In 2012, Curiosity examined the dusty soils that gave it an insight into the processes that drive thedry and cold environment that dominates Mars today.
The effect is achieved by trickling seawater over porous cardboard screens -- called evaporators -- which cool and humidify thedry desert air, creating a favorable growing environment for crops.
In an environment far too dry to sustain much life, the flora and fauna have adapted, enabling them to glean just enough moisture from the ocean fog that spills inland at dawn.
