And satellites have come to show that the dusty plains of Mars currently run rivers, and the hot and humid climate of the Red Planet provided an ideal climate for the reproduction of microbes, as is the case on Earth.
Scientists attributed the drought suffered by Mars to its loss from the atmosphere, since the water molecules dispersed very quickly.
Commenting on the study results, University of Arizona planetary chemistry expert Shane Stone said that water dries up easily when the atmosphere is damaged, according to the journal’s website. "Popular science" Scientific news specialist.
According to the study, it is possible that Mars was similar to planet Earth in the first days of the birth of our solar system, since both planets contain metallic cores molten with charge, and were responding to currents, forming magnetic barriers that protected them from solar winds, radiation and strong flares, which made water available in them. at first.
Unlike Earth, the core of Mars froze, causing the protective magnetic barrier to collapse, and the sun displaced much of the atmosphere, causing water to evaporate in space, three billion years ago. years, according to satellite data. "Muffin" Which has been orbiting the red planet since 2014.
And then added "Muffin" Samples of ions emitted from the water of Mars, surprised by Stone and his colleagues of scientists, that large amounts of water flew about 90 miles above the surface, to rise into the atmosphere, turning into oxygen that continues to decompose, and hydrogen moving away from the planet due to its light weight.
By analyzing how the water content in the upper atmosphere changed over time, the team also revealed two possibilities for why such moisture exists on Mars.
ورصد "Muffin" A climate that becomes very dry in winter and airless in summer, as well as dust storms that cause water consumption and high humidity in the atmosphere greater than almost twenty times, compared to the natural level.
Stone explained that the above factors played a fundamental role in the hardening of the core of Mars after a large increase in the temperature of the atmosphere, estimating that during the last billion years, heat and dust storms caused the planet to lose huge amounts of water that were sufficient throughout its history to flood the planet with an ocean depth that ranged from ten to ten. And hundreds of feet.
Stone ruled out that the earth will lose water at a very slow rate compared to what happened to the red planet, noting that we have between a thousand and two billion years until our water resources are depleted due to the increase in temperature at rates of hundreds of degrees.

According to the research, the results of which were published in the journal “Science Advances,” scientists have concluded that life on Mars thrived one day, but miles below the surface of the red planet, where geothermal heat was able to melt the thick layers of ice.
Using the simulation method to calculate the probability of the appearance of life on Mars, and the place that may have witnessed that life for the first time, the scientists indicated that 4 billion years ago the planet had a high geothermal activity , which caused the ice sheets to melt and may allow life to flourish.
According to the American research team, four billion years ago the sun was 25 percent dimmer than it is today, which means that the climate of Mars at that time should have frozen, but signs of minerals, products Chemicals and ancient river beds indicate that during that period water flowed towards the planet.
The scientists’ finding requires further investigation in the hopes of finding signs of microbial life miles below the surface of Mars through future explorations of the planet.
Researchers from the University of Arizona revealed earlier last month, in a study published in the scientific journal “Science,” that Mars was not dead as it is now, citing the reasons that led to its current situation.

After collecting “Maven” samples of ions emitted by the water on Mars, Stone and his fellow scientists were surprised that large amounts of water flew about 90 miles above the surface, to rise into the atmosphere, turning into oxygen that continues to decompose. , and hydrogen is moving away from the planet due to its light weight.

The “Maven” climate becomes very dry in winter and airless in summer, in addition to dust storms that cause water consumption and high humidity in the atmosphere greater than almost twenty times, compared to the normal level.
