new specimen is the seventh recognized member of a group of martian meteorites called the nakhlites, named after the first known specimen that fell in Nakhla, Egypt, in 1911.
		Like the other martian meteorites, MIL 03346 is a piece of the red planet that can be studied in detail in the laboratory, providing a critical "reality check" for use in interpreting the wealth of images and data being returned by the spacecraft currently exploring Mars.

	PSR Discoveries:Hot Idea: Martian meteorite EETA79001
		The young ages of the SNC meteorites led some scientists to suggest that the SNC had to come from a body that was large enough to remain geologically active until at least 1.3 billion years ago, and perhaps as recently as 180 million years ago.
		The assumption was that the meteorites were blasted off their planet of origin by a large impact.
		They argued that there was no way of getting a meteorite off Mars without melting the rock, and there was no evidence for impact melting in the Martian meteorites, although the effects of impact short of melting were evident in many SNC meteorites.

	A Martian Meteorite
		This meteorite, called EETA 79001, was found on the ice in Antarctica, and is quite likely from Mars.
		The meteorite is partly covered by a fl glassy layer, the fusion crust.
		This meteorite is quite likely from Mars because it contains a small amount of gas that is chemically identical to the Martian atmosphere.

	Martian meteorite
		Allan Hills 84001 -- a meteorite the size of a potato -- remains in the center of a spirited controversy about the possibility of life on Mars.
		The meteorite was found in the 1980s in Antarctica by the National Science Foundation's Antarctic Search for Meteorite Program (ANSMET), headed by Harvey with headquarters at CWRU.
		Harvey, who is currently on his annual expedition to Antarctica to collect meteorites, commented before leaving November 21 that the Johnson-Stanford team has always argued that they had used different techniques to study the meteorite.

	Meteorite Yields Evidence of Primitive Life on Early Mars
		The NASA-funded team found the first organic molecules thought to be of Martian origin; several mineral features characteristic of biological activity; and possible microscopic fossils of primitive, bacteria-like organisms inside of an ancient Martian rock that fell to Earth as a meteorite.
		The rock is believed to have originated underneath the Martian surface and to have been extensively fractured by impacts as meteorites bombarded the planets in the early inner solar system.
		Although past studies of this meteorite and others of Martian origin failed to detect evidence of past life, they were generally performed using lower levels of magnification, without the benefit of the technology used in this research.

		A Mars meteorite is a meteorite that has landed on Earth and originated from Mars.
		In March 2004, it was suggested that the unique Kaidun meteorite landed on March 12, 1980 in Yemen, may have originated on the Martian moon of Phobos.
		The majority of SNC meteorites are quite young by geologic standards and seem to imply that volcanic activity was present on Mars only a few hundred million years ago.

	Martian Meteorite Summary (Site not responding. Last check: 2007-10-09)
		All of the martian meteorites are igneous rocks formed by crystallization of cooling magma in Mars' crust.
		Martian meteorites have many similarities to HED achondrites which are basaltic eucrites, cumulate diogenites and howardites formed by mixing the two types.
		Martian meteorites were grouped with HED meteorites until their young crystallization ages and distinct oxygen isotope trend defined them as a distinct SNC group.

	Science Explained, explains the controversial Martian "Fossils".
		However, the chemists who identified these molecules in the Martian meteorite were concerned that the PAHs they found may have been introduced to the rock AFTER it fell to Earth.
		The PAHs that had been on the surface of the meteorite were probably burned off as the rock passed through space and the Earth's atmosphere.
		The carbonate chemistry of the Martian meteorites is not the final evidence.

	Re: how do we know the meteorite was from Mars that showed life signs?
		By analyzing the abundance of isotopes of certain elements found within the meteor and in silica inclusions within the meteorite and comparing these abundances to the same data collected on Mars and on Earth, the origin of the meteorite can be determined.
		Analyses of the gases in glassy inclusions in the SNC meteorites EET79001 by Bogard and Johnson [
		This remarkable agreement is one of the strongest arguments that the SNC meteorites represent samples from Mars.

	Caltech Press Release, 10/26/2000, Dr. Joseph Kirschvink
		But new research on the celebrated Martian meteorite ALH84001 shows that the rock never got hotter than 105 degrees Fahrenheit during its journey from the Red Planet to Earth, even during the impact that ejected it from Mars, or while plunging through Earth's atmosphere before landing on Antarctic ice thousands of years ago.
		The meteorite ALH84001 has been the focus of numerous scientific studies in the last few years because some scientists think there is tantalizing evidence of fossilized life within the rock.
		Though the study does not directly address the issue of life in meteorites, the authors say the results eliminate a major objection to the panspermia theory--that any life form reaching Earth by meteorite would have been heat-sterilized during the violent ejection of the rock from its parent planet, or entry into the atmosphere.

		This rock is a Mars meteorite that was found in Antarctica in 1984, and it is called by the name ALH84001.
		He realized this particular meteorite had been misclassified when it was originally identified, and that it was actually the latest member of the exclusive clan of meteorites that hail from Mars.
		In stark contrast, the Martian globules are composed primarily of magnesium with lesser amounts of iron, calcium, and manganese.

	The Martian Meteorites
		Gases trapped in the rocks match those of the Martian atmosphere; and the rock's oxygen isotopic ratios, which are unlike other meteorites or any Earth rock, match the ratios found on Mars by the Viking landers.
		Most of the Martian meteorites are less than 1.5 billion years old, and they were formed after the time when Mars had liquid water.
		Evidence for fossil life in this meteorite was found in tiny carbonate globules deposited in cracks in the rock.

		But several facts support a Martian origin, including the deep embedding of the crystals in the carbonate material of the meteorite and the preference of the magnetite-producing bacteria for low-oxygen environments, making it unlikely that such bacteria would live where the meteorite was found.
		This meteorite -- called the Allan Hills meteorite after the Antarctic ice sheet where it was found -- is the same one that caused a stir in 1996 by providing the first potential evidence of bacteria-like life on Mars.
		The Martian dynamo is extinct, and its magnetic fields are "fossil" remnants of its ancient, global magnetic field.

	Unexplained Mysteries :: Evidence of life in Martian meteorite ?
		A new study of a meteorite that originated from Mars has revealed a series of microscopic tunnels that are similar in size, shape and distribution to tracks left on Earth rocks by feeding bacteria.
		And though researchers were unable to extract DNA from the Martian rocks, the finding nonetheless adds intrigue to the search for life beyond Earth.
		The second possibility is that the tunnels on Martian rocks are indeed biological in nature, but the conditions are such on Mars that the DNA was not preserved." More than 30 meteorites that originated on Mars have been identified.
