Tiangong-2 (Chinese : 天 宫 二 号 ; pinyin :Tiāngōng èrhào;lit.'Celestial Palace 2') was a Chinese space laboratory and part of the Project 921-2 space station program. Tiangong-2 was launched on 15 September 2016. [7] It was deorbited as planned on 19 July 2019. [8]
Tiangong-2 was neither designed nor planned to be a permanent orbital station;rather,it was intended as a testbed for key technologies used in the Tiangong station (Chinese large modular space station) of which the first module launched on 29 April 2021 [9] and the remaining modules of which launched in 2022. [10]
The China Manned Space Engineering Office published a brief description of Tiangong-2 and its successor Tiangong-3 in 2008, indicating that at least two crewed spaceships would be launched to dock with Tiangong-2. [2]
Tiangong-2 was originally expected to be launched by the China National Space Agency (CNSA) by 2015 [11] to replace the prototype module Tiangong-1, which was launched in September 2011. [12] In March 2011, Chinese officials stated that Tiangong-2 was scheduled to be launched by 2015. [11] [13] An uncrewed cargo spacecraft will dock with the station, [11] allowing for resupply. [14]
In September 2014, its launch was postponed to September 2016. [15] Plans for visits in October 2016 by the crewed mission Shenzhou 11 and the uncrewed resupply craft Tianzhou were made public. [16] The station was successfully launched from Jiuquan aboard a Long March 2F rocket on 15 September 2016. [17] Shenzhou 11 (Only Expedition) successfully docked with Tiangong-2 on 19 October 2016.[ citation needed ]
Aboard the Shenzhou 11, launched from Jiuquan Satellite Launch Center in the Gobi desert, were Commander Jing Haipeng and Chen Dong who formed the inaugural crew for the space laboratory. [18] It was China's first crewed mission for more than three years.
During the 30 days the two astronauts were aboard Tiangong-2, they conducted a number of scientific and technical experiments on the physiological effects of weightlessness, tests on human-machine collaboration on in-orbit maintenance technology and released an accompanying satellite successfully. Accompanying photography and near-distance fly-by observation were also carried out. They collected abundant data and made some achievements in programs of gamma-ray burst polarimeter, space cold atomic clock and preparation of new materials. [19]
Shenzhou 11 separated from the orbiting Tiangong-2 space laboratory on 17 November 2016, reentry module landed successfully at the expected site in central Inner Mongolia Autonomous Region at about 13:59 Beijing Time. [19]
On 22 April 2017, the cargo vessel Tianzhou-1 successfully docked with Tiangong-2 marking the first successful docking and refuelling with the orbiting space laboratory. [20] It subsequently performed a second docking and refueling on 15 June 2017. On 12 September 2017, Tianzhou-1 performed the third and final docking and refuelling with Tiangong-2, with what is termed a fast docking which took 6.5 hours, rather than 2 days, to complete. [21]
In June 2018, Tiangong-2 performed orbital maneuvers lowering the orbit to 292 × 297 kilometers, likely in preparation for deorbiting. It then returned to its usual orbit. [22] [23]
In July 2019, the China Manned Space Engineering Office announced that it was planning to deorbit Tiangong-2 in the near future, but no specific date was given. [24] The station subsequently made a controlled reentry on 19 July 2019 and burned up over the South Pacific Ocean. [25]
The dimensions of Tiangong-2 were:
Tianhe is the core module of the Chinese space station. The core module and its other parts launched between 2021 and 2022.
A space station is a spacecraft which remains in orbit and hosts humans for extended periods of time. It therefore is an artificial satellite featuring habitation facilities. The purpose of maintaining a space station varies depending on the program. Most often space stations have been research stations, but they have also served military or commercial uses, such as hosting space tourists.
The Tiangong program is China's space program to create a modular space station, comparable to Mir. This program is independent and unconnected to any other international space-active countries. The program is part of the China Manned Space Program that began in 1992. The core module of the Tiangong space station, the Tianhe was finally launched on 29 April 2021 marking the start of the Tiangong Space program deployment.
Tiangong, officially the Tiangong space station, is a permanently crewed space station constructed by China and operated by China Manned Space Agency. Tiangong is a modular design, with modules docked together while in low Earth orbit, between 340 and 450 km above the surface. It is China's first long-term space station, part of the Tiangong program and the core of the "Third Step" of the China Manned Space Program; it has a pressurised volume of 340 m3, slightly over one third the size of the International Space Station. The space station aims to provide opportunities for space-based experiments and a platform for building capacity for scientific and technological innovation.
Shenzhou 8 was an uncrewed flight of China's Shenzhou program, launched on 31 October 2011 UTC, or 1 November 2011 in China, by a Long March 2F rocket which lifted off from the Jiuquan Satellite Launch Center.
Shenzhou 10 was a crewed spaceflight of China's Shenzhou program that was launched on 11 June 2013. It was China's fifth crewed space mission. The mission had a crew of three astronauts: Nie Haisheng, who was mission commander and previously flew on Shenzhou 6; Zhang Xiaoguang, a former PLAAF squadron commander who conducted the rendezvous and docking; and Wang Yaping, the second Chinese female astronaut. The Shenzhou spacecraft docked with the Tiangong-1 trial space laboratory module on 13 June, and the astronauts performed physical, technological, and scientific experiments while on board. Shenzhou 10 was the 2nd and final expedition and mission to Tiangong-1 in this portion of the Tiangong program. On 26 June 2013, after a series of successful docking tests, Shenzhou 10 returned to Earth.
