Spring is in full bloom, and business is booming in Beijing Space City. After several months, the Dongfeng landing field of the Jiuquan Satellite Launch Center once again welcomed the astronauts home.
"Attention, I am Beijing, and the following call points are all ..." At 8:08 on April 16, Beijing issued a return search and rescue mission. The road sealing and control detachment, the joint search and rescue detachment, the search and rescue recovery support detachment, and the search and rescue reserve detachment have successively arrived at the standby point and are ready to welcome the spacecraft home.
On the screen in the hall of the Beijing Aerospace Flight Control Center, it can be seen that the three astronauts in the spacecraft are waiting in a tight line, and they sometimes adjust their posture and sometimes confirm the technical status with the ground.
"The engine is powered on and the brakes are back on." With a dazzling flash of light flashing on the big screen, the speed of the spacecraft gradually slowed down, which meant that the return capsule carrying the three astronauts was about to sail back to the Earth home.
"Beijing, the Eagle reports, the air detachment takes off, goes to the standby airspace, and the report is complete." The reporter saw from the big screen that the army green helicopter soared like an eagle spreading its wings and shining with the earth-yellow Gobi.
The 6 months of "space business trip" have set a new record for the length of time spent by Chinese astronauts in orbit, and have 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 support time is getting longer and longer, we are constantly looking for solutions to improve capabilities." Zheng Yonghui, engineer of the overall office of the Beijing Space Information Transmission Center, told reporters that in the past 6 months, all the scientific and technological personnel of the center have continuously witnessed the Shenzhou 13 crew refreshing China's height in space, and while successfully completing the task, they also deeply feel the glory and pride of devoting themselves to the aerospace industry of the motherland.
"Propulsion chamber separation!" "The spacecraft entered the atmosphere!" The Beijing Aerospace Flight Control Center issued a return command through the ground measurement and control station, and a voice order was issued, which touched the hearts of everyone at the scene.
Immediately after, the return capsule enters the black barrier area, where the plasma layer caused by the violent friction between the surface of the capsule and the atmosphere forms an electromagnetic barrier, and the communication between heaven and earth is temporarily interrupted. In just a few minutes, everyone in the hall stared at the screen with bated breath.
"Return to the cabin out of the black barrier." The camera switches to the vast Dongfeng landing field, and the happy news comes from the intercom. The spacecraft was speeding towards the landing field along a predetermined trajectory.
"It's exciting to go back!" Zhai Zhigang's calm and self-assured tone came from the signal, which caused laughter in the flight control hall.
On the vast Gobi Desert, the main parachute opened, the return capsule threw a heat-proof bottom, 5 helicopters began to close and fly, and the ground detachment and the mobile search and rescue detachment went out to search. Eagles fly high, warriors gallop, and the East Wind landing field plays a symphony of search and rescue coordinated by heaven and earth.
"Bang!" At 9:56, with a loud noise, the return capsule landed safely and finally returned to the embrace of the earth. At the same time, the establishment of a warning zone, the erection of portable stations, and the detection of nohydrhydrazine in the cabin were carried out in an orderly manner.
"I'm going to get ready to open the hatch, so be safe." Su Liming, 27, is the driver of the Shenzhou 13 search and recovery mission, and his young face is full of calmness and confidence. "Welcome home!" After balancing the air pressure inside and outside the cabin, Su Liming slowly opened the hatch, and the Shenzhou 13 astronauts left the capsule in turn in white spacesuits such as Zhai Zhigang, Wang Yaping, and Ye Guangfu.
The first to leave the capsule was astronaut Zhai Zhigang, who was smiling and calm and full of strength. In the 14 years of flying road, he turned his love and perseverance for the motherland's aerospace industry into "fuel" to overcome various difficulties.
The second person to leave the capsule was astronaut Wang Yaping, and the mother of the "star picking" returned, smiling and waving kindly to the crowd. Wang Yaping's lecture in space on the space station has sown the seeds of space dream in the hearts of many students, and now it is taking root.
The third person to leave the capsule was astronaut Ye Guangfu, who was smiling and full of confidence. For the first time, he felt the vastness of space, admired the beautiful planet, and enjoyed the great rivers and mountains of the motherland.
With long and arduous efforts, they drew 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 resounded with warm applause again.
"Shenzhou Thirteen crew is hard! Congratulations and high esteem to you. We are waiting for your triumph in Beijing! See you in Beijing! The wind was warm, and the warm sun sprinkled on the smiling faces of the three astronauts, who listened to the wishes from the Beijing Aerospace Flight Control Center.
Li Liang, the overall 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, which is of great significance. The whole mission was perfect, and this time with the 'fast return program', we did a lot of tests in the early stages to ensure that the astronauts could quickly return home in a safe and comfortable situation. I am very proud and proud to be on this mission! ”
At this moment, everyone is immersed in joy, and all the hard work has become a sense of happiness and honor in their hearts at this moment. History will remember this day.
