Chapter 417: Before Departure (Page 1/1)

On the evening of November 30, it was the last night before the official launch of the Chang'e lunar landing project.

Li Hao accompanied Director Qiu Shi to the space shuttle airports owned by the Space Exploration Group.

Niu Zhengfeng is leading the moon landing team to carry out the final maintenance work of all the systems in the airport.

They were accompanied by CCTV reporters, who carried cameras and were led by airport staff to choose to film about the space shuttle and the airport.

The interview team from CCTV did not prepare for live broadcasting, but adopted the method of recording and broadcasting.

If the Chang'e moon landing project is successful, they will edit and publish the images to boost the confidence of the people.

If the Chang'e lunar mission fails, these images will help analyze the reasons for the failure. It can only be kept in a small cabinet in a certain confidential archive. Waiting for later decryption.

The interview team was collecting materials, and Li Hao and Qiu Shi went directly to the second command room of the Chang'e moon landing project at the airport.

The airport is mainly responsible for the take-off and landing of the space shuttle, and the distribution and transmission of communication keys.

The Yanjing Aerospace Command Center is managed by Deputy Commander-in-Chief Lin Zhipeng. They mainly play a coordinating role.

The reason why it is the first command room is that it also undertakes some display functions for reporters to interview, leaders to inspect, and foreign guests to visit.

Li Hao saw that Niu Zhengfeng in the command room was methodically inspecting every detail of the lunar landing project.

Li Hao took the opportunity to ask in his free time: "Niu Gong, how are we preparing for the communication between the earth and the moon." ”

After Niu Zhengfeng heard this, he saw that I was accompanying Li Hao and Director Qiu Shi, so he summed it up in plain language: "We chose to land in Hongwan District because it is on the front side of the moon. In the evening hour, we can have a direct connection with the Moon through the Earth.

It doesn't matter if the moon goes to the far side of the Earth, we have five satellites deployed in geosynchronous orbit around the Earth. Three satellites were deployed in geosynchronous lunar orbit.

They form a complete communication network between the Earth and the Moon, which is enough to ensure efficient data transmission between the Earth and the Moon. ”

When Qiu Shi heard this, he asked Niu Zhengfeng: "I heard that in this Chang'e moon landing project, the astronauts almost did not make any movements during the flight phase of the space shuttle.

The Space Shuttle is an entire Earth Command Center. If it is due to the time-lapse effect of electromagnetic waves.

In the event of an emergency, there should be a delay in the instructions transmitted by the ground command center, resulting in a slow response from the shuttle.

Why not give the astronauts more authority to deal with the dangers encountered on the shuttle? ”

The average distance between the Earth and the Moon is 380,000 kilometers, which is very close when measured in light years by cosmic objects.

But for the existing technology of mankind, the distance between the Earth and the Moon is still very long.

Even at the highest speed of light known to science, it will take 1.3 seconds to travel from the Earth to the Moon.

Light is a type of electromagnetic wave, and it takes 1.3 seconds for the electromagnetic waves used for communication to travel between the Earth and the Moon. Round-trip confirmation command, which takes 2.6 seconds.

That's not a long time in normal times. But in the case of an emergency for the Space Shuttle, the time of 2.6 seconds will have a fatal effect.

When Niu Zhengfeng heard Director Qiu Shi's question, he looked at Li Hao and stopped talking.

"Niu Gong, tell Director Qiu about our solution to this problem.

This method does not need to be kept secret, and the country's progress in the field of quantum science is much higher than ours. Li Hao saw Niu Zhengfeng's performance, and he immediately commanded.

The company solves the problem of electromagnetic communication delays, uncontrollable. It is to use quantum communication, which is now the only discovery in the scientific community that can transmit information instantaneously.

The research of quantum technology in the physics laboratory has always been in a very shallow state.

They had it not been for a special steady-state particle found in meteorites. Nor can it be transmitted to such a distance with quantum communication.

Liu Hong, who is in charge of quantum communication, although he has obtained a super brain. But the superbrain only gives the brain a great boost in information processing.

For scientists' creativity, the improvement is limited.

Liu Hong is a doctoral student of Academician Pan Jianwei, the father of quantum science in the world.

Academician Pan has a large number of doctoral students, and outstanding doctoral students have already been recruited by the state. Left to them to recruit outside companies, it is definitely not a high-level talent.

After Niu Zhengfeng heard Li Hao's command, he explained to Qiu Shi: "Director Qiu, our company uses quantum communication, which can instantly hit the moon from the earth.

Due to the small amount of information transferred, we have multiple scenarios built-in. It is up to artificial intelligence to make judgments on a case-by-case basis.

What Command on Earth can control is to turn on certain permissions of the artificial intelligence and allow him to act according to the established plan. ”

"Your quantum communication can be transmitted stably between the earth and the moon, I didn't expect to make such a big result silently." Qiu Shi sighed.

He was about to continue his questioning when he heard an employee enter the command room.

Said respectfully to them: "Mr. Li, Mr. Niu." The astronauts are ready, officially into a state of readiness, do you want to see them? ”

Li Hao took the initiative to invite Qiu Shi and said, "Director Qiu, let's go see the astronauts." ”

"Well, they are all national heroes, and they should be encouraged." Qiu Shi nodded in agreement.

Li Hao and Qiu Shi quickly walked to the room where the astronauts were, and he saw that the CCTV interview team was filming.

The five astronauts, Gao Gao, Gu Yu, Chu Xiu, Lin Ziheng, and Lan Lian, wore light blue spacesuits.

Now Lan Lian is reading a letter, the content of the letter is very simple, and it is also very touching.

After listening to this, Director Qiu Shi said with emotion: "I didn't expect them to be reading a suicide note. ”

Li Hao said helplessly: "This is also a matter of no choice, although we have done a lot of safety measures for the space shuttle."

But there are many unpredictable risks in the universe, and no one can guarantee that every trip is 100% safe. ”

Director Qiu Shi saw that after they read the suicide note, some of them still had tears on their faces.

He walked up to the astronauts and encouraged them: "You are the pride of the country and will land on the moon as the first batch of astronauts in China."

You will be the prelude to the development of the Moon, and we are all very proud of you.

I won't say anything else, you must come back safely. ”

After a brief meeting with the astronauts, the astronauts walked to the nitrox chamber.

They all need to sleep in a hyperbaric chamber for the rest of the night. After the cells are strengthened with the booster solution, they are already able to store more oxygen in their bodies.

They usually live on the earth and can be replenished with oxygen at any time. Now, in order to cope with space activities, it is necessary to actively oxygenate their bodies.

The astronauts added oxygen, which means that the Chang'e lunar landing project has officially entered the countdown.
