Chapter 1094 Non-stop live broadcast in the cabin!
After confirming that the spacecraft successfully entered orbit, Dongfeng Space City’s external public communications were restored.
Nearly a hundred media outlets, which were already ready to go, broadcast the rebroadcast content in text or images in the shortest possible time.
At 12 noon, the news at Station C took the lead in broadcasting the news about "Shenzhou 5 was successfully launched and my country embarked on its first manned space journey."
However, this is just a routine noon news.
As a result, the whole thing is quite restrained, lasting only about three minutes.
The only scenes involved were the rocket ignition, the separation of the booster and the commander-in-chief's announcement that the launch was successful...
It was reported, but not fully reported.
Especially for many people who have been waiting for it for a long time, it is even more exciting.
Like some unscrupulous authors.
I have already told you what plot will be written later, and I have used various means to build up the anticipation.
The result is that the update is very slow, which is very uncomfortable.
Fortunately, C is quite conscientious in this regard.
Although the noon report is not long, it also clearly states that after the news broadcast, there will be a special report on manned spaceflight that lasts about an hour.
It can be regarded as satisfying the requirements of domestic and foreign enthusiasts, as well as some people in the industry...
Of course, it was also a test for the work of Chang Haonan and others...
According to the plan, everything went on without any surprises.
Eleven forty-six noon.
Chang Haonan, who had already completed preparations, picked up the intercom and ordered the Qingluan Satellite Group to formally access and forward the S-band communication signal sent by Shenzhou-5.
In just a few minutes, the image content that had been relayed twice was transmitted back to the Tanzhou ground station in Beijing and the airship working in the stratosphere at an altitude of 35km.
The latter then sent the signal through the third relay to Haojing Ground Station and Dongfeng Space City.
The actual delay of the entire process is about 270 milliseconds.
Soon, the situation inside the spacecraft was once again displayed on the large screen of the launch command and control center.
The picture quality is clear and coherent.
According to the schedule, this will happen to be the astronauts' meal time.
In weightlessness, inconspicuous food residues can cause big trouble.
Therefore it is impossible to put food on plates or similar open containers like on the ground.
Only refer to the design of baby food to ensure maximum safety.
Or just make it all into chunks, so you can eat it in one bite.
So, the first picture displayed on the screen was that the astronaut comrade was squeezing a packaging bag that looked like sucking jelly.
However, it should be filled with pre-made fish-flavored shredded pork or Kung Pao chicken.
For him, this has been the content of countless trainings.
But this was the first time for many of the comrades on the ground to meet.
So, the action of "a macho man sucking jelly" caused a burst of laughter, but unexpectedly made the atmosphere in the measurement and control hall relaxed a lot...
At this time, Shen Junrong turned around He turned his head and glanced at Chang Haonan next to him.
The latter was standing with his hands behind his back, looking at the screen with interest.
In the original timeline, because this period was still in a communication blind spot, the widely circulated scene of the astronauts eating only had a brief clip of swallowing lumpy food.
Obviously not as effective as the hardcore mukbang in front of you.
"Comrade Haonan, Comrade Haonan!"
Chang Haonan called twice in a row before Chang Haonan turned his head.
"Mr. Shen?"
Shen Junrong pointed to the time displayed next to him:
"How did you connect in advance?"
You know, at this time, the spacecraft entered the orbit of the earth. There are about 20 minutes left in the third cycle.
The duration of each Shenzhou 5 lap is about 90 minutes.
In fact, the range that ground measurement and control stations/measurement and control ships can cover is quite limited. Take Kashgar Station and Karachi Station with similar longitudes as examples. Although it is already the westernmost point of China's territory, it is not actually too long earlier than the Dongfeng Measurement and Control Station.
The spacecraft target was not captured until 10:31 on the first lap, which was 9 minutes before the end.
As a result, the second lap was almost 20 minutes ahead of schedule.
It is equivalent to extending the effective communication time to twice that of the past.
This does not include the part that will continue to be effective after leaving the island city measurement and control station.
Obviously there are some differences from the previous plan.
“The plan must be written conservatively, leaving some room for maneuver for ourselves...”
Chang Haonan’s answer highlighted a straightforward answer:
“Maybe Because there are too few service objects connected to the network, the effective acceptance angle of each antenna is larger than originally estimated, which is equivalent to increasing the estimated coverage area.”
"If calculated based on the current situation, by the 8th and 9th Earth orbiting cycle, the effective connection time will be about 50 minutes..."
Faced with this answer, Shen Junrong had no choice but to report With a helpless smile...
In the next few consecutive cycles, there are no special tasks, and the data transmission process is also quite smooth.
Only at 3:54 p.m., when Shenzhou 5 entered the fifth circle and performed its first maneuvering orbit change to simulate avoiding space junk or docking the spacecraft, the signal fluctuated for a moment. .
However, it did not reach the level of interruption, but the delay instantly increased to more than 500ms.
In this way, the time quickly came to 7:30 in the evening.
That is the time when the special program is broadcast.
Considering that the recovery of the spacecraft has not been completed after all, it is impossible to open the champagne in advance for the program content.
It is still in the form of reports and interviews.
However, compared to the noon newsletter, it provides more sufficient content.
There are also two guests to answer some questions raised by the host.
However, at this moment, the image data that can be provided is actually relatively limited.
It's just a few more scenes in the command and control hall, as well as pictures of the astronauts working in the previous few laps of flight.
In order to fill the entire Q&A session, the screen behind the host must play these contents multiple times.
For those who are interested, the focus of this meeting is originally on the content of the interview, and those scenes will not be boring even if you watch them several times.
...
In a private house in Lianhai City.
An old man in his sixties wearing a lieutenant colonel uniform was sitting like an old monk, staring straight at the screen in front of him.
Until the voice of the little grandson next to him reached his ears:
"Grandpa, why do those few paragraphs always play back afterward?"
"Because..."
It was only then that he realized that his vision had been blurred by tears...
The old man's name was Meng Linsen, and on the surface, he was just a retired Air Force pilot. Lianhai Materials Bureau, and later retired ordinary cadres.
But in fact, he was one of the 19 astronauts selected for Project 714 30 years ago.
It can be said that they are the earliest batch of "preparatory astronauts" in China.
However, at that time, the conditions for manned spaceflight were indeed insufficient.
So in 1975, the project was completely cancelled.
Meng Linsen and a dozen of his colleagues were also ordered to return to their original troops, destined to miss the universe in this life.
But today, nearly thirty years after the dream was shattered, I have the opportunity to see Chinese astronauts successfully enter space...
Meng Linsen took a deep breath and adjusted himself Mood:
"Because the spacecraft is rotating outside the earth, it can only communicate with the ground when it passes above us..."
He gestured with his hands while explaining the basics of the spacecraft to his confused grandson. principle.
However, before he could finish his words, he heard the host’s voice coming from the TV:
“Next, we will witness with you that astronauts in space The work and life situation..."
