The Martian lakes dry up to 30 miles wide and 3 miles from the crater located Gail (Gale crater) inside

American “Curiosity” rover project team on December 9 announced that “curiosity” was discovered on Mars a long dry ancient freshwater lakes have supported this theory, some simple microbes to survive.

Thermal anomalies exist “curiosity” was after 2012 craters on Mars landing Gail found near the landing point of a 5 m deep, is called “Yellowknife Bay” trench. Ground staff remote control “curious” was drilled on the ditch sedimentary analysis found that 3.6 billion years ago there was a wave rippling lake, which had existed for at least tens of thousands of years.

Researchers at the 9th annual meeting of the American Geophysical Union held in San Francisco pointed out that the PH value is neutral lake area, salinity is low, it should have been a freshwater lake. It also found that carbon, hydrogen, oxygen, sulfur, nitrogen and phosphorus and other key elements of life, which means that the lake can support the survival of prokaryotic microorganisms, such as rock composition can be decomposed to obtain energy and mineral inorganic autotrophic microorganisms. In some caves and hot springs on Earth vents, often find these microorganisms.

Britain participated in the study at Imperial College, Professor Sanjeev Gupta said in a statement: “This is a big step in Mars exploration billions of years ago, the lake calm underwater, there may be ancient. Many elements of the microorganisms into energy, think of this scene on the exciting “[Tencent Science Note: the text.” many elements of ancient microbial put into energy “is more accurate to say that the use of the chemical elements of ancient microbes can get energy. Here refers to a class can not rely on the sun, by “chemosynthetic” life forms to gain energy]

The researchers noted that there were signs before people discovered the presence of water on Mars, but the discovery of the remains of the ancient freshwater lake is the best evidence indicates that Mars was once habitable. The study, published in the latest issue of the U.S. journal “Science”.
