Taikonauter klara efter 90 dagar på kinesisk rymdstation

Tiangong (Chinese: 天宫; pinyin: Tiāngōng; lit. 'Heavenly Palace'), officially the Tiangong space station (Chinese: 天宫空间站), is a space station being constructed by China in low Earth orbit between 340 and 450 km (210 and 280 mi) above the surface. Being China's first long-term space station, it is the goal of the "Third Step" of the China Manned Space Program. Once completed, the Tiangong Space Station will have a mass between 80 and 100 t (180,000 and 220,000 lb), roughly one-fifth the mass of the International Space Station and about the size of the decommissioned Russian Mir space station but with more advanced technologies. The construction of the station are based on the experience gained from its precursors, Tiangong-1 and Tiangong-2. The first module, the Tianhe ("Harmony of the Heavens") core module, was launched on 29 April 2021, followed by multiple crewed and uncrewed missions and two more modules to be launched by 2022. Chinese leaders hope that research conducted on the station will improve researchers' ability to conduct science experiments in space, beyond the duration offered by China's existing space laboratories.
