For the two NASA astronauts trapped in the Aitken Basin at the south pole of the moon, their situation has become increasingly dangerous as the reserves of oxygen and other resources in the Artemis lunar module continue to decline.

As a 'space power', the United States naturally cannot watch its astronauts being 'trapped' on the moon like this. NASA and White House have held multiple meetings in succession to discuss ways to rescue their own astronauts.

Currently, there are two options before NASA and White House.

The first one is to launch the BRF rocket and lunar exploration spacecraft to the moon again, and send new astronauts to rescue the two people trapped in the Artemis lunar module.

But this method is too difficult.

First of all, landing on the moon is a huge undertaking, especially manned landing on the moon, which is extremely demanding in terms of orbit calculation and preparation.

Of course, if this is just the case, there is still a slight possibility.

After all, Space-X has a reserve of BRF heavy-lift rockets and can complete launch activities again.

But the key point is that the oxygen and supplies on the Artemis lunar module may not last until their rescue comes.

Because of the deployment of a lunar surface base, the oxygen supplies carried by the Artemis lunar module for this moon landing were not as sufficient as those of Apollo 11. Part of their oxygen and supply reserves were placed on the life

in the maintenance unit.

For astronauts who land on the moon, as long as they can turn on the life support unit, they can get enough oxygen and supplies, which is more than enough for them to last on the moon for a month.

But no one expected that they would not even be able to get out of the lunar module.

This makes it seem unrealistic to relaunch the BRF heavy-lift rocket for rescue operations.

The second solution is to have the Artemis lunar module ignite and lift off, return to the Orion multi-purpose manned spacecraft, and try to see if it can open the moon landing with the help of another astronaut.

cabin.

However, this method still carries great risks.

Because judging from the inspection data returned by the two astronauts currently trapped on the lunar module, this landing error not only damaged the landing gear, but its chain reaction is very likely to damage the entire lunar module.

side of the engine.

This means that the Artemis lunar module is very likely to be unable to complete its normal flight and orbit. Once any deviation occurs, the death of the two astronauts will be waiting for them.

Faced with this situation, neither NASA nor White House dared to easily allow the lunar module to return to lunar orbit and dock with the Orion multi-purpose manned spacecraft.

So much so that judging from the current situation, no matter which plan it is, it seems unrealistic.

.......

While NASA is worryingly discussing how to rescue its own astronauts, on the other side is the moon, 380,000 kilometers away.

After setting foot on the lunar surface, the two Chinese astronauts cooperated with each other and began the lunar exploration work.

Facing the Lan Yue lunar lander, Chen Dong took off the equipment carried from the lunar module and deployed it in a calm and orderly manner.

Beside him, Liu Yang took pictures of the overall situation of the Lunar Landing Module through the filming device on his spacesuit, and transmitted the data back to Earth for engineers and technicians at the space center to monitor the landing of the Lunar Module.

Make a judgment on the subsequent situation.

These are the first steps that need to be carried out after landing on the moon. Whether it is the ground control center or the astronauts who landed on the moon, the most important thing is to ensure that they can return from the moon smoothly.

And when all the preliminary preparations were completed, a waving red flag appeared in front of the camera.

Standing on the moon, Chen Dong and Liu Yang held hands with bright flags, faced the camera and gave a slow military salute, and then inserted the red flags in their hands into the lunar soil.

Looking at the waving red flag on the moon, at this moment, both the staff of the space center and the audience squatting in front of TVs, computers and mobile phones were filled with tears of excitement.

【China is awesome! Crazy shouting.JPG!】

[The red flag flutters in the wind! The bright moon illuminates the heart!]

[The Shenzhou flies to the sky, Chang'e explores the moon, and the sea of ​​stars embraces the moon. Our journey is the sea of ​​stars!]

[Warm congratulations on the successful manned landing on the moon by Xinghai! Bravely reach the peak of science, we are on the way!]

[Chang'e, where is Chang'e? Chang'e is coming out to pick up the guests soon!]

【I am looking up, above the moon~】

【?Why can you make voice calls upstairs? 】

[I don’t know how many times I’ve read it, but a loser like me is very moved when watching national events. (dog head.jpg)]

Seeing the bright red flag standing on the moon, hundreds of millions of viewers in the live broadcast room were so excited that they couldn't help themselves

The red flag planted in the lunar soil not only represents the strength of the country, but also the belief that supports the development of communism!

They successfully allowed astronauts to set foot on the moon, successfully took over the flag from the big brother of the last century, embarked on a new path, and went further and better!

Just as the barrage said, the mission of inheritance continues, and their goal is the stars and the sea!

...

In Xia Shu Space Base.

When the five-star red flag was planted on the surface of the moon and stretched out, everyone stood up excitedly, and thunderous applause resounded throughout the entire command center like waves.

After half a century of pursuit, we finally surpassed it today.

Looking at the images transmitted back by the shooting device, Xu Chuan had a happy smile on his face.

After more than a year of busy work, the manned moon landing, an epic project for China, was finally completed in his hands.

