Data from NASA's Curiosity rover hints at ancient Mars mega-flood: study

In this news, we discuss the Data from NASA's Curiosity rover hints at ancient megaflood in Mars: Study.

Giant flash floods already passed through Gale crater on the equator of Mars about four billion years ago, according to a study that hints at the possibility that life may have existed on the Red Planet.

The research, published recently in the journal Scientific Reports, evaluated data collected by NASA’s Curiosity rover – launched in November 2011 – and found “gigantic flash floods,” likely triggered by the heat of a meteorite impact , freed the ice stored on the Martian Surface.

Based on the analysis, scientists, including those at Cornell University in the United States, said the floods of “unimaginable magnitude” created gigantic ripples which are telltale geological structures familiar to scientists. on earth.

“We identified mega-floods for the first time using detailed sedimentological data observed by the Curiosity rover,” said study co-author Alberto G. Fairen of Cornell University.

According to scientists, geological features, including the work of water and wind, have been frozen in time on Mars for about four billion years.

They said these characteristics convey processes that have shaped the surface of Earth and Mars in the past.

This case includes the appearance of giant wave-shaped features in the sedimentary layers of Gale Crater, often referred to as “mega-varieties” or “antidunes,” which are about 30 feet high and are spaced about 450 feet apart, the lead author Ezat Heydari, professor of physics at Jackson State University in the United States, noted.

Antidunes point to mega-floods that sank to the bottom of Mars’ Gale crater about four billion years ago, which is identical to the features formed by the melting ice on Earth about two million years ago, Heydari added.

According to the study, the most likely cause of the Mars flood was melting ice caused by heat generated by a large impact, which released carbon dioxide and methane from the planet’s frozen reservoirs.

The water vapor and the release of gas combined to produce a short period of hot, humid conditions on Mars, the researchers said.

They believe that the condensation may have formed clouds of water vapor, which in turn likely created torrential, possibly planetary, downpours.

This water may have entered Gale Crater and combined with water flowing down from Mount Sharp into Gale Crater to produce gigantic flash floods, the scientists added.

The science team on the Curiosity rover had previously established that Gale Crater once had persistent lakes and streams in the ancient past.

Researchers believe these long-lived bodies of water are good indicators that the crater, as well as Mount Sharp within, was able to support microbial life.
