Scientists have found the cause of the dust storms on Mars


Ученые нашли причину появления пылевой бури на МарсеScientists believe that dust storms contributed to the release of water into space.

An international group of scientists analyzed data from Orbiter for the study of small atmospheric constituents, which he recorded during last year’s dust storm on Mars, and suggested that such disasters could cause drying of the planet.

The Orbiter for the study of small atmospheric components (TGO) – a spacecraft designed to study trace gases in the Martian atmosphere. He became part of a large-scale program of the European space Agency (ESA) and the Russian state Corporation Roscosmos – ExoMars.

In the summer of 2018 on Mars began dust storm, which covered almost the entire planet. Her NASA lost contact with Mars Rover Opportunity. TGO watched the cataclysm from orbit. He investigated the atmosphere to determine how the dust storm is absorbing sunlight. Now a team of scientists from Spain, Italy, Poland and other countries have used these data to follow the behavior of water during a hurricane.

They found that before the dust storm, the prevalence of semi-heavy water (in which only one hydrogen atom is substituted with deuterium) at altitudes above 40 km was decreased to below detectable. This decrease coincided with the appearance of ice clouds. During the storm, they observed an increased content of water and heavy water in vapor form at an altitude of between 40 and 80 kilometers. The authors attributed this distribution with increasing temperature. The dust absorbs heat, leading to warming of the atmosphere and prevent the formation of ice clouds.

First of all, the authors want to find out how dust storms are formed and what causes for their occurrence. Supervision, especially at the moment of conception, could give new clues. Meanwhile, scientists say that such disasters are “fanning” the atmosphere, facilitating gas access to the space, including steam. Perhaps because of such storms Mars has become so inhospitable to what is today.

Recently, the National Aeronautics and space administration published on its website footage of the solar Eclipse on Mars, which captured the Curiosity Rover.
