NASA finds clearest sign of life on Mars after biological sample breakthrough

NASA has announced it has found the clearest sign of life on Mars.

Dean Duffy, the new NASA administrator, said a sample collected by the Perseverance rover was the "clearest sign of life" on Mars. The sample, called "Sapphire Canyon," was collected back in July last year at a site of rocky outcrops on the edges of Neretva Vallis, a river valley carved by water rushing into Jezero Crater long ago.

NASA officials shared details about the discovery on Wednesday and is the best evidence so far that Mars once harboured life. Since the rover landed on the Red Planet in 2021, it has explored the Jezero Crater, in Mars' northern hemisphere that was once home to an ancient lake.
