Hydrothermal cracks around Martian impact craters could be suitable places for living organisms, according to scientists.
The new study, manner jointly by the University of Leicester and the Open University, led by lead author John Bridges of the University of Leicester has determined that the temperature on Mars were in the range of about 50 to 150 degrees Celsius. On Earth, microbes can survive in such an environment, such as the volcanic thermal hot springs of Yellowstone National Park, USA, suggest the researchers.
The scientists analyzed samples of one of the types of meteorites, called naklitami. In veinlets naklita researchers found iron carbonate, formed usually in water saturated with CO2, at about 150 degrees Celsius, and later in the veins located layers of clay formed by the cooling of the water to 50 degrees Celsius.
The work was presented in the journal Earth and Planetary Science Letters.
