Tiangong 2

Tiangong-2 (Chinese: 天宫二号; pinyin: Tiāngōng èrhào; literally: "Celestial Palace 2") is a Chinese space laboratory and part of the Project 921-2 space station program. Tiangong-2 was launched on 15 September 2016. Tiangong-2 is neither designed nor planned to be a permanent orbital station; rather, it is intended as a testbed for key technologies that will be used in the Chinese large modular space station, which is planned for launch between 2019 and 2022.
