Edit the source of this paragraph name.
The name "Tiangong No.1" is reminiscent of the story of "Making a scene in Heaven" in The Journey to the West, one of the four classical novels in ancient China. In addition, "Tiangong" is a popular name for the unknown space of the Chinese nation. Therefore, naming the target aircraft "Tiangong-1" should arouse a good resonance among Chinese people. This plane is actually the prototype of the space experimental station. From "Shenzhou 7" to "Shenzhou 10", it is a test of astronauts' space experiment ability and technical maturity of docking space experiment station. Then there is the third step of manned spaceflight project-to realize the establishment of a space experimental station for cooking. Manned spacecraft and cargo spacecraft will be launched alternately. The scientific name of Tiangong-1 is "Target Aircraft", because several subsequent shenzhou spaceship ships will dock with it to improve the rendezvous and docking technology of the aircraft. In the words of professionals, "Tiangong-1" is not only the target aircraft of space rendezvous and docking, but also a simple space laboratory. China will use this platform to carry out relevant technical experiments in the space laboratory.
Edit the content of this paragraph
Tiangong-1 Space Laboratory is about10.4m long, with a maximum diameter of 3.35m and a weight of 8.5t.. It adopts two-cabin structure, namely, experimental cabin and resource cabin. The experimental cabin is divided into front cone section, cylindrical section and rear cone section; The sealed front cone section and column section provide astronauts with living and working space in orbit for a short stay, which can accommodate three astronauts. The unsealed rear cone section at the rear is equipped with regenerative life support equipment; Space rendezvous and docking equipment is also installed at the front end of the front cone section. The resource module includes engine and power supply device. The solar wing is installed outside to provide orbit and attitude control, power supply, thermal control and environmental control. The Tiangong-1 target aircraft will use five folding solar panels, which is the most complicated solar wing design for China's medium-and low-orbit spacecraft.
Edit some information in this paragraph.
Tiangong-1, launched in an unmanned state, will eventually welcome "visitors" on the earth. As a place where astronauts work and live, what kind of "home" is Tiangong-1? What do you carry at home? ● Living in an artificial "earth" environment, inside the Tiangong-1 cabin.
The interior of Tiangong No.1 adopts exquisite color design, the floor is dark ochre, which has a feeling of "earth", and the cabin roof is soft gray, which avoids the stimulation of pure white on the line of sight and has a sense of lightness of "heaven". The transition color between "heaven" and "earth" is in between, and the use of different color blocks makes the hut an independent and orderly small world. If human beings want to stay in space for a long time, they must strive to create a small environment suitable for human survival. In addition to maintaining proper temperature, humidity, pressure, oxygen and other conventional environments, "Tiangong" is also equipped with special "weapons" to control microorganisms and trace harmful gases. In addition, the water vapor generated by astronauts' breathing and sweating is also automatically collected by the condensate collection device at regular intervals. [12] ● Clothing sleeping bags are embroidered with auspicious clouds. The blue astronaut sleeping bag is embroidered with auspicious clouds. Compared with Shenqi's sleeping bag, it is obviously lighter in weight and the best in material. It is flame-proof, antistatic, light in weight and adjustable in elasticity. "Tiangong" also prepared thermal underwear, warm pants, sports socks, sportswear and shorts for astronauts. The design of these clothes is special, mainly considering the special needs of space work experiments. For example, some clothes have cable openings and some pockets are used to put radiation meters. Because "Tiangong" is unmanned, long-term low-pressure operation will accelerate the aging of clothing materials. Researchers have done a lot of low-pressure storage tests on the ground and pulled clothes with professional equipment to ensure that the tensile strength and tear strength are qualified. ● There are many kinds of diet space foods. Some space foods have entered space with Tiangong-1, including vegetables, meat, fruits and rehydration soup, but these are inedible and just experiments. The truly edible space food has to wait for the astronauts to take it to the sky by spaceship. These experimental space foods will return to the ground with the docked manned spacecraft in the future. Researchers should observe what happens when they run in the sky for a long time. In the future, the types of space food that people use to fight will be very rich and more in line with the tastes of astronauts. ● Life in the leisure cabin is rich and colorful. "The life of astronauts in the cabin is not monotonous," said Zhu Yilin, a researcher at the China Academy of Space Technology and an academician of the International Academy of Astronautics. "Tiangong is equipped with physical exercise facilities and entertainment facilities for astronauts, and the audio-visual programs that astronauts are interested in are stored in the laptop in advance. Tiangong-1 brought space exercise equipment for the first time, such as a special bicycle for exercising lower limb muscles; Stretchers are used to exercise shoulder and back muscles; The lower body negative pressure cylinder exerts negative pressure on the astronaut's lower body, prompting blood to flow to the lower body, and changing the situation of blood transfer to the head in weightless environment. Passenger Chinese Knot+Seed+Flag This time, Tiangong-1 carried "three space passengers": a Chinese knot flying into space, seeds of four endangered plants and 300 flags of the International Astronautical Federation. These 300 flags were sent to the International Space Station by Russian Soyuz "TMA-20" manned spacecraft in February 20 10, and brought back to the ground by American space shuttle Endeavour in June this year.
