Six Years on Mars, Lecture by Andrew Knoll December 10, 2009

Harvard biologist Andrew Knoll hasn’t actually been to Mars, but he has spent a lot of time examining its rocks, including four-billion-year-old salt deposits investigated by the rovers Spirit and Opportunity. Knoll will reflect on six years of NASA Mars Rover exploration; what the evidence tells us about the history of water and its implication for life on the ancient surface of the Red Planet. Free and open to the public in the Geological Lecture Hall, 24 Oxford Street.
