Mysterious ancient mask found on Mars rock

On 2024-04-27 the Chemcam onboard NASA's Mars rover Curiosity captured an intriguing image depicting a mysterious mask adorning a sizable rock on the Martian surface. 


The mask appears to defy natural origins, bearing the hallmark of artificial craftsmanship and deliberate placement upon the rock. 


Is the mask part of an ancient statue, or does it stand alone? What significance might its placement hold, could it represent a sacred relic from an ancient civilization that once inhabited the planet or might the mask serve as a homage to an ancient deity? 

Yet, who created this mask?
