In Scientific American today, Caleb A. Scharf blogs that NASA's Curiosity rover is preparing to drill for the first time. The target will be sedimentary rock crossed by mineral-filled veins, as shown in NASA's image. These rocks are suggestive of significant historical water flow across the martian surface. Once Curiosity has performed its task we all will have a new insight into Mars’ deep past. Will it find life on mars? We soon should know.
