Opportunity” found traces of drinking water on Mars

Rovers continue to amaze earthlings their findings . On the eve of his ten-year stay on Mars rover “Opportunity” found on the edge of Endeavour crater sediments of clay, which confirm the discovery of his associates “Kyuriositi” actively exploring the other side of the Red Planet – in the ancient Mars had water and was suitable for life, the newspaper The Los Angeles Times.

Thus, these findings suggest the presence on Mars places where you could once primitive life forms exist. Researchers claim that all of their findings indicate deposits of clay on both sides of the planet.

Since early 2004, “Opportunity” on the surface of Mars looking for traces of water in the distant past. The chemical composition of minerals previously discovered Plateau Meridian pointed too high acidity of water that is not suitable for the development of life. However, analysis of soil samples from the crater Endeavour dramatically changed the picture: rover found traces of clay minerals that formed in water with low acidity and a neutral pH. According to Professor Steve Skvaersa from Cornell University and a leading researcher of the program NASA Mars Exploration Rovers, despite the close geographical location of clay and sulfate rocks, they were formed at different times.

This is one of the most ancient rocks found “Opportunity.” At the dawn of its history, Mars had fresh water, which then become acidic – Skvaers says.

Discovery, which became known from the journal Science, said Caltech geologist John Grottsinger:

These results show that in the past Mars had conditions for the emergence of life, but it does not mean that the planet was inhabited.

Available in “Opportunity” tools can not determine the exact age of the rock, but is estimated Skvaersa, clay deposits formed on Mars about 4 billion years ago, while the sulfate deposits appeared a few hundred million years. How the environment of the planet has undergone such rapid changes, remains a mystery . Work on the study of rocks in the crater Endeavour proceed with new force, said the researcher.

By the way, today “Opportunity” anniversary. Let’s congratulate him on this date!
