NASA's Perseverance rover finds evidence of ancient river system on Mars

An international research team has discovered evidence of a 4.2-billion-year-old river system in Mars' Jezero crater, according to new analysis of data from NASA's Perseverance rover. The rover, which landed in February 2021, used ground-penetrating radar to reveal geological structures beneath the surface. While researchers cannot determine the exact nature of the river, it likely flowed into a lake within the crater, marking a breakthrough in the search for ancient life on the red planet.
