Tiangong (Chinese: 天宫; pinyin: Tiāngōng; lit. 'Palace in the Sky'),[5][6] officially the Tiangong space station (Chinese: 天宫空间站), is a space station being constructed by China in low Earth orbit between 340 and 450 km (210 and 280 mi) above the surface. Being China's first long-term space station, it is the goal of the "Third Step" of the China Manned Space Program. Once completed, the Tiangong Space Station will have a mass between 80 and 100 t (180,000 and 220,000 lb), roughly one-fifth the mass of the International Space Station and about the size of the decommissioned Russian Mir space station.

The construction of the station is based on the experience gained from its precursors, Tiangong-1 and Tiangong-2.[7][8][9] The first module, the Tianhe ("Harmony of the Heavens") core module, was launched on 29 April 2021,[5][6] followed by multiple crewed and uncrewed missions and two more modules to be launched by 2022.[7] Chinese leaders hope that research conducted on the station will improve researchers' ability to conduct science experiments in space, beyond the duration offered by China's existing space laboratories.[10]

Nomenclature

Deng Xiaoping decided[citation needed] that the names used in the space program, previously all chosen from the revolutionary history of the PRC, would be replaced with mystical-religious ones. Thus, the new Long March launch vehicles were renamed Divine arrow (神箭),[11][12] space capsule Divine vessel (神舟),[13] space shuttle Divine dragon (神龙),[14] land-based high-power laser Divine light (神光)[15] and supercomputer Divine might (神威).[16]

These poetic[17] names continue as the first, second, third, fourth and fifth Chinese Lunar probes are called Chang'e after the Moon goddess. The name "Tiangong" means "heavenly palace". Across the PRC the launch of Tiangong 1 inspired a variety of feelings, including love poetry. Within the PRC, the rendezvous of space vehicles is compared to the reunion of the cowherd and the weavergirl.[18]

Wang Wenbao, director of the China Manned Space Agency (CMSA), told a news conference in 2011 "Considering past achievements and the bright future, we feel the manned space programme should have a more vivid symbol, and that the future space station should carry a resounding and encouraging name. We now feel that the public should be involved in the names and symbols, as this major project will enhance national prestige and strengthen the national sense of cohesion and pride".[17][19][20] Imagery of the Chinese space program has been used by the Party (government) to strengthen its position and promote patriotism since the late 1950s and early 1960s.[21]

On 31 October 2013, CMSA announced the new names for the whole program:[8]

Purpose and mission

According to China Manned Space Agency (CMSA), which operates the space station, the purpose and mission of Tiangong space station is listed as: Further development of spacecraft rendezvous technology; Breakthrough in key technologies such as permanent human operations in orbit, long-term autonomous spaceflight of the space station, regenerative life support technology, and autonomous cargo and fuel supply technology; Test of next-generation orbit transportation vehicles; Scientific and practical applications at large-scale in orbit; Development of technology that can aid future deep space exploration.[28][29][30]

Operations will be controlled from the Beijing Aerospace Flight Control Center in China. To guarantee the safety of astronauts on board, a Long March 2F with a Shenzhou spacecraft will always be on standby for an emergency rescue mission.[31]

Structure

"T" concept of the Chinese large modular space station

The space station will be a third generation modular space station. First generation space stations, such as early Salyut, Almaz, and Skylab, were single piece stations and not designed for resupply. Second generation Salyut 6 and 7, and Tiangong 1 and 2 stations, are designed for mid-mission resupply. Third generation stations, such as Mir and the International Space Station, are modular space stations, assembled on-orbit from pieces launched separately. Modularised design methods can greatly improve reliability, reduce costs, shorten development cycle, and meet diversified task requirements.[7]

Modules

The initial target configuration for the end of 2022 consists of three modules, which may be expanded to six in the future.[32]

The Tianhe Core Cabin Module (CCM) provides life support and living quarters for three crew members, and provides guidance, navigation, and orientation control for the station. The module also provides the station's power, propulsion, and life support systems. The module consists of three sections: living quarters, service section and a docking hub. The living quarters will contain a kitchen and toilet, fire control equipment, atmospheric processing and control equipment, computers, scientific apparatus, communications equipment to send and receive communications via ground control in Beijing, and other equipment. An ISS Canadian-style SSRMS robotic arm was folded under the Tisane service section. Additionally, the Wentian experiment (described below) will carry a duplicate stowed second SSRMS robotic arm. In 2018 fullscale mockup of CCM was publicly presented at China International Aviation & Aerospace Exhibition in Zhuhai. The video from CNSA revealed that two of these core modules have been built. Artist impressions have also depicted the two core modules docked together to enlarge the overall station.

