The talented people in Jiangshan have put together a variety show

After showing respect, of course both parties are in a good mood and extremely happy.

Qiu Feng even gave the space station made of flour dough to the engineer.

The engineer also said: "Actually, I think it might be more interesting to split it into more detailed models that are more realistic. But the threshold is too high. Children may not be able to adapt to this type of toy."

He Jun and Qiu Feng also felt the same way.

After the space station learned about it, it went back to grow lettuce again.

He Jun and Qiu Feng were planting lettuce well at first, but they never expected to receive the last mission from the program team to participate in the live broadcast in space.When the program team handed over the task card to He Jun and Qiu Feng, let alone the audience, He Jun and Qiu Feng were also stunned.

Of course, it is impossible for Vacation and the program group to participate in the live broadcast of the docking with the space station alone.

Today, the usual time for astronauts to stay on the space station is six months.They have a lot of work to do in these six months, and live broadcasting to the public is one of their experiments.

Someone in the barrage counted the time and reacted: "Wait, I remember that in winter, there was indeed a live broadcast in space. It was astronauts giving space lectures to students."

"I remember it too! There are tens of millions of students participating, and they all have to watch it."

"I'm a teacher! Our school also watched the live broadcast! But the interaction is not our school. Our interaction is in the Science and Technology Museum."

"Did there be a vacation at the time? I didn't notice it at all. Wasn't the co-host at that time an official host? One of the explainers on the ground was from the aerospace industry, and the other was from the school."

The audience looked shocked and puzzled. In the camera, He Jun lowered his voice and asked the program crew: "Are you sure? We want to cooperate with the live broadcast? Is this our variety show that can be broadcast?"

After he finished speaking, he realized that he didn't mean whether he could broadcast or not.He re-explained: "I mean, this live broadcast is definitely something we can participate in? This must be a more official program? We don't seem to be qualified."

How can they join in a mere variety show?

Qiu Feng took the task to look over and over again: "Did we serve tea and water to the busy people in the live broadcast in the past?"

Director Hong's voice came from the program group: "We are participating in the content before the live broadcast."

How to get involved?He Jun and Qiu Feng went to the spaceflight control center with nervous and excited emotions.

Due to the live broadcast, many cameras have been set up in the spaceflight control center at this moment.These cameras are all official TV cameras.And on the seat at the moment, there are staff members sitting on each control seat in rows.

The official host and staff have already started to control the equipment, and there are also people sitting in many positions behind the command seat of the console.

Now because the aerospace staff have jobs, there is no way to bring He Jun and Qiu Feng's program team to explain, so another host communicates with He Jun instead.

At this moment, the host's work has not yet started.He didn't have any drafts either, and facing the camera, he chatted with He Jun Qiu Feng who was meeting him for the first time: "Hello everyone, Hello He Jun Qiu Feng. I am the person in charge of teaching this space live broadcast and the host in the control center. "

He Jun responded to his greeting.

The tone of the official host is different from the tone of the variety show hosted by He Jun.The former is clearly pronounced, and the tone of speech is similar to that of the news, while He Jun's speech is to mobilize the atmosphere of the show, from gentle to gentle, and sometimes requires appropriate exaggeration.

"In this live broadcast, in fact, it can be seen from the camera that our astronauts have already started the link debugging of the equipment with the ground control center. They will use mobile camera equipment and Bluetooth headsets to communicate with our schools in many regions. live lectures."

With another host field controller, He Jun listened and cooperated: "Mobile camera equipment and Bluetooth headsets, that means we can also have network connections and Bluetooth connections in space, right?"

Moderator: "Of course. In space, our astronauts can have the Internet and use Bluetooth devices. They can send us messages at ordinary times, and they can celebrate with us during the Chinese New Year. The staff of our monitoring and control station on the ground With close cooperation, in the process of communicating with each other, we can grasp the situation of the astronauts in space as quickly as possible."

He Jun and Qiu Feng applauded.

The host has never participated in a variety show, so he found it very interesting and funny that He Jun and Qiu Feng cooperated so well.Because the occasion is more formal, he can't be too playful.

By the way, he helped to introduce the situation in space: "Our astronauts actually seem to have no gravity in space, and it is very relaxed. In fact, it is equivalent to that they have to control their bodies in microgravity. When controlling the body without chaos After floating, they have to pick up the camera and interact with us live on the ground. This actually requires a high level of physical fitness."

He Jun can understand.

He and Qiu Feng participated in the weightlessness simulation.Know how difficult it is to control yourself in a weightless environment, let alone hold the equipment in this environment and have to stabilize the equipment for another job.

Just maintaining balance takes a lot of energy.

