04/14/2015 (The People’s Daily Online) – A team of researchers led by Spanish Javier Martin-Torres has just demonstrated that liquid water can Mars continue to exist at least during the night and in the equatorial area. The work, which has aroused great excitement among scientists studying the Red Planet.
Martin-Torres, the Andalusian Institute of Earth Sciences, a joint center of the CSIC and the University of Granada, has reached this conclusion after analyzing data from atmospheric moisture and temperature of the planet for a full Martian year (equivalent to more than two Earth years).
The analyzed data come from one of the rover’s instruments Curiosity, REMS (Rover Environmental Monitoring Station), a weather station in Spain designed by researchers at the CSIC and integrated in the vehicle NASA, which for years explores the Gale crater in the Martian Ecuador. At that time, the robotic vehicle has traveled more than 9 km. inside the crater.
According to research, within 5 inches of the crater floor environmental conditions exist for liquid salt water (brine) overnight. Shortly after dawn and as temperatures rise, pickles dry, but when night falls again salts in the soil (perchlorates), again absorb water vapor from the atmosphere. The results therefore suggest an active exchange of water between the Martian atmosphere and surface of Mars
“The presence of liquid water. – Explains Martin-Torres is an extremely significant event, as it is one the essential requirements for life to exist as we know it. During the hours in which liquid water is possible, however, Gale temperatures are too low for cell metabolism and reproduction such as currently existing on the Earth, but the possibility of liquid water Mars has huge implications for the habitability of the planet, for future exploration, and for all geological processes related to water. “
