This image was taken by the camera of the Curiosity rover on March 1, 2019, and almost immediately after publication on the network, an anomalous object was seen.
The image is available at the source in two versions, in black and white and in a large color panorama.
Almost in the center of the photograph is a small object, clearly of artificial origin. It looks like a metal piece roughly torn from something.
The detail shows a neat and even round hole as if from a rivet.
According to the first assumption, this may be a part of the rover itself, but it is difficult to say from which part of the rover it flew off, and nowhere was it reported that small parts could fall off from Curiosity.

In addition, as one of the Internet users noticed, there are no traces of the rover around this detail, that is, "Curiosity" did not even drive up to this place.
Without a doubt, this is one of the most intriguing finds in Martian imagery in recent years.
