Does China have to become a superpower to have the ability to land people on the moon? 5

Is there a necessary connection between whether or not there is a manned lunar landing and whether or not there is a superpower? It should be said that after China has the ability to carry people to the moon, it is one step closer to a superpower.

No, it's that the moon landing is not worth much now, the cost is too high, and the cost performance is low.

En, society is developing rapidly, and plans can't keep up with changes, who knows.

Reason:

One is expensive: today's rockets can be commercially leased, and the first time when leasing is often in grams, and each gram is expensive. A person weighs about 60 kilograms, and in addition to this, they have to eat and drink water in space, which will be calculated into a lot of costs, so the manned lunar landing program will be launched.

Very expensive. The second reason is unsafe: the machine is not only lighter, but also safer. Even if the mission fails, there will be no injuries to the astronauts.

The third reason is that it is not necessary: according to China's scientific research capabilities at this stage, we can also send humans to the surface of the moon as long as we want. But what humans can do, machines can replace, so there is no need to launch astronauts to the surface of the moon.

In the past 20 years, China has completed six lunar exploration programs.

And many times set world firsts, such as: Chang'e-4.

The first landing was on the far side of the Moon.

Antarctica-Aitken Basin. The reason why this is the case has a lot to do with the improvement of China's economic strength.

1. Our technology is not good enough.

At present, China's lunar orbital capacity is the second largest in the world after the United States, and Chang'e-5 is also the world's heaviest unmanned lunar probe to date. But the Apollo spacecraft still weighed five times as much as Chang'e-5. Of course, the moon landing can also use the method of multiple launches of combined spacecraft, Russia once had a lunar landing program, which required seven launches, and we can do this method, but it is too complicated, and the probability of failure is too high to be necessary.

Therefore, at present, it is impossible to achieve a manned landing on the moon with the Long March 5.

At present, China's lunar landing program is a two-legged walk, one is the Long March 9 program, which is similar to the Apollo program, and it will land directly on the moon with one launch. The other is the 921 rocket program, which was launched in two phases and landed on the moon after a combination of lunar orbits. The engines of the 921 rocket are basically ready-made, so the progress is faster.

Since the Long March 9 will launch a heavy-duty space station module in the future, it will not stop even if it is not needed to land on the moon.

2. Money can't be spent like this.

The money spent by the Apollo program was enough to build several hundred aircraft carriers at the time. For China now, there is no need to burn money like this, since it can't burn money, then it can only be done slowly. Not only can we not burn money, but we also have to find a way to make money for the space industry.

In fact, if we launch a rocket, we can earn tens of millions at most, dozens of rockets a year, and more than 100 million. Feed hundreds of thousands of people in the industry? The space industry has always been supported by state finances.

In recent years, China has begun to develop private aerospace, using private funds to develop aerospace technology, and generating profits through aerospace technology. This is the long-term future of this industry. However, the development of private aerospace enterprises has withdrawn a large number of professional talents, which inevitably affects the scientific research progress of the national team.

So we can see in the first data that a large number of technicians were very young when the Long March rocket was launched, at best it is our young talents, but at worst it is that mature technicians cannot be retained. It is also a necessary price to pay for our space industry.

3. We are not in a hurry.

Looking ahead, it is unrealistic to catch up with and surpass the United States in a short period of time, and looking backwards, it is unrealistic for other countries to catch up with and surpass us in a short period of time. We will not be in a hurry to carry out the moon landing plan for ten or eight years. According to the current public plan, the timing of our moon landing is roughly scheduled before 2030.

Our country has the ability to land people on the moon.

However, we do not have the strength, because what we lack most in China is the thrust of the rocket, and what we lack is a heavy rocket with a low-earth orbit capacity of 140 tons.

When will China be able to land a man on the moon? In fact, it could have been done a long time ago, and scientists tell the truth.

China has not yet landed on the moon, and the first and only country in the world to have ever had an astronaut on the moon is the United States.

October 4, 1957, former Soviet Union.

Launch of the world's first artificial Earth satellite.

On July 20, 1969, the Apollo lunar module landed on the surface of the moon and began the first lunar landing in human history.

