In danger of extinction MARS ROCKS Sculpt IN AFRICAPublished January 17, 2012 Associated Press-gang * Symbol * Email * Pot * Clarification * * * inShare11 * AP Photo/Darryl Pitt, Macovich CollectionScientists are confirming a recent and untreated invasion from Mars.Scientists are confirming a recent and untreated invasion from Mars: meteorite chunks from the red planet that sever in Morocco last July.This is completely the fifth time scientists identifiable encouraging chemically Martian meteorites that people witnessed as they sever. The fireball was spotted in the sky six months ago, but the rocks were not bare on the ground in North Africa until the end of December.This is an high-level and extraordinary break into for scientists not easy to restart about Mars' potential for life. So far, no NASA or Russian spacecraft has returned bits of Mars, so the completely Martian samples scientists can try are natives that give off just about in meteorite showers.Scientists and collectors of meteorites are hallucinating, and sooner than the rocks are in keeping big means in the function of they are among the rarest belongings on Soil, rarer shipshape than gold ingots.A special committee of meteorite experts, plus positive NASA scientists, encouraging the test have a disagreement Tuesday. They certified that 15 pounds (7 kilograms) of meteorite honest composed came from Mars. The main rock weighs senior than 2 pounds (1 kilogram).Astronomers stare millions of excitement ago whatever thing big destroyed stylish Mars and sent rocks hurtling fine hair the solar system. When a hope for skull fine hair space, one of natives rocks plunged fine hair Earth's air, splitting stylish minor pieces.Highest other Martian meteorite samples sat sharply on Soil for millions of excitement, or at the very least for decades, formerly they were bare, which makes them sullied among Soil resources and life. These new rocks, even though peaceful I imagine corrupted in the function of they identifiable been on Soil for months, are purer.The last time a Martian meteorite sever and was found lovable was in 1962. All the predictable Martian rocks on Soil add up to under than 240 pounds (110 kilograms).The new samples were scooped up by dealers from natives who found them. String formerly the wise authorize, scientists at NASA, museums and universities scrambled to buy or trade these meteorites."It's a free tape from Mars. That's what these are, hinder you identifiable to pay the dealers for it," made-up Educational of Alberta meteorite high-class Chris Group, who heads the committee that certified the discovery.He sooner than has bought a block of meteorite and made-up he was happy minimally to hold it, profession the rock "authentic pompous."One of the deep decisions the scientists finished Tuesday was to connect these rocks lawfully to the spicy initiative witnessed by people and captured on video last summer. The announcement and the baptism ceremony of these meteorites -- called Tissint -- came from the Conglomerate Partaker for Meteoritics and Planetary Science, which is the wise group of 950 scientists that confirms and names meteorites.Meteorite vendor Darryl Pitt, who sold a block to Group, made-up he charges 11,000 to 22,500 an ounce and has sold most of his excavation sooner than. At that excise, the new Martian rock charge about 10 time senior than gold ingots."It's technically a hoot," Group made-up. "These are authentic appealing specimens. It's a untreated type, so lovable and aesthetically delightful."Specific of the world's top experts in meteorites, plus natives who work for NASA, told The Associated Press-gang that they were sure this was a citation of Mars. Tony Irving of the Educational of Washington is the scientist who did the mechanical check on the rocks and made-up offer is no apprehension that they are from the red planet.Scientists can tell next meteorites are from Mars in the function of they know what the Martian air is finished of, thanks to a lot of probes sent offer. The chemical signature of the rocks and the Martian air appropriate, Irving made-up. Changed plan is that in the function of planets whim Mars are senior organically energetic, its rocks hold on to to be radically younger -- millions of excitement old pretty of hundreds of millions or senior -- than natives from the moon or asteroids.Highest of the Martian rocks on Soil identifiable been sharply for centuries or longer and identifiable been found in Antarctica or the place. They form so identical to gloomy Soil rocks that if they sever in other sitting room, such as Maryland, they would union seemly in and never be bare, Irving made-up.Jeff Grossman, a NASA scientist who is the Meteoritical Society's database editor, made-up offer is a greater chances of discovery "whatever thing succulent" from Mars on these rocks in the function of they sever so honest. Even so, six months is a hope for time for Worldly tinge to keep going beginning, he made-up.Group made-up the first thing he would do among the rocks would be to rinse them among solvents to try to get rid of of time tinge and see what carbon-based compounds are missing.A Martian meteorite that was dug in in Antarctica finished news in 1996. NASA scientists theorized that the rock, found in 1984, showed cipher of traces of life from Mars, fossils of what seemed to be lifelong forms. String the Old Station finished an announcement about it as the first sign of life top of Soil. Animation of appraise the same as plus identifiable led radically of the astronomy world to finish that offer was not satisfactory evidence to support the cleave to.While predictable Martian meteorite torrent turn up completely once completely 50 excitement or so -- 1815 in France, 1865 in India, 1911 in Egypt and 1962 in Nigeria -- this is a once-in-a-career or shipshape one-in-a-lifetime thing."It's very lovable. It's completely advantageous for that validation," made-up Carl Agee, manager of the Establish of Meteoritics and keeper at the Educational of New Mexico. "For one who knows their Martian, this is a beauty. It's charming."Shed light on more: http://www.foxnews.com/scitech/2012/01/17/rare-mars-rocks-fell-in-africa-last-july/#ixzz1jp8zZnlt
