Mars is getting drier from even small sandstorms…

Scientists have discovered that small sandstorms, like large ones, dry out Mars .

AnthemSandstorms can spread all over the planet. Planetary scientists have longAnthemHe knows that these storms are behind the disappearance of water in . But large sandstorms alone are not enough to explain the extent of water loss on Mars.

Starting from here, scientists carried out a study using three spacecraft.

The study, published in the peer-reviewed scientific journal Nature Astronomy, looked at the regional and minor sandstorms that emerged on the Red Planet in January 2019 and February 2019.


Experts measured the amount of water vapor and ice in the lower atmosphere of the planet with the European Space Agency’s Trace Gas Orbiter spacecraft. NASA’s explorer Mars Reconnaissance Orbiter also supported these data by monitoring sand and temperature.

NASAHydrogen was also followed in the upper atmosphere with Mars Atmosphere and Volatile Evolution, another spacecraft of ‘s.

Scientists found that as the sandstorm intensifies, the temperature rises and water vapor near the surface rises. As the water vapor got closer to the ultraviolet rays from the sun, the hydrogen was seen to swell. This is a situation that occurs when water molecules dissociate.

In other words, regional and small sandstorms play with water vapor in the Martian atmosphere, preventing the passage of liquid water. These storms also trap water vapor high in the atmosphere. Thus, hydrogen atoms separate more easily from water molecules.
