In the water on the red planet is five times more common isotope of hydrogen. Analysis of soil samples of the Red Planet, Curiosity combined unit on a place called "Stone Nest", has led to a number of discoveries. To begin experts found that the water found on Mars, Earth's heavier.
According to experts, it substantially more deuterium — an isotope of hydrogen, which has an extra neutron. In his Martian water five times. The researchers hope that the study of deuterium in the future will help to understand the evolution of the atmosphere and hydrosphere of Mars.
As reported by NASA, are also found in samples of the usual connection to the Earth: water vapor, carbon dioxide, oxygen, sulfur dioxide. In addition, Curisoity found on Mars traces of carbon, a key element of organic compounds. Finding may indicate that previously existed on the Red Planet forms of life, but scientists do not rush to conclusions.
"The fact that you found somewhere carbon, does not mean that there are life forms or suitable conditions for the emergence of life. If you have an organic carbon, but there is no water, the conditions for life are missing," — said lead California Institute of Technology Specialist John Grottsinger. Now, research is needed to continue to figure out which way these substances were on Mars, says RBC.
"We do not have conclusive evidence that organic matter found on the planet has a Martian origin. To assert this, you need to be absolutely sure that the compounds of carbon and chlorine — not part of a terrestrial organic matter, traces of which can be found in the solar system," — quoted scientist Paul Mahaffy Nanonewsnet.
Curiosity arrived at Mars on August 6. The purpose of the rover, which is a stand-alone chemical laboratory, is the search for traces of life on the planet, and the study of its geological history. It is expected that the unit will operate on the surface of the red planet for at least one Martian year (nearly two Earth years). The rover has already helped a number of important discoveries, send widescreen images of the Red Planet Mars, and even do a "check-in".
