Life on Mars is ‘similar to Chilean desert’ Ananova

Scientists say one of the Earth’s most inhospitable corners has soil very similar to that on Mars. The arid and almost lifeless Atacama desert in Chile could help researchers design better experiments for detecting Martian life. An international research team headed by Rafael Navarro-Gonzales of the University of Mexico compared findings from soils in the Atacama with results of similar tests from the Viking missions to Mars in the 1970s.
