Did America 1967 land on the moon? Give reasons.

European photographers exposed the fake photos of Apollo landing on the moon by NASA in the United States, which caused many repercussions in society and academia, and it has been debated so far. At present, the online doubts about Apollo's moon landing plan are summarized as follows: 1. The main representative of Apollo moon landing fraud in the United States believes that the basis of Apollo moon landing fraud in the United States is that Apollo moon landing photos are forged. He found that in the photos taken by Apollo 1 1 when people landed on the moon, the incident angle of the sun calculated according to the shadow was obviously inconsistent with the time, coordinate points and moon phase period of astronauts' activities on the moon announced by NASA. For example, he said, "Take Apollo 1 1 as an example. The moon landing point is the sea of tranquility on the moon, 23.5 degrees east longitude and 0.6 degrees north latitude. The launch time from the earth is July 16, 69 GMT 13: 32, and the time for extravehicular activity on the moon is about two and a half hours, from 65438. According to my calculation, the incident angle between the sun and the moon is only 6 to 7 degrees, almost close to the horizon. But the photos of Apollo 1 1 with the American flag on the moon show that the incident angle of sunlight is about 30 degrees, which is too far. " 2. The moon landing video is a fake Apollo moon landing video analysis. Hamlet suggested that astronauts' jumping movements and heights on the surface of the moon were the same as those on the ground. He thinks: "The gravity on the moon is one sixth of that of the earth. Even a fully equipped astronaut weighs only 60 pounds. It should easily jump six times higher and six times farther than the earth. Judging from the video, the astronauts jumped three or four inches off the ground at most, less than one meter away. Isn't that a problem? Someone played back these shots 2.5 times faster, and everything was normal, just like the speed, height, distance and rhythm of jumping in that set of equipment on earth. It is wrong to calculate the acceleration according to the speed displayed by the lens, because the lens is slow. If the lens speed is slowed down to half, the acceleration will become a quarter, and if the lens speed is slowed down to 2.45, the acceleration will become a sixth. Unfortunately, as a result of this treatment, the intensity of astronauts has also become one-sixth. If you really go to the moon, the astronaut will be on the moon, and his thighs should be as strong as the earth. " 3. Questioning the installation of laser mirror denies the laser mirror installed by Apollo on the moon. He pointed out that the laser reflector is another symbol of Apollo's moon landing scam. He said: "... when the laser beam hits the moon, it diverges into a big beam with a diameter of seven kilometers, and when it reflects back to the earth, the diameter of the beam reaches 20 kilometers." According to the mirror photos I saw on the moon, it is estimated that it is no more than one fifth of a square meter. Ok, now please calculate, according to the optimal conditions, that is, the mirror is completely perpendicular to the beam, and the reflectivity reaches 100%. What percentage of the original light beam can be intercepted by the mirror and reflected back? The thickness of this reflected beam after reaching the earth is 20 kilometers. Assuming that the cross section of your receiving device is one square meter, how much of the original light was finally received by you? I don't know, but I am shocked! Also, this mirror is made up of countless small mirrors. How accurate is the collimation of these small mirrors to ensure that the reflected light can enter your instrument instead of running 50 kilometers away? The difference between the gravity of the moon and the gravity of the earth, as well as the huge temperature change day and night, will inevitably cause certain deformation of the mirror. What effect does this deformation have on alignment? You would say, but I did detect reflected light! Good question. You know, your mirror is not the only reflective object on the moon. All the rocks and sand on the moon will reflect light! Now let's calculate the reflection of rocks and sand on the moon. First, the mirror of the moon is big enough to receive all the incident laser beams, and it is 100% reflection, so let's calculate the reflection efficiency of 10% and absorb everything else. This kind of reflection is diffuse reflection, and the direction of the reflected light is uniformly distributed within a hemispherical spherical angle (assuming uniform distribution). How many reflections can a square meter receiver receive on the earth? The calculation results will surprise you. The diffuse reflection of the moon is nearly 100 times stronger than your small mirror! In your detector, there are 100 photons, 99 of which are scattered light from the moon and one is reflected light from your mirror. How do you know which photon it is? How do you know that there are 1% mirrors reflecting light here, but not all of them are reflected by the moon? 4. Questions about Saturn V The Saturn V rocket used to land on the moon is extremely powerful, far exceeding any modern rocket and modern space shuttle. Why is it abandoned now? It is said that even