The NASA Mars rover Curiosity recently drove within a shallow depression called “Yellowknife Bay,” providing information to help researchers choose a rock to drill. Using Curiosity’s percussive drill to collect a sample from the interior of a rock, a feat never before attempted on Mars, is the mission’s priority for early 2013. Yellowknife Bay is within a different type of terrain from what the rover has traversed since landing last August.
