　　 Reporter Hao Jie ?

　　 At 9:22 a.m. on the 17th, the long march-2 f-remote-12 carrier rocket carrying shenzhou-12 manned spacecraft ignited and launched on time at Jiuquan Satellite Launch Center. Shenzhou-12 manned spacecraft successfully separated from the rocket and entered the scheduled orbit. Three astronauts, Nie Haisheng, Liu Boming and Tang Hongbo, were successfully launched into space. The launch was successful.

　　 After entering space, the spacecraft will rendezvous and dock with the core module of the space station which is already in space. The astronauts will be stationed in the core module of the space station. In the future, they will work and live in orbit for three months, during which they will also work outside the capsule.

　　 In the future, astronauts can complete the repair and maintenance of space station spacecraft and equipment replacement under the condition of operating the manipulator, which puts forward higher requirements for the design and manufacture of extravehicular spacesuits they wear.

　　 A variety of functions of the new generation spacesuit have been upgraded

　　 According to relevant reports, China's astronauts have been equipped with a new generation of space suits, and various functions have been upgraded. The extravehicular spacesuit, which is used to carry out the extravehicular mission, has been improved in structural layout design, clothing life and ergonomics, so as to ensure that astronauts can carry out a series of complex operation and related load tests of space station in absolute safety environment. ?

　　 Nie Haisheng, a special class astronaut of the Chinese people's Liberation Army astronaut brigade, said that the biggest change in the spacesuit is the increase in the support time for spacesuits. In the past four hours or so, this time it can stay for 7-8 hours; The second is that the joints have been changed, and the range of motion is better. Then there are some other electronic devices, including cameras, which may be more helpful for the task. ?

　　 Liu Boming, a special class astronaut of the Chinese people's Liberation Army astronaut brigade, said that some corresponding adjustments have been made to the clothing this time, and some materials have been replaced, making it more comfortable to wear. It was very difficult to grasp the safety hook when crawling outside the cabin, because most of the physical strength was spent on it. This time, I think it will save time and effort than before. Therefore, compared with the improvement of Shenzhou 7, we feel that the comfort level is higher. ?

　　 Extravehicular spacesuit is a kind of equipment that astronauts wear when carrying out space missions. Although it is a suit of clothing, it has various life support and support functions similar to the space station. The extravehicular space suit concentrates the life maintenance and support functions of manned spacecraft into this suit of clothing, for example, it has the functions of radiation protection, high and low temperature protection, oxygen supply and heat preservation, pressure adjustment, etc, In short, it is a set of life support system that people can survive in outer space for a period of time, or it is a small manned spacecraft.

　　 The EVA spacesuit has six layers inside and outside, which can withstand the test of temperature difference of more than 200 degrees Celsius in outer space. Its production cost is as high as tens of millions of yuan. However, it is waterproof, fireproof, gas and radiation proof. It can be said that it is "seamless". If people wear it on, it can be said that there are two worlds inside and outside the clothing.

　　 It is understood that the biggest highlight of this mission is undoubtedly the astronauts' extravehicular activities, which will be 13 years after Shenzhou 7 in 2008. Moreover, the scale and complexity of this spacewalk will be beyond the reach of Shenzhou 7.

　　 At that time, with the support of the core module manipulator, Chinese astronauts will wear a new generation of spacesuits and carry out two times of extravehicular operations, including the installation of the extravehicular toolbox, the lifting of panoramic camera, the installation of expansion pump units and personnel transfer, etc., and the time for getting out of the cabin will be as long as 6 or 7 hours. ?

　　 All the working and living clothes of astronauts come from Donghua University

　　 In addition to the spacesuit, the series of special clothes for astronauts in the whole process of space and ground work and life are also important aspects to ensure the astronauts can fly smoothly. These clothes, as well as the shoes for astronauts in the space station mission, all come from the innovation and hard work of the research and design team of Donghua University for many years. ?

　　 These clothes include not only the working clothes, exercise clothes, leisure clothes, weightlessness protective clothing and sleeping gear for astronauts working and living in the space station, but also many kinds of ground mission clothing such as regular clothes, task training clothes and special clothes. These special clothes should not only ensure the realization of many special functions, but also integrate the design elements with Chinese characteristics, Become the "space Costume" for astronauts to appear in the world.