the drawings have not been preserved. Why didn't the basic drawings remain for such a major historical event? The United States has never built an earth space station, and so far there is no suitable vehicle to put the space station into earth orbit. Why? The modern space shuttle only sends a fragmentary payload of no more than 20 tons into low earth orbit at a time. Saturn V was developed in the 1960s. It is said that it is easy to send a load of more than 100 tons into the earth's orbit and send dozens of tons of objects out of the earth's gravitational circle. Launching the space station should be a breeze. If the drawings are still there, it should be easy to use modern computer technology and other high-tech improvements to make more effective and powerful rockets. Why not? NASA thinks Saturn V is too expensive, so it's ok to cheat children. From 1967 to 1972, the United States made 17 Saturn V in one breath. From Apollo 1 to Apollo 17, 17 Saturn V launches all failed. This high reliability is an excellent record in the rocket category, and it is not expensive to manufacture 17 Saturn V in one breath. Why suddenly abandoned? And the lunar module is also very problematic. It is easier to shoot an object on the moon, but it is not so easy to launch it from the moon. Is there enough fuel to make it reach the lunar orbit speed, that is, more than 1.7 km per second? When landing on the moon, the rocket continued to burn twice, once for 30 seconds, slowing down and leaving the orbit of the moon, and once for 12 minutes, to counter the gravity of the moon (I know it is one sixth of the earth! ) until a soft landing is achieved. Will there be enough fuel to launch again? The first stage rocket of Saturn V is kerosene and liquid oxygen, and the second and third stages, as well as the moon landing spacecraft, all use liquid hydrogen and liquid oxygen. It took five days from launch to landing on the moon and then to re-launch. By the last Apollo, it took even longer to stay on the moon, and it took eight days from launch to return. During this period, how to keep the liquid hydrogen on the moon in an ultra-cold state and make the total weight of the lunar module as small as possible is a very difficult technical problem. NASA never talked about how to overcome it! On the issue of project progress, he also said: "From the history of Apollo, the biggest doubt is that the project is progressing too fast, and it is unimaginable to use the power of the United States to pour the power of the whole country." It is particularly important to note that it was not until 1967 1 month that the first Saturn V was successfully developed and the first launch test (Apollo 1) was just about to be carried out. Unfortunately, during the pure oxygen test of the lunar module in 65438+ year1October 27th, the wires collided and caused a fire. Five minutes later, rescuers opened the capsule and all three of the best astronauts were burned. It took three minutes to open the hatch. After the accident investigation, all the wiring hardware of the rocket was redesigned and the wiring was rearranged. The lunar module has also been redesigned, removing the hatch that is difficult to open from the outside. For this reason alone, the hardware development process of the moon landing program was forced to be delayed by 18 months. 1July 969 How is it possible to land on the moon in such a short time? As early as 196A, it was found that the pure oxygen scheme used in the lunar module had serious safety disadvantages and was not suitable for use. Many tests have proved that the spark generated by the friction of the electrical switch in the pure oxygen cabin is easy to cause fire and impossible to put out. Using pure oxygen can reduce the pressure of the lunar module, and the design is simple, but for safety reasons, the design of nitrogen and oxygen mixture is adopted. This greatly increases the design difficulty, because the pressure and proportion of the two gases need to be controlled at the same time, and the weight of the lunar module alone has increased by one ton. The question is, why did you do the pure oxygen test when the 1967 instrument was broadcast live, and let the astronauts sit in it instead of ordinary testers? There was no fuel injected into the rocket at that time, and there was no plan to launch the test. Why don't you take any safety precautions when you know there is danger? It is suspected that the astronauts refused to cooperate in the fake plan and were murdered. According to the published lunar module internal pressure, it is pure oxygen. (It is necessary to ensure that astronauts can breathe the amount of oxygen contained in normal air at normal atmospheric pressure when breathing, so the smaller the pressure, the higher the oxygen content. If it is below a certain critical pressure, pure oxygen must be used. This is very suspicious, because pure oxygen has come to the conclusion that it cannot be used. If mixed gas is used when launching, and then pure oxygen is used, then the cabin must be evacuated and then replaced with pure oxygen, and astronauts must wear spacesuits to evacuate, and astronauts can't suddenly transition from nitrogen-oxygen mixture to pure oxygen, otherwise the nitrogen dissolved in blood vessels will run away, leading to coma ... It is quite difficult to solve such a complicated problem in a small lunar module. "
