Today, we know Mars as a cold and dry desert, with stains of underground ice and Ice caps In columns. Billions of years ago, liquid water flowed freely across the planet. While people are different Mars Rover I discovered signs of such water once MarsPerhaps there is no better evidence for a shallow lake free of ice than these two groups of ripples in Mars’s rock music.
In November 2022, NASA Curiosity Rover She photographed the Amapari mark bar at the Svouh of Mount Sharp, located in the Gale Crate. Inside the signs itself – a thin layer of rocks – scientists got acquainted with wave ripples in what would have been a sandy line. A few weeks later, the curiosity photographed another group of wave ripples in the bump of ingenuity, which was on the lake bed.
The ripples were believed to have been formed about 3.7 billion years ago, during a period that was believed to be dried. But their presence indicates that the Mars climate was somewhat warm – and its wet surface – at that time. “Caltech” at the post -PhD Institute in California in A. statement. And if the water is detonated by wind, this means that it was not covered with ice, as some scholars assumed.
Of these ripples, the researchers not only determined the presence of a shallow lake here, but also its depth. Using a computer model, Professor Caltech in Geology Michael Lamb found that the size and spacing of ripples indicate that the lake was less than six feet (two meters).
These ripples were filmed with curiosity on the Sol 3684 (December 16, 2022). | Credit

“Previous tasks, starting from an opportunity In 2004, ripples were formed by water flowing across the surface of the old Mars, but it was certain whether this water was ever assembled to form shallow lakes or seas. The previous project world For the task of curiosity, he said in the statement. “The Curiosity Rover discovered evidence of the old long -standing lakes in 2014, and after 10 years, the curiosity discovered the old lakes that were empty of ice, providing an important view of the early planet climate.”
A paper was published on the discovery in the magazine Science progress On January 15.
