      Legends!Temple II to complete the historic mission will mark the moment the curtain call Forever "Temple" immortal legend at this moment, nine days of travel Temple II is a final farewell to the planet.After the orbit of the more than 1000 days to complete all the scheduled tasks, it will be Beijing on July 20 according to a controlled re-entry plan for a dazzling brilliance perfect curtain call.Many people clearly remember, in more than a year ago, Temple run more than 23 days in orbit, under the attention of millions of people, re-entry, into the dazzling bright, completed a farewell forever in the annals of.Temple and Temple II period, although actually in orbit much longer than expected, but as a spacecraft, the "service" is ultimately limited period.For the aerospace and even the history of the worlds space launches China, the Chinese "Temple" limited "service" period, we have made remarkable brilliant achievements.In the 1990s, China has developed a manned space flight "three-step" development strategy: first astronaut heaven; the second is multi-day flight, astronauts, spacecraft to achieve rendezvous and docking with the space capsule and launch short-term manned space laboratory; three is the construction of the space station, space to solve large-scale application of long-term manned.Temple and Temple II continue to struggle, join the Shenzhou series of spacecraft, to achieve a number of major technological breakthroughs include space rendezvous technology to push for the second step perfect ending "three-step" strategy for the realization of the third step That strategic objectives laid a solid foundation to build space station.Space "go-between" at 1:03 on November 2011 Ri 36 minutes and 6 seconds, vast space, two high-speed operation of the spacecraft Shenzhou VIII Temple One space rendezvous and docking to achieve a precise formation flight combination.This indicates that China has become the country after the United States, Russia, the worlds third space rendezvous and docking technology to master.The technology is a prerequisite for service on the rail assembly space station, space shuttle, space platforms and space transportation systems, recycling, supply, maintenance, and other astronauts exchanged and rescue.Hundreds of millions of people through the screen televised Beijing flight control center presented, witnessed the Chinese wisdom staged "go-between space" stunt to celebrate this exciting historic moment.Temple One mission is to provide target aircraft for the implementation of space rendezvous and docking test; the initial establishment of long-term unattended in orbit, short-term manned manned space test platform for space station development to gain experience.In addition, the temple also conducted a series of experiments in space science, aerospace medical experiments and space technology experiments.As a major sign of Chinas manned space mission development process, the historical mission of the Temple have been identified as early as in 2092.In 2002, Temple One goal of aircraft mission program through the demonstration and review, after entering the initial research stage.On the stage in mid-2009 CCTV Spring Festival Evening Year of the Ox, Temple One model brilliant appearance, its image and the mission quickly into the hundreds of millions of families, for the people we know and praise.After more than a year in time, the temple is completed final assembly, integration testing, factory evaluation and transfer.September 29, 2011, Long March II FT1 carrier rocket from the Jiuquan Satellite Launch Center sky, the Temple precision into orbit.After about a month, Shenzhou VIII spacecraft launch and space rendezvous and docking with Temple One.12 days after the assembly operation, both detached and were again successful rendezvous and docking test.2012, 2013, have ushered in the Temple of Nine and Shenzhou 10 Shenzhou, and they are the successful completion of a number of space rendezvous and docking, the spacecraft completed the combination of control and management, protection of resident astronauts in orbit, space in a series of tests to verify technical staff on-orbit servicing operation, carried out on the application of remote sensing, space physics and space environment exploration and material testing, get a lot of valuable data and application results.It is worth mentioning that the temple was Chinas first "space classroom" during the Shenzhou 10 mission, astronauts Nie Haisheng Wang Yaping in cooperation, Zhang Xiaoguang, and for space to teach over 60 million students nationwide.In about 45 minutes of "Shenzhou classroom," Wang Yaping showing the "quality measurements", "pendulum movement", "gyroscopic motion", "water film production and water polo" a number of tests, and the "world dialogue" form an interactive exchange with the kids.March 2016, Temple fully completed mission, officially terminate data services.2020 at 8:15 on April 2, the Beijing Aerospace Control Center to monitor and analyze relevant agencies, the Temple has been re-entry, re-entry drop zone located in the central area of the South Pacific, the vast majority of devices in the re-entry destroyed during ablation.Nine days on "Go" If the Temple is the "entry level" experimental aircraft space laboratory, the main goal is to complete the space rendezvous and docking mission, the Temple II is entirely a small space laboratory in the true sense, aimed at solve a certain scale, the problem of short-term manned space applications, with the conditions of work and to carry out various tests.March 2014, Zhou Jianping, chief designer of Chinas manned space program announced to the outside world that China will implement the Temple II Spacelab mission.September 10, 2014, when he was appointed deputy director of the Manned Space Engineering Office Yang Liwei into space explorers in the 27th Annual Meeting of the Association of Temple II revealed the detailed planning tasks to the outside world, including the Temple II space laboratory will launch in 2016, and to achieve space rendezvous and docking with the manned Shenzhou 11 spacecraft and the subsequent launch of cargo ship tianzhou 1, further breakthroughs and master additional propellant in orbit key technologies such as the space station to carry out a certain amount of space application.September 15, 2016, Temple II was successfully launched into orbit.October 17 over one month later, Shenzhou 11 spacecraft carrying Jing Haipeng, Chen Dong two astronauts lifted off at Jiuquan Satellite Launch Center and accurately into orbit.After several orbit, at 1:11 on October 20 into autonomous controls to guide autonomous control step by step closer to the Temple II.By the Beijing Aerospace Control Center on the docking state of readiness for final confirmation, Shenzhou 11 began to slowly move closer to the Temple II.3:24, Shenzhou 11 in contact with the