Ancient lake on Mars harboured diverse microbial life: study
Sustainable lake in ancient Mars may have provided adequate environmental conditions for different types of microbes exist simultaneously more than three billion years ago, scientists have found data from the Roios mission NASA’s curiosity.
This means that the water had high physical differences in different parts of the lake or chemical. Shallow water was richer in antioxidants than deeper water, according to researchers.
“These are very different environments and coexist in the same lake,” said Joel Hurowitz of Stony Brook University in the US.
“This type of oxidizing stratification is a common feature of Earth’s lakes, and we’ve now found it on Mars,” Hurowitz said.
“The diversity of environments in this lake of Mars would have to survive several types of microbes, including those that grow under conditions rich in antioxidants, those that thrive under low oxidative conditions and those that inhabit the interface between these parameters,” he said. .
Mars life ever lodged is still unknown, but the search for signs of life on any planet Mars – or more – distant frozen worlds – begins with the reconstruction of the environment to determine if it was able to bear life.
The main objective of curiosity when landed inside Gale Crater in 2012 was to determine whether Mars has ever offered favorable environmental conditions for microbial life.
In its first year, on the ground of crater “Yellowknife Bay”, the vehicle was found evidence of ancient environments of freshwater rivers and lakes with all the chemical ingredients of life and a source of energy to be for life.
As curiosity has led to the base of Mount Sharp, a layered mountain within the crater, and inspected layers of rocks become progressively younger when the vehicle is gaining in height in the lower Sharp Mount.
“These results give us unprecedented detail to answer questions about the ancient environmental conditions on Mars,” said Ashwin Vasavada, the scientific curiosity behind the project, NASA’s Propulsion Laboratory in the United States.
