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.
