China Launches Shenzhou 23, Plans Yearlong Space Station Stay
China launched the Shenzhou 23 spacecraft Sunday night, May 24, 2026, from the Jiuquan Satellite Launch Center in northwestern China.[1]
One of the three crew members will remain aboard China's Tiangong space station for about one year to study human adaptability and performance in long-duration spaceflight.[2]
The mission crew is commander Zhu Yangzhu, along with Zhang Zhiyuan and Lai Ka-ying (also identified as Li Jiaying).[2] Lai Ka-ying was born and raised in Hong Kong and holds a doctoral degree in computer forensics.[2] She is the first astronaut from Hong Kong.[2] Shenzhou 23 will conduct dozens of science and application projects and will perform an in-orbit crew rotation with the Shenzhou 21 team.[2]
An earlier emergency Shenzhou mission last year returned a team of astronauts who had been stranded on Tiangong after a damaged spacecraft.[2]
Officials say the planned yearlong stay is intended to "explore human adaptability and performance limits" in extended space missions.[2]
