Microbes will become the main danger at colonization of Mars

Scientists consider that they can be more dangerous, than space radiation and influence of zero gravity. 

According to experts, at colonization of Mars not radiation and zero gravity, but microorganisms in the spaceship will become the main danger to future colonists. These conclusions were drawn after full studying of an experiment on imitation of the space flight Mars-500 made in 2010-2011 reports Guardian 

During the experiment made within 17 months, six volunteers were in the room about 180 meters imitating the spaceship. The main objective of scientists during passing of an experiment was to obtain information on dynamics of development of various microorganisms both in air, and on various surfaces. 

For obtaining results scientists selected about 20 places where presence of microorganisms during all "flight" was measured. In total 360 samples of a microflora which showed how during flight the quantity of bacteria and microbes and also their specific variety changed were taken. 

As showed results, throughout all experiment microbes continued to breed and their quantity didn't decrease. There were less various microorganisms, but in general their quantity didn't exceed norm. Experts consider what so occurred in many respects thanks to good cleaning and competent maintenance of an object. 

The general conclusion of a research is that the problems bound to decrease of the activity of immune system of crew and also the increased fastness of disease-producing bacteria to antibiotics in the time spent in space can become more serious danger at colonization of Mars, than the space radiation and reaction of an organism to stay mentioned more often at the lowered gravitation.