The movement of turning around on the ground is extremely simple, but it is difficult enough to turn around in space.When the upper limbs turn, the lower limbs will turn in the opposite direction instead, and you have to "find a way" to turn together.

This kind of difficulty is almost difficult to show in the lens. Only when the reality participates in the weightless environment can it be clearly perceived.

The camera turned to the large screen in the control center at this moment.The three astronauts can be seen on the big screen looking relatively relaxed and busy.They had to set up the scene, and as the host just said, they had to conduct a link test with the ground.

The so-called live broadcast will definitely have a certain delay.But for modern technology, the current live broadcast delay has reached a very small level, which is even difficult for viewers to detect.

For astronauts, they have to be lecturers and photographers at the same time, which is actually very busy.

Because there are three astronauts, the three astronauts are assigned jobs.One is in charge of giving the lecture, the other is in charge of following up with the camera, and the third is in charge of contacting the ground console to observe the shot and ensure the smooth progress of the whole live broadcast.The fixed lens is placed there, and the three astronauts are photographed.

Of course, the lecturers in the middle will change, and the shooting work will also be handed over.

In the ground control center, the staff contacted the astronauts [-] kilometers away.The astronauts also took the computer with them.When there is a slight movement, it floats around, and the movement is much slower than on the ground.

He Jun noticed that there was indeed a slight pause in receiving information from the ground in space.But this pause is like a person making a phone call. It only belongs to the kind of pause of "listening to the other party", and it can indeed be regarded as negligible.

Everyone was busy, and He Jun and Qiu Feng didn't even need to come over to bring tea and water.Like the host next to them, they can only give pre-science guidance without disturbing the staff as much as possible.

Qiu Feng was curious about today's live lecture.He asked the host: "What is the content of our live lecture today?"

The host briefly talked about the process: "Today our astronauts have a lot of live lectures. One is to lead the students to understand and visit the real space station, and the other is that many students have some questions about space, and our astronauts have to carry out corresponding training. To solve the confusion, the third is that the astronauts explain the various tasks they need to perform in space every day."

He Jun and Qiu Feng made the space station, and the audience knew more about the space station than they actually did.He Jun knows that the space station has an experimental cabin, so in addition to maintaining daily life and working outside the cabin, astronauts also have special experimental tasks in space.

He specifically mentioned: "I know they have to exercise, do experiments, and have extravehicular activities."

The host responded: "Yes. Their daily life is very rich." They have to say hello to the earth during the holidays, and they are very busy.Ordinary people think that they must be bored. In fact, after working and interacting more, the boredom will be much less, and the psychological state will be much better.

"This live broadcast is of great help to students in understanding the aerospace industry. I also hope that in the days to come, more outstanding young people will be able to join the aerospace industry."

The host said one set of words after another, which made He Jun very touched.

Especially when he found that the host was also paying attention to the aerospace work when he was speaking to the camera, and would bring up the topic from time to time, as if it had been rehearsed countless times, he was even more impressed.

He Jun and Qiu Feng received the notice of the pre-science popularization of this live broadcast in person, without any preparation at all, and did not know the specific content.

But that's it, the two of them and the host can fully cooperate, they are responsible for asking questions, and the host is responsible for answering.

He Jun asked: "It should be live broadcasting soon, what is everyone preparing for now?"

Host: "In space, the astronauts not only need to contact the ground just now to ensure the smooth flow of live broadcast information, but also ensure that the teaching aids are not damaged."

Qiu Feng asked the host: "Is it something sent up by a cargo spacecraft?"

The host affirmed: "Yes, some of them were sent into space by cargo spacecraft, and some of them were brought into space, which is one of their experimental tools. Because they will experience a relatively harsh environment during the flight, it is necessary to test the performance. The ____ does not work."

Astronauts have a lot of work, and so do those who work on the ground.

Some staff are responsible for communicating with astronauts, some are responsible for communicating with other personnel in the measurement and control station, and some are also communicating with people who set up interactive teaching classes in various places.

After all, there is interaction in the live broadcast, and the students have to start classes simultaneously.

At this point, He Jun couldn't help feeling: "Every job has to be controlled, and it's not easy for everyone." This live broadcast really not only demonstrated the technology, but also broadened the students' horizons.

After all, the host is in a variety show, so he made a joke: "Every time I see that current students have this kind of welfare treatment, I hope that I will immediately shrink my age by 20 years and become a student again."

He Jun joked: "From then on, establish the ambition of spaceflight, and become a successful astronaut in the future."

The host gave a thumbs up: "That's right, that's right."

The joke is over, the live broadcast is finally adjusted to the right situation, and it is time to prepare to start.
