There is no air on the moon. How did the United States fly back to the moon?

On earth, rocket launch needs to be completed at the rocket launch station, but when Americans manned the moon, there was no rocket launch base on the moon. How did they come back? To tell the truth, this is really puzzling, especially the rumors of the fake landing on the moon in the United States, which makes people question the fraud in the United States. In fact, it is true that the United States landed on the moon, but it does not need a launch station to return to the moon.

Apollo's lunar module! Everyone seems to be a whole, but it is actually divided into two parts. Up and down, you can divide them into two modules, and both of them are equipped with engines and fuel tanks respectively. After the lunar orbit was separated from the service module, the downgrader was the basic engine and landed on the lunar surface after ignition. After completing the task, the upper and lower parts of the upgrade are separated and the engine is ignited.

The spacecraft returning from horizontal landing is also a winged spacecraft, the most typical of which is the American space shuttle. Its shape is similar to that of an airplane, and it can achieve horizontal landing. This landing mode has the smallest overload (about 1.5g) and is the most comfortable landing mode for astronauts. Moreover, the space shuttle has strong control ability and high landing accuracy, and can land on the designated airport runway and be reused.

In fact, the United States does not need a rocket launching station to return to Earth on the moon. Why do you say that? This is because the escape speed of the moon =2.38km/s, which can be completed without rocket boost.

First, let's analyze why the moon can escape from the moon when it reaches this speed.

?

escape velocity

We know that the reason why apples fall on the earth is because of gravity. The direction of gravity is actually the interior of the earth. If an object wants to get rid of the gravity of the earth, it needs extra force to fight gravity.

?

For example, if I throw an apple, it may be thrown to a certain height, and then it will fall because of gravity.

?

However, if my strength is very great and the speed of the apple I throw reaches a certain high speed, then the apple may never fall, because the earth is an approximate circle, and the ground level of the apple will drop accordingly. This speed is the first cosmic speed.

If my strength is greater and the speed of the apple thrown out is higher, then the apple may break away from the gravity of the earth and rush into the sky. This speed is the escape speed.

The escape speed of each planet is different, and the specific factors are related to the mass of the planet, while the mass of the moon is smaller, so the escape speed is smaller, and it only needs to reach 2.38km/s to escape from the moon.

How did the Apollo lunar module reach the escape speed?

Let me show you the structure of Apollo spacecraft: flight module, service module, command module and lunar module in ascending and descending stages. The service module and the command module will not enter the surface of the moon, but stay in the orbit above the moon for standby. The lunar module will enter the surface of the earth.

?

When landing on the moon, the descending part of the lunar module will ensure the spacecraft to land smoothly. After successfully landing on the moon, the astronauts will descend from the lunar module and reach the surface of the moon.

?

When returning to Earth, the upper part of the lunar module will launch fuel to push the spacecraft up.

?

The lower part of the lunar module is abandoned on the surface of the moon, which can reduce the weight of the spacecraft.

Because there is almost no atmosphere on the surface of the moon, there is almost no air resistance during the ascent of the lunar module. Under the same fuel, the spacecraft will fly faster than the earth and easily reach the first cosmic speed of the moon. At this time, the Apollo spacecraft will revolve around the moon like a lunar satellite.

At this time, in the orbit above the moon, the control module and the service module are already waiting for each other, and the lunar module will be docked with the service module and the command module again.

?

After all astronauts enter the service module from the lunar module, they will abandon the lunar module, leaving only the command module and the service module to continue to return to Earth orbit. At this time, the power supply is provided by the service module.

?

After reaching the earth orbit, the service module has also completed its mission, and then it will abandon the service module and return to the earth's surface from the command module.

The command module relies on the atmosphere and parachutes to slow down, and the ground staff use the calculated landing position to fly at any time to stand by and search for astronauts landing at sea.

At this time, the whole process of the moon landing plan was taken into account.

The moon is a prehistoric man-made civilization

1. Astronomical parameters of the moon.

It's so special to find the moon today. There are many satellites in the solar system in the universe, but the proportion of the moon is unique. Please look at the following data. The diameter of the earth is 12756 km, and the diameter of the moon is 3467 km, which is 27% of the diameter of the earth.

The two satellites of Mars are 0.34% of that of Mars.

Jupiter's largest satellite accounts for 3.5% of Jupiter.

Saturn's largest satellite accounts for 3.75% of Saturn. The diameter of satellites of other planets is no more than 5% than that of their parent stars, while that of the moon is 27%, which shows that the moon is not an ordinary natural celestial body.

The front of the moon always faces the earth.

Satellites of other planets in the solar system do not have this situation.

The orbit of the moon is circular.

Generally, the orbit of natural satellites is elliptical, while the orbit of the moon is circular. Only the orbit of the artificial earth satellite is round.

The earth is a terrestrial planet, so there should be no satellites.

The attraction of the earth to the moon is far less than that of the sun, but the moon is not attracted by the sun and remains in the earth's orbit.

The lunar earthquake test proves that the interior of the moon is empty.

The high-sensitivity seismograph based on the lunar surface in the United States can even record the footprints of astronauts on the lunar surface.

