LOS ANGELES - NASA’s Perseverance Mars rover has made a remarkable discovery, the agency reported on Wednesday, when scientists discovered the six-wheeled machine has been traversing on the site of an ancient Martian lake where magma once flowed.According to NASA researchers, the rover’s latest findings were "completely unexpected," as it was previously speculated that the land the rover is traveling on was sedimentary, not hardened lava.
When Perseverance first arrived, scientists knew the rover was landing on an ancient lakebed. But they initially thought the material of the land was made up of sediment from rocks and other geological material deposited by the lake.
