Tiangong-2 ("Chinese: ; "pinyin: Tiāngōng èrhào; literally: "Celestial Palace 2") is a "Chinese space laboratory and part of the "Project 921-2 "space station program. Tiangong-2 was launched on 15 September 2016.[7]

Tiangong-2 is neither designed nor planned to be a permanent orbital station; rather, it is intended as a testbed for key technologies that will be used in the "Chinese large modular space station, which is planned for launch between 2019 and 2022.[8]

History[edit]

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 by 2015[9] to replace the prototype module "Tiangong-1, which was launched in September 2011.[10] In March 2011, Chinese officials stated that Tiangong-2 was scheduled to be launched by 2015.[9][11] An uncrewed cargo spacecraft will dock with the station,[9] allowing for resupply.[12]

In September 2014, its launch was postponed to September 2016.[13] Plans for visits in October 2016 by the crewed mission "Shenzhou 11 and the uncrewed resupply craft "Tianzhou were made public.[14] The station was successfully launched from "Jiuquan aboard a "Long March 2F rocket on 15 September 2016.[15] "Shenzhou 11 successfully docked with Tiangong-2 on 19 October 2016.[16]

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.[17] It was China's first manned 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.[18]

Shenzhou 11 separated from the orbiting Tiangong-2 space lab on November 17, reentry module landed successfully at the expected site in central "Inner Mongolia Autonomous Region at about 13:59 Beijing Time.[18]

On April 22, 2017, the cargo vessel "Tianzhou-1 successfully docked with Tiangong-2 marking the first successful docking and refuelling with the orbiting space laboratory.[19] It subsequently performed a second docking and refueling on June 15, 2017. On September 12, 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.[20]

The dimensions of Tiangong-2 are:

Further developments[edit]

"Tiānhé-1 is the core module of a planned modular space station. The core module and its other parts are to be launched between 2019 and 2022.
