On Mars, found the footprints of a giant flood March 10, 2013


While some breathlessly watching developments around the historic mission “Kyuriositi” and the current problems he faced , others wonder the new data obtained from the Martian satellite orbit Mars Reconnaissance Orbiter (MRO), which circles the planet since 2006. His latest 3D-surface scan revealed a gigantic system of channels, which scientists believe formed due to the very large floods that raged on the planet 500 million years ago.

It is believed that during this time the red planet could be described in the following words: cold and wet. New data will help scientists determine the extent of involvement (or non-involvement) of the floods in changing the overall climate of the planet.

Very long canal system Marte Vallis sprawled on the Martian surface at 1000 km, and is located near the equator, in a place which was called Elysium Planitia. This plateau is the oldest known volcanic region on Mars, which over millions of years was buried under volcanic ash with the system of canals.

Scanning prompted scientists thought that Marte Vallis channels formed in two stages. First, water is lost from the smaller channels, and then the key wider and deeper. Water fills them first is the huge giant cavities, and then was spewed from the bowels or due to excessive volcanic or tectonic activity.


To determine the location of the research team used a special camera Shallow Radar (SHARAD), located on the MRO, and then had built 3D-model based on the data obtained. They found that the resulting system is very similar to the more ancient and previously discovered channels, including the pool Chryse, which scientists believe was once formed due to the large amount of water.

Compared to the size of the flood Chenneld Skeblend – giganstkogo skeblenda formed by catastrophic floods on the Columbia Plateau basalt in North America.

Gareth Morgan (Gareth Morgan), a geologist at the Center of the National Air and Space Museum in Washington, DC said:

“Our findings show that the early assumptions about the level of erosion in the world, which are formed by these channels were not quite correct. Channel depth was at least two times greater than in earlier calculations. ”
