Bad: The program has two segments dealing with what they call ``identical backgrounds''. In one, they show the lunar lander with a mountain in the background. They then show another picture of the same mountain, but no lander in the foreground at all. The astronauts could not have taken either picture before landing, of course, and after it lifts off the lander leaves the bottom section behind. Therefore, there would have been something in the second image no matter what, and the foreground could not be empty. Obviously, the mountain background is a fake set, and was reused by NASA for another shot.

Good: Actually, the pictures are real, of course. As always, repeat after me: the Moon is not the Earth. On the Earth, distant objects are obscured a bit by haze in the air, and we use that to mentally gauge distances. However, with no air, an object can be very far away on the Moon and still be crisp and sharp to the eye. You can't tell if a boulder is a meter across and 100 meters away, or 100 meters across and 10 kilometers away!

That's what's going on here. The lander is close to the astronaut in the first picture, perhaps a 20 or 30 meters away. The mountain is kilometers away. For the second picture, the astronaut merely moved a few hundred meters to the side. The lander was then out of the picture, but the mountain hardly moved at all! If you look at the scene carefully, you'll see that all the rocks and craters in the foreground changes between the two pictures, just as you'd expect if the astronaut had moved to the side a ways between the two shots. It's not fraud, it's parallax!

Another example of the difficulty in estimating distance is due to the shapes of the rocks on the Moon. A rock small enough to sit down on doesn't look fundamentally different from one bigger than your house. Humans also judge distance by using the relative sizes of objects. We know how big a person is, or a tree, so the apparent size of the object can be used to estimate the distance. If we don't know how big the object is, we can be fooled about its distance.

For an outstanding example of this, take a look at video taken during Apollo 16. There is a boulder in the background that looks to be about 3 or 4 meters (10-13 feet) high. About 3/4 of the way through the segment the astronauts walk over to it. Amazingly, that boulder is the size of a large house! Without knowing how big the rock was when we first see it, we have no way to judge distances. That huge rock looks like a medium sized one until we have some way to directly judge its size; in this case, by looking at the tiny astronauts next to it. [My thanks to Bad Reader Martin Michalak for bringing this video to my attention. My very special thanks goes to Charlie Duke (yes, the Charlie Duke, Apollo astronaut and lunar lander pilot) who emailed me (!) about the difficulty in judging distances due to not knowing the sizes of rocks.]

I will admit the Fox program had me for a while on this one; I couldn't figure it out. But then I got a note from Bad Reader David Bailey, who set me straight. However, the producers of the show should have talked to some real experts before saying such a silly thing as this. If they had checked with the folks who run the Apollo Lunar Surface Journal, for example, they would have been set straight too.
