Wait...So you have done the research, yet you still say that a rocket can NOT work in the vacuum of space.
That would be news to all of the space-faring nations that have controlled craft in space.

I have a very good friend who worked on the saturn 5 rocket project and the landing module, even he believes we never went.

In the vacuum of space there is no matter for the rockets' energy to be transmitted to for thrust. Please.
Imagine the following situation: You are wearing a space suit and you are floating in space beside the space shuttle; you happen to have a baseball in your hand. If you throw the baseball, your body will react by moving in the opposite direction of the ball. The thing that controls the speed at which your body moves away is the weight of the baseball that you throw and the amount of acceleration that you apply to it. Mass multiplied by acceleration is force (f = m * a). Whatever force you apply to the baseball will be equalized by an identical reaction force applied to your body (m * a = m * a). So let's say that the baseball weighs 1 pound, and your body plus the space suit weighs 100 pounds. You throw the baseball away at a speed of 32 feet per second (21 mph). That is to say, you accelerate the 1-pound baseball with your arm so that it obtains a velocity of 21 mph. Your body reacts, but it weighs 100 times more than the baseball. Therefore, it moves away at one-hundredth the velocity of the baseball, or 0.32 feet per second (0.21 mph).

The ISS employs a total of four CMGs as primary actuating devices during normal flight mode operation. The objective of the CMG flight control system is to hold the space station at a fixed attitude relative to the surface of the Earth. ...... CMGs absorb momentum in an attempt to maintain the space station at a desired attitude. The CMGs may eventually saturate (absorbing momentum to the point where they can absorb no more), resulting in loss of effectiveness of the CMG array for control. ....
(**) You should watch the video at the end....over 30 minutes, but VERY informative about orbital mechanics....reality and science that is useful to learn.
The Apollo Suits
Each of the suits, together with the backpack comprised what was virtually an independent spacecraft - lacking only an engine. The suit-and-backpack combination - called the Extravehicular Mobility Unit or EMU - kept him safe from the lunar vacuum, kept him cool by getting rid of excess body heat, provided him with oxygen for breathing, removed the carbon dioxide he exhaled, and gave him the means to talk with his crewmate and, through relays in the LM and on the Lunar Rover, the means to talk with Earth. The suit was also designed so that, despite the tendency of internal pressure to make it a rigid, unyielding balloon, the astronaut could move his arms and legs and flex his fingers. Necessarily, moving the suit against the internal pressure was hard work. Forearm fatigue from the constant use of the hands inhibited productivity, but at least it was possible to get work done......
Next to his skin, the astronaut wore a Liquid-Cooled Garment (LCG), a pair of 'long johns' embedded with a network of thin plastic tubes. The suits were made of an inner bladder covered by several layers of insulating aluminized Mylar which, collectively, not only held pressure but also provided thermal protection when the astronauts were out in the direct sun. In addition, the outer layers of the suits were strong enough to resist tearing and abrasion as the astronauts crawled in and out of the LM, carried equipment, jumped onto their Rover seats, brushed up against rocks, and sometimes even fell. At stomach and lower chest levels, the suit was equipped with connectors for water hoses, oxygen hoses, and a communications cable. The hose connectors each had a ring lock and, embedded in it, a ring-locking mechanism ingeniously called a "lock-lock". There were also dust covers over each of the connectors....
The hoses ran from the connectors around to the backpack or PLSS (Portable Life Support System) - pronounced "pliss" - which contained communications and telemetry gear, tanks of oxygen and feedwater, a fan to move the oxygen through the suit, a pump to move the closed-loop water through the Liquid Cooled Garment,
Indeed, the astronauts could divide their lunar stays into something resembling three normal 24-hour days - four hours of EVA preps, eight hours of work outside the spacecraft, four hours of post-EVA activities, and eight hours of rest - and, thereby, minimize the fatigue and stress with which they had to cope

Did anybody read the story at the OPs link, From what I read, Godwin says he has explanations for the anomolies in the Moon Landings.
But his strongest argument is that all Apollo missions were tracked by the Jodrell Bank Observatory in England, a privately owned facility — and the Russians.
"If anybody had a vested interest in saying it was faked, you'd think it was them," he said.
"Even the Russians sent letters of congratulations saying: 'Well done'!"
Peace

Ha ha, yea, thsi conspiracy has been around for a while now. I think there's probably more evidence that it was fake now then that it was real. =9 Heck, for all we know, the moon may be something likely completely different from anythign in those recordings/photos. Don't you think it would be extremely hot with no atmosphere especially in those suits? You'd think they'd start getting burned with minutes or even seconds (despite the white color of the suit and/or tinted face shield). I didn't hear any reports of it being hot there or of any even small sun burns. =9
