A NASA study suggests that traces of ancient life could be locked in Martian ice. Lab tests freezing bacteria under Mars-like radiation revealed amino acids can persist for tens of millions of years. Researchers say pure ice offers protection, making Mars’ frozen regions ideal for searching preserved biomolecules.A NASA study suggests that traces of ancient life could be locked in Martian ice.
