Tiangong-3 (Chinese: ; pinyin: Tiāngōng sānhào; lit. 'Heavenly Palace 3') was a proposed Chinese space station that was part of the Tiangong program. The China National Space Agency (CNSA) initially planned to launch Tiangong-3 around 2015, following the launch of the Tiangong-2 test laboratory, which was originally planned for 2013. However, the goals for the Tiangong-2 and Tiangong-3 laboratories were merged, and the latter was not ordered. Eventually, the first module of the third station of the Tiangong program, Tiangong space station, was launched in 2021.
