Five bites into Mars
Curiosity used a mechanism on its robotic arm to dig up five scoopfuls of material from a patch of dusty sand called "Rocknest," producing the five bite-marks visible in this image from the rover's left Navigation Camera (Navcam). Each of the holes is about 2 inches wide. The fifth hole was dug on Nov. 9, 2012.
