This image released by NASA shows the view of Curiosity’s planned first drilling site. The six-wheel, nuclear-powered rover landed five months ago on a mission to study whether Mars was habitable. Engineers are preparing Curiosity to drill into its first Martian rock. The enlargements of rocks seen on the right, and denoted by letters and boxes within the left image, represent this diversity. Each box is about 9 inches (22 centimeters) square. (AP Photo/NASA)
