Movie black technology

Now the Tibetan Antelope is separated from the earth by hundreds of thousands of kilometers. With the bandwidth of the Queqiao relay satellite, it is already a bit difficult to transmit back the equipment parameters and location information on the Tibetan Antelope, so I want to see real-time The picture is impossible.

The videos of the lunar rover and other experiments released in China before were all filmed and then slowly sent back to the earth.

Chen Shen and the other staff in the flight control hall can only understand the current situation of the spacecraft through the monotonous parameters on the screen.

In the blink of an eye, the critical moment of entering orbit has arrived.

"Preparation for orbiting."

In the hall, the master controller informed the audience of the next actions of the aircraft in accordance with the practice of previous space missions.

It's just that the Tibetan Antelope does not require them to perform additional operations, and the autopilot system can automatically complete the orbiting operation.

But even so, everyone still dare not take it lightly.

Next to Shenshen Chen, He Wei had a thick layer of sweat on his forehead, staring at the parameters on the big screen, afraid that if he was distracted, the spaceship would follow in the footsteps of SLS.

Chen Shen was calm and relaxed, turning his head to comfort him from time to time, "Don't be too nervous, no matter how worried you are in this situation, it's useless, so just resign yourself to fate, if something really happens, let's find out the reason, Just build a new spaceship, maybe the first mission of the new spaceship in the future is to salvage the wreckage of the old spaceship..."

I don't know why, after He Wei heard this comfort, he became even more nervous, like an ant on a hot pot: "The more you talk, the more worried I become..."

"..."

Chen Shen swore that what he said was the truth that was in line with objective laws.

But no matter how worried He Wei was, it was useless now.

The communication delay between the moon and the earth is theoretically about three seconds, but if the delay caused by equipment, signal relay processing and other reasons is included, the time will be longer than three seconds.

In other words, when they saw an abnormality in the spaceship, the spaceship had malfunctioned earlier.

Although the spaceship can be operated remotely on the ground, under this kind of delay, if you want to operate the spaceship to save yourself, it is equivalent to playing games with a delay of more than three seconds...

There is no way to win.

Moreover, the operation required for Tibetan antelope in manual mode is much more complicated than that of playing games.

So, if something really goes wrong with the ship, they just lay flat.

The parameters on the screen jump from time to time, linking the heartbeat and breathing rhythm of He Wei and even everyone on the scene. Every time a change occurs, everyone will unconsciously hold their breath, for fear that the parameter will suddenly jump from green to red. Afraid of the alarm going off in the hall.

On the big screen, the parameters and position information of the spacecraft gradually changed, getting closer and closer to the predetermined orbit.

He Wei clasped his fingers tightly, and kept muttering: "It must be fine, it must be fine..."

In the surrounding area, the remote operators who are responsible for the control of various functions of the spacecraft are ready, although their operations will most likely not be able to save the spacecraft...

At the back of the flight control hall, reporters from China Central Television also took their cameras, ready to record the historic moment.

【Successful entry into orbit】

Suddenly, in the middle of the big screen, on a conspicuous empty space, four eye-catching characters were displayed.

The audience immediately cheered, Chen Shen applauded in his place, and He Wei let go of his clasped hands, the palms of which were already covered with sweat.

The reporters behind also sent the good news back to the headquarters as soon as possible.

The edited draft was sent as soon as possible, announcing to the world that the Tibetan Antelope had successfully entered orbit!

After successfully entering orbit, the Tibetan Antelope only needs to run on the orbit, and then decelerate and descend when it passes through the impact point of the Rich Sea.

These operations are not difficult. The most likely problem is that the Tibetan Antelope is not familiar with the gravitational coefficient of the moon, which leads to the wrong thrust output.

However, both Chen Shen and He Wei had considered this issue early on, and it was impossible for this situation to arise.

After successfully entering orbit, the Tibetan Antelope still needs to run smoothly on the orbit for a period of time before reaching the impact site of Chang'e-1.

At this time, the hall became more and more busy. After confirming that the probability of success of the mission was high enough, the CCTV team set up a camera on the spot to reprint the live broadcast of the moon landing.

After the news that the Tibetan Antelope successfully entered orbit was released, the attention of both domestic and foreign countries was immediately focused on China.

This is the only spacecraft other than the lunar rover in recent decades that is about to officially arrive on the moon.

Many people entered the live broadcast room of CCTV for the first time, but now the audience can only see the live broadcast of the host and the flight control hall in the studio, and occasionally a 3D simulation video of the Tibetan antelope landing on the moon.

There is no way, the conditions are difficult, and the live broadcast on the moon needs to wait for the successful erection of laser communication before it can be realized.

The current Tibetan antelope can't even transmit a picture, and the bandwidth of the relay satellite has been fully occupied by the operating parameters.

After waiting for more than an hour, the Tibetan antelope on the track arrived at the predetermined coordinates, and slowed down and landed without any danger.

The moon is 52.36 degrees east longitude and 1.50 degrees south latitude.

This is the location of Chang'e-1, and the big screen shows that the Tibetan Antelope landed next to this coordinate.

It was also from this time that the Tibetan Antelope was switched to semi-manual operation.

Because when it's time to release the experimental load on the spacecraft, the autopilot system can't do this job.

"Prepare to release the laser communication vehicle." The on-site commander commanded into the microphone.

For convenience, the laser communication system is integrated into an unmanned vehicle, so it can also be called a laser communication vehicle.

Across the hall, many people followed a pre-demonstration protocol.

The space inside the Tibetan Antelope is divided into two areas, one is the standby area and the other is the storage area, and the standby area is connected to the rear hatch.

An air pressure door was installed between the two areas to prevent air pressure leakage in the storage area, and the laser communication vehicle that was planned to go down the ground first was placed in the standby area and fixed before going to the sky, and the air pressure door was also closed.

According to the plan, now only the rear hatch of the Tibetan antelope needs to be opened.

The rear hatch will slowly lower to form an inclined ladder.

Then start the laser communication vehicle, control it to go down the inclined ladder, and then start the communication module. After debugging the signal, you can see the real-time picture of the moon in China.

In this process, as long as the staff is responsible for pressing the start button of each link, the unmanned vehicle will automatically execute the corresponding program.

Soon, the parameters displayed on the big screen showed that all scheduled jobs were successfully completed.

Although there is no real-time picture, on the moon 380,000 kilometers away, the laser communication vehicle has already touched the soil of the moon through an inclined ladder.
