Astrophysics from the Institute of space Sciences (Blue Marble Space Institute of Science) found that one of the reasons for the loss of the Martian atmosphere was interstellar clouds, according to the portal Space.com. Report on the study published in the scientific journal Monthly Notices of the Royal Astronomical Society, informs “the Russian newspaper”.
Scientists report that they have found another important reason for the loss of Mars atmosphere. They analyzed data obtained with the spacecraft MAVEN (Mars Atmosphere and Volatile EvolutioN Mission).
Previously, it was found that outgoing from the Sun charged particles expelled from the Martian atmosphere, hydrogen molecules, causing them evaporate into space. A new study has shown that the Red planet was also lost to the atmosphere in passing through interstellar clouds.
Data machine MAVEN show that ionized radiation from the Sun, played a key role in the process of loss of the atmosphere of Mars, ” says the study’s lead author Dimitra Atri. – But the role of the interstellar clouds in the process was very important. From time to time we move through a vast and dense cloud of gas and dust. This event lasts about one million years.”
Researchers have estimated that Mars is happening, at least 135 times. And every time the Red planet experienced the same process: the gas and dust in an interstellar cloud encountered by the solar wind and created a powerful shock wave. It accelerated charged particles. Each passage through an interstellar cloud Mars lost 0.5 percent of its atmosphere.
