Mars rover discovers evidence of ancient waterways in Gale Crater region

Rover gets NASA’s curiosity a direct look at an area previously unprecedented from the orbit that features a “square” pattern, along with evidence of old waterways, including rivers, lakes and perhaps the ocean.

New photos and data from Mars Rover have already raised questions about how to change the surface of the red planet billions of years ago. Scientists are still unable to answer the reason why the planet’s water is dried and turned the surface into a cold desert.

There is a curiosity in an area called Gale Crate, and the evidence has shown that when it was formed, the water was leaking under the surface.

NASA said Rover had found evidence of the presence of groundwater in the hole when it faced low underdeveloped hills, some of which were only a few inches and geologists described as a square style.

Under the hills, the formed basic scientists believe when the groundwater flows through the rock and left behind the minerals that have accumulated in the cracks and the east. Then the stiffness of the minerals and cement is similar.

The configurations were worn after NASA described “sand pin” from the wind of Mars, although the minerals remained and revealed a network of resistance hills at home.

Rover has already analyzed the hills that scientists say it looks more likely.

But the patterns created over time extend across the miles of a layer on a sharp mountain of 3 miles. NASA said Rover has climbed the foothills of Mount Sharp since 2014.

What scientists also find interesting about the squares of the squares is that they have not been found anywhere else on the mountain by public orbits or curiosity.

“There is a great mystery that is why the hills have been hardened in these large patterns and why only here.” “As we continue, we will study hills and mineral faults to ensure that our idea of ​​how to be on the goal is.”

NASA said that the patterns are located in a part of the Sharp Mountain formed during different eras of the ancient Mars climate. Therefore, while Rover ascends from the oldest to the smallest, the time to travel and search for signs of water on Mars and which were the environments that supported microbial life in ancient times.

“Rover is currently exploring a layer with an abundance of salty minerals called magnesium sulfate, which form with drying of water,” NASA said. “Their presence here indicates the appearance of this layer when the climate is more dry.” Miscellaneous, the squares of the squares show that even in the midst of this drying, the water was still under the ground, creating changes seen today. “

Modern exposed clues on Mars may provide an additional vision for scientists about the reason for the formation of squares of squares where they did.

NASA said that the basis between the hills contains many small fractures filled with white veins of calcium sulfate, which is a salty mineral that leaves it when the groundwater flows through cracks in the rocks. In the lower layers of the mountain, the similar veins were abundant, and even enriched with mud. However, so far, none of the veins have been monitored in sulfate.

“This is really surprising,” said Abyel Freeman of JPL. “These calcium sulfate veins were everywhere, but they disappeared in one way or another with our rise to the top of the Sharp mountain. The team is excited to find out the reason for their return now.”

The Curiosity Rover was launched on November 26, 2011, landed in Mars on August 5, 2012. Its mission was to know whether Mars had the appropriate environmental conditions for life support, and early, Rover discovered chemical and metal evidence of housing environments from the past.
