** FILE ** This image released by NASA on Monday, May 20, 2013, shows a hole in a Martian rock drilled by the NASA rover Curiosity on May 19. It’s the second drilling by the spacecraft since landing in August 2012. Curiosity used the Mars Hand Lens Imager (MAHLI) camera on the rover's arm to capture this view of the hole in the rock, dubbed "Cumberland." The diameter of the hole is about 0.6 inch (1.6 centimeters), the depth about 2.6 inches (6.6 centimeters). In the coming days, Curiosity will transfer the rock powder to its onboard instruments to analyze the chemical makeup. (Associated Press/NASA/JPL-Caltech/MSSS)
