Hypothesize that Mars could be the place where human beings live, getting closer to the truth.European Space Agency or the European Space Agency (ESA) states the condition of the red planet suitable for life support - especially the fact that Mars has water content.
Hydrated silicate minerals found by the two satellites, ESA's Mars Express and Mars Reconnaissance owned by U.S. space agency, NASA's orbiting a star in the northern lowlands of Mars.
Found indications that water once flowed there. According to principal investigator for Mars from the University of Paris, Jean-Pierre Bibring, water flowed to the surface of Mars about four billion years ago and only lasted a few hundred years."Research shows water ever existed on Mars, but not in a big sea," said Bibring.
Evidence indicates, the Martian crust hydrated in the same way, both north and south.These latest findings contradict the results of American research team published last June 13 in the journal Nature Geoscience that said, the ocean covers a third of the surface of Mars, about 3.5 billion years ago.
"At that time, Mars has lost its atmosphere. Accordingly, the water is no longer stable in the liquid state at the surface," Bibring said."The flow of water can still flow, however, lack of water on the surface means there is no potential for the formation of sea level."
Added Bibring, pressure and temperature when water was not given an opportunity in a stable condition - the liquid state - on the surface. "Some water evaporates, while others went into the ground."
Water, Bibring said could remain on the surface for several days, or weeks. But does not millions of years later.
The researchers found water flowing on Mars a few hundred million years ago - when the sun melt the ice there.
Evidence about a dozen channels that are in the melt glaciers on Mars - scientists have admitted surprise, because the presence of water on Mars could say 'just' than previously thought.
"We think that the planet Mars is cold and dry completely. This fact will change the way we look at Mars," said Brown University planetary geologist, Caleb Fassett.
