Mars still has deep underground active waters: Scientists


New York: Deep groundwater could still be active on Mars and be the source of surface currents in some quasi-equatorial areas of the "Red Planet," the researchers suggest.

Researchers at the University of Southern California (USC) have determined that groundwater probably exists in a wider geographic area than just the poles of Mars and maintained that there is an active system up to 750 meters from where groundwater reaches the surface . craters in the specific craters they analyzed.

The team studied the characteristics of the Recurrent Line of Mars, which are similar to the dry and short currents of water that appear on some walls of the crater on Mars.

Scientists had previously thought that these features were affiliated with surface water flow or groundwater flow, said research scientist Essam Heggy of USC.

The team found similarities between groundwater movement mechanisms in the Sahara and on Mars.

"Groundwater is strong evidence of the similarity of the past between Mars and Earth – suggests that they have a similar evolution to some extent," Heggy said.

He noted that this deep source of groundwater is the most convincing evidence of similarities between the two planets – suggests that both may have had wet periods long enough to create such an active groundwater system.

"Understanding the evolution of Mars is crucial to understanding the long-term evolution of our own Earth and groundwater is a key element in this process," Heggy said.

Heggy explained that fractures within some craters of Mars allowed water springs to rise to the surface as a result of the deep pressure below. These springs leaked to the surface, generating the distinct and distinct linear characteristics found on the walls of these craters.

They also provide an explanation of how these characteristics of water fluctuate with seasonality on Mars.

The study suggests that groundwater may be deeper than previously thought in areas where such currents are observed on Mars.

For the study, published in the journal Nature Geoscience, the team used high resolution optical images and modeling to study the walls of large impact craters on Mars.
