Shenzhou-23 Launches With Hong Kong’s First Astronaut Aboard
China launched the Shenzhou-23 spacecraft on May 24 at 23:08 Beijing time from the Jiuquan Satellite Launch Center, sending three astronauts to the Tiangong space station in a mission that marks several historic firsts. The crew includes Li Jiaying, the first astronaut from Hong Kong, and the mission will feature China’s first one-year in-orbit stay experiment, according to the China Manned Space Agency.
A Historic Crew
The Shenzhou-23 flight crew consists of Commander Zhu Yangzhu, Pilot Zhang Zhiyuan, and Payload Specialist Li Jiaying. Zhu Yangzhu, a veteran astronaut who previously flew on Shenzhou-16 in 2023, leads the mission. Zhang Zhiyuan, a former Air Force pilot selected in China’s third batch of astronauts, is making his first spaceflight.
Li Jiaying’s presence on the crew carries profound symbolic weight. Born in Hong Kong and holding a PhD in Computer Forensics from the University of Hong Kong, she served as a Police Superintendent in the Hong Kong SAR Government before being selected as a fourth-generation payload specialist in June 2024. She is the first astronaut from Hong Kong, the first fourth-generation Chinese astronaut to fly, and the first female payload specialist selected from the Hong Kong and Macau regions.
“Hong Kong’s first participation of a scientific researcher in a flight mission not only affirms her personal capabilities but also fully demonstrates the nation’s high recognition of Hong Kong’s innovation and technology talent,” said Hong Kong Chief Executive John Lee, who congratulated Li Jiaying on her selection.
Pioneering Long-Duration Spaceflight
A standout feature of the Shenzhou-23 mission is the plan for one crew member to conduct a one-year in-orbit stay experiment — China’s first such long-duration human spaceflight study. CMSA spokesperson Zhang Jingbo explained that the experiment will implement China’s first space human research program, comprehensively gather longer-term astronaut flight data, and verify long-duration flight health support capabilities.
“The one-year space stay will provide longer-term continuous research opportunities for scientific projects and related technology verification,” Zhang Jingbo said. The specific crew member who will remain aboard for the full year will be determined based on in-orbit task execution.
Mission Objectives and Scientific Agenda
This is the seventh crewed mission of China’s space station application and development phase and the 40th flight mission of the country’s crewed space program. After launch, Shenzhou-23 will perform autonomous fast rendezvous and docking with the Tianhe core module’s radial port, forming a three-ship, three-module combination.
The crew will replace the Shenzhou-21 astronauts currently aboard the station. During their mission, they will conduct extravehicular activities, cargo transfer operations, install and retrieve external payloads, carry out science education activities, and perform over 100 new scientific experiments. These experiments will focus on space life sciences, space materials science, microgravity fluid physics, space medicine, and new space technologies.
Hong Kong’s Growing Role in Space
Li Jiaying’s flight is the culmination of Hong Kong’s deepening integration into China’s space program. The Tianzhou-10 cargo spacecraft, launched on May 11, carried a lightweight greenhouse gas point-source detection instrument developed by Hong Kong universities. The Hong Kong SAR Government has also established the Hong Kong Space Robotics and Energy Center under the InnoHK innovation platform, and Hong Kong research institutions have contributed to lunar and Mars exploration missions.
A delegation led by Hong Kong Secretary for Innovation, Technology and Industry Sun Dong traveled to Jiuquan for the crew send-off ceremony, underscoring the territory’s stake in the mission.
Broader Implications
The one-year stay experiment positions China to gather critical biomedical data for future deep-space missions, including planned crewed lunar expeditions. This parallels the long-duration experience gained by Russian and American programs through the Mir space station and International Space Station.
China is also expanding international cooperation in space. Two Pakistani astronauts are currently training alongside Chinese astronauts at the China Astronaut Research and Training Center, with one expected to fly as a payload specialist on a short-term mission. This signals China’s growing role as an alternative partner for nations seeking access to space.
What’s Next
Following the Shenzhou-23 launch, China’s 2026 space agenda includes the Shenzhou-24 mission later this year and the maiden flight of the Mengzhou-1 new-generation crewed spacecraft. The Chang’e-7 lunar mission is also scheduled for the second half of 2026, demonstrating the accelerating pace of China’s space exploration program.
For now, all eyes are on the rendezvous and docking sequence that will bring the Shenzhou-23 crew to the Tiangong station, where they will begin what promises to be a landmark mission for China’s human spaceflight program.
