“Exomars” probe detects traces of chloric acid in the atmosphere of Mars, today Tuesday, October 6, 2020 06:04 pm

Russian spectrometers carried by the European “Exomars” probe into the atmosphere of Mars have recorded traces of chloric acid.

Scientists assume that this acid appeared as a result of the interaction between salt, water and sunlight particles in the upper layers of the Martian atmosphere.

The chief expert in the planetary physics department of the Russian Institute for Space Studies, Alexander Trukimovsky, said in a speech delivered at the 11th Moscow Conference on the Study of the Solar System that the search for chloric acid was one of the main tasks assigned to the joint European-Russian “Exomars” mission.

It is reported that the chloric acid vapor is present in the Earth’s atmosphere, which it enters as a result of the eruption of volcanoes. Studies conducted by the American roofers showed the presence of large quantities of chlorine compounds in the soil of Mars. Traces of chloric acid, however, were first detected in the Martian atmosphere.

It is worth noting that the European probe of the European-Russian “Exomars” mission has been studying the Martian atmosphere for 3 years in search of methane in order to assess its density in the atmosphere and discover potential sources of this gas.

Trukimovsky and his Russian colleagues have discovered for the first time chloric acid vapor in the Martian atmosphere using spectrometers. Russian planetary scientists consider that the source of this vapor is large quantities of chlorine compounds, oxygen and other chemical elements that are contained in the Martian soil and are generated by various geological processes that occur in the planet’s interior.

Russian scientists assumed that the chloric acid vapor ascends into the layers of the Martian atmosphere with ultrafine particles produced by dust storms that occur on the planet’s surface.

Russian member of the “Exomars” team, Alexei Malakhov, said in a speech at the conference that Russian scientists also discovered large quantities of water on the slopes of Olympus and other volcanoes on Mars. He explained that, according to planetary scientists, volcanoes prevent water from being emitted into cosmic space.

And the Russian scientist recalled that the Russian space platform will land in 2022 in an equatorial area near the volcano Olympus.
