Water on Mars was heavy earth Bashny.Net

analysis of samples of soil of the Red Planet, Curiosity combined unit on a place called "The Stone Nest", has led to a number of discoveries. For a start, experts found out that the water found on Mars, heavier zemnoy.

According to experts, it is much larger deuterium - an isotope of hydrogen that has an extra neutron. The Martian water, it is five times more. The researchers hope that the study of the deuterium in the future will help to understand the evolution of the atmosphere and hydrosphere Marsa.

As reported by NASA, the samples are also found familiar to Earth Connection: water vapor, carbon dioxide, oxygen, sulfur dioxide. In addition, Curisoity found on Mars traces of carbon, a key element of organic soedineniy.

The find could mean that previously existed on the Red Planet forms of life, but scientists are not in a hurry to draw conclusions prematurely.
"The fact that you found somewhere carbon, does not mean that there are life forms and suitable conditions for life. If you have an organic carbon, but there is no water, the living conditions will be absent ", - said a leading specialist Caltech John Grottsinger. Now, research is needed to continue to determine the way in which these substances are put on Mars.

"We do not have conclusive evidence that discovered the planet has organics Martian origin. To assert this, you need to be absolutely sure that these compounds of carbon and chlorine - are not part of the Earth's organic, traces of which can be found in the solar system "- quoted a scientist Paul Mahaffy Nanonewsnet.
