Salt water periodically appears on Mars
Source:
The possibility of the existence of water in liquid form on the surface of Mars was first proved in 2000, when the spacecraft Mars Global Surveyor has discovered on the red planet channels formed by the threads of the then unidentified liquid. In the continued presence on the planet large quantities of water and ice was predicted by the Mars Rover “the Phoenix”, who worked in the circumpolar regions of Mars. It is known that then scientists are faced with a hard white substance that evaporated just a few days after detection. Almost elusive Martian water was discovered on the bottoms of some craters, and under the surface of the planet a rusty color. New studies of the surface of Mars, published on the portal , show that streams very salty water can form on the red planet for a few days a year. What can give their discovery to modern science?
is There water on Mars?
Due to the rather harsh climatic conditions , water, even in solid form quickly sublimates into the atmosphere of the red planet, dissipating before reaching the point of melting. However, studies show senior researcher of the Institute of planetology Norbert Schorghofer, the fourth farthest planet in the Solar system there are several areas of great interest to the scientific world. So, in some areas, usually lying in the middle latitudes, you can find shaded areas, where during the long Martian winter accumulates a large amount of ice. When the spring again the sun rises, the ice suddenly heats up. In the detailed model predictions increases with temperature -128° Celsius in the morning to -10° Celsius at noon — a dramatic change in the course of a quarter of the day. In such a short time not all the ice has time to get lost in the atmosphere.
due to the fact that Mars has an extremely thin atmosphere, the elevation of the ice melting on the planet is much lower than on Earth
Due to the fact that salt significantly lowers the temperature of melting and H2O of the Martian liquid can be formed at a temperature — 10°C. in addition, the shaded areas appear and the so-called carbon dioxide ice, commonly used on Earth in refrigeration plants.
Despite the fact that today Mars the fluid is extremely rich in salts substance in ancient times, the local water had a quite comfortable level of acidity and could even become a source of the origin of life. Anyway, even if you have never had your own at least basic inhabitants, discovered the source of liquid can help the future colonists of Land for the creation of future outposts and settlements. So, even seasonal streams may indicate the presence of vast reservoirs of moisture lurking beneath the surface of the planet, which, in turn, can be used in the irrigation of specially equipped greenhouses on the equator in the near future.