butt Temple II, in accordance with the procedure after the successful completion of a series of technical operation, abutting the locking mechanism, to establish a rigid connection of two aircraft, the assembly formed.Until November 20, Shenzhou 11 unlock separated from Temple II, this mission, flying a total of 30 days the assembly, created time Chinese people residing in space a new record.Compared with the space rendezvous and docking and assembly flight Temple One Shenzhou spacecraft carried out before, this mission has been further enhanced, in addition to longer and also upgraded the optical imaging sensors and lighting equipment, improve the rendezvous and docking reliability and efficiency.In addition, a comprehensive inspection and testing of the life support system, and accumulated more experience.Propellants commonly known as "space filling" additional in-orbit space station construction is one of the core technology, and assume that technological breakthroughs falls on the shoulders of the Temple II and the cargo ship tianzhou 1.April 20, 2017, tianzhou 1 into orbit, and then through the establishment of five rendezvous and docking orbit attitude control.April 22 docking is successful, the next day 7:26, additional propellant test start, which is the Temple II carried out with the first cargo ship additional propellant, is also Chinas first propellant additional test.At 20:07 on April 27, the first in-orbit propellant to complete additional tests to achieve a "space filling" technology breakthrough.Space science experiments is an important task of the Temple II, during the orbit, Earth observation and space to carry out earth system science, space applications and test applications in the field of new technology, space technology and space medicine, etc..The worlds first space which is mounted the cold atomic clock accuracy can be increased when autonomous spacecraft keep two orders of magnitude, a substantial increase in the accuracy of navigation positioning, completed all test given task, to achieve a predetermined target error is less than 3000 years 1 second, the human time measurement accuracy in space increased 1-2 orders of magnitude.Mounted GRB polarization detector polarization detection precision finished GRB instantaneous radiation.Work together to build "days" Temple II completed its historic mission, will soon celebrate the moment the curtain call.Chinese space station assembly work preparatory work for construction projects and experiments have been carried out in full swing.According to the director of the Center for Space Applications Institute of Applied Development Center, Zhang Wei, China is expected to launch space station core module in 2020, launching JEM JEM Ⅰ and Ⅱ around 2022, after the formation of the three tanks "T" shaped configuration, constitute complete Space station.Is expected to begin operation in 2022 after the space station will, in orbit for more than 10 years.In early November 2020, the opening of the Twelfth Zhuhai Air Show, the audience excited to find that China "Heaven" space station core module 1: 1 mock impressively presented on a stand, and this is its first public meeting.Throughout the entire length of the core compartment near the station 17 m, a diameter of 4.2 meters, the future Chinese space stations command and control center.It is understood that up to six people at most "days" rated crew of three, take the time rotate the group, which will become the China National Space Laboratory long-term stable operation in orbit.The basic configuration comprises a core module, and JEM JEM Ⅰ Ⅱ, the size of each cabin 20 ton.The core node cabins cabin includes three parts, control cabin and living resources cabin, there are three pairs of interfaces and two berthing ports.Interface is used for manned spacecraft, cargo spacecraft and space station visit other aircraft parked port for two laboratory modules and assembled to form the space station core module assembly, while a spacewalk astronaut extravehicular activity statements.The axial length of the core module 16.6 meters, the large diameter section of the column 4.2 m in diameter cartridge segment 2.8 meters, mainly used for centralized control and management of the space station and the astronauts living with long-term autonomous flight capability to support long-term presence of astronauts, space medicine and support to carry out space science experiments.In terms of space station experiments, the Chinese authorities have launched a pilot project of collection activity, not only for the domestic scientific community, but also issued a warm invitation to the international community.2020 May 28, resident of the United Nations and other International Organizations in Vienna China and the United Nations Office for Outer Space Affairs in Vienna jointly organized by China International Space Station cooperation opportunities announcement ceremony officially open the China International Space Station cooperation, active around the world for his kind invitation participate, take advantage of future Chinese space station to carry out experiments outside the cabin equipped with cooperation.After the announcement, we received a total of 42 projects from 27 countries Recommendations.After two rounds of deliberation, the authorities finally identified, including space astronomy, microgravity fluid physics and combustion science, earth science, the application of new technology, space life science and biotechnology nine projects from 17 countries as the first international cooperation project.This year April 23, the eve of the fourth "China Aerospace Day", China Manned Space Engineering Office officially launched an open call for domestic-oriented space science and technology experimental pilot project activities designed to further develop the Chinese space station "Skylab National "the leading role.It is understood that the pilot project has more than a dozen research, including space life science research in animals, plants, microorganisms, cells, etc.; Fluid Science, some of the special law under microgravity fluid; carry out basic physics of ultracold atomic physics research, the understanding of the law state ultracold atoms.In addition, the use of EVA large facilities, observation of the universe, study the origin and evolution of the universe, study black holes, dark matter, etc..It is worth noting that Chinas space station to collect some science projects, according to the relevant rules, college students, high school students if there are good ideas, we can declare.For Chinese scientists interested in space science experiments, the Chinese space station will set up their unprecedented experiment platform.If space pilot projects submitted were selected, and the physical condition they pass, they can participate in the selection payload specialists, are expected to operate their experiments in space.
