Spring is blooming, and business is booming in Beijing Aerospace City. After a few months, the Dongfeng Landing Site of the Jiuquan Satellite Launch Center welcomed the astronauts home again.
"Attention to each number, I am Beijing, and I will call each number below..."At 8:08 on April 16, Beijing issued a return search and rescue mission. The road closure and control team, the joint search and rescue team, the search and rescue recovery support team, and the search and rescue reserve team arrived at the standby position one after another, ready to welcome the spacecraft home.
On the screen in the lobby of the Beijing Aerospace Flight Control Center, you can see that the three astronauts in the spacecraft are in full force. They sometimes adjust their posture and sometimes confirm their technical status with the ground.
"The engine is turned on, and the return brake begins." With a dazzling light flashing on the big screen, the speed of the spacecraft gradually slowed down, which means that the return capsule carrying the three astronauts is about to return to the earth home.
"Beijing, the eagle reports, the air team took off and headed to the standby airspace, and the report is over." The reporter saw from the big screen that the army green helicopters soared like eagles, complementing the khaki Gobi.
The 6 months of "space travel" set a new record for Chinese astronauts in orbit, and also brought new challenges to the relay satellite system.
"In the face of the fact that space-based measurement and control and data relay tasks are becoming more and more intensive and the guarantee time is getting longer and longer, we are constantly looking for ways to improve our capabilities." Zheng Yonghui, an engineer in the General Office of the Beijing Space Information Transmission Center, told reporters that in the past six months In the center, all the scientific and technical personnel of the center have continuously witnessed the Shenzhou 13 crew to refresh China's height in space. While successfully completing the mission, they also deeply felt the glory and pride of joining the motherland's aerospace industry.
"The propellant compartment is separated!" "The spacecraft has entered the atmosphere!" The Beijing Aerospace Flight Control Center issued a return command through the ground measurement and control station, and the voice of the command touched the hearts of everyone on the scene.
Immediately afterwards, the return capsule entered the black barrier area. In this area, the plasma layer generated by the intense friction between the surface of the capsule and the atmosphere formed an electromagnetic barrier, and the communication between the sky and the earth was temporarily interrupted. In just a few minutes, everyone in the hall stared at the screen with bated breath.
"There is a black barrier in the return cabin." The camera switched to the vast Dongfeng landing site, and there was pleasant news from the walkie-talkie. The spacecraft is running along the predetermined track towards the landing site.
"Returning is really exciting!" Zhai Zhigang's calm tone came from the signal, which caused laughter in the flight control hall.
On the vast Gobi Desert, the main parachute was opened, the heat-proof outsole was thrown in the return cabin, and the five helicopters began to fly together. The ground team and the mobile search and rescue team went out to search. Eagles flew high, warriors galloped, and the Dongfeng landing site played a search and rescue symphony of cooperation between heaven and earth.
"Bang!" At 9:56, with a loud noise, the capsule landed safely and finally returned to the embrace of the earth. At the same time, the establishment of a warning area, the erection of portable stations, and the detection of anhydrous hydrazine in the cabin were carried out in an orderly manner.
"I'm about to open the cabin door, you all pay attention to safety." The 27-year-old Su Liming is the cabin operator of the Shenzhou 13 search and recovery mission, and his young face is full of calm and confidence. "Welcome home!" After balancing the air pressure inside and outside the cabin, Su Liming slowly opened the cabin door, and the Shenzhou 13 astronaut crew Zhai Zhigang, Wang Yaping, and Ye Guangfu exited the cabin in turn in white space suits.
The first to leave the cabin was astronaut Zhai Zhigang. He smiled and showed strength in his composure. During the 14-year journey to the sky, he turned his love and persistence to the aerospace industry of the motherland into "fuel" for overcoming various difficulties.
Astronaut Wang Yaping was the second to leave the cabin. The mother who "picked the stars" came back. She smiled and waved to the crowd kindly. Wang Yaping's lectures in space on the space station have sown the seeds of aerospace dreams in the hearts of many students, which are now taking root.
The third person to leave the cabin was astronaut Ye Guangfu, who was smiling and full of confidence. For the first time, he felt the vast space, admired the beautiful planet, and enjoyed the great rivers and mountains of the motherland.
With their long-term and arduous efforts, they have drawn a successful conclusion to the Shenzhou 13 manned flight mission.
"01, feel good!" "02, feel good!" "03, feel good!" Hearing the familiar "feel good", the hall burst into warm applause again.
"Shenzhou 13 crew has worked hard! Congratulations, and I pay high tribute to you. We are waiting for your triumph in Beijing! See you in Beijing!" Listening to the wishes from the Beijing Aerospace Flight Control Center.
Li Liang, the chief designer of the manned spacecraft mission of the Beijing Aerospace Flight Control Center, said excitedly: "The Shenzhou 13 mission is the final battle of the key technology verification stage of the Chinese space station, and it is of great significance. The whole mission is perfect. , This time, we adopted the 'quick return plan'. We did a lot of experiments in the early stage to ensure that the astronauts can go home quickly in a safe and comfortable condition. I am very proud and proud to be able to participate in this mission!"
At this moment, everyone is immersed in joy, and all the hard work has turned into a sense of happiness and honor in their hearts at this moment. History will remember this day.
