At 08:52 on June 17, the control hall of Beijing Space Information Transmission Center.
"Pay attention to each number, prepare in 30 minutes!" A clear password from the general dispatcher came from the lobby. At this time, the test participants at each position in the center were closely watching the status of the sub-systems and repeatedly checked the main and standby computer software and satellite control scripts.
"Manned spaceflight is a matter of life. It is very important to grasp spacecraft data anytime and anywhere to obtain the dynamics of astronauts." Zheng Yonghui, the central engineer sitting in the overall post, said that the relay satellite system is a "road to heaven" laid in space. "It is responsible for the important responsibility of real-time communication and transmission between spacecraft, astronauts and the ground.
As the launch time is getting closer and closer, the dispatching passwords in the hall are getting denser, "Five minutes to prepare!" "One minute to prepare!" ... At 09:22, with the "Ignition! Take off" password, I saw the lobby. On the screen, the launch tower is surrounded by rocket tail flames, and the Long March 2 F Yao 12 launch vehicle pierced the silence of the Gobi and flew into the distant space.
"Tianlu No. 1 04 satellite captured Shenzhou! The forward and return links have been established!" Soon after Shenzhou 12 entered orbit, Tianlian No. 1 04 satellite immediately started tracking it. Since then, relay satellites The long-term measurement and control link of the system to Shenzhou 12 is thus established.
"Shenzhou tracking is normal, and forward and return data are sent and received normally!" In the satellite position, engineer Wang Zhen was calm and composed. Before the mission, he led the satellite personnel to draw up a number of plans for the possible emergencies of the satellite. Several emergency drills were organized in a simulation environment.
Soon after the spacecraft entered orbit, the two screens on the right side of the center hall jumped out of the astronauts in the cabin.
In front of the camera, astronauts Nie Haisheng, Liu Boming, and Tang Hongbo waved to everyone with a smile, and the whole hall responded to them with warm applause.
"From Shen7 to Shen12, the relay satellite system has also witnessed the rapid development of my country's manned space technology." Ma Chao, the central commander and dispatcher, looked at the screen and couldn't help but recall the last time he saw astronaut Nie Haisheng on this big screen. scene.
To this day, the relay satellite system is still "escorting" generations of astronauts, but Ma Chao can hardly contain the excitement in his heart every time-"Even if the preparation before the mission is hard, the duty during the mission No matter how tired, as long as you see the picture of the astronauts safe and sound in space, you feel that everything is worth it!"
As time passed, the first change of orbit of Shenzhou 12 began.
"The status of 03 star data distribution and storage software has been set and checked correctly." In the data distribution post, engineer Wang Xue reported calmly.
On the left side of the three-dimensional display screen in the lobby, the real-time simulation screen shows that after several orbit changes, the distance between the Shenzhou XII spacecraft and the space station combination has become shorter and shorter.
"The spacecraft turns 200 meters and keeps it."
"The spaceship turns 19 meters and keeps it."
The thrilling moment is coming, and the atmosphere in the hall becomes more tense.
"01 star tracks Shenzhou and Tianhe as normal, and forward and backward data is sent and received normally!" A clear dispatching voice was sent from the main dispatching post.
"Tianlian-2" 01 is the second-generation relay satellite independently researched and developed by my country. This time it is its first appearance on a manned space mission. In addition to having stronger performance and higher transmission rate, the second-generation relay satellite system It can also achieve multi-objective measurement and control at the same time, and work efficiency is higher.
On the big screen, the crossed bullseye of the Tianhe core cabin became clearer and clearer, and in the field of view of its own camera, Shenzhou 12 was also spreading its wings and slowly approaching.
15 meters, 10 meters, 5 meters...Everyone held their breath.
The Shenzhou 12 spacecraft perfectly overlaps with the core cabin of Tianhe, and the spacecraft successfully meets with Tianhe.
"The docking is normal" and "the docking is locked normally". With the good news from the dispatching broadcast, the hall once again burst into warm applause.
At 18:48, three astronauts successfully stationed in the core module.
"'Tianlu' tracks Tianhe and Shenzhou normally! Forward and backward data transmission and reception are normal!" In the hall, the password of "Normal!" continued to echo.
The rendezvous and docking is over, and the mission of all the scientific and technical personnel of the center is far from over. The three astronauts will accompany them all the time in the sky.
It was evening when I walked out of the mission hall. From early morning to night, there are always people coming and going in the center hall. At the door, a panel printed with the smiley faces of scientific and technological personnel put together "100" looks warm and beautiful. This is everyone "Tianluren" is the best footnote to the solemn commitment to the motherland.
