Phil Plait is the astronomer who made the BadAstronomy website that goes and denounces myths about space...
- no impact crater around the moon lander
Bad: In the pictures taken of the lunar lander by the astronauts, the TV show continues, there is no blast crater. A rocket capable of landing on the Moon should have burned out a huge crater on the surface, yet there is nothing there.
Good: When someone driving a car pulls into a parking spot, do they do it at 100 kilometers per hour? Of course not. They slow down first, easing off the accelerator. The astronauts did the same thing. Sure, the rocket on the lander was capable of 10,000 pounds of thrust, but they had a throttle. They fired the rocket hard to deorbit and slow enough to land on the Moon, but they didn't need to thrust that hard as they approached the lunar surface; they throttled down to about 3000 pounds of thrust.
Now here comes a little bit of math: the engine nozzle was about 54 inches across (from the Encyclopaedia Astronautica), which means it had an area of 2300 square inches. That in turn means that the thrust generated a pressure of only about 1.5 pounds per square inch! That's not a lot of pressure. Moreover, in a vacuum, the exhaust from a rocket spreads out very rapidly. On Earth, the air in our atmosphere constrains the thrust of a rocket into a narrow column, which is why you get long flames and columns of smoke from the back of a rocket. In a vacuum, no air means the exhaust spreads out even more, lowering the pressure. That's why there's no blast crater! Three thousand pounds of thrust sounds like a lot, but it was so spread out it was actually rather gentle.
[Note added December 6, 2001: Originally in this section I said that the engines also cut off early, before the moment of touchdown, to prevent dust from getting blown around and disturbing the astronauts' view of the surface. This was an incorrect assertion; it was known that dust would blow around before the missions were launched, and steps were taken to make sure the astronauts knew their height above the surface. Anyway, the incorrect section has been removed.]
- no dust on the lander footings
No air on the moon. Only dust touched would be from the exhaust of the lander. Dust does not travel in a vaccuum and moon gravity like it does in air and earth's gravity.
- footage which was supposedly taken on different days in different places having identical landmarks
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!
- when moon walk footage is sped up in appears as if it is someone walking in full gravity
If you watch the clip, you will see dust thrown up by the wheels of the rover. The dust goes up in a perfect parabolic arc and falls back down to the surface. Again, the Moon isn't the Earth! If this were filmed on the Earth, which has air, the dust would have billowed up around the wheel and floated over the surface. This clearly does not happen in the video clips; the dust goes up and right back down. It's actually a beautiful demonstration of ballistic flight in a vacuum. Had NASA faked this shot, they would have had to have a whole set (which would have been very large) with all the air removed. We don't have this technology today!
I hope that helped...
The biggest problem with the propagation of these bullshit ideas of not landing on the moon are largely based on the assumption that the moon has the same properties of the earth. The astronauts were not on earth. They were on the moon, and we can see that in the physics of motion in the videos and the physics of light and whatnot in the pictures.
