Liquid water exists on Mars - VIDEO PDF Print E-mail

NASA scientists said that the water on Mars can exist in liquid form. Keep it in this condition for some time can salt detected earlier rover Curiosity. Scientists recognize that the brine on Mars is unlikely to support life, but do not despair to find her.

Scientists working in the framework of NASA, concluded that water on Mars can exist not only in the gaseous state and in the form of ice, it was believed until now, but in the liquid form. This is stated in the study, the results of which were published in Nature Geoscience.

After the landing of the fourth rover NASA in late 2012 in the crater Gale were found perchlorates - salts ethereal acid. Further observations Curiosity shown that these substances are found on the surface of Mars is almost everywhere. Now scientists say that these salt water can help to achieve a liquid state on Mars.



"We found in soil samples calcium perchlorate, which under certain conditions absorbs water vapor from the atmosphere. Data from the meteorological station on Mars rover Curiosity indicate that such conditions on Mars formed during the night and in the early hours after Sunrise in winter. Based on research conducted at the height of about five feet, as well as directly on the surface of the planet, measuring humidity and temperature indicators, we can roughly calculate how much water there is formed, "- said Morten Madsen of the University of Copenhagen.

"When night falls, some of the water vapor from the atmosphere condenses on the surface of the planet as frost, but calcium perchlorate strong and absorbent properties of the water it creates brine freezing point drops and frost can turn into liquid" - he explained.

Life in such a liquid NASA researchers find no hope because of the low temperatures, the damaging radiation from the Sun, in the absence of the atmosphere and perchlorates toxicity to living organisms. But the very existence of liquid on Mars gives hope to find life, if not at the equator, where the studies were conducted in other latitudes of the Red Planet. Scientists have expressed the hope that they will be able to detect the similarity of water in temperate and polar latitudes, where the planned landing the next Mars rover.

Not long ago, a group of scientists from NASA published the results of his research, according to which it was found that billions of years ago there was a body of water on Mars, which could accommodate a more water than the Arctic Ocean on Earth.

Earlier rover discovered and photographed on Mars traces of an ancient lake. Curiosity, drilled a hole in the rock, found organic molecules, which, according to the researchers, may have formed at the bottom of the water: it could be a lake or even a system of lakes that are located in the crater Gale, which originally landed rover. The composition of the soil near the mountains Sharp crater heterogeneous, with some of its layers were formed under the influence of water, and some - by the wind.
