Data gathered by NASA's rover Perseverance has confirmed the existence of ancient lake sediments deposited by water that once filled a giant basin on Mars...
NASA's Perseverance Mars rover is seen in a "selfie" that it took over a rock nicknamed "Rochette\ By Steve Gorman LOS ANGELES (Reuters) - called Jerezo Crater, according to a study published on Friday. The findings from ground-penetrating radar observations conducted by the robotic rover substantiate previous orbital imagery and other data leading scientists to theorize that portions of Mars were once covered in water and may have harbored microbial life. The research, led by teams from the University of California at Los Angeles (UCLA) and the University of Oslo, was published in the journal Science Advances. It was based on subsurface scans taken by the car-sized, six-wheeled rover as it made its away across the Martian surface from the crater floor onto an adjacent expanse of braided, sedimentary-like features resembling, from orbit, the river deltas found on Earth. Soundings from the rover's RIMFAX radar instrument allow scientists to…