1969165438+1On October 20th, the ascent of Apollo 12 hit the surface of the moon, followed by the lunar earthquake. The moon rocked for more than 55 minutes. The vibration gradually changes from small to large, and it takes about an hour to go through this process.

Apollo 13 astronauts used the third stage rocket of the spacecraft to hit the moon surface by radio remote control. The lunar earthquake lasted for 3 hours and 20 minutes before it gradually ended. Only a hollow sphere will have this form of vibration. Many lunar earthquake tests were carried out, and the lunar surface vibration caused by the largest lunar earthquake lasted for 4 hours. According to the report of the National Aeronautics and Space Administration (NASA), the lunar earthquake research shows that there is a 40-mile-thick "hard layer" inside the lunar shell.

6. The lunar magnetic field test proves that the interior of the moon is empty. Scientific research shows that all celestial bodies in the universe have magnetic fields, while the moon has almost no magnetic fields. All natural celestial bodies have magnetic fields, which are solid like the earth. The moon is completely different.

A scientist from Massachusetts Institute of Technology studied the gravity of the moon and suggested that the interior of the moon might be empty. His research results were published in an international research magazine named Moon. He wrote: "According to the observation of the lunar orbiter, we have gained a lot of knowledge about the moon, especially in gravity. In other words, the interior of the moon is likely

There is a very hard shell inside the moon.

Scientists have found that all craters are "very shallow" from the perspective of meteorite penetration, which proves that there is a hard shell inside.

This is the understanding of empirical science, so how do theologians know it?

Some experts explained that the moon was created by prehistoric people.

At that time, human beings realized the trouble that night brought to people, so they built a moon, which could bring light to the earth at night.

After a long time, all kinds of dust in the universe, including meteorites, hit and covered, forming the moon we see now.

Therefore, the theory of evolution is simply deceptive, and all mysteries are solved by prehistoric civilization reasoning. Science is always a process in which future generations overthrow the previous generation, and the evolutionary hypothesis is too outdated. Welcome to repost.

Take the launch vehicle as an example. The huge flame below the rocket launch did not directly use the air on the earth. Fuel and combustion-supporting materials are directly stored in rockets, unlike airplanes that only carry fuel and need to absorb air. Apollo lunar module also has its own fuel and accelerant.

In space, without oxygen, we can change the state of motion by injecting gas, using the principle of action and reaction and the momentum theorem. An object is stationary or moving in a straight line at a uniform speed without any external force. When a force is applied, a force in the opposite direction will be obtained. In the absence of air, the Apollo lunar module ignited the fuel in the module, and the combustion of fuel and accelerant produced a lot of gas and heat, thus launching the lunar module out of the moon. Although there is no air on the moon, the fuel of the lunar module can produce air. Not only the Apollo lunar module, but all the ancient man-made aircraft in the universe changed their direction by their own "gas". Of course, today's Hall thrusters are not their own gas.

Moreover, the escape speed of the moon is only 2.4km/s, while the escape speed of the earth is 1 1.2km/s, so a "small" lunar module can do it without a huge rocket.

In America, the ability to survive without oxygen is extraordinary.

Flagrantly launched a war of aggression against Afghanistan, which lasted for 20 years on the oxygen-deficient snow-capped mountains.

The U.S. military invaded the South China Sea more than once, and obviously made plans to sink to the bottom of the sea and live with fish and turtles for a long time.

America is not simple, really not simple.

This is really hard to understand without any physical knowledge. Simply put, a launch vehicle is different from the flight of an airplane. Aircraft fly by the thrust of propeller or jet engine and the lift generated by the atmosphere. On the other hand, rockets rely on the principle of conservation of momentum in physics, burning fuel with oxygen and throwing it backward to produce forward speed, which obviously has nothing to do with air.

The end point of science is theology, so don't be a complete scientist. The explanation of science is sometimes wrong, and eventually science approaches theology because of the unreasonable explanation. There is no air on the moon. Spacecraft can take off on the moon. Not only that, the spacecraft can also fly in space, and there is no air in the vacuum space. Scientists explain the action and reaction of overcoming the constraint of gravity and pushing the air on the earth to make the aircraft leave the earth. But the moon and space have no air to push what? But it did push the spacecraft forward, indicating that the spacecraft pushed some substances, but science does not allow any substances to exist in a vacuum. If the vacuum is filled with material science, many theorems will be rewritten. From the above, we can draw several conclusions 1: scientists don't pretend to understand, 2: scientists are hiding some facts, 3: scientists are making fakes, and 4: scientists are theologians.

He didn't drink soup near the moon at all, just left the things on those spaceships on the moon. Before he fell, he let Yuerang and Lunatone fight back, and almost couldn't return to Earth. And thank those things that fell on the moon for saving them.

Is there air when flying to the moon? If there was air all the way, there would be no moon.

In fact, we find that the conclusions in modern physics are not necessarily correct. There is no air on the moon, which is wrong. There is no absolute vacuum, but it can't be achieved with the existing technology of mankind. Space is a gas, including endless stars such as the earth hanging in mid-air and not falling. In fact, there are many complicated changes in gases to support them.
