    Goodbye Tiangong-2

    http://www.xinhuanet.com/english/201..._138241415.htm

    China's space lab Tiangong-2 reentered the earth's atmosphere under control at around 9:06 p.m. on Friday (Beijing time), China Manned Space Agency (CMSA) said.

    A small amount of the spacecraft's debris fell into the predetermined safe sea area in the South Pacific, according to the agency.

    Tiangong-2's controlled reentry into the atmosphere marks the successful completion of all the tasks in the space lab phase in China's manned space program, said Zhou Jianping, chief designer of China's manned space program.

    Can weightlessness stop cancer from growing? One of the nine research projects that has been given the go-ahead for the new China Space Station scheduled for 2022 is designed to answer this exact question.

    The unique laboratory conditions offered by the International Space Station and the to-be-launched China Space Station (CSS) allow for research on everything from ultrasound diagnostics in microgravity to studies of crystal growth.

    Now, when the China Space Station is ready to begin research projects around 2022, it will include an unusual cancer research project called “Tumours in Space,” headed by a Canadian researcher based in Norway. The project will examine the roles of both microgravity and cosmic radiation in tumour growth and development.

    "China Space Station – is it worth it?"

    https://westeastspace.com/2020/03/30...s-it-worth-it/

    Based on the experience of the USSR and China, the main reasons why space leaders and countries that claim to become ones invest huge amounts of money in the construction of space stations can be identified. Once again, let us list and prioritize them:

    Military advantage is a practice-oriented goal, which is aimed at ensuring national security. As a rule, it serves as an impetus to start developing manned programs.
    Prestige and political influence is an important goal, its effect is quite obvious, although it is hard to estimate in quantitative terms. It allows politicians to gain the support of the population and strengthen the position of the state on the world arena.
    Progress in science and technology is a long-term goal that allows significant breakthroughs in many fields of science, from basic physics and astronomy to medicine and information technology. Very often, technological developments that were initially applied in a space station are later applied in other fields.
    The platform for international cooperation is an even more long-term goal, which allows for more effective implementation of the state’s foreign policy. To achieve this goal, a more advanced level of development of manned programs is required, at a minimum, the existence of its own multi-module station.

    The biggest reason for China to develop anything in space is today economic. The rest of the stuff the author states is mostly nonsense from a few decades ago.

    "China outlines intense space station launch schedule, new astronaut selection"

    https://spacenews.com/china-outlines...aut-selection/

    China is preparing to carry out 11 missions in two years to construct a space station and will soon select a new batch of astronauts for the project.

    The first module for the Chinese space station will launch next year, said Zhou Jianping, chief designer of China’s human spaceflight program, on the sidelines of a political conference in Beijing Tuesday.

    Launch of the Tianhe core module on a Long March 5B could take place at Wenchang in early 2021. This will be followed by a crewed Shenzhou flight, from Jiuquan, and a Tianzhou cargo mission. The first of two experiment modules will then launch for docking with Tianhe.

    In total 11 launches will be conducted to complete the construction of the space station by around 2023, Zhou said (Chinese). These will be the launch of the core and two experiment modules, as well as four crewed spacecraft and four cargo spacecraft.

    The intensive launch plan was revealed following the successful test flight of the Long March 5B heavy-lift rocket May 5. The missions will be conducted using Long March 5B, Long March 2F and Long March 7 launch vehicles.

    I admit I don't pursue the details but the Chinese space endeavours seem so opaque to me. So this catches me by surprise. Hopefully there'll be more media coverage as the human program progresses.

    11 missions in 2 years seems quite ambitious. There've been a number of launch failures recently. Is this is a reflection of serious problems or just bad luck? Regardless, I hope it is all successful.

    This is good news for all space exploration fans.

    Two of the failures were with new rockets. Delay with their Space station was due to the initial problems they had with their LM-5. They have overcome those problems, and used the LM-5 to send their Mars probe. Next month the Chang'e-5 mission will also use the LM-5.

    "Core module of China's first space station to be launched in 2021"

    http://www.chinadaily.com.cn/a/20201...d0ba9e948.html

    China will launch the core module of the country's first space station in the first half of next year, Zhou Jianping, chief designer of China's manned space project, said on Friday.