The first of two Laboratory Cabin Modules, 'Wentian' and 'Mengtian' respectively, will provide additional navigation avionics, propulsion and orientation control as backup functions for the CCM. Both LCMs will provide a pressurised environment for researchers to conduct science experiments in freefall or microgravity which could not be conducted on Earth for more than a few minutes. Experiments can also be placed on the outside of the modules for exposure to the space environment, cosmic rays, vacuum, and solar winds.

Like Mir and the Russian orbital segment of the ISS, the Tiangong modules will be carried fully assembled into orbit, in contrast to the US Orbital Segment of the ISS, which required spacewalking to interconnect cables, piping, and structural elements manually. The axial port of the LCMs will be fitted with rendezvous equipment and will first dock to the axial port of the CCM. A mechanical arm similar to the Russian Lyappa arm used on the Mir space station will then move the module to a radial port of the CCM.[33] In addition to the Lyappa arm used for docking relocation, a 10-meters long robotic arm for exterior station operations is also mounted on the Tianhe module.[34]

Systems

Power supply

Electrical power is provided by two steerable solar power arrays on each module, which use gallium arsenide photovoltaic cells to convert sunlight into electricity. Energy is stored to power the station when it passes into the Earth's shadow. Resupply spacecraft will replenish fuel for the station's propulsion engines for station keeping, to counter the effects of atmospheric drag. The solar arrays are designed to last up to 15 years.[38]

Docking

Tiangong is fitted with Chinese Docking Mechanism used by Shenzhou spacecraft and previous Tiangong prototypes. The Chinese docking mechanism is based on the Russian APAS-89/APAS-95 system. Despite NASA describing it as a "clone" to APAS,[39] there have been contradictory claims on the compatibility of the Chinese system with both current and future docking mechanisms on the ISS, which are also based on APAS.[40][41][42] It has a circular transfer passage that has a diameter of 800 mm (31 in).[43][44] The androgynous variant has a mass of 310 kg and the non-androgynous variant has a mass of 200 kg.[45]

Chinese Docking Mechanism was used for the first time on Shenzhou 8 and Tiangong 1 space station and will be used on future Chinese space stations and with future Chinese cargo resupply vehicles.[46][40]

Propulsion

Tiangong space station is fitted with conventional chemical propulsion and ion thrusters to adjust and maintain the station's orbit. Four Hall-effect thrusters are mounted on the hull of Tianhe core module.[47] The development of the Hall-effect thrusters is considered a sensitive topic in China, with scientists "working to improve the technology without attracting attention". Hall-effect thrusters are created with manned mission safety in mind with effort to prevent erosion and damage caused by the accelerated ion particles. A magnetic field and specially designed ceramic shield was created to repel damaging particles and maintain integrity of the thrusters. According to the Chinese Academy of Sciences, the ion drive used on Tiangong has burned continuously for 8,240 hours without a glitch during testing, indicating their suitability for Chinese space station's designated 15-year lifespan.[48] These are the world's first Hall thrusters on a human-rated mission.[49]

Experiments

The space station will have more than 20 experimental racks with enclosed, pressurized environment. Over 1,000 experiments are tentatively approved by China Manned Space Agency.[50] The programmed experiment equipment for the three modules as of June 2016 are:[9]

  • Space life sciences and biotechnology
    • Ecology Science Experiment Rack (ESER)
    • Biotechnology Experiment Rack (BER)
    • Science Glove-box and Refrigerator Rack (SGRR)

Planned Chinese space station telescope currently under development. It will feature a 2 meter (6.6 foot) diameter primary mirror and is expected to have a field of view 300 times larger than the Hubble Space Telescope. This will allow the telescope to image up to 40 percent of the sky using its 2.5 gigapixel camera over ten years. It will co-orbit with the space station, which will allow for periodic docking with the station.

