Shenzhou 13 landed smoothly, and the astronauts returned to Earth safely

Shenzhou 13 landed smoothly, and the astronauts returned to Earth safely. At around 10:00 on April 16, Shenzhou 13 The return capsule of the Chinese manned spacecraft successfully landed at the Dongfeng Landing Site. The astronauts returned safely and feel good. Shenzhou 13 landed successfully and the astronauts returned to Earth safely. Shenzhou 13 landed smoothly, and the astronauts returned to Earth safely 1

At about 10 a.m. on April 16, they worked and lived in the space station assembly for 183 days, setting a new record for a Chinese astronaut in a single space mission. The crew of Shenzhou 13, which set a record dwell time, landed safely at the Dongfeng Landing Field in rapid return mode. The triumphant triumph of Shenzhou 13 marks that all the requirements for the scheduled mission of the Shenzhou 13 crew have been successfully completed, and the key technology verification phase of the China Space Station has also come to a successful conclusion.

As the second manned spacecraft launched during the key technology verification phase of China’s space station, it is also the Shenzhou spacecraft that has stayed in space for the longest time. During this mission, Shenzhou 10 The No. 3 manned spacecraft has achieved many firsts, constantly breaking new records for China's aerospace industry, and demonstrating the new heights of China's aerospace technology.

On October 16, 2021, the Shenzhou 13 manned spacecraft carried three astronauts and began a space journey that lasted more than half a year. During this mission, in order to adapt to different configurations of the space station assembly and different docking states of visiting spacecraft, Shenzhou 13 verified the radial rendezvous and docking with the space station in the forward, backward and radial directions for the first time. technology, and implemented radial rendezvous and docking with the radial docking interface of the core module of the space station.

After the docking, the docking flight time of Shenzhou 13 increased to 6 months. This is also the longest manned flight mission in my country to date. The Shenzhou 13 flight mission was assessed for the first time and passed It has verified the ability of astronauts on space station missions to stay in orbit for a long time.

Shao Limin, deputy technical manager of the manned spacecraft system project of the Fifth Academy of Aerospace Science and Technology Group, said in an interview with a reporter from the Global Times that astronauts on the International Space Station stay for an average length of time. That is, 5 to 6 months. If the residence time is extended further, the impact on the astronauts may be more prominent.

During the six-month stay of Chinese astronauts, key technologies of the Shenzhou 13 spacecraft were verified. "One of the most critical technical verifications of the Shenzhou 13 is the long-term The six-month docking is the biggest test for the Shenzhou spacecraft, because long-term stay in space has many uncontrollable factors that will affect the spacecraft, but these factors cannot be simulated on the ground, or The cost of simulation is unacceptable.

The biggest difficulty and challenge of the Shenzhou 13 mission is its long-term flight in orbit and its safe return after being affected by uncontrollable factors. The successful completion of this return mission is crucial to the success of the mission. For the Shenzhou spacecraft, it means the successful passing of key technology verification," Shao Limin said.

In order to deal with the possible failure of the spacecraft docked in orbit and unable to return, the space station also established an emergency rescue mission mode for the first time during the mission phase, using the "rolling standby" strategy to carry out the rescue mission after the previous launch. When a manned spacecraft is launched, the latter manned spacecraft is on standby at the launch site. The safety of the astronauts in orbit is ensured by docking the spacecraft in orbit and the standby spacecraft at the launch site. The Shenzhou 13 manned spacecraft carried out an emergency rescue launch standby mission for the first time.

During the Shenzhou-13 mission, the three astronauts on the Shenzhou-13 crew also successfully completed two extravehicular activities. Among them, astronaut Wang Yaping also performed a spacewalk and became the first Chinese woman to conduct extravehicular activities in space. This also laid the foundation and accumulated experience for Chinese female astronauts' extravehicular activities in the future.

In order to further improve the efficiency of return mission execution and shorten the implementation time of ground flight control, Shenzhou 13 also adopted the rapid return mode for the first time. By rationally cutting and adjusting the flight mission and compressing the operation time, the time required for return was reduced from the original 11 flight laps to 5 flight laps. Return time has been shortened from 17 hours to approximately 7.5 hours.

