The Chinese large modular space station is a planned space station to be placed in Low Earth orbit. The planned Chinese Space Station will be roughly one-fifth the mass of the International Space Station and about the size of the decommissioned Russian Mir space station. The Chinese station is expected to have a mass between 80 and 100 metric tons. Operations will be controlled from the Beijing Aerospace Command and Control Center in China. The planned launch date of the core module, the Tianhe-1 (“Harmony of the Heavens”), is 2020. In 2017, the Chinese launched the Tianzhou-1 ("Heavenly Vessel") cargo spaceship, which is based on the Tiangong 1 & 2 space laboratories.
