"So, the two key ingredients for photosynthesis can be present within dusty Martian ice in the mid-latitudes," Khuller added."Photosynthesis requires adequate amounts of sunlight and also liquid water to occur. Two previous independent simulations of dense Martian snow found that melting below the surface can occur in the Martian mid-latitudes today if small amounts of dust are present within the snow.
The team thinks that the polar regions of Mars, where the majority of its ice is found, would be too cold for these radiative habitable zones to exist because of a lack of subsurface melting. Such melting would be more likely to occur at mid-latitude areas of the Red Planet.The team's theory has some support, in the form of observational evidence coming not from Mars but from our planet.
Once within the ice every summer, the researcher continued, liquid water forms around the dark dust inside the ice due to heating from sunlight, even if the ice above is frozen, like a lid. This happens because the ice is translucent, allowing sunlight to penetrate below the surface. that live in these shallow subsurface habitats on Earth," Khuller said."The microorganisms typically go dormant in the winter when there is not enough sunlight to form liquid water within the dusty ice.
