Curiosity Digs In (Annotated)

This pair of images shows a "bite mark" where NASA's Curiosity rover scooped up some Martian soil (left), and the scoop carrying soil. The first scoop sample was taken from the "Rocknest" patch of dust and sand on Oct. 7, 2012, the 61st sol, or Martian day, of operations. A third scoop sample was collected on Oct. 15, or Sol 69, and deposited into the Chemistry and Mineralogy (CheMin) instrument on Oct. 17, or Sol 71.

These images were taken by Curiosity's Mast Camera. Scientists enhanced the color in this version to show the Martian scene as it would appear under lighting conditions on Earth, which helps in analyzing the terrain.
