NASA rover finds evidence of once-loud river on Mars

NASAThe car-sized Perseverance rover parachuted into an area of ​​Mars called Jezero Crater, where planetary scientists suspect was once filled with water. Now, two years later, space agency scientists may have found evidence of a “rolling river” once more.

The Guppy Formation, shown in the image below, shows curved rocks—which indicate past vigorous water flow—composed of larger, coarser sediments.

“They indicate a high-energy river that is ‘truckin’ and carrying a lot of debris,” said Libby Ives, a researcher at NASA’s Jet Propulsion Laboratory. is able to move large pieces of material with ease.” said in a statement, “It’s a joy to look at rocks on another planet and see processes that are so familiar,” Ives said.

Scientists had previously observed these curved shapes from space. Six Wheeled Perseverance Rover – A laser-zapping lab on wheels – allowed them to take a closer look.

The mosaic picture shows a field of Mars made up of 203 images stitched together. The curves may result from a shifting river bank, or sandbars may have been eroded down by billions of years of wind-driven sand-blasting. One big question is how this mighty waterway came to be back when mars was a hot, blue planet,

NASA wrote, “Scientists are now debating what kind of powerful flowing water formed those curves: a river like the Mississippi, which snakes across the landscape, or a ridge like the Nebraska Plateau.” braided river, which builds up little islands of sediment.”

In general, there is clear evidence of a past, water-rich world carved into the deserts of Mars. this also includes dried up lakesdry streams, and even ancient Wave’s,

Yet there is zero evidence of life on Mars. Indeed, NASA’s rovers have detected organic material on Mars, which essentially means carbon-like molecules that could make up life as we know it, but nothing that primitive living on the surface could have. suggesting microbes (although the subsurface remains unclear).

A primary mission of the Perseverance rover is to look for signs of life, if it ever existed, however difficult that task may be. A good place to look is in an area that once harbored water – and probably a deep, vigorous river.
