God 14th astronauts can only drink a bottle of "mineral water" for the first time in space out of space

"I have been out of the cabin, it feels good!" At 0:33 on September 2, 2022, Beijing time, after about 6 hours of out of the cabin, Shenzhou 14 astronauts Chen Dong, Liu Yang, Cai Xuzhe closely collaborated to complete the out of the cabin out of the compartment During the event, all the established tasks were set, and Chen Dong and Liu Yang safely returned to the test compartment, and the outlet activities were successful.

This is the first time that my country's astronauts have implemented off -compartment activities from the outlets of the air gates in the experimental compartment. It is also the first time that the astronauts Chen Dong and Liu Yang have performed the outlet activities. In addition, the first use of small robotic arm auxiliary outlets can be described as newcomers, which can be described as newcomers. New cabin, new state.

Despite the great challenges and risks, through the collaboration between the heavens and the earth, the wonderful performance of the astronauts is a complete end of the "new" state of the cabin mission.

6 hours of space out of the cabin, God 14th astronauts can only drink a bottle of "mineral water"

For Shenzhou 14 astronauts Chen Dong and Liu Yang, although both have experienced space flight experience more than once, it is the first time to perform the outlet mission.

In space out of space, astronauts are "exposed" in outer space, facing the temperature difference between temperature difference between 200 degrees Celsius and harsh conditions such as space radiation and vacuum environment. As a space suit that guarantees the safety of life and supports off -cabin activities, although it is safe and reliable, the astronauts must control the physical condition in this "humanoid aircraft" of more than 100 kilograms, and perform space walking, climbing and refined Outside operation is not what you want, but it is actually difficult.

The first out -of -the cabin event in Shenzhou 14 is also the first out of the space station construction stage. Earlier, through the four out of Shenzhou 13 and Shenzhou 14, the performance of the space uniforms outside the cabin was fully verified, and the capabilities of the space staff for a long time. The capability of the cabin means that the space station will be a space home that can be represented and upgraded.

The first out -of -the cabin event of Shenzhou 14 faced many new status and new situations, favorable conditions and challenges coexisting risks. For the first time, the astronauts came out from the air gate, and the outlet door of the air gate was larger. It expanded from the 85 cm cabin mouth diameter to 1 meter, and the outlet and mouth were more "spacious". The robotic arm is a robotic arm equipped with the sky cabin, but there has been no actual experience in experience. The communication coverage between heaven and earth has been further improved, which is relatively sufficient for the support of heaven and earth and the ground to heaven. However, these new states also need to be prepared in advance and respond on the spot. For example, this outlet event was carried out in the state of asking the space station to join the space station. The size of the space station has changed. The spacemen face a larger and more complex aircraft combination.

On the afternoon of September 1st, the astronauts closed the door of the section of the sky cabin, and then Chen Dong and Liu Yang entered the space uniforms outside the cabin to prepare before the outlet. At 18:26, Chen Dong successfully opened the cabin door of the Tiantian Experimental Counterbill. At 19:09, Chen Dong and Liu Yang successfully came out of the cabin. Cai Xuzhe cooperated in the core cabin to support two out -of -class spacemen to conduct off -cabin operations.

For the 6 -hour outlet event, the heavens and the earth are closely coordinated, and the inside and outside the cabin cooperate closely. It has completed the task of installing the installation of the skycase expansion pump group, the rising panoramic camera of the sky compartment, and the autonomous emergency return verification of the cabin. The ability of astronauts and small robotic arms to work, and verified the functional performance of the relevant supporting equipment related supporting devices in the experimental compartment and outlet activities.

High -intensity out of the cabin in a closed space suit, the physical consumption is huge. But in these 6 hours, except for carried about 500 ml of water, the two Shenzhou No. 14 astronauts who were out of the cabin did not supplement. It can be said that every action that astronauts do in the sky are considerations and courage.

The outlet activities were successfully completed. Before Chen Dong and Liu Yang were preparing to return to the air gate, the ground support team praised the wonderful performance and collaboration spirit of Shenzhou 14 astronauts. The camera beckoned to record this precious moment.

