According to the American newspaper, the mission's scientists "captured" in the middle of last week a signal in rover measurements, which show high concentrations of methane in the Martian atmosphere. On Earth, methane is also produced by living things, but also by non-biological geochemical processes.
Scientists are trying to get more information to come up with safer conclusions before making a statement. To this end, they have sent new orders to Curiosity to make new measurements, and their new results are expected on Earth today.
So far, NASA has said it is & # 39; Preliminary results & # 39; and that "Curiosity's scientific team will continue to analyze the data before confirming the findings." According to information, the methane count is 21 parts per billion (ppb).
On Earth there are bacteria that produce methane both in the subsoil and in the digestive system of certain animals. If there is really too much methane on Mars, this or it will have to be produced by some current source (white or dwarf) or will be old methane (uninhabited or of living origin) imprisoned many millions of years ago and is now gradually liberated by cracks in the Martian surface.
The first detection of methane on Mars was made about 15 years ago by the Martian Express Martian Express of the European Space Agency. In 2013, Curiosity detected methane on Mars, which was repeated. Found, shows methane seasonal fluctuations for an unknown reason. It is indicative that the newest European maritime satellite, the Trace Gas Orbiter (TGO), which has more sensitive instruments, did not detect any methane in 2018, which created a mystery and a conundrum around the gas ghost.
