The US space agency’s probe "NASA" on a mountain "mustache" It is about 5 km high and has clay minerals formed from the lakes and streams that were flowing through the summit. "Gale Crater" central للمريخbut those streams dried up turning into sand dunes and sediments.
and according "NASA" The area has shifted from being rich in mud to one full of salty mineral sulfates, which could indicate a significant shift in Mars climate It happened billions of years ago.
According to the site, "Gizmodo" specialist with scientific news And technology, the rise of the probe "Curiosity" For higher altitudes on Mt "mustache"accompanied by the discovery of more sulfates.
The probe will soon begin digging the last rock sample collected in the transitional zone in the hope of learning more about the change in the mineral composition of the rocks in that region.
Explained Ashwin Vasavada, Project Leader "Curiosity" At NASA’s Jet Propulsion Laboratory, in a press release: "We no longer see the lake sediments we saw years ago low on Mount Sharp. Instead, we see plenty of evidence of drier climates, such as dry sand dunes that were sometimes swirled by streams. This is a big change that happened to lakes that lasted millions of years before".
The statement added: "The area that Curiosity is currently exploring also includes hills that may have formed in dry conditions, and feature large windswept sand dunes that are likely to harden into rock over time.".
The probe was also found "Curiosity" according to "NASA" There is evidence of sediments that were carried by water currents across the dunes, and these sediments now appear as stacked layers of scaly-looking rock.
Despite the dry environment of Mars today, scientists believe that it may have been habitable one day, as it included bodies of water, and after losing "red planet" Its atmosphere dried up its water.

The US space agency’s probe monitoredNASAOn Mount Sharp, which is about 5 km high, there are clay minerals formed from the lakes and streams that flowed through Gale Crater’s central summit. للمريخbut those streams dried up turning into sand dunes and sediments.
According to NASA, the region has shifted from being rich in mud to one full of salty mineral sulfates, which could indicate a significant shift in Mars climate It happened billions of years ago.
According to the specialized “Gizmodo” website, with scientific news And technology, the rise of the probe “Curiosity” to higher heights on Mount “Sharp”, was accompanied by the discovery of more sulfates.
The probe will soon begin digging the last rock sample collected in the transitional zone in the hope of learning more about the change in the mineral composition of the rocks in that region.
“We no longer see the lake sediments that we saw low years ago on Mount Sharp,” Ashwin Vasavada, Curiosity project leader at NASA’s Jet Propulsion Laboratory, explained in a news release. Instead, we’re seeing a lot of evidence of drier climates, such as dunes. “Dry sandy ones that sometimes had currents circulating around them. This is a big change that happened to lakes that lasted millions of years before.”
“The area that Curiosity is currently exploring also includes hills that may have formed in dry conditions, and feature large, windswept sand dunes that are likely to solidify into rock over time,” the statement added.
The probe “Curiosity”, according to NASA, also found evidence of sediments that were carried by water currents through the sand dunes, and these sediments now appear as stacked layers of rocks with a scaly appearance.
