Scientists: Mars suitable for life

The scientists, based on the results of observations of the Red Planet, came to the conclusion that Mars has the potential for the emergence and existence of life. Experts do not rule out the presence of water on Mars in the form of a concentrated brine. In similar circumstances in the world inhabited by bacteria.

The question of life on Mars was discussed at the beginning of February in Los Angeles at a scientific conference at the University of California. "We certainly can not deny the fact that Mars suitable for life" - said Alfred McEwen, leader of the research group at the University of Arizona.

Some experts believe that, in certain regions of Mars may be liquid water in the form of brine. In summer and spring on Mars may run off the steep slopes of salty streams. Total scientists have identified about 16 such sites with dark stripes - these are the slopes of the canyon Valles Marineris. However Astrobiology of pickles so far little is known. "The presence of salt water on Mars, perhaps not suitable for microbes," - said McEwan. Another proof of the possibility of life on this planet has perchlorate, found there in 2008. This chlorine-containing compound can serve as an energy source for bacteria and the food in the dark under conditions where photosynthesis is impossible.

At almost the same conditions on Earth - in the Atacama Desert and the arid valleys of Antarctica - live germs. In the valley of Antarctic organisms live in the depths of the rocks, while participating in the process of photosynthesis. On Mars, writes portal Space.com, may be something like that. As Atacama salt planet soil moisture may turn into a liquid absorbing it from the atmosphere. Scientists "have instructed" the rover Curiosity, which explores the suitability of life on Mars, "observe" the salt.
