Liquid water on Mars extends the life possibilities on the red planet



Mexico, July 27 (Notimex) .- After European scientists discovered liquid water on Mars, the possibility of living on the "red" planet, of which only 10 percent of its area was mapped, was extended to its South Pole

Mexican scientist Rafael Navarro González, working with NASA and the European Space Agency (ESA) on Mars research, highlighted the find and estimated that it is likely there are more waters on this planet.

The specialist of the Institute of Nuclear Sciences (ICN, for its acronym in Spanish) of the National Autonomous University of Mexico (UNAM, for its acronym in Spanish) emphasized that the discovery of European researchers have important implications for science

Navarro González explained that due to the thickness and depth of the ice sheet, photosynthesis in the monitored area can not occur, which does not allow the arrival of light.

"The region would be completely dark and therefore microbial life would be chemosynthetic, ie energy from chemical reactions such as methanogenic bacteria," said the expert in a UNAM statement.

He explained that the existence of macroscopic organisms (as we know them) is impossible because they require more energy, which involves the use of oxygen and are anaerobic conditions in the area.

Another caveat, he said, is the ingress of nutrients the lake is completely closed; the exchange of nutrients could not be given, and that limits the amount of biosphere that could exist.

The NASA's Curiosity Collaborator also considers that another unknown thing holds, which keeps the lake in liquid form, as it is estimated that the presence of salts is essential in conditions below zero degrees, but it could be hydrothermal Give sources or another kind of energy.

Concerning the possibility of using the liquid used in future space missions, the university expert emphasized that there are international planetary protection protocols for the use of resources on other planets, although the possibility to use them for human use or to gain fuels , is not excluded.

"We know there are other places on Mars where there is water in the Arctic area where the Phoenix mission discovered ice," he added. But you could also have access to other sources of water, and that's exactly what the ExoMars mission is in, and it will try to capture liquid from the atmosphere for human use.

However, Doctor of Chemistry from the University of Maryland said that the great scientific discovery will be to have evidence for a biosphere on Mars, because this will change terrestrial biology and lead to a universal biology.
