Mars is not 'hospitable' as people think

The results of a study by French and American scientists published in the September 9 issue of Nature Geoscience show that Mars is not a warm, humid planet and can survive life as Previous hypothesis. In contrast, "Red Planet" is considered a quite aggressive place with volcanic lava eruptions in volcanic form.

In previous studies, the scientists hypothesized that the essential minerals discovered on the surface of the "Red Planet" indicate the appearance of clay which is formed when water deforms rock. surface about 3.7 million years ago.

According to scientists, this sign shows that Mars is a warmer and more humid place, raising hope for the possibility of a planet of life.

However, the new findings of the research group provide evidence that completely denies the previous hypothesis. When studying clay taken from Mars, scientists found that the minerals in the soil including iron and magnesium, may have been deposited by water-rich lava, which is a mixture of calcined rock. completely flowing and fused stone partially under the surface of the Earth.

Alain Meunier of de Poitiers University (France) and his team compared clay minerals at Mururoa Atoll in French Polynesia with similar specimens taken on Mars.

The results show that the type of Martian mineral clay formed from the deposition of lava. This same process has occurred at other locations on Earth, including the Parana basin in Brazil.

Mr. Meunier said that to crystallize, clay needs water but not necessarily liquid water. In short, clay is not a specific land or rock is changed. Ghost clay cannot reflect anything about the weather conditions on Mars and cannot be based on clay to show that the planet has life without considering its early history.

If this hypothesis is true, this means that Mars may not be a place of life as previously thought that scientists have published. The group of scientists said they would conduct further research on this issue.
