For centuries the existence of water on Mars is the theory. Early telescopes showed ice hats and early astronomers point out channels that create natural channels or create channels.
Over the past two decades, rogarner, soul, chances and curiosity have been sent to scientists who attempt to interpret the surface of the planet and cover the past or present evidence.
After "Red Planet" landing in August 2012, "Callius Rover" spent 20 kilometers in Gale Graert. Robert studied 400 meter sedimentary rocks in the Kratt, says Jezan Heydar Jackson, Mississippi, including rocks from 3.7 to 4.1 billion years (noon time).
Heydar and colleagues used these pictures of sedimentary rocks to learn geological processes that occurred millions of years ago on Mars. He presented their conclusions on Sunday in the US Geological Society's Annual Meeting in Indiana, Indiana.
The researchers found four distinct units in the 400-meter range that are different deposits and heydari says "in my opinion, all these packets are deposited in water."
One of the packages, called a hammockking base unit, is a conglomerate cereal with 20 centimeters. Curiosity imagery showed the hummocky plain section of the rhythms, round cobbons and cross beds attached to a 4 meter height that was deposited in water.
In addition, some pictures have a height information that can create a surface topographic profile to publish queues profiles. "These ridges are asymmetrical," heydar said. "In other words, they were formed in one direction.
After looking at pictures, Heydar says he immediately thought of Washington. Mars's rhythms are equally halted, he says and adds that they are roughly twice in Scablands. The earth and the earth's clusters had similar properties, but it was not until Heidar concluded that the deposit of Mars had resulted in large-scale floods.
Heydar compared to the Earth's rivers, notes that a 4 meter height cross will flow to the depths of 10 to 20 meters. "This is one reason to say that these deposits are related to floods and not on the banks of the river," he says.
Heydar says that the niche sedimentary rocks found in Gail Krater could have been brought to Pliostocene on Earth (about 2 million years ago 12,000 years ago), with large-scale global ice and dramatic floods.
"On both planets, one of the Earth's Hemorrhoids broke out in the north of the earth, the southern hemisphere of the earth and the other hemisphere was warm," heydar said. He adds that this comparison is important because it shows that the oldest Mars is similar to Plistocene's Earth, where liquid water is stable and is a life-saving.
