Hydrogen and asteroids could have arisen on Mars life

Once upon a time on Mars could support life - this is evidenced by a new study by the NASA space agency. In it were involved information on the composition of Martian soil collected by the rover "Kyuriositi", and laboratory simulation of the ancient atmosphere of the Red Planet. During the experiment, scientists have found that Mars saturated hydrogen atmosphere can communicate with burns asteroids and engender a key element of life - nitrogen compounds or nitrates.

Reactive nitrogen is indeed an important part of life. Without them there can not be proteins, nucleic acids and other organic compounds that are essential for even the most simple organisms. It is these important elements of the machine have been found "Kyuriositi" while exploring the soil of the Martian crater Gale. Scientists raised the question: how did they get there?

To find the answer to this question, a team led by professor Rafael Navarro-Gonzalez conducted a laboratory experiment. To begin it early Mars atmosphere recreated by placing the mixture gas of hydrogen, nitrogen and carbon dioxide in the flask. The team then simulated the shock waves produced when asteroids hit the atmosphere - it pulses of infrared laser light used. Much to the surprise of scientists, then this reaction actually formed vital nitrates.

Investigators especially surprised that more hydrogen was contained in the simulated atmosphere, the more actively formed nitrates. It was logical, since hydrogen reduces the oxygen concentration which, in turn, is important for the formation of nitrate. According to planetary geochemist Jennifer Stern, the presence of hydrogen in the atmosphere of ancient Mars may have been important not only for life, but also to maintain a sufficient surface temperature of the planet and conserve water in liquid form.