Edit the technical features of this paragraph.
First, Tiangong-1 will complete the rendezvous and docking mission. China has adopted a three-step development strategy for manned space flight, from Shenzhou-1 to Shenzhou-6, and realized the manned spacecraft Tiangong-1.
[13] Sending astronauts to the sky safely and returning to the ground safely is the first development strategy; The second step is to solve the extravehicular activity and rendezvous and docking technology; The third step is to build a space station in China. In the second step, Shenzhou VII realized the extravehicular activity and achieved a technological breakthrough, and rendezvous and docking is the most critical and insurmountable technology to solve the construction of the space station. The construction of the future space station will be combined with multi-cabin. Rendezvous and docking technology is the most critical technology and an important technical foundation. Secondly, the Tiangong-1 target spacecraft is the first low-orbit long-life spacecraft developed and launched in China. Its characteristics are different from manned spacecraft, which is a means of transportation between heaven and earth. Tiangong-1 is mainly used for space science experiments of a certain scale, and at the same time completes the rendezvous and docking mission to provide living and working conditions for astronauts. It can be said that Tiangong-1 is also the prototype of the future space laboratory. Third, the Tiangong-1 target aircraft has adopted many new technologies. These new technologies are mainly used in space technology, and are also preliminary technical verification for the construction and test of future space stations. Finally, the Tiangong-1 target aircraft is the largest manned spacecraft developed in China at present. In this largest manned spacecraft, we have made a number of humanized designs, providing astronauts with 15 cubic meters of working and living space, and equipped with exercise and entertainment facilities. Astronauts can realize videophone communication with the ground and engage in personal entertainment activities.
Edit the four tasks in this paragraph.
First, the Tiangong-1 target aircraft, as the rendezvous and docking target, cooperates with the spacecraft to complete the space rendezvous and docking mission. Second, realize the control and management of the assembly after the spacecraft docked with the Tiangong-1 target aircraft. After the rendezvous and docking of Shenzhou-8 and Tiangong-1 in the air, the two aircrafts will be integrated into one, and Tiangong-1 will undertake the overall control and management of energy, information, thermal environment, attitude and orbit control. Third, realize the astronauts' stay, life and work in orbit, and provide basic conditions for astronauts to work and live in the assembly. Fourth, carry out space technology experiments to carry out early technical verification for future space station construction.
