Martian lakes may contain fossils fossils Facts

Judging by the lakes and oceans in the northern hemisphere of Mars in the distant past the planet had water. In a recent study by NASA and the European Space Agency by Brown University found that about one-third of the former lakes contain deposits of clay, very similar to fossils of living organisms on Earth. Further study of these lakes is important for science, as in future Mars missions can be organized astrobiologists to search for signs of life on the red planet.

The hypothesis is that if Mars was habitable planet, the whole life centered around water, traces of which may remain in the river and lake sediments, fossilized over time. In order to study these deposits from the Earth can be sent ATVs for drilling and sampling which will then analyze for the presence of biological material.

To determine which of the Martian lakes location clay samples most likely to scientists via satellite was studied by the reflection of light from the bottom of these lakes. It turned out that such places only 79 of the 226 surveyed. These figures may reflect the fact that the geological processes on Mars are quite different nature, or that the water remained on the planet a short period of time. Details of the study published in the journal Icarus.

To find out how the water has interacted with the Martian soil on the planet rover scheduled to launch MSL, which will arrive in August 2012 to investigate the Gale Crater.
