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



Water on Mars could be active near the dusty planet, according to researchers at the University of Southern California (USC), USA. The unbelievable claim was made after a comprehensive study of potential groundwater sources outside the South Pole of Mars. In mid-2018, a research carried out in collaboration with the Italian Space Agency revealed that Marwasser is among the southern polar ice caps. Researchers are now excited about the opportunity to discover "active systems" of water deep underground and at the surface.

USC researcher American scientist Assam Heggy points out that geographic features near the equator of Mars suggest flowing streams of water.

So far, this so-called recurrent slope line has been associated with seasonal rivers of surface waters.

However, the new USC research suggests that the features are the result of another process.

Dr. Heggy said, "We propose an alternative hypothesis that they come from a deeply pressurized groundwater source that comes up along the bottom cracks at the surface of the earth. "

The USC researchers have suggested that water exists on Mars in a larger geographic area than previously thought.

If an active water system has proven itself, it would be 2.4 60 feet (750 m) of underground soil that could push water to the surface.

Study co-author Abotalib Z Abotalib, a postdoctoral fellow at USC, noted similar behavior of water systems in the drylands of the Earth.

He said, "We saw the same mechanisms in the North African Sahara and in the Arabian Peninsula, and it helped us explore the same mechanism on Mars."

According to Dr. Heggy and Dr. Abotalib has caused cracks in the numerous craters of Mars and the deep pressure in the subsurface, causing the water wells to reach the surface well.

The water then ran along the crater wall, leaving the distinct recurrence of Pistenlinea.

In their study summary, the researchers wrote: "The recurring runway on Mars is believed to be due to snowmelt, deliquescence, dry river, or shallow groundwater."

"Except for the Dry River Originally, these hypotheses imply the presence of superficial or near-surface volatiles Substances that allow the exploration and characterization of potential habitable environments within reach of existing technologies.

"Here we present observations from the High Resolution Imaging Science experiment, heat flow modeling, and terrestrial analogs that suggest that the source is recurring Hanglineae could be natural outflows along geological structures of saltwater aquifers in the cryosphere at a depth of about 750 m.

"Spatial correlation between recurrent source swelling regions of lineages and fractures with multiple scales ̵

"We suggest this deep groundwater occasionally appears on Mars under present-day conditions.

The study results are from researchers who analyzed data obtained from NASA's Lunar Reconnaissance Orbiter.
