Concept
Tiangong space station
Summary
Tiangong (), officially the Tiangong space station (), is a permanently crewed space station constructed by China and operated by China Manned Space Agency in low Earth orbit between 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 (12,000 cu ft), slightly over one third the size of the International Space Station.
The construction of the station is based on the experience gained from its precursors, Tiangong-1 and Tiangong-2. The first module, the Tianhe ("Harmony of the Heavens") core module, was launched on 29 April 2021, followed by multiple crewed and uncrewed missions and two more laboratory cabin modules Wentian ("Quest for the Heavens") launched on 24 July 2022 and Mengtian ("Dreaming of the Heavens") launched on 31 October 2022. The space station aims to provide opportunities for space-based experiments and a platform for building capacity for scientific and technological innovation.
The names used in the space program, previously all chosen from the revolutionary history of the People's Republic, have been replaced with mystical-religious ones. Thus, the new Long March launch vehicles were renamed Divine Arrow (神箭), space capsule Divine Vessel (神舟), spaceplane Divine Dragon (神龙), land-based high-power laser Divine Light (神光), and supercomputer Divine Might (神威).
These poetic names continue as the first, second, third, fourth, fifth and future probes of the Chinese Lunar Exploration Program are called Chang'e – after the Moon goddess. The name "Tiangong" means "heavenly palace". Across China, the launch of Tiangong-1 was reported to have inspired a variety of feelings, including love poetry. The rendezvous of the space vehicles has been compared to the reunion of the cowherd and the weaver girl.
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.
