NASA has announced the first detection of possible biosignatures in a rock on the surface of Mars. The rock contains the first martian organic matter to be decisively detected by the Perseverance rover, as well as curious discoloured spots that could indicate the past activity of microorganisms. Ken Farley, project scientist on the mission, has…
