Shenzhou-23 Mission Successfully Launches, Sending Three Chinese Astronauts on Year-Long Space Mission

China successfully launched the crewed Shenzhou-23 spacecraft from the Jiuquan Satellite Launch Centre in northwest China on Sunday evening (24 May 2026) local time. Transported by the Long March-2F rocket, the mission delivered three astronauts to the Tiangong Space Station, currently orbiting Earth. Shenzhou-23 will automatically and rapidly approach and dock with the space station complex, followed by a handover of duties with the Shenzhou-21 crew currently aboard Tiangong. This Shenzhou-23 mission carries an ambitious agenda: breaking the record for the longest continuous stay in space at one full year. The previous record of 204 days in orbit was held by the Shenzhou-21 crew until last Sunday. “Assigning an astronaut to stay in orbit for a year is not merely doubling the duration of two six-month missions,” said CMSA spokesperson Zhang Jingbo, as reported by Xinhua. The extended mission demands significantly higher physical and mental preparedness. Chinese Astronaut Centre expert Bian Qiang explained that the team has strengthened the astronauts’ physical resilience and physiological function reserves, while intensifying psychological endurance training and crew compatibility exercises during their stay. Over the coming year, China will implement its first space-based human body research programme. The research aims to gather critical data on human adaptation limits in the vacuum of space and create a multi-system human body atlas for space. This data will be used to enhance medical systems and health protections for astronauts on future long-duration missions. The three astronauts aboard this mission have highly specialised expertise, led by mission commander Zhu Yangzhu (flight engineer), alongside Zhang Zhiyuan (spacecraft pilot) and Li Jiaying (payload specialist). Li Jiaying (also known as Lai Ka-ying in Cantonese pronunciation) immediately captured public attention. Before being selected as China’s fourth-generation astronaut, Li was an active member of the Hong Kong Police Force. Through this mission, Li has made history as the first resident of the Hong Kong Special Administrative Region to travel to space, and the fourth female astronaut for the country. Li’s presence has inspired and generated enthusiasm among Hong Kong’s youth. Lee Cheuk Hei Trevis, a student who watched the launch ceremony live, said he felt deeply motivated.
