At 4:30 on November 24, 2020, my country used a " Long March " No. 5 carrier rocket to successfully launch the "Chang'e" No. 5 lunar probe at the Wenchang Satellite Launch Center in Hainan. At present, "Chang'e" 5 has completed the "earth" work on the moon, and the returner has also rendezvous and docked with the orbiter, and the journey back to earth is about to begin. The series of actions of "Chang'e" 5 not only affected the hearts of hundreds of millions of people, but also unexpectedly brought the "Apollo" moon landing plan that the United States started in 1961 and officially ended in 1972 into people's attention. People rely on just a few words or personal speculations to conclusively claim that the United States manned a manned moon landing. During this period of time, I will also use some materials to sort out the views in the "moon landing falsification" theory, and explain some views by the way.
■ The details of the spare wheel of the American lunar rover, the tread is composed of "herringbone" titanium inlaid in galvanized steel wire mesh.
Question 1: The American lunar rover uses pneumatic tires. Since there is no atmospheric pressure on the surface of the moon, an excessive pressure difference between the inside and outside of a pneumatic tire will definitely cause a puncture.
Popular science: You can find the wheel information of the lunar rover when landed on the moon through the National Air and Space Museum website. The picture above shows the spare tire and fender of the Lunar Cruiser (LRV). The LRV was deployed on the moon during Apollo 15, 16 and 17. The tire is made of woven galvanized steel wire mesh, with a titanium tread riveted to it in a herringbone shape. This mode prevents the wheels from sinking into the soft lunar soil. Facts have proved that the lunar soil is harder than expected, leaving traces about 1.27 cm deep on the tread after the wheels passed. The tire was transferred from the Alabama Space and Rocket Center to the National Air Museum in 1975.
■The spare wheel of an American lunar rover looks like a pneumatic tire from a distance.
It can be seen from the appearance that the lunar rover’s tires are distinct from the outside to the inside. The titanium pieces that are in contact with the moon are composed of "human"-shaped titanium pieces. These titanium pieces are inlaid on the galvanized steel wire mesh. Ring the metal ring, and finally the inner hub. This design can play a certain role in damping, and the "herringbone"-shaped titanium sheet can increase the contact area, thereby reducing the depth of the tire into the lunar soil.
Question 2: When the American astronaut was driving the lunar rover, dust was raised near the tires. The gravity of the moon is only 1/6 of that of the earth, and it is in a state of no wind. The dust cannot float like on the earth.
■ In 1969, the American "Apollo" 11 landed on the moon. Astronauts are setting up ranging laser reflectors and moonshock detectors.
Popular science: As mentioned above, the lunar rover tires have a layer of titanium attached to the surface, but the steel mesh can still contact the surface of the moon when driving. The area where the steel mesh walks will crush the lunar soil and refine it. The reason for the rotation throws up the lunar soil, thus forming a picture of "sand".
Question 3: "Yutu" lunar rover has obvious rut marks and no dust is generated. The traces of the moon on the back of the U.S. lunar rover are not visible at all if you don't look carefully, and a lot of dust is produced.
■The "Yutu" lunar rover walks slowly, and the wheels are hollowed out, with obvious indentations and no dust.
Popular science: The vehicle carried by the detector is usually wheeled, but the specific design depends on the actual situation for analysis. The "Yutu" lunar rover has hollowed out the wheels in order to cross small rocks and other obstacles. The small contact area with the lunar soil will naturally form deeper indentations. In addition, the vehicle speed is very slow, so it is impossible to generate dust. While the US lunar rover has a much larger force area when it is traveling, the dust brought up by the steel mesh when traveling on the moon will further cover up the indentation.
Question 4: Why can't the vast starry sky be captured by taking photos or videos on the moon?
Popular Science: This question is even simpler. Can you try to take a cell phone or camera and use normal mode to capture the starry sky at night when the weather is clear? To capture the starry sky, a long exposure is required. And when "Apollo" landed on the moon on the 11th, the film camera was still used. How can there be time to take an artistic photo of the starry sky?
■ The American flag is creases, not fluttering.
question 5: Why is the American flag "fluttering in the wind"?
Popular science: The American flags of the "Apollo" mission are all made by Anne Banner Manufacturing Company, and the material is rayon. You should have seen flags blown by the wind. The flags are usually wavy when blown by the wind, rather than full of wrinkles. If there is really wind, the dust on the ground will also be blown up.
Question 6: Does the United States really have a giant Saturn 5 rocket?
■ I cannot answer this question.
How can I answer this? Don't answer at all, this kind of question is meaningless at all, just PASS!
Due to space reasons, the science popularization about the "fake" moon landing in the United States is here first. If you have any questions, you can leave a message in the comment area. I will continue to popularize science tomorrow!
