Gale Crater hosted life on Mars? NASA’s Curiosity reveals a lake could have hosted wide variety of microbial life
Based on the data revealed by the vehicle on Mars NASA scientists Curiosity said the skull on Mars Gale had good physical and chemical life conditions of 700 million years. They also claimed that during this period it was also a lake that could accommodate a wide variety of microbial life.
New discoveries have found room in the journal Science. The report shows a sustainable Martian environment that has the potential to house a wide variety of living things during that time.
“This helps expand our understanding of what would be a habitable environment on Mars, there are 31/2 billion years,” said author Joel Hurowitz, a geochemist at Stony Brook University.
NASA’s Curiosity rover to Mars reached Gale Crater in 2012 and since then it has been drilled, X-ray and laser overhead a variety of rocks to if Mars could have conditions to harbor life.
Mars Curiosity NASA’s Rover with its instruments was on a mission to drive to Mount Sharp, the 3000 mound in the middle of the crater. It would climb its tracks each layer of sedimentary student rock as a chapter of the geological history of Mars.
Curiosity also discovered evidence of water on Mars and the right chemical ingredients needed for life. According to recent studies, Gale Crater was once home to a number of lakes that may have come up and down over time.
Now, scientists have collected the testimony of several sites found on Mount Sharp and six samples include drilled from the rocks of very different ancient environments. As a result, we have found a large amount of life support ingredients such as compounds of carbon, nitrogen and phosphate minerals as well as iron and sulfur minerals in different redox states.
“Our analysis of these rocks indicates that gradients in the oxidation state of lake water were present in the primary lake environment,” the study authors wrote. “Overall, these results provide compelling evidence that the physical, chemical, and energy conditions necessary to establish a habitable environment were present on Mars between 3.8 and 3.1 (a billion years ago).”
In addition, a strange pattern was observed in a field in layers of rock. Some areas had a large amount of coarse sediment that pours quickly, making shallow water where water flows into the lake from a stream or river would have dropped much of its heavy material.
In addition, some areas had much sediment layered more progressively – closer to the center of the lake and near the mouth of the river.
It appears that minerals present in the shallower parts of the lake are more exposed to oxygen than minerals in deeper areas.
It appears that Lake Gale Crater stood out in an oxygen-rich layer of the surface layer and an oxygen-poor layer in its depths. This is very similar to similar lakes on Earth, which differ in the same way.

“It’s this relationship between mineralogy and the thickness of sediment layers that allows us to connect the dots,” said Ashwin Vasavada, co-author of the study, the project scientist for the mission at the Jet Propulsion Laboratory.
Hurowitz said the lagoon complex could have lasted hundreds of thousands of years to 10 million years. Like lakes on Earth, the Gale Crater could accommodate a variety of microorganisms.
