China will launch the Tianhe core module of its first permanent space station aboard a Long March-5B Y2 rocket from the Wenchang Spacecraft Launch Site during the first half of 2021, according to the chief designer of China’s human spaceflight program. Xinhua reports:
“Subsequent space missions include the launches of Tianzhou-2 cargo craft and Shenzhou-12 manned craft after the core module is sent into orbit,” Zhou [Jianping] said.
China is scheduled to complete the construction of the space station around 2022.
Two experiment modules named Wentian and Mengtian will be attached to the core. Launches of the new modules are scheduled for 2021 and 2022.
The space station will be similar in size to the Mir space station built by the Soviet Union during the 1980’s. It will have a mass about one-quarter that of the International Space Station.
Chinese astronauts will travel to the space station using three-seat Shenzhou spacecraft. Later flights will be aboard the nation’s next-generation crewed spacecraft, which will be capable of carrying six or seven astronauts. The next-generation vehicle is being designed for trips to the moon.
Robotic Tianzhou-2 spacecraft capable of carrying around 6,000 kg of cargo will resupply the station.