The China Manned Space Program, also known as Project 921 is a space program developed by the People's Republic of China and run by the China Manned Space Agency (CMSA) under the Equipment Development Department of the Central Military Commission, designed to develop and enhance human spaceflight capabilities for China. It was approved on 21 September 1992 and has been in operation ever since. The CMS commander and director are currently Xu Xueqiang and Zhou Jianping respectively; the latter has held this position since 2006, after taking over from Wang Yongzhi, who served as the first director from 1992 to 2006.
Tiangong-1 was China's first prototype space station. It orbited Earth from September 2011 to April 2018, serving as both a crewed laboratory and an experimental testbed to demonstrate orbital rendezvous and docking capabilities during its two years of active operational life.
Tianhe, officially the Tianhe core module, is the first module to launch of the Tiangong space station. It was launched into orbit on 29 April 2021, as the first launch of the final phase of Tiangong program, part of the China Manned Space Program.
The Chinese Docking Mechanism is a spacecraft docking mechanism based on the Androgynous Peripheral Attach System (APAS). There have been contradicting reports by the Chinese on its compatibility with APAS. It is used by Shenzhou spacecraft, beginning with an uncrewed Shenzhou 8, to dock to Tiangong-1. Subsequent crewed missions docked with the Tiangong-1, Tiangong-2 and the Tiangong space station. Similar docking mechanism was also introduced to the Tianzhou cargo spacecraft. Tianzhou 1 was the first cargo spacecraft which docked with the Tiangong-2. It has a circular transfer passage that has a diameter of 800 mm (31 in). The androgynous variant has a mass of 310 kg and the non-androgynous variant has a mass of 200 kg.
Shenzhou 11 was a crewed spaceflight of the Shenzhou program of China, launched on 17 October 2016 from the Jiuquan Satellite Launch Center. It was China's sixth crewed space mission, at 33 days, it was the longest until the follow-up Shenzhou 12 mission which lasted 3 months. Two days after launch, it docked with the Tiangong-2 space laboratory, which had been launched on 15 September 2016. Shenzhou 11 was the first and only expedition and mission to Tiangong-2 in this portion of the Tiangong program.
Tianzhou 1 was the debut mission of the Tianzhou-class uncrewed cargo spacecraft. It was developed as part of the crewed space program of China. Tianzhou means "heavenly vessel" in Chinese. On 20 April 2017, Tianzhou 1 was launched by rocket Long March 7 at China Wenchang Spacecraft Launch Site. It successfully docked with the Tiangong-2 space laboratory on 22 April 2017 at 12:16 (UTC+8). Tianzhou 1 was deorbited on 22 September 2017. It plunged into Earth's atmosphere and burned up after a set of braking maneuvers under ground control.
The Tianzhou is a Chinese automated cargo spacecraft developed from China's first prototype space station Tiangong-1 to resupply its modular space station. It was first launched on the Long March 7 rocket from Wenchang on April 20, 2017 and demonstrated autonomous propellant transfer.
Mengtian, officially the Mengtian laboratory cabin module, is a major module of the Tiangong space station. It is the second Laboratory Cabin Module launched, after Wentian, and the second module to extend the existing Tianhe core module of the station. It was launched into orbit from the Wenchang Spacecraft Launch Site on 31 October 2022, successfully docking with Tianhe forward port at 20:27 UTC on the same day.
Tianzhou 2 was a mission of the Tianzhou-class unmanned cargo spacecraft. The launch took place at 29 May 2021, 12:55:29 UTC. The spacecraft successfully docked with the Tiangong space station later on the same day.
Shenzhou 12 was a Chinese spaceflight to the Tiangong space station, launched on 17 June 2021. It carried three People's Liberation Army Astronaut Corps (PLAAC) taikonauts on board a Shenzhou spacecraft. The mission was the seventh crewed Chinese spaceflight and the twelfth flight overall of the Shenzhou program. It was the first flight to Tiangong, and the first Chinese crewed spaceflight since Shenzhou 11 in 2016.
Tianzhou 4 was the fourth mission of the Tianzhou-class uncrewed cargo spacecraft, and the third resupply mission to Tiangong Space Station carrying 5 tons of cargos and 1 ton of propellant. It is the largest load capacity cargo spacecraft that is on active duty. It launched on 9 May 2022, docking successfully with the Tiangong space station at the aft port 6 hours after launch. Like previous Tianzhou missions, the spacecraft launched from the Wenchang Satellite Launch Center in Hainan, China on a Long March 7 rocket.
Shenzhou 14 was a Chinese spaceflight to the Tiangong space station, launched on 5 June 2022. It carried three People's Liberation Army Astronaut Corps (PLAAC) taikonauts on board a Shenzhou spacecraft. The mission was the ninth crewed Chinese spaceflight and the fourteenth flight overall of the Shenzhou program.
Shenzhou 15 was a Chinese spaceflight to the Tiangong space station, launched on 29 November 2022. It carried three People's Liberation Army Astronaut Corps (PLAAC) taikonauts on board a Shenzhou spacecraft. The mission was the tenth crewed Chinese spaceflight and the fifteenth flight overall of the Shenzhou program.
Shenzhou 16 was a Chinese spaceflight to the Tiangong space station, launched on 30 May 2023. It carried two People's Liberation Army Astronaut Corps (PLAAC) taikonauts and a payload specialist from Beihang University on board a Shenzhou spacecraft. The mission was the eleventh crewed Chinese spaceflight and the sixteenth flight overall of the Shenzhou program.
China often chooses poetic names for its space projects, such as Chang'e – after the moon goddess – for its lunar probes; its rocket series, however, is named Long March, in tribute to communist history. The space station project is currently referred to as Tiangong, or "heavenly palace".
China is ready to carry out a multiphase construction program that leads to the large space station around 2020. As a prelude to building that facility, China is set to loft the Tiangong-1 module this year as a platform to help master key rendezvous and docking technologies.