Edit this launch mission
The launch of Shenzhou VII inspired the whole country. After the Shenzhou VII spacewalk, the space station in China is getting closer and closer to us. According to China Manned Space Engineering Network, the name of China Future Space Station is called "Tiangong". This is a name with China characteristics, which has placed infinite hopes on Chinese people. According to the plan, China launched Tiangong-1 on 20 1 1. "Tiangong-1" is actually an experimental version of the space laboratory, which adopts a two-cabin configuration, namely an experimental cabin and a resource cabin. After that, "Shenzhou VIII" will be launched. "Shenzhou VIII" is an unmanned shenzhou spaceship, and an unmanned automatic docking test was conducted with "Tiangong No.1". Before 20 15, Tiangong-2 and Tiangong-3 were launched one after another. Tiangong-2 will mainly carry out applications and experiments in the fields of earth observation, space earth system science, new space application technology, space technology and space medicine. "Tiangong-3" will mainly complete experiments to verify the key technologies of regenerative life support, the mid-term in-orbit stay of astronauts and the in-orbit test of cargo spacecraft. Some experiments in space science and space medicine will also be carried out. At present, the space laboratory being developed in China adopts a two-cabin structure, namely, an experimental cabin and a resource cabin. The experimental cabin can ensure the living conditions of astronauts such as pressure, temperature and humidity, gas composition and so on. It can be used for astronauts' working and living in orbit during their stay, and the sealed rear cone section is equipped with regenerative life support equipment. The docking mechanism and rendezvous and docking measurement and communication equipment are installed at the front end of the experimental module to support rendezvous and docking with the spacecraft. The resource module provides power for orbital maneuver and energy for flight. The key technology of building a space station is "space rendezvous and docking". The process of two or more spacecraft reaching the same position in space at the same time through the coordination of orbital parameters is called rendezvous. Docking is to connect two spacecraft into a whole through a special docking mechanism on the basis of rendezvous. The system to realize rendezvous and docking of two spacecraft in space is called rendezvous and docking system. Space rendezvous and docking technology is very difficult, because the space laboratory is relatively large, and no people are installed when launching the space laboratory. Later, people were sent into space by the space shuttle or spacecraft. If people want to enter the space laboratory, the space shuttle or spacecraft must dock with the space laboratory. This is very difficult. Both the space laboratory and the space shuttle are running at high speed, with a speed of over 28,000 kilometers per hour. In the process of docking, if the calculation is inaccurate, a collision accident may occur. Tiangong-1 simulation docking effect map
[14] There are two control modes for space rendezvous and docking, one is manual control, and the other is automatic control. Using manual control to complete space rendezvous and docking can improve the success rate of rendezvous and docking. The reliability of automatic control rendezvous and docking is particularly high, and there is no need to consider the safety and life-saving of personnel. In the rendezvous and docking technology of spacecraft, the future development trend is to combine manual control with automatic control to improve the flexibility, reliability and success rate of rendezvous and docking. At present, the maximum carrying capacity of rockets in China is only 10 ton, which can not only launch larger and heavier space laboratories, but also meet the transportation requirements of a large number of materials needed in the operation of space laboratories. In the subsequent launch, a new generation of high-thrust Long March 5 rocket will be used. The carrying capacity of the Long March 5 rocket can reach 25 tons, which is basically equivalent to the international top level and can meet the needs of the low-orbit launch space laboratory. At present, the ultimate goal of human manned space activities is to move the laboratory into space, and use the unique microgravity and high vacuum environment in space to carry out life science and material science experiments that cannot be carried out on the ground for the benefit of mankind. Space life science experiments can not only carry out plant breeding and invent new drugs, but also have different benefits in semiconductors, special materials, astronomy, earth observation and so on. Therefore, the construction of the space station from Shenzhou VII will bring a bigger stage for scientific research. [ 15]

Docking introduction
"Space rendezvous and docking", referred to as "rendezvous and docking", is the most basic and key technology to build a space station. Its principle is to make two or more spacecraft reach the same position in space at the same time through the coordination of orbital parameters, and then connect them into a whole through a special docking mechanism. Rendezvous and docking can be divided into manual control, remote control and autonomy according to the intervention degree and intelligent control level of astronauts. Generally speaking, the specific method is to launch the target aircraft into orbit and accurately determine its orbit. When it flies over the launch site of the aircraft to be launched, the latter will run in the same orbit with the former by choosing the launch opportunity, and the distance will be controlled within a certain range, and then the two will gradually connect by the maneuverability of the aircraft itself.
Docking process
Tiangong-1 renderings
During the Shenzhou-8, Shenzhou-9 and Shenzhou-10 missions, China will break through the docking technology between unmanned and manned spacecraft and build the first space laboratory, named Tiangong-1. This was revealed by Zhang Jianqi, deputy commander-in-chief of manned spaceflight project and deputy commander-in-chief of Shenzhou VII mission command, in an exclusive interview with China Manned Space Engineering Network. After Tiangong-1, Shenzhou-8, Shenzhou-9 and Shenzhou-10 will be launched to dock with it. Regarding the type of docking, Zhang Jianqi said that "Shenzhou-8" is definitely unmanned, and whether someone docks "Shenzhou-9" or "Shenzhou-10" mainly depends on whether the rendezvous and docking of "Shenzhou-8" is smooth. Only after three successful docking can the second strategic goal be fully realized. The success of "rendezvous and docking" is undoubtedly the key to achieving strategic goals and is recognized as the bottleneck of space technology. In the early days of manned space activities abroad, the spacecraft failed in the process of rendezvous and docking in space. For example, the Russian "Progress M3-4" spacecraft collided with the "Peace" space station during docking. Regarding the technical strength of rendezvous and docking in China, Qi Faren, the former chief designer of shenzhou spaceship, said that the Shenzhou series spacecraft had made many technical improvements since Shenzhou VIII and became a brand-new space shuttle. Among them, the rendezvous and docking function is its main feature, and astronauts can control the spacecraft according to TV images to keep it close to the target aircraft.
