On October 31, 2022 at 07:37 UTC, the new “Mengtian” ("Dreaming of the Heavens") module was launched from Wenchang Satellite Launch Center (WSLC), located in Wenchang on Hainan Island off China’s southern coastline. The module was orbited by the Chang Zheng-5B (Long March-5B) rocket-carrier. It is the second Laboratory Cabin Module launched, after “Wentian”, and the second module to extend the existing “Tianhe” core module of the station. The module will dock with the “Tianhe” core module on China’s “Tiangong” station later on October 24.
