There is a floating spoon in Mars, Curiosity captured a photo of it.
"There is no spoon. This weird Mars feature is likely a ventifact -- a rock shaped by wind," NASA tweeted on Wednesday.
Though looks like real spoon, the most probable explanation is Pareidolia.
Pareidolia is a psychological phenomenon involving a stimulus (an image or a sound) wherein the mind perceives a familiar pattern where none actually exists.
Common examples are perceived images of animals, faces, or objects in cloud formations, the "man in the moon", the "moon rabbit", and hidden messages within recorded music played in reverse or at higher- or lower-than-normal speeds.
