The probability of a huge lake under ice near the South Pole on Mars, where such a volume of liquid water, a prerequisite for the development of life, has never been found until Now, today announced an international group of astronomers. The lake, located under a layer of Martian ice, at a depth of about 1.5 kilometers, has a diameter of about 20 kilometers and the shape of a rounded triangle
Although the water temperature is below -10 degrees Celsius, the water can be in liquid form. Magnesium, calcium and sodium known to exist on the rocks of Mars could dissolve in water to form brine. With the pressure created by the ice, it would lower the melting point by allowing the lake to remain wet, as is the case on Earth
There is a lot of work to be done to confirm that the lake actually has a liquid in liquid form, and there is no evidence that the lake is alive. "The arrival (on the lake) as well as obtaining the final proof that it's a good lake will not be an easy task." You will have to drive a robot that can drill 1.5 kilometers of ice. The technological developments that are currently lacking will be necessary, "said Roberto Orosei, chief scientist at the Institute of Radioastronomy in Italy, who badyzed the data.
The published results reign again in the long debate over the question of whether there is a large volume of wet water on Mars and creates hope for the presence of other waters, even life, on the red planet, according to an article published in the ### 39, American Science Review
"This is an incredible result which makes us think that the presence of water on Mars is not just a temporary flow like the previous discoveries l '. have shown, but a permanent mbad of water that creates living conditions over a prolonged period, "comments Alan Dafi, an badistant professor at Shaunberne University. (19659002) The Mars planet is frozen, desolate and anhydrous but previously hot and humid and has a large amount of water in liquid form and lakes before at least 3.6 for millions of years
