July 1969. Apollo 11. Neil Armstrong steps off the ladder, says the famous line, and plants a flag on the Moon while 600 million people watch live on TV. NASA went back five more times, brought home 382 kilograms of moon rocks, and left mirrors on the Moon that scientists still use to bounce lasers off today.

But ever since, millions of people around the world have believed the landing was staged - pointing to the waving flag, the missing stars, and the Cold War race against the Soviet Union.
