Comprehensive Aerospace Command and Control Center in Xinyuehu Courtyard, Anxi Haoyu Technology Headquarters Park.
Wu Hao arrived here early, waiting for the return capsule of the spacecraft to start its return journey. He was not the only one who came early, Zhang Jun, Tong Juan, and Yang Fan all came. Zou Xiaodong went to the battery factory and was not in Anxi.
Not only them, but Lin Wei and other interested people also came to watch.
"Ten minutes to prepare!"
After hearing the report, Zhang Jun couldn't help but complain: "Damn, I feel more nervous than when I launched."
Wu Hao laughed and said: "It's useless to be nervous. The entire return process is completely automatically controlled by the system. Manual command control will not be enabled unless it is an emergency. So, it's useless no matter how much you worry now, just be patient and watch."
Bar."
"I know, but I can't help but feel nervous." Zhang Jun shook his head and stared at the big screen.
Wu Hao shook his head when he heard this, and then looked at Lin Wei. She was staring at the picture on the big screen in trance.
Sensing Wu Hao's gaze, Lin Wei smiled at him, then looked at the external camera footage on the spacecraft on the big screen and exclaimed: "It's so beautiful!"
"Haha, when the technology matures in the future, I will take you up there to play for a few days." Wu Hao said with a smile.
"Go!" Lin Wei rolled her eyes at him, but there was still a longing smile on her face.
"Countdown to five minutes, one minute, thirty seconds, ten seconds, five, four, three, two, one, the return module and the service module are separated!"
I saw the image of the external camera of the spacecraft service module on the big screen, shaking for a moment, the return module detached, and then slowly moved away.
"The return capsule separated successfully and is re-entering the atmosphere along the planned return trajectory."
Bang bang bang bang...
The entire command and control hall burst into warm applause.
"Adjust the service module angle, target, South Pacific Space Cemetery, prepare for re-entry into the atmosphere."
At this point, the service module's mission has been completed. It will adjust the re-entry angle, and then return according to the preset and is about to start its re-entry journey into the atmosphere.
However, it is no better than the return capsule and has no recovery function. Therefore, it will decompose and burn in the atmosphere over the Pacific Ocean. Most of it will be burned clean, and only a very small part will fall into the "space" of the South Pacific.
"Cemetery" area.
The so-called "Space Cemetery" refers to an area located in the Southwest Pacific. This area is called the Pole of Inaccessibility. It refers to the farthest and most difficult-to-reach location from the coastline in any direction on the continent. This difficult-to-reach location
Point, abbreviated as "POI".
Because it is remote enough, very few people are active in this area, so it has naturally become an ideal "space cemetery." There are a large number of spacecrafts that will choose to break down and fall over this area.
Because it is far away from the mainland and there are very few human activities, even if spacecraft debris falls, it will not harm humans. Of course, there is still a certain probability, but the probability of being hit by such spacecraft debris is far away.
It's much lower than your chance of winning the 5 million lottery ticket.
You know, there are basically winners in every draw of the lottery, and until now, no one in the world has been hit by such falling spacecraft debris or even meteorites.
"The return capsule begins to enter the 'black barrier'."
The so-called "black barrier" refers to the fact that the spacecraft's return capsule will generate shock waves when it enters the atmosphere at ultra-high speed, causing the surface of the return capsule and the surrounding gas molecules to be in a viscous and burning state, making it difficult for the temperature to dissipate, forming a temperature of several thousand
High temperature zone of degrees Celsius.
The gas in the high-temperature area and the molecules of the surface material of the return capsule are decomposed and ionized to form a plasma zone. Because plasma can absorb and reflect radio waves, it will attenuate or even interrupt the radio communication between the return capsule and the outside world, so this phenomenon is called
For black barrier.
Therefore, after entering the "black barrier", the command and control center lost contact with the spacecraft's return capsule, and then the spacecraft flew by itself. Only when it flew out of the black barrier area could it re-establish contact with the spacecraft.
Of course, it is not that the return capsule cannot be seen at all. Through photoelectric telemetry equipment and radar detection equipment, the high-speed descending return capsule can be seen.
"The Measurement and Control Center of the Mongolian Space Landing Site reports that the return capsule is being tracked, the telemetry signal is normal, and the flight attitude of the return capsule is normal."
"Attention all units, we will begin to inform you that the first landing site is estimated to be 101 degrees XX minutes XX seconds east longitude and 42 degrees XX minutes XX seconds north latitude."
"Convoy No. 1, 2, and 3, start heading towards the predetermined area." After hearing the announcement, Yu Chengwu, who was sitting in the command and control vehicle, immediately grabbed the radio handphone and gave the order.
"Car crew No. 1 received it!"
"Coach No. 2 received it!"
"Coach No. 3 received it!"
Immediately, a search convoy composed of off-road vehicles began to move from various areas to the predicted landing site. Through the on-board camera, the situation of the convoy can be clearly seen.
"UAV remote control team, how is the situation now?" Yu Chengwu called.
After a while, there was a burst of electricity and a report from the radio: "The drone remote control team reported that twelve large airborne surveillance drones have taken off and are currently flying in good condition. The drones are being debugged.
, the relevant video footage is being transmitted back."
"Okay, you see the picture, keep it up." Yu Chengwu looked at the relevant detection pictures transmitted back by some air patrol drones on the large screen diagonally above, and then nodded and ordered.
"Report, the return capsule has broken through the black barrier and restored communications."
"Attention all units, the second landing site is estimated to be 101 degrees XX minutes XX seconds east longitude and 42 degrees XX minutes XX seconds north latitude."
"Convoy No. 1, 2, and 3 quickly changed direction and rushed toward the estimated landing site."
"The landing site reports that the optical telemetry equipment has discovered the return capsule. The return capsule is in complete shape and the flight attitude is normal."
"good!"
After hearing this report, Yu Chengwu and Guo Yulong couldn't help but roared in a low voice.
Next, we are waiting for this crucial step. Everyone is holding their breath, waiting for this moment to arrive.
"The landing site reported that the return capsule and parachute group have been thrown out and deployed smoothly. The parachute shape is normal and the speed of the return capsule has slowed down."
Bang bang bang bang...
At this moment, everyone could no longer stand still and cheered.
"Attention all units, we will begin to report that the third landing site is estimated to be 101 degrees XX minutes XX seconds east longitude and 42 degrees XX minutes XX seconds north latitude."
"The drone remote control team reported that the return capsule has been discovered!"
In the picture of one of the drones, there was a black spot trembling in the sky above the sky! Then the drone monitoring picture switched to infrared mode, and I saw a bright spot in the middle of the picture, which was descending.
Soon, this bright spot appeared in more drone surveillance images, and it became increasingly clear.
"Attention all units, the fourth landing site will be announced below and is estimated to be 101 degrees XX minutes XX seconds east longitude and 42 degrees XX minutes XX seconds north latitude."
Not long after, a group of convoys arrived at the designated location. Through the observation equipment on the convoy vehicles, the return capsule and parachute group in the sky could be clearly seen.
Yu Chengwu breathed a sigh of relief when he saw this, and then ordered with a smile: "Ask the driver to speed up, and we will go there quickly."
