Water existed on Mars billions of years before scientists about the phenomenon Consider Possible

The new evidence provided by NASA spacecraft, Mars Reconnaissance Orbiter (MRO) have revealed that the entire network of lakes and streams fed by melted snow on Mars existed much earlier than it imagined researchers.

Based on the new images taken on ancient region, north of Mars, researchers said there was a considerable amount of water ,, '' with about a billion years before the '' wet Age '' of the red planet to end. This indicates that the planet was suitable for microbial life for much longer than estimated by the researchers.

,, I discovered valleys carrying water to lake basins, '' said a team member, Sharon Wilson, of the Smithsonian Intitutului. ,, Some of the lakes filled pools indicates that there was a considerable amount of water in those times, '' she added.

Wilson and his team analyzed images recorded in the northern area of ​​Mars called Arabia Terra (an extremely eroded known as one of the oldest areas of the planet)

Researchers were able to identify signs of water evaporated long ago. ,, One of the lakes in the region can be compared with the amount as Lake Tahoe, '' Wilson said. The researcher explained that this lake was fed by a Martian valley south out of bed in the north and pouring a large pool called Heart Lake.


Heart Lake is part of the whole system of lakes and valleys that stretch 150 kilometers along the northern planet. The team estimated that the lake could support a quantity of 2,790 cubic kilometers of water. Based on information gathered from 22 craters in the area, the team concluded that these lakes there were two or three billion years. Meanwhile melted snow each season could supply all water areas.


Researchers said they found such formations in other parts of Mars, but the north and south of the equator humid regions were much more extensive.
