Tiangong-3 ( Chinese: 天 宫 三 号; 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 merged, and the latter was therefore not ordered. [3] [1] The first module of the third station of the Tiangong program, Tiangong space station, was eventually launched in 2021.
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 was expected to provide:
"天宫二号"后,不再开发"天宫三号",中国将直接进入空间站时代,空间站预计2022年建成 (After "Tiangong-2", no longer develop "Tiangong-3", China will directly enter the era of space station, the space station is expected to be completed in 2022)
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.

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".
