On the afternoon of April 16, three Shenzhou 13 astronauts arrived in Beijing safely. As soon as Wang Yaping got off the gangway, her daughter in a small red dress greeted her and handed her mother a large bouquet of flowers. After hugging his daughter, Wang Yaping immediately took out a "star" and gave it to his daughter with a smile.
The "star-picking mom" is back, the space hero is back. Astronauts Zhai Zhigang, Wang Yaping, and Ye Guangfu successfully concluded their "space business trip," drawing a satisfactory end to the longest space manned flight of China's aerospace industry so far.
From the space capsule to the first orbit through remote operation to complete the docking of the cargo spacecraft and the space station, from the first spacewalk of Chinese female astronauts to the record for the longest space stay of Chinese astronauts in a single mission... Each of the 183 days in orbit is marked with a new altitude for China's spaceflight. As a key mission, the successful Shenzhou 13 mission means that the key technology verification stage of the Chinese space station has ended and officially entered a new stage of assembly and construction in orbit.
Open the umbrella, land on the ground, get out of the cabin... Every key node makes people hold their breath, and the completion of each command action is exciting
"Warmly celebrate the complete success of the Shenzhou 13 manned mission" - At the Beijing Aerospace Flight Control Center, when the large screen with various flight parameters and real-time pictures switched to the big red screen celebrating success, thunderous applause sounded at the scene.
In the process of the return of Shenzhou 13, every key node made people hold their breath, and the completion of each command action was exciting: the main parachute of the return capsule was opened, the red and white umbrella flowers bloomed instantaneously in the air, and the flight control hall applauded warmly; the return capsule landed on the ground, stirring up billowing smoke and dust on the Gobi Desert, and a desert camel ran in front of the camera, and the surprise and applause sounded at the same time; after the 3 astronauts took turns to "report safety", there was another round of applause...
Thousands of miles away, the Dongfeng landing field located in the territory of the Ejin Banner of the Alxa League in the Inner Mongolia Autonomous Region is the "foothold" of the astronauts, and the aerospace search and rescue personnel on standby at the Dongfeng landing site are the first "earthlings" that the astronauts see when they go home.
Flag raiser Feng Yi was the first to rush to the place closest to the return capsule and the medical supervision and medical rescue plane, set up the base, twisted the flagpole, and unfurled the national flag, and the five-star red flag flew in the wind, hunting and hunting. At the same time, the establishment of warning zones, the erection of portable stations, and the detection of nohydrazine in the cabin are also carried out in an orderly manner.
"I'm going to get ready to open the hatch, so be safe." The opening hand Su Liming skillfully balanced the air pressure inside and outside the cabin, grasped the opening handle and rotated it 140 degrees counterclockwise, and then slowly opened the hatch. After the return hatch door opened, the medical supervision and medical insurance personnel confirmed that the astronauts were in good health.
"Beijing, I am Shenzhou 13, I have landed safely, the return capsule is standing upright, 01 feels good!" "02 Feel good!" "03 Feel good!"
In the flight control hall, the chief dispatcher "Beijing Understand" replied: "Congratulations to Shenzhou 13, you have worked hard, and I would like to pay you high respect!" We greet you in Beijing, see you in Beijing! ”
Behind the "feeling good" is the solid support of the aerospace science and technology force, and multiple "firsts" have added confidence to the key technical verification of the space station
With the help of medical supervision and medical insurance personnel, Zhai Zhigang first came out of the cabin and sat on the astronaut-specific seat prepared for him by the ground personnel. "Felt very good, report to the motherland and the people! We have successfully completed our mission and are now back on the ground. Zhai Zhigang smiled and waved, and applause rang out at the scene.
From "I am out of the cabin and feel good" when I walk in space" to "I feel very good" after landing, behind the self-confidence of astronauts is the solid support of aerospace science and technology forces.
