Tiangong (Chinese: 天宫; pinyin: Tiāngōng; lit. 'Sky Palace'),[5][6] officially the Tiangong space station[7] (Chinese: 天宫空间站; pinyin: Tiāngōng kōngjiānzhàn), is a permanently crewed space station constructed by China and operated by China Manned Space Agency.[8] Tiangong is a modular design, with modules docked together while in low Earth orbit, between 340 and 450 km (210 and 280 mi) 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 space station aims to provide opportunities for space-based experiments and a platform for building capacity for scientific and technological innovation.[9]

The construction of the station is based on the experience gained from its precursors, Tiangong-1 and Tiangong-2.[10][11][12] The first module, the Tianhe ("Harmony of the Heavens") core module, was launched on 29 April 2021.[5][6] This was followed by multiple crewed and uncrewed missions and the addition of two laboratory cabin modules. The first, Wentian ("Quest for the Heavens"), launched on 24 July 2022; the second, Mengtian ("Dreaming of the Heavens"), launched on 31 October 2022.[10]
