Was there ever life on Mars? Is There? meteorite from Mars renewed old disputes. International group, which includes scientists from EPFL, published an article in a scientific journal meteoritics and Planetary Sciences, where it is shown that the existence of life on Mars is more likely than previously thought.

Researchers from China, Japan and Germany performed a detailed analysis of ogranicheskih carbon footprints of the Martian meteorite and concluded that they are likely to have a biological origin. Scientists argue that carbon could also be to get into the cracks of rocks during their stay on Mars by seepage of fluids rich in organic matter.



meteorite called Tissint beaten Mars asteroid falling on its surface, landed in the Moroccan desert 18 July 2011 and was seen by several witnesses. The inspection found that the detection of extraterrestrial rock contains small cracks that are filled with substances containing carbon. Several research groups have reported on the organic nature of this component, but they are still arguing about the origin of carbon.

Chemical, microscopic and isotopic analyzes kinds of carbon material led investigators to several possible explanations. Scientists have identified characteristics that clearly excludes a terrestrial origin and showed that the carbonaceous material in the cracks appeared Tissinta before the object left Mars.

New data contradict the 2012 study published in the journal Science, where scientists have stated that there were traces of carbon due to high-temperature crystallization of magma.

The new findings are based on several properties of carbon meteorite, such as the ratio of carbon-13 and carbon-12. Ratio was significantly lower than the ratio of carbon-13 in CO2, contained in the atmosphere of Mars, which was measured and Phoenix rovers Curiosity earlier. The difference between the ratios perfectly consistent with observations on the Earth for the relationship between the fragment of coal and organic carbon in the atmosphere. The researchers note that organic matter can also be brought to Mars with primitive meteorites - carbonized chondrites, although such a scenario is unlikely, because the concentration of organic substances in such small meteorites.
