  The authors propose a life cycle for Venusian microbes that begins in the lower haze layer where desiccated spores reside in a dormant phase. The spores are transported upward by vertical mixing induced by gravity waves to a habitable layer of temperate conditions. Acting as CCN, the spores become encased in a liquid droplet (mostly H2SO4 with some H2O) and germinate. During months aloft,...

  This research proposes a life cycle for microbial survival in Venus' atmosphere, addressing challenges of persistence. Microbes reside in liquid droplets, protected from atmospheric loss, but descend to uninhabitable layers as droplets grow. They survive as desiccated spores in the lower haze layer, returning to the clouds through vertical mixing. This cyclic process could sustain life in Venus' aerial biosphere under extreme conditions.

  This study revisits the potential for life in Venusian clouds, addressing challenges like acidity, low water content, and nutrient scarcity. It proposes a life cycle where microbes reside in cloud droplets, form desiccated spores upon descending to the lower haze layer, and are transported back to habitable zones to restart the cycle. Spores act as cloud condensation nuclei, enabling survival under extreme conditions.

  Earth's aerial biosphere supports transient microbial life in clouds, contrasting Venus' potential for permanent microbial habitation due to its lack of a habitable surface. The study highlights adaptive mechanisms, including microbial life cycles, droplet colonization, and gravity-wave mixing, for surviving in Venus' clouds. Further research is needed to understand the dynamics and biomass flux in Venus' lower haze layer.