    The space station is expected to be finished around 2022. All testing work of its core module has been completed and the Long March 5B rocket, a heavy-lift launch vehicle which carried out its successful maiden flight in May, is also in its final stage of testing, he said.

    After the core module enters into the orbit, China will launch the cargo spacecraft Tianzhou-2 and manned spacecraft Shenzhou-12 and the astronaut crew will stay in space for several months before the launch of Tianzhou-3 and Shenzhou-13 which will send the second crew into the space, Zhou added.

    "During this period, we will carry out comprehensive verification of the new technologies of the space station, including astronauts' spacewalk, robotic arms and energy technologies," he said.

    We can see progress in the preparation for the 1st launch of the LM-5B. They carried out the 4th reliability test run for its high-thrust oxyhydrogen engine.

    https://news.cgtn.com/news/2021-01-0...VOw/index.html

    China completed a reliability test run for its high-thrust oxyhydrogen engine designed for the Long March-5B carrier rocket on Friday, a critical step in the preparation for the subsequent space missions.

    The Long March-5B carrier rocket will be used for launches of different modules of China's space station as the core module is scheduled to launch this spring.

    The engine ran 500 seconds during the test – the same amount of time of its designed full work cycle. It is the fourth time the engine has been tested with 500 seconds, showing great ability of extending service life, one of the goals of the test.

    Here is an article from 2019 on nine international scientific projects to be conducted on the space station. It is being coordinated through the offices of the United Nations Office for Outer Space Affairs (UNOOSA).

    https://www.chinadaily.com.cn/a/2019...577230d2c.html

    China Space Station is set to welcome aboard nine international scientific projects from 17 countries covering a wide range of research areas.

    They include space life sciences and biotechnology, microgravity physics and astronomy, the China Manned Space Agency and the United Nations Office for Outer Space Affairs announced on Wednesday in Vienna, Austria.

    It is the first time a Chinese space mission has invited all members of the UN to conduct experiments, and is a milestone in the advancement of China's manned space program from independent development to global cooperation, said Lin Xiqiang, the agency's deputy director.

    The agency's head, Hao Chun, said at the event that China will be "delighted" to see scientists from different countries, nationalities and cultural backgrounds conducting space experiments on China Space Station.

    "The purpose of China's manned space program is to benefit all mankind by peacefully using outer space, which is also in line with UNOOSA's values. China Manned Space Agency is willing to adhere to the principles of equality, mutual benefits and common development and continue the exchanges with other countries and regions in the world that are also committed to this purpose," Hao said.

    China and project applicants will sign cooperation agreements by the end of 2019, and the station is expected to be put into use around 2022. The agency will continue to work closely with UNOOSA and open a second round of applications in a timely manner.

    More details of the Chinese Space Station, including launching of the various components and astronauts.

    https://www.nasaspaceflight.com/2021...plete-by-2022/

    Starting in 2021, the construction of the Tiangong orbital space station is expected to be complete in 2022 after eleven missions, including three launches of different modules, four launches of cargo vehicles and four crewed launches.

    This step comes after a phased approach to human spaceflight development, beginning with the uncrewed test flights of a crewed space vehicle (Shenzhou-1 to Shenzhou-4). This was followed by the launch of a crewed mission (Shenzhou-5 with one taikonaut), the launch of a space crew (Shenzhou-6 with two taikonauts and Shenzhou-7 with three taikonauts), and the execution of an extravehicular activity (Shenzhou-7).

    China also achieved the launch of a Salyut-1 type space module (Tiangong-1 and Tiangong-2), the development of rendezvous and docking (Shenzhou-8), space module occupation and long duration flight (Shenzhou-9 and Shenzhou-10), and the launch of a cargo freighter (Tianzhou-1) for the regular resupply of orbital stations.

    In just a few years, and following a properly phased program, China moved from short term crewed space flight to the construction of a modular space station that will allow six-month stays in Earth orbit, thus reaching a similar capability to the International Space Station program, which includes major contributions from the United States, Russia, Japan, Europe, Canada, and others, but not China.
