Salt Water Flowed on the Surface of Mars

The black lines similar cracks move from season to season on the edge of the crater surface of Mars. The flow of salt water is suspected as the cause of this movement. Since 2006, the U.S. space agency (NASA) lurking near the Red Planet from satellite orbiter using the Mars Reconnaissance Orbiter (MRO). Every day a camera mounted on the body of the satellite is capturing the dynamics of the planet's surface. Recent posts MRO portrait presents a view of the cliffs on the banks of the various craters of Mars. From the photograph, the scientists looked at the cracks in the cliffs moved since the spring, peaking in the summer. "This is clear evidence that water flowed on Mars," said principal investigator surveillance project of NASA, Alfred S. McEwen, who also teaches at the University of Arizona. Despite the summer, the temperature of Mars is still colder than Earth's average temperature. Therefore, McEwen estimates the water flowing through the cliffs of the crater has been mixed with salt is very salty, so the solution remains in the liquid phase locked despite the cold temperatures. There are seven craters that have similar views. Twenty other locations also indicate changes in the lines on the cliff. "Sites like this are very rare," he added. For years, scientists knew of the existence of ice on Mars. Geological formations such as canyons and dry river bodies showed that water once flowed on the surface of Mars some time ago when the Red Planet is hotter than now. The findings of this seasonal flow of salt water gives new hope to search kehiduoan simple on the surface of Mars. According to geology biochemist from Indiana University, Lisa M. Pratt, melting and freezing cycles on Mars-like events in the Siberian permafrost. In the frozen layer, living things adapt to survive. "Organisms on Mars is very likely to adapt to this cycle. They are looking for food when the water melts, then hibernate when the water freezes.*** [NYTIMES | ANTON WILLIAM | KORAN TEMPO 3614]
