When NASA's newest Mars rover, Curiosity, stopped to sample a scoopful of Martian soil its cameras recorded a tiny, shiny object on top of the soil. Another shiny object had been found days before and was identified as possibly a piece of debris that came from the spacecraft. But more shiny objects have been spotted confirming that the newer ones are likely to be native to Mars.
This image shows the three scoop marks made on the Martian surface by Curiosity's digging tool. The second scoopful of soil was discarded after one of the shiny objects was discovered in the sample. The nearest hole on the left was the first sample, the one above it was the second and the one to their right was the third.
