Mars could remain active underground water sources
University of Southern California experts have suggested that Mars is still preserved underground reserves of saline water. And they may be the cause of the observed on the surface of strange dark streaks, which may actually be a dried-up watercourses. This was reported in a press release published on the website of the University. A detailed analysis of the study published in the journal Nature Geoscience.
The 2018 American astrophysicist with the support of experts from the Italian Space Agency (ISA) found under the ice cap of the South Pole of Mars deep lake. It was as a result of this discovery, researchers from the University of Southern California have come to believe that the deep groundwater, can be located at a depth of about 750 meters, it still remains active active, so that at any time, in some equatorial regions of Mars may have surface flows water.
Specialists have studied the characteristics of the folded surface of Mars, which is similar to the system of frozen water flows. Such folds is covered with the surface of some of Martian craters. Earlier assumptions were talking about the fact that these geological features associated with the surface water flow or subsurface water subsurface.
"We have suggested that the most likely is not. And put forward an alternative hypothesis that the folds on the surface of the crater emerged from underground water sources of water under high pressure. Most likely, they leaked on the planetary surface, moving up the soil cracks, "- said in the article, one of the researchers Essam Heggie.
Heggy involved in the European project MARSIS (Mars Advanced Radar for Subsurface and Ionosphere Sounding - Radar of the European Space Agency for the sensing of the ionosphere and the deep layers of the Martian surface).
Researchers believe that groundwater is likely to exist outside the geographic area of the Martian South Pole. According to them, on Mars there may be a whole vast hydrological functioning system capable of squeezing the groundwater to the surface of Mars through the cracks in the craters.
"To come to such assumptions helped us experience gained as a result of our research in the field of hydrology deserts. Such mechanisms we have seen in the North African Sahara and the Arabian Peninsula. And that is what has helped us to open the same mechanism on Mars "- said Abotalib Zaki Abotalib study's lead author and University of Southern California.
Experts have concluded that the cracks in some of the craters of Mars have allowed water sources to the surface as a result of underground pressure. Water then leaked, leaving the walls of craters pronounced linear reliefs.
