4月29日11时23分，长征五号B遥二运载火箭搭载空间站天和核心舱，在海南文昌航天发射场发射升空。中国空间站建造任务实施阶段成功开启。按计划，中国将于2022年完成空间站在轨建造。

China sent into space the core module of its space station on April 29, kicking off a series of key launch missions that aim to complete the construction of the station by the end of next year. The Long March-5B Y2 rocket, carrying the Tianhe module, blasted off from the Wenchang Spacecraft Launch Site in Hainan province at 11:23 am.

天和核心舱发射成功，标志着我国空间站建造进入全面实施阶段，为后续任务展开奠定了坚实基础。

The successful launch of the core module Tianhe marks that China's space station construction has entered the full implementation stage, which lays a solid foundation for the follow-up tasks.
