The end of the dispute over the gas methane of Martian life


Marx Express confirms first day of curiosity detection

Mars ends the methane controversy

Several studies have found that methane (CH4), which may be a sign of life on a red planet, Mars, has been found several times but has always been undeclared and controversial.

All rely solely on a single die and have been unable to get rid of complaints about measurements or device errors.

But Mars Exploration Rover, Curiosity, discovered Mars Exploration (Mars Express) of the European Space Agency (ESA), which orbits Mars when it detected methane on June 15, 2013, also showed signs of methane capture in it area at different times of the day.

Even after the meteoric claims that were inside the device, measurements of methane were first verified and the end of the controversy surrounding the existence of methane was taken.

A research team led by Dr. Marco Ziurana of the National Institute of Astrophysics of the National Institute of Astrophysical Research of Italy (NASA) published an article on the methane levels measured by the Plan Fourier (PFS) spectrometer. Published in the current issue of Nature Geoscience.

The methane level that Mars Express captured on Gayle Crater on June 16, 2013 is 15.5 ppb (1 ppb = 0.001 ppm).

Mars ends the methane controversy

The day before, the methane measured by Curious City on the surface of the Gale crater was 7bbp.

Before that, it was only 0.7 ppb, which was about 10 times higher, and fell to 1bbp in January the following year.

Methane is known primarily for microorganisms and life activities.

Although it is produced by geological activity, regardless of life activity, it is known that 90-95% of atmospheric methane, which is 1,800 ppb on earth, comes out of life activity or corruption.

Because of this, methane was considered as an indicator of life, and the controversy followed each time a methane methane detection study was published.

Three teams reported the detection of methane in the atmosphere of Mars before the procession detected methane.

The two teams produced these results based on Earth observations, while the other team used the Marx Express measurement data but did not gain confidence because the measurements were all close to the limits that the instrument could measure.

Dr. Jiurana's team, in addition to confirming the results of methionine curiosity detection in this study, tracked the methane source by dividing the Gale craters by 250 km2.

As a result, the researchers analyzed that the methane must be released into the atmosphere from the methane ice sheet, about 480 km east of Gale Crater.

"Methane is important as an indicator of the presence of microorganisms," says Ziurana. "It is not direct evidence of the existence of life forms, but it increases the likelihood of living things that methane may be the source of carbon and energy for some microorganisms," he said.

He added that if new studies confirm that methane is present, future incineration teams on Mars will be able to get fuel and propellants.
