Far from a science fiction story, the space race to find traces of life on Mars or elements confirm that existed in the past liquid water on its surface has begun to change the image that had the red planet.
Today we know that is capable of accommodating ocean, rivers, lakes, forests, climates and ecosystems that would make this desert planet livable, but not only that arrived to colonize the first "Martians" from land could be 50 percent higher than humans, lighter and musculoskeletal system very different.
The exploration of that planet, currently has two space missions, the Mars-Express, the European Space Agency, and led by the National Aeronautics and Space Administration (NASA, for its acronym in English), which managed to send to successfully the twin robots Spirit and Opportunity, whose mission is to locate any trace of liquid water existed on the Martian surface, and thus the possibility of finding life.
Demonstrate that the red planet once had water on its surface "would be a great discovery, because it could support the hypothesis we have that life existed at some point" and "different kinds of organisms," said Rafael Navarro Gonzalez, a researcher Institute of Nuclear Sciences of the Universidad Nacional Autonoma de Mexico and a consultant for the NASA space missions to Mars.
Present vital Navarro, an expert in analytical chemistry, atmospheric and planetary, said the recent discoveries of the Mars-Express, which confirm the presence of frozen water in Mars' southern polar cap, "also are important because they indicate that present one of the essentials for life to have had in the past, plus it surely could have water in the subsoil, although so far no direct evidence.
