By using the simulation method to calculate the probability of the emergence 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 led to the melting of ice sheets, and perhaps allowed life to flourish.
According to the American research team, it was the sun Four billion years ago, 25 percent less bright than it is today, which means that the Martian climate at the time should have been frozen. Minerals Chemicals and ancient river beds indicate that during this period water was flowing into the planet.
The scientists’ conclusion requires more Research Hoping to find signs of microbial life miles deep under the surface of Mars on future explorations of the planet.
Researchers at the University of Arizona revealed that earlier last month, in a study published in a journal "Science" Scientific, that Mars was not dead as it is now, indicating the reasons that led him to his current situation.
And she was satellite I came up with evidence that the dusty plains of Mars were currently running rivers, and that the warm and humid climate of the Red Planet provided an ideal climate for microbes to breed, as is the case with Earth.
Scientists attributed the drought suffered by Mars to its loss To the atmosphere, As the water molecules were scattered very quickly.
Commenting on the results of the study, the expert in planetary chemistry at the University of Arizona, Shane Stone, said that the water dries up easily when the atmosphere is damaged, according to the magazine website. "Popular Science" Specialist in scientific news.
According to the study, it is possible that Mars was similar to the planet Earth in the early days of the birth of our solar system, as both planets contain molten metallic cores with a charge, and they were responding to the currents, forming magnetic barriers that protected them from solar winds, radiation and strong flares, which made water available on them. at beginning.
Unlike Earth, the core of Mars froze, which led to the collapse of the protective magnetic barrier, and the sun displaced a large part of the atmosphere, so water evaporated in space, three billion years ago, 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 quantities of water were flying about 90 miles above the surface, to rise into the atmosphere, turning into oxygen that continues to decompose, and hydrogen 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 as to why such moisture exists on Mars.
ورصد "Muffin" A climate that becomes very dry in winter and no air in summer, in addition to dust storms that cause water consumption and high humidity in the upper atmosphere to nearly twenty times, compared to the natural level.
Stone explained that the previous factors played a pivotal role in the hardening of the core of Mars after a great increase in the temperature of the atmosphere, estimating that over the past billion years, heat and dust storms caused the planet to lose huge quantities of water that were sufficient throughout its history to flood the planet with an ocean depth ranging between tens 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, pointing out that we have between one billion and two billion years until our water resources are depleted due to the rise 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 It thrived someday, but miles below the surface The red planetThe geothermal heat was able to melt the thick ice sheets.

Unlike Earth, the core of Mars froze, which led to the collapse of the protective magnetic barrier, and the sun removed a large part of the atmosphere, so water evaporated in space, three billion years ago, according to data from the “MAVEN” satellite, which has been orbiting the red planet since 2014.
After collecting “Maven” samples of ions emitted from the water of Mars, Stone and his colleagues of scientists were surprised that large quantities of water were flying 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 no air in summer, in addition to dust storms that cause water consumption and high humidity in the upper atmosphere to nearly twenty times, compared to the normal level.
Stone explained that the previous factors played a pivotal role in the hardening of the core of Mars after a great increase in the temperature of the atmosphere, estimating that over the past billion years, heat and dust storms caused the planet to lose huge quantities of water that were sufficient throughout its history to flood the planet with an ocean depth ranging between tens And hundreds of feet.
