The Mars model appreciated the possibility of extraterrestrial life: it can be in the salt solutions of the planet

The Mars model appreciated the possibility of extraterrestrial life

A unique model of living conditions on Mars has helped American scientists estimate the potential search for life forms on the Red Planet. They examined the possibility of the presence of life in liquid salt solutions and concluded that this was not possible. Climatologists at the Southwestern Research Institute have created a model of the surface of Mars to find out whether hydrated salts or brines on the surface of the Red Planet can contain life forms.

The results show that this is hardly possible. The salty water of Mars is too cold for life to survive. The salty foci that exist on the Mars are on the Earth. But unlike the ones on the Earth, the development of life on Martians is impossible. This is due to extremely low temperatures on the planet, as well as very dry conditions.


If a drop of liquid water hits the surface, it instantly freezes or evaporates, or dissolves in salt, forming a salt brine. It has a lower freezing point and therefore evaporates from the surface of the Mars much more slowly. Salt on the Mars is in many places, and it forms layers of salt brines.

Astronomers have studied the territories where such foci can form, suggesting that they could be the habitat of living organisms. The created model also helped to predict when and for how long salt formations can be in a stable state on the surface of the Mars.

To reach a certain humidity on the planet, the Mars needs lower temperatures, up to minus 55 degrees. But scientists know that even the most extreme life form that is possible on the Earth has its limits. They calculated that the formation of brine can lead to the formation of a certain amount of clean water - up to two percent in one Martian year.


At the same time, low temperatures are maintained, and there is not enough clean water to support life. These factors exclude the presence of life in salt solutions in precisely the forms that science on the Earth knows.
