|NASA Discover The Powerful Evidence of Water on MarS|
Some of the findings of NASA's new spacecraft showed Mars could support human life in the future.
NASA orbiter images transmitted 'Reconnaissance' show evidence of water on Mars in the summer.
U.S. spacecraft orbiting the Red Planet, Mars Reconnaissance Orbiter, shows there is a possibility that one day the planet can support human life. Orbiter has found the strongest evidence that on Mars there is water flowing in the summer.
Charles Bolden, head of the National American Space Agency or NASA, said NASA's Mars Exploration Program continues to make scientists more closely to determine whether Mars can support most life.
According to him, the program has shown that Mars is an important goal for future human exploration.
Mars Reconnaissance Orbiter reviewing many of the slopes along the southern hemisphere of Mars. Dark line on the side of the mountain looked like fingers. These signs appear and disappear as the change of seasons.
Signs appear when the temperature of the planet Mars rises. They look bigger as it moves into the mountainside. When the temperature is cold, dark lines disappeared. However, reappeared on the planet Mars in the next spring, or summer.
Alfred McEwen, principal investigator in Experiment Shooting in high resolution Mars Orbiter Planet who is also Professor of Geology at the University of Arizona in Tucson, said the flow of salty water that is the best explanation of observations of Mars orbiter. Other spacecraft and various Martian meteorites have shown that the surface of Mars salty.
According to McEwen, water on Mars may differ from those found on Earth. He called water on Mars is more like a viscous liquid. Magazine "Science" published a report on the findings of the orbiter.
McEwen and his team believe that the water probably flowed on ancient Mars. However, if water in the Red planet exists as a liquid is still debatable. The results of oxidation of iron in the planet makes the planet Mars is reddish.
Philip Christensen, a geologist at Arizona State University, confirmed scientists have known for years that there is ice on Mars.
"We know Mars had a lot of ice. However, this is not the first time we have seen the potential for liquid water. That may be salt water. But it was liquid. And I think that's the real key here. Not that Mars does not have much ice, but liquid water - a definite for an organism-are very different from the ice, "said Philip Christensen.
Geologist Lisa Pratt of Indiana University welcomed the results of the study. According to him, the findings will help scientists plan a trip in the future to look for signs of life on Mars today.
