On Aril 29, 2021 at 03:23 UTC the Chang Zheng-5B (Long March-5B) rocket-carrier was launched from Wenchang Satellite Launch Center (WSLC), located in Wenchang on Hainan Island off China’s southern coastline. The rocket orbited the “Tianhe” space station core module. It is the first element of the Chinese space station laying the keystone to a permanently-inhabited orbiting habitat that could welcome its first astronauts this summer. The liftoff of the Tianhe core module begins the most ambitious project in the history of China’s nearly 30-year human spaceflight program, which seeks to create a national space station after being shut out of the International Space Station, led by U.S. and Russian space agencies.