When talking about the original intention of adopting the fast return mode, Shao Limin said that in the previous return stage, we designed the return time to be about one day. Although this indicator meets the requirements, one day The flight time is still relatively long, especially in the Shenzhou 13 mission. The three astronauts have been in space for 6 months. They were transferred from the space station with a relatively spacious space to a manned spacecraft with a small space. , and they have to fly for one day, the comfort level felt by the three astronauts must be relatively poor.

"There is no limit to technological progress. We want the three astronauts to stay in the return capsule for as short a time as possible. Improve the comfort of astronauts returning," Shao Limin said.

It is understood that as the three astronauts of the Shenzhou 13 crew stayed for 6 months and returned safely, the next step will be a comprehensive assessment of the entire key technology verification of the space station. After the results meet the requirements, it will be transferred to Entering the assembly and construction stage of China’s space station.

At this stage, the Tianzhou 4 cargo spacecraft, Shenzhou 14 manned spacecraft, Experimental Module I and Experimental Module II, as well as the Tianzhou 5 cargo spacecraft and the Shenzhou 15th manned spacecraft will be launched in sequence. A total of six spacecrafts are planned to be built, and the construction of the T-shaped space station assembly is finally completed. The entire assembly and construction process will last about seven months. Shenzhou 13 landed smoothly, and the astronauts returned to Earth safely 2

When the Shenzhou 13 return capsule landed, was the first person to greet the astronauts a camel?

When Chang'e-5 returned home, the rabbit was the first to greet it! This year when the God-13 astronauts returned home, little animals were the first to greet them!

According to China Aerospace Science and Technology Corporation, at around 10:00 on April 16, the return capsule of the Shenzhou 13 manned spacecraft successfully landed at the Dongfeng Landing Field. Astronauts Zhai Zhigang and Wang Yaping , Ye Guangfu returned safely and feels good!

The flight crew worked and lived in the space station assembly for 183 days, setting a new record for the continuous flight time of Chinese astronauts in orbit. At this point, the key technology verification phase of the Chinese space station has been completed and will soon be transferred to on-orbit assembly and construction. stage.

In the early morning of today (16th), the Shenzhou 13 manned spacecraft successfully separated from the Tianhe core module of the space station at 0:44.

At about 9 o'clock, the spacecraft adjusted its attitude for the first time before returning to the brake. Then the orbital module and the return capsule were successfully separated. The spacecraft returned to the brake engine and ignited. The return module separated from the propulsion module. The spacecraft re-entered the atmosphere. The parachute opened at an altitude of about 10 kilometers above the ground and finally landed successfully.

Compared with the Shenzhou 12 manned spacecraft, the Shenzhou 13 manned spacecraft uses the rapid return mode to shorten the return orbit of the earth from 18 times to 5 times without changing the hardware and software. , the return time is shortened by nearly 20 hours. Shenzhou 13 landed smoothly, and the astronauts returned to Earth safely 3

After 6 months of hard work, the return capsule of Shenzhou 13 has landed, and the ground rescue and evacuation personnel are ready, and The "kitchen" is also essential.

We Chinese have a saying: Get on the bus and get off the dumplings. One of the complex facilities being built on site is a kitchen, which will be used for living in outer space 6 The three astronauts who took the month sent a bowl of hot noodles!

Human beings are, after all, advanced organisms. It is really a pleasure and gratification to eat a good meal. Astronauts are no exception. They haven’t eaten freshly cooked meals over an open fire in half a year. .

In the sky, the most "terrestrial" thing astronauts can eat is mustard. After successfully landing, the astronauts' expectations of eating noodles are also very down-to-earth. , eating noodles can make them feel like they are "really home", and this feeling is what everyone wants.

Exactly what the noodles look like can only be seen at noon. Currently, the unloading operation needs to last an hour before the astronauts can be seen.

Preliminary work such as microbial testing and health testing needs to be carried out with caution.

This time, it is fast, stable and accurate, which is a proof of China's aerospace technology. It can return quickly in 5 circles, the opportunity to open the parachute is also perfect, and the landing point is very precise.

The most ideal thing is that we can see that the astronauts in the cabin will land in an upright posture after returning to the ground. This is very helpful for the astronauts in the cabin to adapt to the earth's gravity faster, and it is also a proof of technology that will no longer allow The return capsule rested on the ground.

In 2 hours, lunch time will be here. Readers who follow China’s aerospace industry may wish to cook a bowl of noodles at home and eat noodles with the astronauts. It is also a happy thing.

Welcome the astronauts home, another great victory for China’s aerospace industry.
