The study of the chemical composition of the soil sample from Mars, made by American rover Curiosity, has shown that the conditions on the red planet in the distant past were suitable for sustaining life, similar to the one that exists today in the world.
According to information in the NASA small stone fragments was found the presence of clay minerals, which are likely to have been formed pH-neutral water. This discovery, scientists believe, once again proves the fact that Mars billions of years ago was dominated by favorable conditions for the emergence of life.
Curiosity mission began in August last year. During this period of time, managed to find ample evidence that in ancient times there was water on Mars. In February, the rover drilled into the surface of Mars, a small hole diameter of 1.6 cm and a depth of 6.4 cm, taking a sample of the solid soil. Later, the device stops responding, because he refused one of the computers. The rover immediately switched to a backup computer, but the elimination of technical problems with the main computer will require a few days, after which the rover will be able to return to normal operation.
