When astronomers from around the world want a precise measurement, they bounce lasers off of 1 of 3 retroreflectors left on the moon by Apollos 11, 14 and 15. They're exactly where NASA says they should be. Mythbusters demonstrates this before your very eyes. How did they get there? If weren't placed there by Apollo astronauts, then hoax theorists have some explaining to do.
