NASA scientists announced the discovery of traces of life.
X-ray of the Mars Rover Curiosity found in some parts of Mars high content of zinc, and Germany. In the Gale crater of these elements in ten, sometimes a hundred times more than the rest of the surface of Mars.
These substances the evidence of high hydrothermal activity, which once flowed on the planet. So say the authors of a study published in the journal of Geophysical Research: Planets. They believe that the similarity in chemical composition with earthly analogues proves the existence of life on Mars.
On Earth, these concentrations of substances are encountered in the extreme hydrothermal sources, and are favorable conditions for life of the simplest organisms. Scientists believe that a similar primitive creatures, germs and bacteria long ago, could dwell in the Gale crater. Age of a huge crater with a diameter of 150 kilometers, approximately 3.5 billion years. In the past the deepest part Galy was filled with water. In the center of the crater towering mount sharp, a height of 5.5 kilometers.
Near Gali 6 August 2012 landed the Rover Curiosity. NASA has sent its Mars program Mars Science Laboratory. Since then, the robot delivers on the ground information about the red planet.
