The specialists of the University of southern California have suggested that Mars is still preserved underground reserves of salt water. And they can be the cause of observed on the planet’s surface strange dark streaks that actually can be a dried-up water flows. About it reported in a press release published on the University website. A detailed analysis of the study published in the journal Nature Geoscience.
In 2018 American astrophysicists with the support of experts from the Italian space Agency (ISA) found under the ice cap of the South pole of Mars deep-water lake. Is based on the results of this discovery, researchers from the University of southern California have come to believe that the deep underground water can be located at a depth of about 750 meters, at this still active, resulting in any time in some Equatorial regions of Mars may occur in surface streams of water.
Experts have studied the characteristics of a folded surface of Mars, which is similar to the system of frozen rivers of water. Such folds are dotted with the surface of some of the Martian craters. Earlier speculation said that these geological features are associated with surface water flows or surface water depths.
“We have suggested that, most likely, it is not. And put forward the alternative hypothesis that the folds on the surface of the craters originated from underground water sources in the water under deep pressure. Most likely, they were leaked on the planetary surface, moving upwards in cracks of the soil,” — said in the article, one of the researchers the ESS Heggie.
Haggie involved in the European project MARSIS (Mars Advanced Radar for Subsurface and Ionosphere Sounding Radar for European space Agency for sensing of the ionosphere and the deep layers of the Martian surface).
Researchers believe that groundwater is likely to exist outside the geographical area of the Martian South pole. According to them, Mars may be a extensive functioning hydrological system is able to squeeze out underground water to the surface of Mars through the cracks in the craters.
“Come to that later helped us experience gained as a result of our research in the field of hydrology of deserts. Such mechanisms we observed in the North African Sahara and the Arabian Peninsula. And that has helped us to open the same mechanism on Mars,” said Abotalib by Zaki Abotalib the study’s lead author also from the University of southern California.
Experts came to the conclusion that cracks in some of the craters of Mars allowed water sources to rise to the surface as the result of underground pressure. Then water leaked out, leaving behind on the walls of craters pronounced linear reliefs.
