The spacecraft, Shenzhou-16, or “Divine Vessel”, and its three passengers lifted off atop a Long March-2F rocket from the Jiuquan Satellite Launch Centre in the Gobi Desert in northwest China at 9.31 a.m. (0131 GMT).
The astronauts on Shenzhou-16 will replace the three-member crew of the Shenzhou-15 that arrived at the space station late in November.
The space station, comprising three modules, was completed at the end of last year after a total of 11 crewed and uncrewed missions since April 2021 initiated by the launch of the first and biggest module – the station’s main living quarters.
China has already announced plans to expand its permanently inhabited space outpost, with the next module slated to dock with the current T-shaped space station to create a cross-shaped structure.