Astronaut selection
Regarding when women can join China astronauts, Wang Zhaoyao, spokesman of China Manned Space Engineering and deputy director of China Manned Space Engineering Office, said at the press conference of the State Council Office held on September 27th, 2008 that there is no timetable for selecting female astronauts in China at present, but related topics are being studied. Shanguang Chen, the chief commander and chief designer of the astronaut system of manned spaceflight project, recently revealed that the preparation for the selection of a new generation of astronauts in China has been completed, and it is expected that the selection will be officially launched after the Shenzhou VII mission. The new generation of astronauts is still planned to be selected from the air force pilots, and the number will not exceed the first batch 14. Cosmic laboratory

Complete the final assembly
20 10 08 17, a spokesman for China's manned spaceflight project, said that Tiangong-1 Shenzhou-8, the first space rendezvous and docking target of China's manned spaceflight project, will be launched this year.
Gong-1 target aircraft has recently completed the final assembly and has been fully transferred to the stage of comprehensive electrical performance testing. After completing a series of electrical, mechanical and thermal performance tests, the spacecraft will be launched into the predetermined orbit on 20 1 1, and then the Shenzhou-8 spacecraft will be launched to rendezvous and dock with it. The spokesman said that since the end of 2009, the main flight products such as Tiangong-1 target aircraft, improved Long March-2 F launch vehicle and improved Shenzhou manned spacecraft, which have carried out rendezvous and docking missions, have successively completed various development and test work in the initial stage and have been fully transferred to the prototype development stage. At present, the preparations for the rendezvous and docking mission are progressing smoothly. Shenzhou-8 spacecraft is undergoing final assembly; The improved Long March II F rocket product has been completed and the subsystem comprehensive test is being carried out. The training of rendezvous and docking astronauts is in full swing, and the second batch of astronauts in China, including two female astronauts, also participated in the training; All kinds of space science experimental load equipment loaded by Tiangong-1 target aircraft and Shenzhou-8 spacecraft were delivered to the final assembly of the aircraft as planned, and all preparations for the ground support system were comprehensively promoted. According to the plan, China will launch Tiangong-1 and Shenzhou-8 spacecraft in 20 1 1 year to carry out the first unmanned rendezvous and docking test of spacecraft. [ 16]
Complete the system performance experiment.
According to the Voice of China "Chaoguang News" reported on March 4, the news from the Space Technology Research Institute of China Aerospace Science and Technology Corporation said that "Tiangong No.1" is already Tiangong No.1.
After the performance experiments of each system are completed, the interface matching between systems and the development of various space science experimental equipment for simulated flight tests are progressing smoothly. [17] Tiangong-1, which has completed the final assembly work, has now revealed its true colors. The size of Tiangong-1 is still much larger than that of shenzhou spaceship, and the first half is its experimental cabin. Astronauts and scientists will mainly focus on experiments in the first half of the year. Staff of Space Technology Research Institute of China Aerospace Science and Technology Corporation: At present, Tiangong-1 has completed the final assembly work, which means that our entire aircraft and system can basically run. The comprehensive test is mainly to power on Tiangong-1. The researchers will simulate various real working modes in the sky and carry out experiments at Tiangong-1 Tiangong-1 base.
According to the plan, China will launch Tiangong-1 target aircraft and Shenzhou-8 spacecraft this year, and carry out the first unmanned rendezvous and docking experiment of spacecraft.
