For over two decades, NASA’s Mars exploration has predominantly focused on water, which could unintentionally lead us to overlook other potential forms of life.
Our failure to fully understand the diverse conditions that support life may have led to the tragic irony of mistakenly killing the only life we may have found on Mars.
The natural history of Mars reveals a shift from water-rich environments to extreme aridity, necessitating new strategies for identifying life that can survive under such conditions.
Studying extreme environments on Earth, like the Atacama Desert, helps shed light on how life adapts and survives in increasingly harsh conditions, informing our approach to Mars exploration.
