The nation’s Shenzhou XXIII manned space mission is due to lift off into orbit late on Sunday night, sending three crew members, including Hong Kong’s first astronaut Lai Ka-ying, to the Tiangong space station.

Before setting off, mission commander and spaceflight engineer Colonel Zhu Yangzhu, spacecraft pilot Colonel Zhang Zhiyuan, Hong Kong’s science payload specialist Lai had carried out comprehensive, systematic, and in-depth preparations for the mission. Let's take a look at some of the highlights from their ground training.

The crew members will travel aboard the Shenzhou XXIII spacecraft to the Tiangong space station which is orbiting the Earth at an altitude of about 400 kilometers.

Lai will be the fourth Chinese woman to go into orbit and also the first female civilian astronaut. She had served in the Hong Kong Police Force before being selected as a national astronaut, having joined the national aerospace force in August 2024.

Lai had completed more than 200 training tasks, totaling more than 1,700 hours.
