The first out of the cabin of the Fourteenth multiplier and the Chinese Space Station will be completed ... Building a aerospace power in the dream star

Chai Yaxin, the website of the Central Commission for Discipline Inspection, reported, "Hello everyone! I'm Chen Dong, I have been out of the cabin, it feels good!" After a few months, the familiar voice came back from Tiangong. On September 1st, Shenzhou No. 14 Aerospace Micro took the first out of the cabin. This is the fifth out of the cabin out of the China Space Station, and it is also the first out -of -the cabin mission after the Chinese space station entered the construction stage.

This time there are "three new" -newcomers, new arms and new cabins. Among them, "newcomers" refers to the first time the space officer Chen Dong and Liu Yang performed the task of outlet activities. The cabin is implemented outside the cabin.

In this task, with the support of Chen Dong and Liu Yang, with the support of the small robotic arm, they completed the installation of the expansion pump group and the panoramic camera lifting of the test compartment. They also carried out the capacity verification of an emergency return emergency return on the cabin.

The robotic arm is one of the "stars" components of the space station. When the first four out of the cabin, you can see a dexterous and powerful robotic arm assists of the "arm" of the "arm" -that is the big robotic arm of Suitian and the core cabin. Today, the "small arm" is shining.

The head is small, and the flexibility and accuracy are even better. According to Lin Xiqiang, a spokesman for China Manned Aerospace Engineering and deputy director of the China Manned Aerospace Engineering Office, the small robotic arm configured by the Tiangtian experimental cabin is more delicate and flexible, and the weight and length are about half of the arm. At 1/8 of the arm, the end positioning accuracy is also higher than the large arm, which can complete the fine operation with higher accuracy requirements. It can also be captured by large robotic arms to form a combined robotic arm, and the coverage of off -cabins will be wider.

Qi Tian's experimental cabin is the first experimental cabin section of China Space Station, and it is also the main cabin section of the scientific research work and station work of astronauts. Earlier, Shenzhou 12 and Shenzhou 13 astronauts came out of the compartment of the nodes of the heavens and the core cabin. This time, the two astronauts came out of the air gate of the test compartment.

Compared with the cabin door with a diameter of 85 cm in the nodes, the air gateway door of the test cabin is larger, up to 1 meter in length. Because there is no need to take into account the function of the connection to the aircraft, asking the weather in the weather gate is relatively flat and the volume is larger. The astronauts are more stretched when the cabin preparations are prepared here and returned outside the cabin.

"The space of the Tianhe Node Counter is relatively small, and the space for people's activity is only about 10 cubic meters, and the weather gate is close to 15 cubic meters." Gao Jie, the overall deputy director of the System of the Five Hospital System of Aerospace Science and Technology Group, said, this time After the outlet function of the weather gate, it will become the main outlet channel of the entire space station system.

"When the cabin was out of the cabin, the astronauts first saw the vast starry sky. This time, what they saw first was our azure planet." Fan Gaojie said.

From the blue star ball to the vast starry sky, the Chinese people walking in space are confident and calm. In the future, aerospaces will carry out more and more complicated outlet activities, and the workpieces will also become the normal work of the space station.

"Ann's home" in space is a strong stroke on the construction of a aerospace power. In October this year, the Mengtian experimental cabin will be selected. At that time, the Chinese Space Station will realize the "T -shaped" configuration, ushered in the historic moment of built.

Building a China Space Station and building a national space laboratory are an important goal of achieving the "three steps" strategy of manned aerospace project, and it is also an important symbol of building a aerospace power and a strong science and technology country. Since the 18th National Congress of the Communist Party of China, my country's aerospace industry has achieved leapfrog development, aerospace launch capabilities have improved significantly, spatial science, space technology, and space application have made a comprehensive breakthrough, and the construction of aerospace power has taken a solid step.

"Chang'e" running the moon, "Zhu Rong" to explore fire, "Beidou" refers to roads, "羲 和" every day ... Over the years, astronauts have continued to struggle. Chinese aerospace writes the next "Chinese -style romance" in space to let the world seeAt the determination of self -reliance on China's aerospace level.The fourth phase of the lunar exploration project and the major tasks of the asteroid detection have officially launched the project development, deep space detection national laboratories and other series of construction tasks have been launched, and the "three steps" of the exploration of the exploration of the day continued to make efforts ... The starry sky is vast, and the exploration is endless., China Aerospace steps are constantly.
