NASA Rover Finds Possible Biosignature – Closest Hint Yet of Life on Mars In a sensational development for astrobiology, NASA announced that Perseverance has collected a Mars rock sample that “could preserve evidence of ancient microbial life” nasa.gov. The rover drilled the sample, nicknamed “Sapphire Canyon,” from an ancient riverbed formation rich in clay – exactly the kind of environment that on Earth traps and preserves organic remains nasa.gov nasa.gov. Inside the rock, scientists detected certain organic molecules and chemical patterns that are considered potential biosignatures, meaning they might be remnants of past life (though not yet proof of it)
