Hide water on the Red Planet - Spiegel Online

The question of whether there is water on Mars, planetary scientists have long vexed. Meanwhile, the answer is clear. In the past, huge floods rushed over the planet. And even today there is water on the surface of the Red Planet. The in June 2012 landed in Gale Crater rover “Curiosity” was detected in soil samples traces of the vital connection. In several professional articles in the journal “Science” researchers report on the work of Rovers in recent months.

“One of the most exciting results of the very first solid sample, which has ‘Curiosity’ is incorporated, is the high proportion of water,” says Laurie Leshin from Rensselear Polytechnic Institute in Troy, New York. The rover had a heated shovel full of Martian soil in an analysis chamber (“Sample Analysis at Mars,” SAM) to 835 degrees Celsius. Other than water and carbon dioxide, sulfur dioxide and oxygen – Here, volatile compounds from the sample broke. Leshin and colleagues estimate that the proportion of water to around two percent.

is not only scientifically interesting but also a remarkable resource. “We now know that there should be plentiful and easily accessible water on Mars,” said Leshin. “If we send people there, they could pick up the ground somewhere on the surface, heat and water had.”

From the data obtained, the researchers conclude also that the loose Martian soil is blown all over the Red Planet. Mars possesses a kind of global layer was mixed and distributed by the frequent dust storms, Leshin says.

water sources also suggest other of “Curiosity” derived data: The first stone of the rover had investigated on the Red Planet, differs from all other previously known Martian rocks, as another research team in “Science” reported. Called the pyramid-shaped, volcanic boulders, “Jake_M”, was assigned to the so-called Mugearit.

“We know how Mugearit on earth is formed,” said Martin Fisk of Oregon State University. “The process begins with magma deep in the earth, which crystallizes in the presence of one to two percent water, the crystals separate from the magma The part that does not crystallize coming sometime later during a volcanic eruption at the surface..” – And that is Mugearit. The discovery of similarly built-rock on Mars that is indicated on water resources deep below the planet’s surface. Although the evidence is not waterproof, as the researchers point out.
