China Space Station
Tiangong, officially the Tiangong space station, is a space station constructed by China and operated by China Manned Space Agency in low Earth orbit between 340 and 450 km above the surface. It is China's first long-term space station and the core of the "Third Step" of the China Manned Space Program; it has a mass between 90 and 100 t, roughly one-fifth the mass of the International Space Station and about the size of the decommissioned Russian Mir space station. The construction of the station is based on the experience gained from its precursors, Tiangong-1 and Tiangong-2. The first module, the Tianhe core module, was launched on 29 April 2021, followed by multiple crewed and uncrewed missions and two more laboratory cabin modules Wentian launched on 24 July 2022 and Mengtian launched on 31 October 2022. The research conducted on the station aims to improve researchers' ability to conduct science experiments in space.
