NASA rover Curiosity drills into second Martian rock; prepares to study it in detail PASADENA, Calif. - NASA's Curiosity rover drills again. The space agency said Monday that Curiosity has bored a hole in a second rock and will transfer a pinch of powder to its onboard laboratories later this week for analysis. Sunday's drill was the first major activity by Curiosity since it emerged from a monthlong hiatus. The latest drill site was located about nine feet away from the first rock that Curiosity drilled into three months earlier. A preliminary analysis of the first rock revealed evidence of an ancient environment suitable for primitive life. Scientists wanted to study a second rock to confirm the finding. The team hopes to wrap up soon at the current location and start the long drive to Curiosity's ultimate destination - a mountain rising from the crater floor.