Outside the cabin, the astronauts wore the self-developed "Flying Sky" extravehicular space suit and "showed their skills" in the highly risky space outgoing activities; inside the cabin, the space broadband that was several times the speed of the 5G network supported the astronauts to give a wonderful lecture in the 400-kilometer-high "Tiangong Classroom". At the time of departure, the supplies that were originally carried by the astronauts in the spaceship have now been delivered by the Tianzhou Cargo Spacecraft; when returning, the trip home, which originally took nearly 1 day, is now shortened to several hours... Chinese astronauts have continued to tackle key problems, broken through key technologies, and made brilliant achievements one after another, and China's aerospace industry has become more and more "feeling good".
"For the first time, during a six-month residency period, we validated the key technologies of the Shenzhou XIII spacecraft." Shao Limin, deputy technical manager of the manned spacecraft system project of the Fifth Academy of China Aerospace Science and Technology Corporation, said in an interview that one of the most critical technical verifications of Shenzhou 13 is a 6-month long docking. For the Shenzhou spacecraft, the safe return after a long-term orbital flight is the biggest test.
Shao Limin said that there are many uncontrollable factors in long-term stays in space, and the ground cannot fully simulate the on-orbit environment. "To ensure the reliability of the life of the spacecraft, it must be verified in orbit, which is not only more scientific, but also makes the researchers more confident." The successful completion of the return mission is the smooth passage of key technical verification for the Shenzhou spacecraft. ”
"In addition to the verification of key technologies such as long-term orbital residency, outgoing activities, and module transposition, astronauts have also conducted a large number of scientific experimental studies." Wu Dawei, deputy chief designer of the astronaut system of the manned space engineering and director of the general office of aerospace medical engineering of the astronaut scientific research and training center, told reporters that the Shenzhou 13 astronaut crew carried out the collection and analysis of various types of work and life data, human factors technology and aerospace medical experimental research, as well as the research of the space application system experimental project of the Chinese Academy of Sciences, and obtained a large amount of space science experimental data, laying a good foundation for the establishment of the National Space Laboratory.
Astronauts will undergo six months of physical recovery, and the Chinese space station will move to the on-orbit assembly and construction phase
After the medical supervision and medical insurance personnel determined at the first time, the three astronauts were in a normal physical state.
The astronaut's physical condition after returning is relatively good, which is inseparable from the optimization and strengthening of the astronaut's weightlessness prevention and control exercises in orbit. "One month before returning, they began to strengthen physical exercises, and also used corresponding physical auxiliary facilities for adjustment and support, focusing on strengthening cardiovascular reserve capacity and endurance, so that astronauts can better re-adapt to the gravitational environment of the earth after 6 months of weightless flight." Wu Dawei said.
It is understood that the medical supervision and medical insurance vehicle independently developed by the mainland was used for the first time in the search and rescue return mission of Shenzhou 13. This car has two functions: one is the medical supervision and medical insurance function, where the astronauts can carry out life care, change clothes, eat, etc., and the other is the medical rescue function, and the car is equipped with various types of medical equipment.
Wu Donghui, captain of the astronaut medical rescue team of jiuquan satellite launch center hospital, told reporters that in the past, the medical supervision and medical insurance after the return of astronauts was carried out on the helicopter, and now the medical supervision medical insurance vehicle space is more spacious, independent and convenient, providing a warmer and more comfortable environment for astronauts.
After the three astronauts arrived in Beijing, the recovery work also began. The recovery process lasts for half a year and is divided into three stages: isolation recovery, convalescence recovery and observation recovery. Before that, astronauts will have to undergo a week-long three-stage quarantine.
The stars are vast and the exploration is endless. The three astronauts of Shenzhou XIII "went home from work", but the construction of the Chinese space station did not "stop work". 2022 is the year of decisive victory in the construction of the space station, the task is still arduous, the challenge is still not small, but the Chinese to space, into the space station era of the steps are still sonorous. According to the mission arrangement, this year we will organize the implementation of 6 flight missions such as the space station sky capsule, the dream space capsule, the cargo supply, and the manned flight, complete the construction of the space station in orbit, and build a national space laboratory with stable operation in orbit. At present, the astronaut crew for the two manned flights in the construction phase of the space station has been selected and is conducting mission training.
