Water on Mars: DISCOVERY active groundwater on the surface of Mars | science | news


Water on Mars can be active around the equatorial regions of the dusty planet, according to researchers from the University of Southern California (USC), USA. Incredible statement was made after careful consideration of the potential sources of groundwater outside the south pole of Mars. In mid-2018, a study conducted in collaboration with the Italian Space Agency shows the presence of water under the south polar cap of March. Researchers are now excited at the possibility of identifying "active systems" water deep underground and on the surface.

Ace Heggy, a researcher at USC, said geographical features near the equator of Mars suggest the presence of running water flows.

Until now, these so-called recurrent slope Linea were not associated with the seasonal flow of surface water.

However, a new study suggests USC feature a & # 39 is the result of another process.

Dr. Heggy said: "We propose an alternative hypothesis that they emanate from a deep source of pressurized groundwater, which comes to the surface moving up along the ground cracks."

USC researchers have suggested there is water on Mars as part of a wider geographic area than previously thought.

If confirmed, the active water system some 2,460 (75) may be causing the water to the surface of the ground.

Study co-author Abotalib Z Abotalib, a doctoral researcher at the USC, said such behavior of water systems in aridest regions on Earth.

He said: "We have seen the same mechanisms in North Africa and the Sahara, the Arabian Peninsula, and it helped us to explore the same mechanism on Mars."

According to Dr. Heggy and Dr. Abotalib, cracks in Mars numerous craters and deep beneath the earth helped pressure sources are well to the surface.

The water ran along the walls of craters, leaving behind a clear recurrent slope Linea.

The scientists wrote in their study abstract: "Periodic slope lineae on Mars was the hypothesis comes from snow melting, spreading, dry stream or shallow waters.

"For dry flow origin exceptions, these hypotheses have in mind the presence of surface or subsurface volatiles placing exploration and characterization potential populated environment within reach of current technology.

"Here we report the observation of high-resolution Imaging Science Experiment, heat flow modeling and terrestrial analogs which decrees that the source of recurring lineae inclination may be natural discharge along geological structures of saline aquifers within cryospheric at a depth of about 750 m

"Spatial correlation between repeating slope lineae source regions and multiscale fractures – such as joints and faults – in the southern mid latitudes and Mariner suggests that iterative slope lineae mainly comes from tectonic and impacts associated with fractures.

"We believe that the deep underground water is sometimes surface on Mars in the modern conditions."

The findings come after researchers analyzing data obtained by NASA's Lunar Reconnaissance Orbiter found evidence of "jumping" of water molecules on the moon.
