The Tiangong program (Chinese: 天宫空间站工程; pinyin: Tiāngōng kōngjiānzhàn gōngchéng) is China's space program to create a modular space station, comparable to Mir. This program is independent and unconnected to any other international space-active countries. The program is part of the China Manned Space Program that began in 1992. The core module, the Tianhe ("Harmony of the Heavens") was finally launched on 29 April 2021 marking the start of the Tiangong Space program deployment.
