A clue to ancient life? What scientists found inside Mars’ frozen vortex

Mars’ north polar vortex locks its atmosphere in extreme cold and darkness, freezing out water vapor and triggering a dramatic rise in ozone. Scientists found that the lack of sunlight and moisture lets ozone build up unchecked. This discovery, made with data from ESA’s and NASA’s orbiters, could reveal clues about Mars’ past atmospheric chemistry and potential for life.
