Chinanews.com, Beijing, October 16th, title: "Tianlian" satellite on Shenzhou Xuntian Road to help "Shen XIII" launch and rendezvous and docking
Author Zhang Mengmei Wang Ran Ma Shuaisha
Just after midnight on October 16th, thousands of people had already fallen asleep, and there was silence in Beijing Aerospace City.
In the cold autumn night, the lights in the task hall of the Beijing Space Information Transmission Center appeared warm and bright. The center's scientific and technical personnel shuttled between the posts, checking the status of various equipment in an intense and orderly manner.
Soon, they will usher in another historic moment - the Shenzhou 13 manned spacecraft carrying three astronauts will be launched from the Jiuquan Satellite Launch Center.
Zheng Yonghui, the central engineer sitting in the overall position, said that as an important measurement and control method for the construction of China's manned space station, the relay satellite system has continued to provide data services for thousands of times for the Chinese space station complex, which has successfully guaranteed rendezvous and docking, The smooth implementation of various key events such as world calls and cabin exit activities.
This mission will continue to call Tianlian-2 01, Tianlian-1 03, 04 to provide 24-hour uninterrupted monitoring and control services for the combination of Shenzhou 13 and Tianhe core capsule, Tianzhou II, and Tianzhou III. .
Behind the reliable and stable "information sky road" is the unremitting struggle of the vast number of scientific and technological personnel in the center.
"Tense and orderly work rhythm is the normal state of space station missions." Zhang Yongxiu, an engineer on the ground station, pointed to a thick stack of materials and said that before each mission, the center will organize multiple system-wide and full-process comprehensive exercises. , Covering multiple aspects such as process, emergency response, coordination, command, etc., each time has a different focus, this time, they have drawn up a detailed and comprehensive plan manual for various emergency situations.
"Attention, 15 minutes to prepare!" A clear password was uploaded from the command and dispatch post.
Entering the final state inspection stage, everyone's expressions are serious and serious.
"Before this mission, in addition to checking and confirming the technical status change points and configuration changes, we also carried out inferences about the implementation of the problem to zero, the special maintenance of the ground terminal station, and the seasonal maintenance of the computer communication system. State review, everything is presented in the task in the best state." Ma Chao, the central commander and dispatcher, said.
The launch time is getting closer and closer, and the dispatching passwords in the hall are getting denser, "5 minutes to prepare!" "1 minute to prepare!"...the countdown sound bursts, and the tension in the hall is getting stronger and stronger, the rocket on the screen Waiting in the dark, even more majestic.
At 0:23, with the "ignition" command, a huge roar that shakes the sky and the earth resounded across the Gobi, and the dazzling flames cut through the tranquility of the night. The Long March 2 Yao 13 carrier rocket lifted Shenzhou 13 The manned spacecraft soared into the sky, leaving a dazzling light in the vast night sky.
"Tianlian-1 04 star captured the spacecraft! The forward and return links have been established!" Soon after the ship's arrows separated, Tianlian-1 04 star immediately captured the Shenzhou 13 spacecraft.
"Because the astronauts were on a business trip for 6 months, the scientific and reasonable deployment of relay satellite resources has brought greater challenges when other missions are in parallel, but we are confident that we will be able to deliver it. Satisfied with the answer." In the overall position of the satellite, engineer Zhao Bin was calm and composed.
"Tianlian No. 1 04 satellite tracks normally, and forward and return data are sent and received normally!" After a while, Shenzhou 13 entered orbit smoothly and entered the autonomous fast rendezvous and docking mode.
"Thanks to the advantages of the wide coverage of the relay satellite system, we can monitor and control the Shenzhou 13 manned spacecraft while continuing to track the space station assembly." Zheng Yonghui pointed to the hall screen and saw Zhai Zhigang and Wang Yaping on one side. The real-time dynamics of the three astronauts, Ye Guangfu, and on the other side are the in-cabin images of the Tianhe core module and the Tianzhou-3 combination. The middle simulation image shows that the astronauts are moving away from their "space homes". The closer it is.
"The spacecraft turns 19 meters in the radial direction and approaches."
"The spacecraft enters the holding point."
At 6:56, the image of the Tianhe core cabin outboard camera sent back by the "Tianlian" satellite clearly showed that the target of Shenzhou 13 was approaching precisely and bit by bit.
"The docking and locking is complete!" The command and dispatch sound came from the scene.
Warm applause roared in the hall, and the relay satellite system once again successfully guaranteed the autonomous rendezvous and docking of the Shenzhou spacecraft!
"The end of the rendezvous and docking is only the beginning of our mission. In the next six months, we will continue to work hard, accurately measure and control, and provide reliable and stable data transmission support for the various tasks of the Shenzhou 13 mission!" In the middle, Ji Tao, deputy chief engineer of the center, said firmly.
It was early morning when I walked out of the hall, and the task building centered on the sun was plated with a golden coat.
After struggling all night, there was no tired figure in this building. There were smiles on everyone's faces, expressing the joy of success to each other.
They firmly believe that in this harvest season, "Tianlu Ren" will continue to reap one victory after another.