　　 "Chinese astronaut's special clothing is a multi-functional garment with functional and ergonomic priority, which has aesthetic quality. The astronaut clothing R & D and design team of Donghua University has integrated the era elements with Chinese characteristics in the surface accessories, color patterns, and even the sewing trace of clothing details, showing the beautiful image of Chinese astronauts as space dreamers and guardians of the Chinese dream." Donghua University astronaut clothing R & D team leader, fashion and art design school dean Li Jun said.

　　 The styles, colors, patterns and textures of the full series of spacesuits and accessories should not only match each other, but also be compatible with the cabin environment. They should not only reflect the cultural elements with Chinese characteristics and the characteristics of the times, but also reflect the professional characteristics and spiritual outlook of the astronauts. Different types of clothing with different functions can help astronauts fight against the adverse effects of weightlessness on human muscles during long-term space flight, and some can also protect astronauts to adjust their emotions and moods. At the same time, the display effect of photography, photography and image transmission in the cabin light environment should be considered. It can be said that "the same dish must satisfy hundreds of stomachs". ?

　　 For example, in the design of astronaut's regular clothes, the elements symbolizing the earth's skyline and outer space color are added on the basis of the sky color of lake blue, so that the clothing looks more three-dimensional and full and more layered. Most of them are three-dimensional straight lines. The "s" shaped arc of the front shoulder metaphors the space flight track and the V-shaped straight line of the front chest symbolizing victory, presenting the beauty of thick, thin, straight and harmonious. ?

　　 In addition to the clothing itself, the design of some clothing articles worn by astronauts should be systematically planned according to the color and shape of clothing. Among them, the main line of the astronaut honor logo is like the trajectory of a spacecraft flying in the blue universe, which gives people a sense of upward flight. The number of five pointed stars indicates the number of times the wearer performs manned missions. Through the comprehensive carrier of astronaut special clothing, the team shows the connotation and style of "flying sky" with artistic design. ?

　　 Tianhe core module is the "space home" for astronauts. It provides three times as much space for astronauts as the tiangong-2 space laboratory. It is equipped with three independent bedrooms and a toilet to ensure the astronauts' daily life for up to three months. Living in the "big house" for a long time, of course, is inseparable from a pair of comfortable and beautiful "home shoes" (shoes used in the astronaut space station mission module).

　　 "The shoes used in the astronaut cabin should be" flexible "to protect the safety and comfort of the feet, as well as the fashionable design and heavy culture." According to Zheng Rong, head of the research and design team of the astronaut cabin shoes of Donghua University and professor of the international fashion science and innovation center of Donghua University, the design and development of cabin shoes integrates the school's advantages in many fields, such as anthropometry, ergonomics, materials, 3D modeling, rapid prototyping and product design, And obtained the support of industry resources and related cooperative enterprises and units. The relevant advanced technologies and achievements based on ergonomics are applied to the greatest extent, and the three-dimensional foot scanning technology, plantar pressure analysis, integrated weaving and other technologies are combined, and the design influencing factors including the special environment of the space station, the characteristics of human body, and the demand of sports are carefully and comprehensively considered.

　　 The shoes used in the cabin are mainly made of thermoplastic materials and blended knitted materials. They are soft, light, environmentally friendly, antistatic, breathable and elastic, which ensure the comfort and safety of the astronauts' feet when they are carrying out activities in the weightlessness environment of the spacecraft cabin and the space station. At the same time, the cross size design is adopted for the cabin shoes. The size system can cover multiple male and female astronauts, and the foot morphological changes under various working environments are considered to match the foot movement characteristics of astronauts. Considering the microgravity state and the weight requirements of the spacecraft, the shoes used in the cabin are much lighter than ordinary shoes worn by ordinary people.

　　 The wave like structure of "fish ribs" is tried in the foot modeling, which ensures the unity of flexibility and protection, so as to cushion the collision caused by astronauts' movement. The front and back of feet are full in design, which not only makes the wearing more comfortable, but also makes the shape more three-dimensional. The final color is the combination of "deep blue" and black color. Black reflects the factors of fashion and technology. At the same time, it matches with the blue of cabin work clothes to realize the harmonious sense of visual collocation. ?

　　 The highlight of the cabin shoes lies in the sole. On the basis of ensuring the functionality, the hollowed out design of the sole originates from the artistic design changes of seal script and Chinese characters. The "stars" surrounded by the outer ring not only show Lingyun's great ambition of "daring to explore the moon in the nine days and catch turtles in the five seas", but also the Chinese style romance and feelings are on the paper.
