Tiangong-3 (Chinese: ; pinyin: Tiāngōng sānhào; lit. 'Heavenly Palace 3') was a proposed Chinese space station, part of the Tiangong program. The China National Space Agency (CNSA) was originally expected to launch Tiangong-3 around 2015, following the launch of the Tiangong-2 test laboratory, originally planned for 2013.[2] The goals for the Tiangong-2 and Tiangong-3 laboratories were eventually merged, and the latter was therefore not ordered.[3][1]


In 2008, the China Manned Space Engineering Office (CMSEO) published a brief description of Tiangong-2 and Tiangong-3, indicating that several crewed spaceships would be launched in the late 2010s to dock with Tiangong-3.[4] The first Tiangong module, Tiangong-1, was launched in September 2011, and docked with the uncrewed Shenzhou 8 spacecraft in November 2011, marking China's first orbital docking.[5]


Tiangong-3's 22-metric-ton core module was expected to be around 18.1 m (59 ft) long and have a maximum diameter of 4.2 m (14 ft).[6] It was expected to provide:

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".
