Moon landing conspiracy theories claim that some or all elements of the Apollo program and the associated Moon landings were hoaxes staged by NASA, possibly with the aid of other organizations. The most notable claim is that the six manned landings (1969–72) were faked and that 12 Apollo astronauts did not actually walk on the Moon. Various groups and individuals have made claims since the mid-1970s, that NASA and others knowingly misled the public into believing the landings happened, by manufacturing, tampering with, or destroying evidence including photos, telemetry tapes, radio and TV transmissions, Moon rock samples, and even some key witnesses.
