　　On December 4, Shenzhou 14 astronauts Chen Dong, Liu Yang, and Cai Xuzhe embarked on a journey back to Earth after a 183-day business trip on the Chinese space station.

The spacecraft's return module dragged a yellow tail flame, and flew across the night like a shooting star, escorting the astronauts home all the way.

　　"The Yellow River found the target." At about 19:48 that night, the return module of the spacecraft had flown over the motherland, and the measurement and control stations in various places relayed the "discovered target" and set up a "ladder" for the astronauts to return home.

When the return capsule of the spacecraft left the "black barrier area" and flew to about 10 kilometers from the ground, the return capsules opened their parachutes one after another and began to decelerate.

　　At 20:09, the return capsule successfully landed at Dongfeng Landing Field and was in a horizontal state.

After the spacecraft landed, it sent out a radio beacon signal to tell the search and rescue personnel "I am here". At the same time, the flashing lights on the "shoulder" of the return capsule kept flashing, like a lighthouse in the dark night, making it easier for search and rescue personnel to find the return capsule.

　　This is the first time in 17 years that Chinese astronauts returned at night again.

The low visibility at night makes it more difficult for search and rescue missions to find targets and reach the scene quickly.

The landing site has prepared all kinds of lighting equipment needed for night search and rescue of astronauts. The ground vehicles are equipped with searchlights, strobe lights, and fluorescent flags. The on-site search and rescue personnel are also equipped with strong flashlights and head-mounted lights.

　　Soon after the return capsule landed, the search and rescue recovery air unit took the lead in arriving at the landing site of the return capsule, and carried out work such as detection of harmful substances, erection of portable communication facilities, and opening of the hatch door.

It can be seen from the video that under the illumination of various lighting equipment, the landing spot is as bright as day.

At around 20:25, the hatch opened, and the astronaut's voice of "feeling good" came from the cabin.

　　Subsequently, Chen Dong, Liu Yang, and Cai Xuzhe were successively carried out of the capsule by the medical supervision and insurance personnel, and carried to the seats in front of the reentry capsule. During the process, the three astronauts did not forget to smile and wave to everyone.

　　Chen Dong, who was the first to go out of the cabin, said to the camera: "After six months of busy and fulfilling space travel, I was fortunate to witness the completion of the basic configuration of the space station. We returned to the embrace of the motherland like a meteor, and we are proud of the great motherland." Liu Yang said directly Sighing, "I can't forget the palace in the sky, and I miss the homeland of the motherland." Cai Xuzhe, who was finally out of the cabin, said: "The first six-month flight, the galaxy is brilliant, and you can see it at a glance. I hope to return to the space home one day."

　　The temperature at Dongfeng Landing Site at night has dropped to minus ten degrees Celsius.

The cold weather is not only a test for the search and rescue team, but also a challenge for the Shenzhou 14 crew.

After leaving the cabin, the medical supervision and medical insurance personnel quickly wrapped the astronauts with thermal quilts and thermal insulation blankets, and the medical supervision and medical insurance vehicles came to the side of the return capsule in advance to wait for the astronauts. It can provide astronauts with a place with a suitable temperature under extremely cold conditions.

　　The medical supervision and medical insurance vehicle was used for the first time during the Shenzhou 13 mission. It is the first "temporary home" for astronauts after returning to Earth. It is equipped with toilets and microwave ovens, allowing astronauts to eat hot meals and drink at the landing site. Run hot water and wash with hot water.

　　It is reported that the crew of Shenzhou 14 will enjoy the first meal after returning to the earth in the medical supervision vehicle. The staple food includes noodles, millet porridge, and flower rolls. The dishes include mutton, tomato sirloin, and fried potato shreds. , grapefruit and freshly squeezed corn juice.

　　After the astronauts left the cabin, the on-site staff continued to stay at the landing site to hand over the "luggage" brought back by the astronauts from space. In addition to their personal belongings, there were also a batch of medical science experiment samples, which could allow the ground research team to better understand Learn about the changes that occur in the human body during life in space.

According to experts, the "luggage" includes astronauts' blood, urine, and saliva, and researchers can study human adaptability to the environment at a deeper level, which also enables China to have its own genetic resource bank for environmental adaptation in orbit.

　　The three astronauts returned to the ground safely to draw a successful conclusion to the mission of Shenzhou 14.

During the in-orbit period, they cooperated with the ground to complete the assembly and construction of the "T" basic configuration of the Chinese space station, completed the on-orbit handover with the Shenzhou 15 astronauts for the first time, and witnessed the world record for the fastest rendezvous and docking of the cargo spacecraft and the space station, etc. historic moment.

In the follow-up, they will undergo a half-year recovery training, and after observation and evaluation, they will transfer to normal training.
