In 2003, scientists found Chile's Atacama desert so dry it had no detectable DNA. Now it's helping prepare for Mars missions

Chile's Atacama Desert serves as Earth's closest Mars analogue due to its extreme dryness. This arid environment, with minimal rainfall and biological activity, aids planetary research. Scientists study its soil chemistry and extreme conditions to prepare for Mars missions. Discoveries there have refined strategies for detecting life on the Red Planet. The Atacama Desert continues to be a vital natural laboratory for space exploration.
