The MythBusters chose Marshall as one of several NASA locations for an episode to debunk the notion that NASA never landed on the moon.
The cast conducted tests involving a feather, a weight, a lunar soil boot print, and a flag in a vacuum. A team of Marshall scientists helped with the tests.
The MythBusters built a small scale replica of the lunar landing site with a flat surface and a single distant spotlight to represent the Sun. They took a photo and all the shadows in the photo were parallel, as the myth proposed.
They then adjusted the topography of the model surface to include a slight hill around the location of the near rocks so the shadows fell on a slope instead of a flat surface. The resulting photograph had the same shadow directions as the original NASA photograph from Apollo 14.
To test this, they built a much larger scale (1:6) replica of the landing site, including a dust surface with a color and albedo similar to lunar soil.
The MythBusters then took a photograph which was nearly identical to the original NASA photo from Apollo 11. The MythBusters explained that the astronaut was visible because of light being reflected off the Moon’s surface.
