Chapter 731

The carrying capacity of the rocket is insufficient.

This is just one of the difficulties faced by the manned lunar landing project.

One could even say.

This problem can only be ranked second among all the problems encountered in the manned landing on the moon.

And in first place.

It is the design of a spacecraft to the moon.

As everyone knows.

The lunar spacecraft consists of three parts.

They are the command module, the service module, and the lunar module.

At present, China's largest spacecraft is Tianzhou-1, weighing about 12.9 tons, which is cargo-carrying and functionally similar to the service module, but it is nearly double the 24-ton gap of the lunar landing service module.

Although the quality gap between the two is only doubled, the difficulty coefficient of production and manufacturing is definitely increasing exponentially.

China's manned spacecraft Shenzhou, about 7.8 tons, can return to the earth, which is equivalent to a command module.

Manned spaceflight in low-earth orbit is still under the protection of the Earth's magnetic field, but the journey to the moon is not the same, and the need to face the sun and various cosmic radiations are completely different.

The existing Shenzhou manned spacecraft is definitely not going to work, and it needs to be improved on a large scale.

So.

In order to realize the function of the command module of the lunar spacecraft, the Shenzhou spacecraft must be greatly improved and upgraded.

The lunar module, only the unmanned Chang'e-3, 3.8 tons.

The lunar module is the most important of the three parts of the lunar spacecraft.

But......

Although Huaguo has successfully completed four probes to the moon.

But one thing to be clear.

A probe landing on the moon and a manned landing on the moon are two completely different things.

With one more astronaut in the lunar module, there are more technical problems.

For example.

How to ensure the stable and safe landing of the lunar module on the surface of the moon, so that the astronauts will not be damaged by the huge impact force during landing, and how the astronauts should leave the moon and return to the earth safely after completing the lunar survey mission.

For the current Huaguo.

In this part of the lunar spacecraft, not to mention the most difficult lunar module, even the relatively simple command module and service module cannot be developed and designed in a short time.

On the contrary, it is in the astronaut area.

Because China's astronauts have extremely rich experience in outer space activities, they do not have to worry about not having the right astronauts to complete this manned lunar landing project.

After all.

The quality of Huaguo astronauts is what makes the whole world look at it.

............

One is the carrying capacity of the rocket, and the other is the R&D and design of the lunar spacecraft.

These are the two biggest problems facing the manned lunar landing project at present.

Today, the entire manned lunar landing project is composed of nearly 1,000 research and development personnel.

But three years have passed.

Neither of these two problems has yet to be overcome.

And, at this current pace.

Four years later, in 2025, it is difficult to say that it can be done.

Underground base.

Inside the office.

Wu Zheng finally poured bitter water on Gu Lu.

Wu Zheng picked up the teacup, and with a dry mouth, he drank all the tea in the cup in one gulp, and said with a wry smile, "Gu Lu, brother, I'm really difficult! Seeing that half of the time is about to pass, but the moon landing process is still far away." I sometimes wonder if I should just give up, is it worth such a large amount of money thrown down by the country every year? ”

A manned landing on the moon is not an ordinary money burn.

In the past three years, they have basically burned billions of dollars every year.

And if you want to make the manned lunar landing program officially successful, it cannot be stopped without tens of billions.

But.

Is it worth spending so much money and investing in such a project that you don't know when there will be an actual return?

If we take out this money, we will save many people from the misery of poverty.

Wu Zheng thought about this question more than once.

In the end, he became confused.

Gu Lu turned his head to look at Wu Zheng, who lowered his head with a confused look, and patted Wu Zheng's shoulder heavily.

"Although we set foot on the ground, it does not prevent us from looking up at the starry sky and chasing the sea of stars. Compared to the entire universe, our earth is just a small drop in the ocean, and maybe in 10, 50, or even 100 years, we will not enjoy the actual benefits of the moon landing, but one day, it will prove that what we are doing now is not meaningless. ”

"Do you remember what the astronaut who first landed on the moon said, one small step for man, one giant leap for mankind? As long as human beings exist, human exploration of outer space will never stop. ”

"No matter how difficult it is to land a manned landing on the moon, if it doesn't work in five years, then it will take ten years, ten years will not work, then it will take twenty years, anyway, one day, the footsteps of our Chinese astronauts will definitely set foot in that strange land!"

Gu Lu's words made the confused look on Wu Zheng's face gradually fade, and his eyes slowly became firm.

Wu Zhengyi grinned, "Gu Lu, you're right, that place on the moon, we Chinese must go up!"

"I believe in you!" Gu Lu spoke.

Wu Zheng laughed, "You believe us!"

Gu Lu understood the meaning of Wu Zheng's words, nodded with a smile, and then spoke, "What can I do for you?"

Wu Zheng pondered for a few seconds, touched his chin and thought, "Which part do you want to be responsible for?"

Wu Zheng still planned to ask for some Gu Lu's opinion.

Gu Lu shrugged, "I don't care, you can do it anywhere, you just treat me as a brick, just move it where you need to." ”

Wu Zheng nodded and arranged, "There are rivers staring at the moon landing spacecraft, otherwise, Gu Lu, you can go to the rocket research and development department." ”

Rocket R&D department......

Gu Lumo rubbed his chin and said, "No problem." ”

Although Gu Lu has never had experience in building rockets.

But in terms of theoretical knowledge, Gu Lu is relatively sufficient.

"However, the base for rocket research and development is not here, so I need to trouble you to work again. Wu Zheng said apologetically.

Rocket, that guy is just too big.

The base here obviously can't be put down.

So.

The bases of the two divisions, the Lunar Spacecraft Department and the Rocket R&D Department, are separated.

The R&D department of the lunar spacecraft is based in this underground base.

The rocket research and development department is located at a ground base in Dongchang.

I'm going to leave when I first came here.

Gu Lu didn't have any dissatisfaction.

Again, that's the same sentence.

Everything is in the service of the success of the moon landing.

In front of the state, this small personal loss is completely nothing.

"Unless you rest on our side for another night, I'll have someone send you there tomorrow. Wu Zheng proposed.

Gu Lu waved his hand.

"No, I'd better rush over as soon as possible, and I can get back to work as soon as I go. ”

Seeing that Gu Lu had made up his mind, Wu Zheng didn't say anything.

"Okay, then I'll say hello to the rocket R&D department, but you can just go over as a technical advisor to the headquarters. ”
