MOSCOW, December 14 - RIA Novosti. Curiosity rover found on the surface of Mars Forest - the most important element for life, which is a key part of many protein molecules and vital for the synthesis of DNA and RNA, the scientists said, speaking at the annual conference of the American Geophysical Union in San Francisco.
"No other mission had not found a boron traces on Mars. If boron, which we found in the Martian deposits of gypsum, similar to those compounds of the substance that is on the earth, we can say that the water in which these deposits were formed , was neutral on its chemical properties and quite warm -. from zero to 60 degrees Celsius in other words, they were suitable for life ", - said Patrick Gasda (Patrick Gasda) National laboratory in Los Alamos (United States).
One of boron and molybdenum sources, as shown by the study of Martian meteorites in 2013, could serve as Mars. In its atmosphere, according to Steven Benner (Steve Benner), xenobiology known, contain a sufficient quantity of oxygen required for the oxidation of these elements and their dissolution in water.
The problem, says Gasda, lies in the fact that until today no trace of boron or molybdenum on Mars could not find that cast a shadow on the hypothesis Benner. Scientific Curiosity rover team were able to confirm its "boric" half. The fourth rover NASA has found traces of elements in rocks that are studied during the last two parking lots in villages on the slopes of Mount Sharp, received the names and Udam Sebino.
It turned out that the open cobble, named catastate consists of plaster, inside which there are layers of boron salts contained in it in high enough concentrations. Later, when the rover continued the ascent to the summit of Mount Sharp, scientists began finding even more noticeable deposits of this "life element".
As suggested by researchers, they could be formed in two ways - for drying of large volumes of water, just as there are boron deposits in the world, or the result of chemical interactions Mars soil and water streams passing through them in the past.
"This basin of sedimentary rocks is a real chemical reactor elements in it were reversed, new minerals appeared and disappeared old, electrons are continually redistributed and there were other processes that support life on Earth." - Says planetary scientist.
According to him, these reactions, according to the thickness of the layers of rock containing boron and other elements could continue on Mars hundreds of millions of years. This significantly increases our chances of finding life on the surface of the red planet, the scientist concludes.
