For more than 200 days last mission of NASA, during which it was confirmed by the possibility of life on Mars. It is now known that Mars once was in many ways similar to the Earth, and it could be microorganisms.
New data were obtained after the first drilling produced rover Curiosity at the beginning of February. He drilled lying flat rock known as John Klein, veined - like the rocks in the river beds on Earth. The resulting powder was analyzed onboard laboratories CheMin and SAM, which are equipped with spectrometers, providing a very detailed report on the atomic composition of the rock.
Scientists have identified the presence of sulfur, nitrogen, hydrogen, oxygen, phosphorus and carbon - the key chemical ingredients of life in the dust produced by drilling.
These results suggest that this region of Mars was once a surprisingly livable.
"The fundamental question of this mission - how could inhabit life on Mars," - said Michael Meyer, lead researcher of the Mars Exploration Program. "From what we have learned to be a positive response."
"Clay minerals make up more than 20 percent of the sample taken," - said David Blake of NASA.
These clay minerals are the product of the reaction between the relatively fresh water with magmatic minerals.