Service life limit
Zhang Jianqi, former deputy commander-in-chief of China's manned spaceflight project, revealed in an interview that Tiangong-1 weighs 8 tons, adopts brand-new design and many new technologies, and has a service life of two years. He further introduced that China's manned spaceflight project is divided into three steps: first, astronauts go to heaven; Second, many people fly for many days, astronauts leave the cabin, realize the rendezvous and docking of the spacecraft and the space capsule, and launch a short-term manned space laboratory; The third is to establish a permanent space station. This launch is to complete the follow-up task of the second step and lay the foundation for completing the strategic goal of the third step. Tiangong-1, which will be launched soon, is the prototype of the first space laboratory in China. It weighs 8 tons and has a design life of 2 years.
Edit the rocket status quo in this paragraph.
Every progress in China's manned space flight means that a large number of technological breakthroughs must be completed. For example, from the first manned space flight in Shenzhou 5 to the spacewalk of Shenzhou VII astronauts, the spacecraft has made more than 200 improvements. So is the launch of Tiangong-1. It is reported that Jiuquan Satellite Launch Center conducted a comprehensive inspection and quality evaluation of the facilities and equipment of the manned space launch site, and completed 66 upgrades of the survey and launch command and monitoring system. The Long March II F carrier rocket was mainly developed by China Academy of Launch Vehicle Technology. In order to meet the requirements of rendezvous and docking, relevant experts have made nearly 170 technical status changes. The maximum carrying capacity of rockets in China is only 10 ton, which can not only launch larger and heavier space laboratories, but also meet the transportation requirements of a large number of materials needed in the operation of space laboratories. In the subsequent launch, a new generation of high-thrust Long March 5 rocket will be used. The carrying capacity of the Long March 5 rocket can reach 25 tons, which is basically equivalent to the international top level and can meet the needs of the low-orbit launch space laboratory. The ultimate goal of human manned space activities is to move the laboratory into space, and use the unique microgravity and high vacuum environment in space to carry out life science and material science experiments that cannot be carried out on the ground for the benefit of mankind.

Edit the publication time of this paragraph.
The spokesman for China's manned spaceflight project 2011announced on September 20th that Tiangong-1 will be launched in Jiuquan from September 27th to 30th (the current launch time is set at 9: 00pm on September 29th16th). The combination of Tiangong-1 target aircraft and Long March-2 F carrier rocket has been transported to the launch area. [1 9] On September1day, a spokesman for China's manned spaceflight project said that the mission headquarters decided to make corresponding adjustments to the launch plan of Tiangong-1 due to the failure of the launch of Chang 'e-4 satellite No.11. The spokesman said that the main consideration in adjusting the launch plan is that the Long March II F carrier rocket and the failed Long March II C rocket belong to the same series. As the accident investigation and handling of the faulty rocket are still in progress, it is not clear whether the cause of the failure is related to the Long March II F carrier rocket. It is reported that at present, each system of the project is conducting a comprehensive quality review of all flight products that perform the first rendezvous and docking mission. The specific launch time of Tiangong-1 will be determined according to the fault investigation results of the faulty rocket.
The spokesman said that according to the plan, the first rendezvous and docking mission will first launch the Tiangong-1 target aircraft, and then launch the Shenzhou-8 spacecraft to carry out the unmanned automatic rendezvous and docking test. The main task of Tiangong-1 flight is to provide rendezvous and docking targets for spacecraft rendezvous and docking flight test, break through and master rendezvous and docking technology, initially establish a manned space test platform with long-term unmanned operation and short-term care, accumulate experience for space station development, and carry out space science experiments, space medical experiments and space technology experiments. According to reports, flight products such as Tiangong-1 target aircraft and Long March II F carrier rocket have been put into the market since the end of June, and preparations for technical fields such as final assembly test have been carried out in accordance with the flight mission test and launch process. The Long March II F carrier rocket also took corresponding improvement measures for the failure cause of the "Practice 11 04 Star" rocket. After the propellant filling, Tiangong-1 was hoisted and docked with the launch vehicle to form a complete assembly. At 9: 00 on the 20th, the mobile launch platform carrying the assembly drove out of the vertical assembly test workshop of the manned space launch site and arrived safely at the launch tower. In the next few days, the launch site will conduct functional tests of the target aircraft and rockets, as well as joint tests of the aircraft and rockets. After the final state inspection is confirmed, the rocket will be filled with propellant and launched at an appropriate time.
