Three astronauts - Neil Armstrong, Michael Collins, and Buzz Aldrin - launched aboard the Apollo 11 spacecraft on a mission to land on the Moon in July 1969. The 8-day mission was successful, with Armstrong and Aldrin becoming the first humans to walk on the lunar surface. However, some conspiracy theorists argue that the Moon landings were faked and did not actually occur. The document then presents several of the most common arguments made by conspiracy theorists claiming to prove the landings were hoaxed, such as the lack of stars or impact craters in photos, unusual shadows, and mysterious reflections. NASA has provided counterarguments for each of these claims based on scientific explanations.
