Shenzhou XIII landed successfully and the astronauts returned to Earth safely. On April 6 10 or so, the return capsule of Shenzhou 13 manned spacecraft landed successfully at the Dongfeng landing site, and the astronauts returned safely, feeling good. Shenzhou XIII landed successfully and the astronauts returned to Earth safely.
Shenzhou XIII landed successfully and the astronauts returned to Earth safely. 1On the morning of April 6th, June, around 10, the Shenzhou XIII crew worked and lived in the space station assembly for 183 days, which set a new record for the space residence time of China astronauts in a single mission and landed safely at the Dongfeng landing site in a quick return mode. The triumph of Shenzhou XIII marks the successful completion of all the requirements for the scheduled mission of Shenzhou XIII crew, and the successful completion of the key technology verification phase of China Space Station.
As the second manned spacecraft launched in the key technology verification stage of China Space Station, shenzhou spaceship, who has stayed in space for the longest time, has achieved many firsts in this mission, constantly setting a new record for China's space, and showing a new height of China's space science and technology.
20211kloc-0/6, the Shenzhou XIII manned spacecraft with three astronauts began its space journey for more than half a year. In this mission, in order to adapt to the different configurations of the space station assembly and the different docking States of the visiting spacecraft, and realize the forward, reverse and radial rendezvous and docking and separation with the space station, Shenzhou XIII verified the radial rendezvous and docking technology for the first time, and implemented the radial rendezvous and docking with the core module of the space station.
After docking, the docking flight time of Shenzhou XIII increased to six months, which is also the longest manned mission in China so far. For the first time, the Shenzhou-13 mission verified the long-term in-orbit resident ability of the astronauts of the space station mission.
Shao Limin, deputy manager of manned spacecraft system engineering technology in the Fifth Academy of Aerospace Science and Technology Group, said in an interview with the Global Times that astronauts on the International Space Station usually stay for 5-6 months. If the stay time is extended, the impact on astronauts may be more prominent.
During the six-month stay of China astronauts, the key technologies of Shenzhou XIII spacecraft were verified. "The most critical technical verification of Shenzhou XIII is the six-month docking, which is the biggest test for shenzhou spaceship, because there are many uncontrollable factors in space that will affect the spacecraft for a long time, and these factors cannot be simulated on the ground, or the cost of simulation is unacceptable.
The biggest difficulty and challenge of Shenzhou XIII mission is the long-term in-orbit flight and the safe return after being affected by uncontrollable factors. The successful completion of this return mission is a successful verification of key technologies in shenzhou spaceship. Shao Limin said.
In order to cope with the possible faults of the docking spacecraft in orbit, the emergency rescue mission mode was established for the first time in the mission phase of the space station, and the strategy of "rolling standby" was adopted. When the former manned spacecraft is launched, the latter manned spacecraft is on standby at the launch site, and the safety of astronauts in orbit is jointly guaranteed by the docked on-orbit spacecraft and the standby spacecraft at the launch site. Shenzhou 13 manned spacecraft is the first time to carry out emergency rescue launch standby mission.
During the Shenzhou-13 mission, three astronauts of the Shenzhou-13 crew also successfully completed two extravehicular activities. Among them, astronaut Wang Yaping also walked in space, becoming the first woman in China to carry out extravehicular activities in space, which laid a foundation for the future extravehicular activities of China female astronauts and accumulated experience.
In order to further improve the efficiency of the return mission and shorten the implementation time of ground flight control, Shenzhou XIII also adopted the fast return mode for the first time. By adjusting the flight mission reasonably and compressing the running time, the time required for returning from the original 1 1 flight circle is reduced to five flight circles. The return journey time is shortened from 17 hours to about 7.5 hours.
When talking about the original intention of adopting the fast return mode, Shao Limin said that in the previous return stage, the return time we designed was about one day. Although this index meets the requirements, the flight time of one day is still relatively long, especially in the Shenzhou-13 mission. Three astronauts have been in space for six months, and they will fly for one day. The comfort of the three astronauts is definitely poor.
"There is no end to technological progress. We hope that the three astronauts will stay in the return capsule as short as possible to improve the comfort of the astronauts. " Shao Limin said.
It is understood that with the three astronauts of Shenzhou 13 staying for six months and returning safely, the next step will be to comprehensively evaluate the entire key technology verification of the space station. After the results meet the requirements, it will be transferred to the assembly and construction stage of China Space Station.
At this stage, the Tianzhou-4 cargo spacecraft, Shenzhou 14 manned spacecraft, Experiment No.1 and Experiment No.2, Tianzhou-5 cargo spacecraft and Shenzhou-15 manned spacecraft will be launched in turn, and finally the T-shaped space station will be assembled. The whole assembly and construction process will last about 7 months.
Shenzhou XIII landed successfully and the astronauts returned to Earth safely. When the return capsule landed, the first one to greet the astronauts was a camel?
When Chang 'e V came home, the rabbit was the first to see him! This year, the thirteen astronauts came home, and the small animals were the first to meet them!
According to the news of China Aerospace Science and Technology Corporation, on April 6 10, the return capsule of Shenzhou 13 manned spacecraft landed successfully at the Dongfeng landing site, and the astronauts Zhai Zhigang, Wang Yaping and Ye Guang Fu returned safely, feeling good!
The flight crew has been working and living in the space station complex for 183 days, setting a new record for the continuous on-orbit flight time of China astronauts. At this point, the key technology verification stage of China Space Station has been completed and will soon be transferred to the on-orbit assembly and construction stage.
This morning (16), the Shenzhou 13 manned spacecraft was successfully separated from the space station and the core module at 0: 44.
At about 9 o'clock, the spacecraft adjusted its attitude for the first time before braking, and then the orbital module and the return module were successfully separated. The spacecraft returned to the brake engine for ignition, and the return module was separated from the propulsion module. The spacecraft re-entered the atmosphere, opened its umbrella at a height of about 10 km from the ground and finally landed successfully.
Compared with Shenzhou-12 manned spacecraft, Shenzhou-13 manned spacecraft adopts fast return mode, which shortens the return flight around the earth from 18 to 5 laps and shortens the return time by nearly 20 hours.
After half a year's efforts, the Shenzhou 13 return capsule has landed, the ground rescue and assistance personnel are ready, and the "kitchen" is also essential.
We have a saying in China: Get on the bus and jiaozi get off. One of the comprehensive facilities being built at the scene is a kitchen, which will send a bowl of hot noodles to three astronauts who have lived in an alien world for six months!
After all, humans are advanced creatures. Eating a good meal is really a pleasure, and astronauts are no exception. They haven't eaten a meal cooked with an open flame for half a year.
In the sky, the most "grounded" thing that astronauts can eat is mustard tuber. After the successful landing, the astronauts' expectations for eating noodles were also grounded. Eating noodles can make them feel "really home". This feeling is what all employees want.
What is the specific surface? I can't see it until noon. At present, it takes you 1 hour to go out to see the astronauts.
The preliminary work such as microbial detection and health detection needs to be carried out seriously.
This time it is fast, steady and accurate, which is a proof of China's space technology. After 5 laps, the ball can be quickly returned, the opening time is perfect, and the landing point is very accurate.
Ideally, we can see that the return capsule landed upright, which is very helpful for astronauts in the capsule to adapt to the gravity of the earth more quickly, and it is also a technical proof, so that the return capsule will not rest on the ground again.
In two hours, it will be lunch time. Readers who are concerned about China Aerospace may wish to cook noodles at home and eat noodles with astronauts. This is also a kind of fun.
Welcome the astronauts home, which is another great victory for China's space industry.
