Curiosity recently sent back a photo from Mars in which you can clearly see a silvery metal object lying on the ground in front of the rover. A discovery that was made when the rover was shoveling sand.
Before you, we go into high gear of alien origin. The probability is very high that the silvery object comes from Curiosity itself. It is probably a screw or a similar object that has fallen off the robot rover itself.
Curiosity has now received new orders to stay at this location and inspect the silver object further.
