Two independent observations of Mars independently detected the presence of methane near the mouth of a generation on the surface of the red planet, a promising predictor of life because it is related to the activity on Earth.
According to the Daily Mail website, NASA's Kreuzi probe reportedly detected a "strong signal" of methane on June 15, 2013, but some experts questioned the reliability of the discovery.
However, the reanalysis of the data collected revealed an important task Mars Express(European Space Agency)ESA) Detected the presence of methane only one day after being detected by the Cryosti probe, confirming its real existence.
Marco Giorana, senior author of the study of the Institute of Astrophysics and Astronauts, said the data revealed a specific discovery of about 15% of the billionth of methane in the atmosphere, a day after the announcement of the rise of "Kreuzi". About 6 ppm.
Methane can be produced by both biological and geological processes. Its existence is not a definitive sign of life, but it can guide scientists in the right direction.
