Conspiracy Theory: Squirrel had been found on Mars

Sharp-eyed internet users spotted the animal in an official NASA photograph taken by the Curiosity Rover soon after it landed on Mars in 2012.

Conspiracy theorists believe the picture reveals a top-secret NASA experiment which the public were not informed about due to animal rights violations.