At the same time, Chen Dong said that for the first time out of the air gate, the first small robotic arm was enabled, and it was Liu Yang's first out of the cabin. For the first time, we felt the beautiful scenery outside the cabin. I felt the difficulty of out of the cabin, and I felt that China Space Station continued to grow. The most important thing was to feel the encouragement, support and help of ground personnel.

Liu Yang said that heaven and earth are one step forward. Although it is full of hardships and challenges, a small step forward is a big step in dreams. China Space Station will always be worth looking forward to!

Cai Xuzhe also thanked the ground team and the majority of science and technology workers for their support for this outlet.

When Liu Yang said, "Happy Mid -Autumn Festival in advance", the ground team also answered immediately, "You also have to eat moon cakes." The dialogue and details between these worlds and earth suddenly made the space out of space warm.

For the first time from asking the Tianyan Experimental Counter

When the Shenzhou 12 and Shenzhou 13th multiplication group out of the cabin, the cabin door that passed the cabin was located at the outlet of the core compartment of the space station, with a caliber of the cabin door 85 cm. In this task, Shenzhou 14 Aerospace officer "went out" from the air gate of the Tianshi experimental compartment for the first time. The caliber of this cabin door reached 1 meter, allowing astronauts to be more calm in the case of the space uniforms outside the cabin. Carry the equipment "out of the house and travel space".

However, the seemingly simple geometric size is actually a balance between "rigid" and "soft". Under the condition of maintaining the unchanged operation of the astronauts, the cabin door with a caliber of 1 meter was sealed, and the development difficulty was self -evident. Responsible for the structure and institutional team of the Fifth Hospital Space Station of China Aerospace Science and Technology Group, which was developed, and innovated for this. From a technical point of view, as a complex product in the spacecraft mechanism, it covers sealing, transmission, locking, guidance, lubrication, human machinery and other disciplines. Facing such complex scientific research products, the operation process of astronauts will be operated by the operation process of astronauts. Isn't it complicated? After the exquisite design of the cabin design team, before the astronauts are out of the cabin, they only need to use the supporting handle on the door door to rotate and unlock them. Use the helping agency to eliminate the pressure. Pull the door handle to complete the opening of the opening door. The cabin door is also equipped with a tailor -made cabin door protection cover to ensure the safe use of the Cabin Gate in all aspects.

In addition, a series of space equipment such as "safety rope", "lighting lights", and off -cabin maintenance tools are guaranteed to provide a guarantee for the smooth out of the cabin.

Safety rope is the "lifeline" connected to the space officer and the space station. During Shenzhou VII mission, astronauts Zhai Zhigang completed the first space out of my country's space. The safety rope used when the cabin was out of the cabin was a fixed length line, which was only more than 1 meter in length. In the construction task of the space station, astronauts must complete the outlet tasks such as the installation and maintenance of the space station. The outlet range is larger, the operation difficulty is more difficult, the safety requirements are stricter, and the long -term and scalable safety rope institutions require. During the outlet process, this safe rope can ensure a safe connection between the astronauts and the space station compartment of more than 10 meters without the movement of hooking and interference in spacemen in space uniforms. , Test the tests such as spatial irradiation and space particles. The development team of the 529th Factory of the Fifth Hospital of China Aerospace Science and Technology Group carried out the research and development of a new type of telescopic safety rope, and innovatively proposed a clever design solution. Tens of thousands of times in the narrow space, repetitive ordeal.

Since the successful entry of the space station on June 5, 2022, Beijing time, Shenzhou No. 14 Aerospace Commissioner has been working and living in the orbit for about 89 days. Experimental cabinet unlocking and testing, small robotic arm unlocking and rail testing, space station combination management and other work have carried out daily work such as rail medical examination, weightless protection and exercise, spatial scientific reality (trial) inspection, etc. Disciples, small robotic arm operation, medical rescue drills, etc. are in rail training programs.
