Curiosity’s finding of strange “floating spoon” on Mars

NASA’s Mars rover Curiosity has recently sent an interesting image of Mars showing a “floating spoon” type of thing on the planet. This floating spoon looks like hovering above a ridge with a shadow on the surface.
This interesting thing was initially observed by members of the UnmannedSpaceflight.com forum in an image taken by Curiosity’s Mastcam on sol 1089 of the mission (Aug. 30). Some experts are of opinion that this spoon is a kind of “pareidolia”, which is a psychological phenomenon for relating a random object or pattern with a familiar object or pattern. It can be a trick of light and probably a rock, which looks like a spoon, is attached to the surface of Mars that is not clear in the photo.
Already, NASA’s instruments have gathered many pareidolia as, for example, “elephant”, “faces”, “rats” and “yetis” on Mars as shown in the figures below:
