Revealing life on Mars will be much more difficult

Выявить жизнь на Марсе будет гораздо сложнее Recent studies by scientists from the School of Physics and Astronomy at the University of Edinburgh have shown that finding life on the red planet will be much harder than previously thought. One of the primary life forms, hay bacillus (Bacillus subtilis), dies on contact with perchlorates (perchloric acid salts, found in large quantities on Mars). Prior to obtaining these studies, experts believed that perchlorates act only at high temperatures, and low temperatures of Mars will not allow harm to living organisms. The studies presented show that, to activate perchlorates, the sufficiently high ultraviolet radiation present on Mars, where the local atmosphere is not able to protect the surface of the planet from harmful effects. Bacteria of hay bacillus die in a matter of minutes. Project managers say that to reveal life on Mars, more effort will be required and it will be possible to detect it only on surface sections protected from ultraviolet radiation or under layers of soil. Scientists also noted that perchlorates are not deadly for absolutely all forms of living life. These chemical compounds were discovered on Mars in 2008, when the Phoenix spacecraft explored stripes on the planet in search of water, which is essential for the origin of life.
