Scientists have stated that Mars has billions of rivers "larger than those we know on Earth".
The "independent" journal of experts confirmed that "water courses of ancient times have dug deep canals on the surface of Mars in hundreds of sites"
The NASA "Corriete Rover" vehicle sent images showing the effects of these large sewers. "Most of these rivers are twice as wide as the planet," experts said.
Evidence suggests that these rivers have existed for about a billion years, but the few data available keep the subject somewhat ambiguous.
"It is difficult for us to explain the formation or existence of rivers or lakes on the basis of the few information we have," said Dr. Edwin Kitt of the University of Chicago, cited by the Independent.
According to scientists, the amount of water flowing in the rivers of Mars ranges from 3 to 20 kilograms per square meter per day.
According to Science Advances, this estimate, after studying more than 200 of Mariche's base rocks in different parts of the planet, was confirmed by specialists at the end of the study.
"The rivers continued to flow until the last geological moment" before the planet became a desert, said the magazine citing a summary of the work of the specialists who have treated the subject.
Since NASA's traveling vehicle, Kyorocyte, made its historic landing in the Gale crater on Mars in August 2012, there is uncertainty about the possibility of water on Mars, even in rare moments.
"We are observing a chemical complex that bears witness to a long history of changes with water on Mars," said John Grotzinger, Koryosite team member and geologist at the Institute of Technology. from California to Pasadena.
