Curiosity rover discovers traces of ancient water on Mars

NASA Recently, the Curiosity rover discovered some of the most attractive evidence of ancient water on Mars in the form of wavy rocks formed waves.

ripple formed billions of years ago, when liquid water still covered the surface of Mars. Through Mars, from rover Curiosity near Gale Crater to Perseverance in Jezero Crater, probes explore these ancient waterways for information about the geological history of Mars and itspotential for astrobiology. Could there be petrified microbes among all the red stones and dust?

Curiosity began its mission in 2012. in Gale Crater at low altitudes, but is now on Mount Sharp 3a mile-high mountain once covered in lakes and streams. If life ever existed on Mars, from what we know of its presence on Earth, these ancient waterways are a good place to look.

The rover noticed the texture of the rock – small ripples.slightly reminiscent of dried tire treads – in a layer of rock on Mount Sharp called Marker Bend, according to NASA release.

“This is the best evidence of water and waves we’ve seen on the entire mission,” Ashwin Vasawada, Curiosity Project Scientist at NASA’s Jet Propulsion Laboratory in Southern California, said in a press release.. “We’ve traversed thousands of feet of lake sediment and have never seen evidence like this – and now we’ve found it in what we expected to be dry.”

The marker strip and its surroundings formed in a drier climate than the areas through which Curiosity has already passed. In other words, the NASA team calculated that the water on Mars may have already disappeared by the time the currently studied rock formed. Eat ice sheets and ice caps at the poles of MarsAnd meteorite impacts on the planet lifted underground icebut liquid water been on the planet for billions of years, at least as far as we know. Mars is cold and has a thin atmosphere, so water freezes on its surface. and it is believed that the planet’s ancient water was mostly lost to space. (at least 87%, according to NASA).

The marker tape is so hard that Curiosity was unable to take his sample even after several drilling attempts, but if the rover cannot take a sample from the softer rock, it there is still an exciting vcomes forward.

In the Martian valley Gediz Vallis there is a lot of rock debris, which, according to scientists, were blown there by ancient landslides. This makes the valley a repository of rocks from Mount Sharp, areas that Curiosity cannot access. By examining these boulders, scientists will gain insight into otherwise inaccessible stories from Mars’ past.

While the newly discovered water ripple is one of the clearest evidence of ancient water on Mars, it is unlikely to be the first. Click to see more images that show how water has shaped the Martian landscape.
