n the past decade, it was revealed astronomers for the presence of mud in several places on the surface of Mars, in a reference to the presence of water once covered large areas of the planet, but a recent study revealed the existence of lava contributed to the occurrence of moisture in some places on the surface of Mars, and this means that Mars was not submerged water Contrary to the expectations of the scientists.
There are in the region of France called "French Polynesia" French Polynesia is moist soil formed by cold lava in the distant past and not because of the water itself, a situation quite similar - according to a recent study - what happened on Mars millions of years ago.
French researcher "Yen monier" Alain Meunier of the University "De Puechrz" Université de Poitiers French said that if formed on the Martian soil clay is not a condition that contain water or that it was formed by water, but are formed also by lava cold, these results hold idea the existence of life on Mars in the distant past on the grounds that the existence of life associated with the presence of water.
Along the river beds on the ground, near the ocean, we note that the clay soils are concentrated near water sources, and work running water on the transfer of chemicals from the rocks to the other areas that turn to substance clay moist, and this process takes a long period of time. But on Mars, the situation is completely different, where to have a clay soil and the presence of rivers, oceans and streams, a phenomena not see the water now, at least on the surface of Mars.
But the study conducted by the "monier" with the participation of a number of geologists French four years ago, showed that the clay soil on the island, "Mururoa" reefs Moruroa Atoll in the "French Polynesia" in Pacific Ocean formed by lava cold and not water the ocean, as the lava Dissolved formed small spaces inside the lava-like "pressure pots small" Tiny Pressure-Cookers and which are doing the last generation of minerals, such as iron. Preview has been located in the mud of this volcanic island and found very similar to the existing mud on Mars.
The sample Martian only on the ground and has previewed mud on the island "Mururoa" reefs came to earth in the form of a meteor ripped off for Mars in the past and fell to the ground and was called "meteor Lafayette" Lafayette Meteorite found in the warehouse University "Bordeaux" French Purdue University, which has been detection of Martian origin in 1931 AD, where the team revealed a geological similarity to a large extent between the meteorite and the mud sample on the island.
The Professor "Brian Hynek" Brian Hynek of the University of "Colorado" University of Colorado has sent a letter to the Web site "MySpace. Com" SPACE.com which pointed out that the meteorite in question does not represent the general situation of the nature of volcanic lava on the surface of Mars, as he said in a his letter that he did not believe that this new study will change the global view of the red planet, and it alters our view on the mechanism of a clay minerals only.
He added, "Hynek" says that water is the key element for the existence of life, so scientists are always looking for the presence of water areas to search for the existence of life in these areas, but the chances of search for life in the volcanic rocks are less mud, no doubt.
But asserts, "Hynek" It is not necessary to be all Martian clay soils have been formed in the same way, and even on the ground is also not formed soil ground in the same way, however, we find that exist in the areas of life and different environments on earth.
In any case, the space probe "Kiraossite" Curiosity, which fell on the surface of Mars in August 2012 last year, near the nozzle "Galle" Gale Crater task of drilling in this area wet clay to judge the validity of this study, whether or not in the near future.