Looking at the red flag unfurling without the wind, he took a deep breath and exhaled it for a long time, and his heart that had been hanging around finally relaxed a lot.

The work of landing on the moon is completed, and the most important point has passed.

In the next forty-eight hours, Chen Dong and Liu Yang will unfold some basic supplies and equipment carried on the "Lanyue" lunar lander.

This chapter is not finished yet, please click on the next page to continue reading the exciting content! Such as passive seismometer, laser ranging reflector, lunar mineral spectrum analyzer, lunar soil structure detector, etc.

They will use these equipment to conduct a detailed inspection of the lunar surface they landed on, and use drilling equipment to collect some lunar soil and lunar rocks.

In the future, Xinghai, which is sailing in lunar orbit, will replenish life support units and some materials for building lunar bases on the lunar surface during periodic orbits around the moon.

In some ways, the symbolic significance of the first manned moon landing is greater than the actual scientific research work. But they will not waste this opportunity to make more preparations for subsequent lunar development.

Through the powerful carrying capacity of the Xinghai, the Xinghai Research Institute carried part of the materials for the construction of the lunar base.

For example, life support units, intelligent unmanned equipment, 'dry-mixed autoclaved lunar soil bricks' preparation equipment that tests whether lunar soil can condense into blocks, etc.

Some of the names of these equipment and equipment sound quite "funny", but they are all the crystallization of wisdom of various scientific research institutions, and they are all being prepared for the subsequent construction of China's lunar surface base.

You know, building a lunar base on the moon, especially a large lunar scientific research base, such as the lunar surface biosphere that Xu Chuan had talked about with Academician Wu Weihua of Huanong University before.

These construction projects will consume a large amount of construction materials, and due to the limitations of the spacecraft's carrying capacity in the short term, the cost of indirectly transporting materials from the earth to the moon will be extremely high.

Therefore, it will be an effective method to directly collect and utilize lunar soil from the lunar surface for in-situ construction using local materials. This is also the current mainstream view in research on lunar surface construction materials.

Lunar soil itself is also an in-situ construction material with important processing value.

It is not just China that has this idea. As early as the last century, after the United States manned spacecraft, NASA's Jet Propulsion Laboratory conducted corresponding experiments.

Experiments have shown that 'using lunar soil as a protective layer for lunar buildings can greatly reduce material performance damage and aging caused by cyclic stress and radiation caused by the temperature difference between day and night on the building structure.'

This also means that it is not impossible to collect materials from the lunar surface and complete the construction of a lunar surface base.

It's just that the extreme environment of the lunar surface, such as ultra-vacuum, low gravity, large temperature differences, lack of water resources, etc., has a great impact on the heat conduction, pressurization and other processes during the preparation of construction materials (such as sintering bricks).

And ensuring the life safety of astronauts is also an important task of lunar construction.

Its internal environment control technologies, such as air supply pressure regulation, gas composition control, temperature and humidity control, ventilation and purification, fire prevention and control, water management, waste management, etc., are also difficult to solve.

How to overcome and solve these difficulties is something that China needs to seriously ``````````````````

Of course, these are all issues that need to be considered in subsequent aerospace development. The core and key at present is still the perfect completion of the first manned moon landing.

After all, only when the astronauts are completely sent up and brought back successfully can it be considered a successful manned moon landing.

.......

In the main control room, Xu Chuan also breathed a sigh of relief after the two astronauts Chen Dong and Liu Yang successfully launched activities on the lunar surface.

The current progress is quite smooth. At least in the next forty-eight hours, both he and other employees in the space base will be able to take turns and take a short rest.

At this moment, Director Wu Yuankang from the National Space Administration in the control room walked in quickly and reported: "Academician Xu, there may be some unexpected situations in the Artemis lunar landing module at NASA."

"Accident?"

Xu Chuan looked over in surprise.

The last news I received from Wu Yuankang was that NASA stated that the Artemis lunar module had successfully separated from the Orion multi-purpose manned spacecraft and successfully landed on the moon.

When he received the news, he sighed with regret and hurriedly hurriedly, but this time the moon landing was preempted by NASA.

But at that time, he was presiding over his own manned moon landing activities, and he didn't have much time or energy to pay attention to the progress of NASA. After regretting it for a while, he didn't care too much.

Wu Yuankang nodded and replied: "The latest information received is that NASA's Artemis lunar module had an accident when it landed, causing damage to the lunar module and the door could not be opened normally, and the astronauts were trapped.

Inside the lunar module."

"ah?"

Upon hearing the news, Xu Chuan opened his mouth and was stunned for a moment.

He glanced at Wu Yuankang in disbelief and asked in surprise: "The lunar module is damaged? The astronauts are trapped? What's going on?"

Wu Yuankang: "The specific reason is not yet clear. The space agency has issued an order, notifying the Chang'e-5 orbiter currently in orbit to use the remaining fuel to make an orbit change and go to the Antarctic Aitken Basin to check the situation.
