The basic template of the conspiracy theory is that NASA couldn’t manage to safely land a man on the moon by the end of the 1960s as President John F Kennedy had promised, so it only sent astronauts into Earth orbit. Conspiracy theorists then argue that NASA staged the moon landings in a film studio and that there are tell-tale signs on the footage and the photos that give the game away. They claim that NASA has covered up the elaborate hoax ever since.

Moon landing sceptics point to supposed clues such as photos that appear to show the astronauts in front of cross hairs that were etched on the camera glass, or a mysterious letter C visible on a moon rock. These and many other seeming anomalies have  purportedly been debunked, but moon landing conspiracy theories have persisted in the popular imagination. Currently as of 2021 as many as 64% to 91% of Americans believe that the moon landings were faked in some way.