From manned spaceflight to manned lunar landing is a very complex system engineering, there are many technical problems to be overcome, and China still needs to break through a series of difficulties, such as the astronauts' exit from the capsule, the docking of spacecraft, the development of high-thrust rockets, and so on, which cannot be solved in a short period of time.

Not yet. No one in the world has ever been on the moon! The Yankees' moon landing was a fake.

The Chang'e Project has.

One, two, three, and four, respectively, belong to the spiral descent, of which the fall is carried out twice! They are Chang'e-3 and Chang'e-4! Landing 3 is Rainbow Bay on the front, and landing 4 is the Von Kármán impact crater in the Kent Basin on the back!

Although it is an unmanned detector, just like a remote control, this has several important implications! There are no problems with deep space measurements, and there are tests to land on the far side of the moon, so the communication of landing on the moon is guaranteed! Chang'e-1 and Chang'e-2, which are self-determined, changed their orbits on Earth to enter the orbit of the Moon, and it is also familiar to enter the orbit of the Moon.

This is the only way to carry out self-determination No. 3 and No. 4, so there is no big problem with the technique or the orbital calculation. From the cycle of lunar orbit to braking to the moon landing, finding the landing support, hovering, and once again verifying the process of soft landing on the lunar surface!

The only technology that has not yet been verified is the return from the lunar surface, but Chang'e-5, which will be implemented by the end of 2019, will validate all technologies for unmanned lunar returns, including the following technologies: lunar surface launch into lunar orbit. Circumlunar orbit docking to transport samples from lunar orbit to lunar orbit, directly through the atmosphere at the second cosmic velocity through the ballistic deceleration back to Earth, or deceleration into Earth orbit and then deceleration into the atmosphere, either side requires considerable technology!

The final assembled mass of the Apollo lunar landing ship was about 45 tons. At the moment, due to technological progress, the total mass of the spacecraft may be reduced by about 10%, but most of this is fuel and supplies, these cannot be removed, so the total mass of the lunar lander may be between 40-50 tons!

Unless the service module and the lunar module command module are merged, the only way to greatly reduce the weight can be achieved, but although there is a requirement that the engine thrust needs to be greatly increased, Chang'e 5 still uses a separate type, so there is reason to believe that the manned lunar landing will also use a classic structure like Apollo! When it comes to landing on the moon, we are most concerned about the load class of the TLI orbit. The improvement is a little more than 4 tons.

Of course, Chang'e-4 is an improved implementation of the Long March 3, and although it has been successful many times, it is clear that the Long March 4 carried out a mission to the moon. Coming back requires a monthly descent level and upgrade as well as a sample mount, so the transportation capacity of about 4-5 tons in the TLI orbit of the Long March 3 is not enough.

The carrying capacity of the Long March 5 TLI orbit is increased to tons, and it is returned to the bilge floor by the orbital module, upgraded to the descent stage, this carrying capacity is still very compact, but it is enough to carry out the Long March 5! Chang'e-5 is much more complex than Chang'e-4, so it can only carry out the task of sampling back from Fat 5! However, for a manned landing on the moon, this is exactly two requirements from unmanned exploration.

Due to the need for adequate space and life support systems for manned spacecraft, the total mass of the lunar landing combination will rise significantly. The total mass of the lunar moving orbit of the Apollo lunar landing ship is about 45 tons. The carrying capacity of the Long March 9 can only approach or exceed that of the Saturn 5.

It's very hard. I think that my country will definitely do it, and my country's current level of scientific and technological strength is very strong, and it is still developing. So I'm sure it's going to happen.

The manned landing on the moon is very technological, and it is also very difficult, and China's scientific and technological strength can do it, because China's scientific and technological strength is very advanced at present.

I think it's very difficult, and my country's science and technology are also developing, so I believe it will be done.

There are few countries in the world that can do this, and our country's current scientific and technological strength can do it.

It is said that the Apollo moon landing in the United States was a lie. China will send a man to the moon in 2024. "In June 2006, Reuters and other foreign countries made a very positive report on the time of China's moon landing, and it is reported that the Western ** report was based on a message from Hong Kong's "Wen Wei Po":

In the "Chang'e-4" project in 2024, Chinese astronauts will likely carry out a mission to the moon. As soon as this news came out, it caused a huge repercussion in China.

