Re: Moon landings a hoax?

1. Apollo 14 astronaut Allen Shepard played golf on the Moon. In front of a worldwide TV audience, Mission Control teased him about slicing the ball to the right. Yet a slice is caused by uneven air flow over the ball. The Moon has no atmosphere and no air.
Again, aristotle-type physics!
Angular momentum -- the momentum of an object spinning on its own axis can influence the 6 degrees of freedom of any object, vacuum or air.
The study of angular momentum almost kicked my ass in Dynamics (Engineering Mechanics: Dynamics), but it ended up being my strongest suit when I was done.
Had I not left dreaded Dynamics until the end of my college studies, I might have switched ME (Mechanical Engineering) instead of EE (Electrical).
This is stuff that is changes of rates upon changes of rates upon changes of rates and really requires 3 semesters of calculus to understand and explain.

2. A camera panned upwards to catch Apollo 16's Lunar Landerlifting off the Moon. Who did the filming?
It was a remote controlled camera with uplink.
The operator had to send the commands 2 seconds before the launch.
In fact, for Apollo 16, the controller did NOT time it well.
But for Apollo 17, he did a heck of a job and got it right -- and we was soundly rewarded.
Had we had the control systems technology back then that we do today, it would have been easy.
But back then, everything was manual and the human error element was a BIG factor!

3. One NASA picture from Apollo 11 is looking up at Neil Armstrong about to take his giant step for mankind.
The photographer must have been lying on the planet surface.
If Armstrong was the first man on the Moon, then who took the shot?
Early LIMs had a 70mm lunar surface camera that was deployed shortly after touchdown.
That wasn't much of an engineering feat at all, even without the digital control systems technology at that time.
I can't believe you think you need a physical person to run a camera.
Do some research on the Grumman Lunar Module and you'll find it's basically a super Swiss Army box when it comes to attached peripherals and components.

4. The pressure inside a space suit was greater than inside a football.
The astronauts should have been puffed out like the Michelin Man, but were seen freely bending their joints.
Ummm, sorry, but you're pretty ignorant here.
First off, sea level atmosphere pressure is around 15 psi.
Secondly, you have to concern yourself with how much oxygen is in the air (around 15-20%), because your ability to breath is related to the pressure and oxygen mix.
Now let's discuss.
Vacuum is (virtually) 0 psi.
With a 100% oxygen mixture, 5 psi is more than adequate to allow normal breathing.
That's what the astronauts use in a vacuum.
During the "plugs out" test on the Earth, astronauts test the pressure of their vehicle or space suits in a +5psi, or 20psi.
The differential is the same as in a vacuum.
Now if you want to experiment, fill a baloon and test it so it is 20psi.
Then see if you can bend it.
I think you'll be very surprised.
The INCORRECT analysis people do is assume that astronauts use +15psi in space.
In that case, yes, it would be somewhat like inflating a tire to 30psi in the 15psi atmosphere.
Then again, vulcanized ruber at 15psi (+0 psi) isn't the easiest to bend, a heck of a lot more difficult than simple fibers of a 2-layer space suit.

5. The Moon landings took place during the Cold War.
Why didn't America make a signal on the moon that could be seen from earth?
They did, they put reflectors on the moon.
And the descent modules can be seen with optics from the earth.
In fact, I think Grumman-NASA should have done more with the LIM's descent module, as it has an RTG power source.
It could power something for decades.

The PR would have been phenomenal and it could have been easily done with magnesium flares.
Unfortunately putting such materials on a space vehicle would have put up a huge ass flag early in design.
Even the propellent used exoatmosphere cannot combust without the oxidizer, and the chemicals used are so stable without the other.
Even explosive bolts are frowned upon anything that is not part of the initial launch vehicle (booster).

6. Text from pictures in the article said that only two men walked on the Moon during the Apollo 12 mission.
Yes, the LIM Pilot and Commander are in the LIM while the 3rd crewmember remains in the Command Module in lunar orbit.
Yet the astronaut reflected in the visor has no camera. Who took the shot?[/QUOTE] Who says? Do you have a picture?
The Apollo 12 crew did a LOT that was not approved, and I'm sure their use of a camera not designed for a vacuum made it a bit smaller.
I'd have to see the picture.

7. The flags shadow goes behind the rock so doesn't match the dark line in the foreground, which looks like a line cord.
So the shadow to the lower right of the spaceman must be the flag.
Where is his shadow?
It might be due to a reflection on the LIM, and he is much closer at a different light vector than the flag.
Again, I'd have to see the picture to analyze it.
And why is the flag fluttering if there is no air or wind on the moon?
Again, I have explained this over and over.

8. How can the flag be brightly lit when its side is to the light?
And where, in all of these shots, are the stars?
Low resolution camera might be your answer on the stares.
As far as the flag, if it was mylar (which is very light so it is often used as a "generic material" in space), it's reflectivity is the answer on its brightness.
[ SIDE NOTE: We use mylar balloons as decoys in missile defense testing because it's so damn reflective.
Our tracking systems technology today is damn good at seeing right past them. ]

9. The Lander weighed 17 tons yet the astronauts feet seem to have made a bigger dent in the dust.
That's because the descent engine blew all the loose powder that then encircled the craft which the astronauts stepped in.
amstrad said:
The powerful booster rocket at the base of the Lunar Lander was fired to slow descent to the moons service.
Yet it has left no traces of blasting on the dust underneath.
It should have created a small crater, yet the booster looks like it's never been fired.
No, that's not true at all.
After the loose power was blown away, the moon's surface is rocky.
As I mentioned in another thread, at 17 tons in 1/6th Earth gravity, less than 3 tons of thrust would be necessary to offset its weight during landing.
The DC-X (Delta Clipper demonstrator) was of equal weight, but was operating on the Earth and its 6x thrust did NOT blast holes in the Earth when it landed.
Again, elementary physics dismisses the majority of your comments here.
I'd have to see the photos to explain them.
Understand that space, on the moon's surface, you have multiple, very bright light sources -- not only the Sun, but the Earth, and then the massive reflectivity of mylar and other materials on the LIM.
