Sign of life. On Mars find more and more methane


Curiosity found the high content of gas which microorganisms can produce on the surface of the planet. The Curiosity mars rover found the high content of methane which is one of biomarkers in the atmosphere of Mars. The American New York Times newspaper writes that it can demonstrate existence of life on the Red planet. But in NASA remind, as before found methane in the Martian atmosphere which can be formed as a result of interaction between stones and water. But Curiosity have no tools to define a gas source. The correspondent.net tells details. Methane as a biomarker on Mars during measurements for June 19 of Curiosity found in the surface of Mars incredibly high level of release of methane - gas which on Earth is usually emitted by live organisms. In two days the scientists involved in a mars rover mission actively discussed news, without waiting for the official announcement of NASA, NYT wrote on June 22. Experts of a mission on Earth sent new instructions to the mars rover to obtain additional data, having cancelled earlier planned researches. It is expected that new data will be obtained on June 24, the newspaper noted. Record-holder mars rover. Opportunity died in a storm Planetologists considered that about four billion years ago Mars was warmer, more damp and more habitable planet. Now scientists consider a hypothesis that if on Mars once there was life, the microorganisms which remained after it could migrate deeply in a subsoil of the planet and remain there. On Earth the microbes called by metanogena live in places where it is not enough or at all there is no oxygen, and emit methane. But methane is formed also as a result of geothermal reactions which are not connected with biology in any way. For example emissions of volcanoes or reaction of water with ferriferous breeds, especially in warm places. Therefore, it is possible that the Martian methane millions of years is stored under the surface of the planet and sometimes gets to the atmosphere through cracks. For the first time methane on Mars found the device Mars Express 15 years ago. But then the scientific community doubted reliability of this find as the station worked to the limit, and many decided that it is a mistake. Curiosity of 2000 days on Mars: the main photos Later in 2013 Curiosity recorded the sudden sharp growth of level of methane in the atmosphere - to seven particles on one billion. In two months its concentration decreased. At the beginning of June scientists declared that the Curiosity mars rover made two important discoveries on the surface of the Red planet - found traces of ancient organic chemistry and proved that methane levels in its atmosphere strongly change at approach of winter and summer. "With these new opening Mars speaks to us to continue to look for signs of life. I am sure that our continuing and future missions prepare even more fascinating opening on the Red planet", - the head of department of scientific programs of NASA Thomas Zurbuchen says then. The researches Curiosity showed that concentration of methane grows in the atmosphere of Mars during summer and falls in time зи