According to Xinhua News Agency, interviews with China's chief lunar exploration scientist Ouyang Zhiyuan learned that an unmanned lunar exploration vehicle was launched in 2012, a manned lunar exploration vehicle was launched in 2017, and a lunar space laboratory was established in 2020.

"Chang'e" is going home! When the "Chang'e-5" lander successfully took off from the lunar surface, entered the lunar orbit and successfully docked with the orbital module, we knew that the "Chang'e-5" lunar sample return mission was basically successful! At this time, some people must ask, does the successful sampling of Chang'e-5 indicate that China has mastered the technology of manned lunar landing?

Chang'e-5. Apollo manned lunar landing process.

At present, the United States is the only country in the world to carry out a manned lunar landing in the last century, and the mode process adopted is that the super-heavy rocket (Saturn V) sends the "Apollo" spacecraft to the Earth-Moon transfer orbit, and then the spacecraft ignites the main engine and flies to the lunar orbit. After the lunar module (Eagle), the command module (Columbia) and the service module were separated in orbit, the lunar module landed on the surface of the moon, and after completing its work, it was ignited by the lander's upgrade and left the moon, entered the lunar orbit to dock with the command module, and finally returned to Earth.

Man-made on the moon.

The entire process of the Chang'e-5 lunar sampling mission is actually similar to the Apollo process, which can be said to be a miniature version of the "Apollo" unmanned landing on the moon. From a technical point of view, every process technology of manned lunar landing has been verified in China.

Equipment and technology required for manned landing on the moon.

1. The super-heavy rocket, the Saturn V of the United States had a low-earth orbit carrying capacity of 130 tons, and the Earth-Moon transfer orbit carrying capacity of 48 tons, which could send more than 46 tons of Apollo spacecraft (including command module, lunar module, etc.) on it as a whole. Even at the current level of materials and combinations, the total weight of the lunar landing system is about 40 tons.

The Saturn V giant rocket.

At present, China's largest rocket "Long March 5" has a carrying capacity of about 8 tons in the Earth-Moon transfer orbit, which is far from enough to send people to the moon. To realize China's manned lunar landing program, we must wait for the legendary Long March 9, or use the 921 rocket to launch in stages, rendezvous and docking in orbit and then go to the moon.

Low-Earth orbit rendezvous and then lunar mode.

2. The lunar spacecraft, generally including the command module, the lunar module and the service module, the new generation of spacecraft in China has been successfully tested, and after about 2 years of improvement and optimization, the lunar version of the spacecraft should not be a big problem. But the lunar module, there is no news about this, and its development is not much less difficult than that of a super-heavy launch vehicle.

At present, China has experience in manned spaceflight, but it is in low-earth orbit, and it will take time to develop a life support system to the moon. Although China's "Chang'e-5" ascender was successfully launched from the moon, there is a big gap between its scale and manned.

3. Deep space exploration technology, the success of the "Chang'e-5" mission, means that China's deep space exploration should have no problem in supporting the lunar landing.

4. The second cosmic velocity to return to the earth and travel within the solar system without the gravitational pull of the earth requires the second cosmic velocity (kilometers and seconds), and the speed of returning from the moon into the earth will also be close to this velocity. This item will be verified after the successful return of the "Chang'e-5" return capsule to Earth, which should not be too much of a problem for China. 

Not for the time being, and only the United States has achieved a manned landing on the moon. China's moon landing is Chang'e-5, an unmanned spacecraft. From launch to moon landing, from collecting lunar soil to flying away from the moon, from sample handover to final returner landing on Earth, every step of Chang'e-5 is thrilling.

Now, everyone's hearts that have been hanging for 23 days can finally be put down, and the returner of Chang'e-5 has successfully landed in the scheduled landing area of the Siziwang Banner in Inner Mongolia! The Chang'e-5 mission has been declared a complete success, and the whole process has been perfect. The design of the Chang'e-5 mission is very complex, and if it is only an unmanned lunar sample return, it does not need to be so difficult.

In fact, there is a big consideration behind Chang'e-5, and this mission is entirely designed to simulate a future manned moon landing, in the same way as the Apollo manned moon landing mission of the year.