Construction

Planning

In 2011, the space station was planned to be assembled during 2020 to 2022.[52] By 2013, the space station's core module was planned to be launched earlier, in 2018, followed by the first laboratory module in 2020, and a second in 2022.[53] By 2018, this had slipped to 2020-2023.[24][54] A total of 11 launches are planned for the whole construction phase, now beginning in 2021.[55][56]

Assembly

The assembly method of the station can be compared with the Soviet-Russian Mir space station and the Russian orbital segment of the International Space Station. The construction of the modular station marks China to be the second nation to develop and use automatic rendezvous and docking for modular space station construction. The docking and assembly mechanisms of the Tiangong station are based on, or compatible with, Russian design due to two iterations of cooperation in the past. During the cordial Sino-Soviet relations of the 1950s, the Soviet Union (USSR) engaged in a cooperative technology transfer program with the PRC, which helped kick-start the Chinese space program. The friendly relationship between the two countries turned to confrontation due to ideological difference on Marxism. As a consequence, all Soviet technological assistance was abruptly withdrawn after the 1960 Sino-Soviet split. The cooperation only restarted after the fall of the Soviet Union. In 1994, Russia sold some of its advanced aviation and space technology to the Chinese. In 1995 a deal was signed between the two countries for the transfer of Russian Soyuz spacecraft technology to China. Included in the agreement was training, provision of Soyuz capsules, life support systems, docking systems, and space suits. In 1996, two Chinese astronauts, Wu Jie and Li Qinglong, began training at the Yuri Gagarin Cosmonaut Training Center in Russia. After training, these men returned to China and proceeded to train other Chinese astronauts at sites near Beijing and Jiuquan. The hardware and information sold by the Russians led to modifications of the original Phase One spacecraft, eventually called Shenzhou, which loosely translated means "divine vessel". New launch facilities were built at the Jiuquan launch site in Inner Mongolia, and in the spring of 1998 a mock-up of the Long March 2F launch vehicle with Shenzhou spacecraft was rolled out for integration and facility tests.[57]

A representative of the Chinese crewed space program stated that around 2000, China and Russia were engaged in technological exchanges regarding the development of a docking mechanism used for space station.[58] Deputy Chief Designer, Huang Weifen, stated that near the end of 2009, the Chinese agency began to train astronauts on how to dock spacecraft.[59]

International co-operation

See also: China exclusion policy of NASA

China's incentive to build its own space station was amplified after NASA refused Chinese participation in the International Space Station in 2011,[60] a move that was criticized by various parties,[61][62][63] with China, Russia and Europe intending to keep a cooperative and multilateral approach in space.[64] Cooperation in the field of crewed space flight between the China Manned Space Agency (CMSA) and the Italian Space Agency (ASI) was examined in 2011, participation in the development of China crewed space stations and cooperation with China in the fields such as visiting astronauts, and scientific research was discussed.[65] An initial cooperative agreement with China National Space Administration and Italian Space Agency was signed in November 2011, covering collaboration areas of space transportation, telecommunications, Earth observation, etc.[66] Italian experiment High Energy cosmic-Radiation Detection (HERD) is scheduled to be onboard the Chinese station.[67] Tiangong also involves cooperation from France, Sweden, and Russia.[68]

On 22 February 2017, CMSA and Italian Space Agency (ASI) signed an agreement to cooperate on long-term human spaceflight activities.[69] The agreement holds importance due to Italy's leading position in the field of human spaceflight with regard to the creation and exploitation of the International Space Station (Node 2, Node 3, Columbus, Cupola, Leonardo, Raffaello, Donatello, PMM, etc.) and it signifies Italy's increased anticipation in China's developing space station programme.[70] European Space Agency (ESA) started human spaceflight training with CMSEO in 2017, with the ultimate goal of sending ESA astronauts onto Chinese space station.[71]

International experiments are selected by CMSA and United Nations Office for Outer Space Affairs (UNOOSA) on a UN session in 2019. 42 applications were submitted and nine experiments were accepted.[72] Some of the experiments are a continuation to the ones on Tiangong-2 such as POLAR-2, an experiment of researching Gamma-ray burst polarimetry, proposed by Switzerland, Poland, Germany and China.[73] Tricia Larose from the University of Oslo of Norway develops a cancer research experiment for the station. The 31-days experiment will test to see if weightlessness has a positive effect in stopping cancer growth.[74] Tiangong is also expected to host experiments from Belgium, France, Germany, India, Italy, Japan, Kenya, the Netherlands, Mexico, Peru, Russia, Saudi Arabia, and Spain.[73]

