Extended between Chile and Peru, Atacama is the world’s driest non-polar desert and arguably the closest to the conditions on the red planet, according to their work published in the journal Proceedings of the National Academy of Sciences (PNAS).
When it started to rain, scientists detected an explosion of biological activity in the earth, which could help scientists search for signs of life on Mars.
