US, WASHINGTON (ORDO NEWS) — Previously, scientists said that water on Mars exists in a state familiar to us, it only resembles a brine in its composition. Despite the obvious differences, experts hoped for the possibility of its application.
As it turned out, the Martian “pickle” is completely unsuitable for use. The main problem is that liquid from ice and atmospheric vapor can only exist for a few hours. Without water, Mars is unsuitable for human life.
The red planet, where the temperature averages + 40 ° C, has water reserves only in the form of ice. Also, a certain amount of liquid exists in the form of steam. Due to the low pressure (it is 160 times smaller than on Earth), the liquid immediately becomes vapor. The transition to a liquid state occurs only due to the salts contained in it.
Previously, scientists noticed light streams on the surface of the planet. They thought it was salt residues after evaporation of water. However, as it turned out later, it was sand.
Scientists from the Lunar and Planetary Institute in Houston have determined that the existence of salt solution is possible on 40% of the surface of the Red Planet. It is important to note here that it can remain in a stable state only in certain seasons and only for 0.04% of the earth’s year (about six hours).
The temperature in this case is ‒48 ° С, a person is not able to survive in such conditions.
Experts concluded that living organisms cannot exist in Mars. Perhaps some creatures lived 4 billion years ago when the climate was much milder. Then microorganisms that feed on the energy of inorganic compounds could inhabit.