Regarding the participation of foreign astronauts, CMSA repeatedly communicated their support for such proposal. On the press conference of Shenzhou 12 mission, Zhou Jianping, the chief designer of China Manned Space Program explained that multiple countries have expressed their wish in the participation. He told journalists that foreign astronauts' future participation "will be guaranteed".[75] Ji Qiming, an assistant director at CMSEO told reporters that he believes "in the near future, after the completion of the Chinese space station, we will see Chinese and foreign astronauts fly and work together."[76]

Life aboard

The station has a Wi-Fi network for wireless connection. Each astronaut wears a bone-conduction headphone and microphone for easy communication.[77] 120 different types of food, selected based on astronauts' preference, are stored aboard. Staples including shredded pork in garlic sauce, kung pao chicken, black pepper beef, pickled cabbage and beverages, including a variety of teas and juices, are resupplied by trips of the Tianzhou-class cargo ship. Fresh fruits and vegetables are stored in coolers. Huang Weifen, chief astronaut trainer of CNSA, explains that most food is prepared to be solid, boneless, small-piece. Condiments such as pork sauce and Sichuan pepper sauce are used to compensate for the changes in the sense of taste in microgravity. The station is equipped with a small kitchen for food preparation and the first-ever microwave oven in spaceflight[78] so that astronauts can "always have hot food whenever they need."[79][80]

The station core module Tianhe provides living quarters for the crew members,[81][82] containing three separate bedrooms, toilet, shower facility, and gym equipment.[83] The crew cabins are substantially larger than that of International Space Station, featuring a wide twin mattress, a small window, a headphone, ventilation and other amenities. Neuromuscular electrical stimulator is used to prevent muscle atrophy. The noise level in the working area is 58 decibels, while in the sleeping area, the noise is kept at 49 decibels.[84][85]

Operation

The station will be resupplied by crewed and robotic spacecraft.

Crewed mission

The first spacewalk of Shenzhou 13 crew on Tiangong on November 7, 2021. The astronauts were Zhai Zhigang and Wang Yaping, the first female Chinese astronaut to perform a spacewalk.

Initial crewed missions to Tiangong, including its first mission Shenzhou 12 which lasted the planned 90 days, use the Shenzhou spacecraft. Subsequent missions starting with Shenzhou 13 will last a planned 180 days, this will then become the normal mission duration at Tiangong.[86]

China is testing a next-generation crewed spacecraft to eventually replace Shenzhou. It is designed to carry astronauts to the Chinese space station and offer the capability for lunar exploration. China's next-generation crew carrier is reusable with a detachable heat shield built to handle higher-temperature returns through Earth's atmosphere. The new capsule design is larger than the Shenzhou, according to Chinese officials. The spacecraft is capable of carrying astronauts to the Moon, and can accommodate up to six to seven crew members at a time, three more astronauts than Shenzhou.[87] The new crewed spacecraft has a cargo section that allows astronauts to bring cargo back to Earth, whereas the Tianzhou cargo resupply spacecraft is not designed to bring any cargo back to Earth.[87]

Cargo resupply

Main article: Tianzhou (spacecraft)

Tianzhou (Heavenly Vessel), a modified derivative of the Tiangong-1 spacecraft, will be used as robotic cargo spacecraft to resupply this station.[88] The launch mass of Tianzhou is expected to be around 13,000 kg with a payload of around 6,000 kg.[89] Launch, rendezvous and docking shall be fully autonomous, with mission control and crew used in override or monitoring roles. This system becomes very reliable with standardisations that provide significant cost benefits in repetitive routine operations. An automated approach could allow assembly of modules orbiting other worlds prior to crewed missions.[90]

End of mission

Tiangong is designed to be used for 10 years which could be extended to 15 years[107] and will accommodate three astronauts.[108] Chinese crewed spacecraft use deorbital burns to slow their velocity, resulting in their re-entry to the Earth's atmosphere. Vehicles carrying a crew have a heat shield which prevents the vehicle's destruction caused by aerodynamic heating upon contact with the Earth's atmosphere. The station itself has no heat-shield; however, small parts of space stations can reach the surface of the Earth, so uninhabited areas will be targeted for de-orbit manoeuvres.[53]
