Chile Desert to Prepare Robot for Life on Mars

Scientists on the prowl for life on Mars have trained their sights on the parched Atacama Desert of northern Chile. Scientists believe that if their high-tech robotics succeed in their quest to find life in the Earth’s most inhospitable deserts, they may also be able to find life on Mars.

David Wettergreen, a research scientist at Carnegie Mellon University’s Robotics Institute in Pittsburgh, Pennsylvania, described the Atacama as “the most arid desert on Earth. It is what scientists call an end member [ecosystem] in that it has the lowest organic content of anywhere on Earth.”
