A 350-billion-year-old rock discovered on the Red Planet is “the closest we’ve come to discovering ancient life on Mars,” according to NASA.
Potential signs of microbial life were found in a rock sample collected by the rover in 2024 from an ancient dry riverbed on Mars’ Jezero Crater — an area of rocky outcrops on the edges the Neretva Vallis, a river valley carved by water rushing to the canyon billions of years ago, NASA officials announced in a press conference on Wednesday.
