Here is another great view of the first two holes ever drilled on Mars, by the Curiosity rover. The first one, top, was made on sol 180 (February 6, 2013) and the second one, below, was made on sol 182 (February 8, 2013). The second one is deeper, and some of the powdered bedrock sample obtained will be delivered to the CheMin and SAM laboratory instruments for analysis. The grey material is powdered bedrock (not covered by reddish Martian dust) which has spilled out during the drilling.
