University of Southern California Specialistssuggested that Mars still has underground salt water reserves. And they may be the cause of strange dark divorces observed on the surface of the planet, which in fact may be dried water streams. This was reported in a press release published on the website of the university. A detailed analysis of the research published in the journal Nature Geoscience.
In 2018, American astrophysics withsupported by experts from the Italian Space Agency (ISA), a deep-water lake was found under the ice cap of the South Pole of Mars. According to the results of this discovery, researchers from the University of Southern California came to the conclusion that deep underground waters can be located at a depth of about 750 meters, while still being active and active, as a result of which surface currents may occur in some near-equatorial regions of Mars. waters
Specialists studied the characteristics of the foldedsurface of Mars, which is similar to the system of frozen flows of water. Such folds dotted the surface of some of the Martian craters. Earlier assumptions suggested that these geological features are associated with surface water flows or near-surface subsoil water.
“We assumed that this is most likely not the case. And put forward an alternative hypothesis that the folds on the surface of craters arose from groundwater sources of water under deep pressure. Most likely, they seeped onto the planetary surface, moving upwards through the cracks in the ground, ”said one of the researchers, Essam Heggie, in the article.
Heggy participates in the European project MARSIS(Mars Advanced Radar for Subsurface and Ionosphere Sounding - European Space Agency radar for sounding the ionosphere and deep layers of the Martian surface).
Researchers believe that groundwaterprobably exist outside the geographical zone of the Martian South Pole. According to them, there can be a whole extensive existing hydrological system on Mars that can squeeze groundwater onto the surface of Mars through cracks in craters.
“Experience has helped us come to such assumptions.derived from our research on desert hydrology. We observed similar mechanisms in the North African Sahara and the Arabian Peninsula. And it is this that helped us discover the same mechanism on Mars, ”notes Abo-Alib Zaki Abo-Alib, the lead author of the study, also from the University of Southern California.
Experts concluded that the cracks inSome of the craters of Mars have allowed water sources to rise to the surface as a result of underground pressure. Then the waters leaked, leaving behind themselves on the walls of craters pronounced linear reliefs.
