Shenzhou-23 Docks at Tiangong: Hong Kong Astronaut Makes History
China’s Shenzhou-23 spacecraft successfully docked with the Tiangong space station on May 25, 2026, delivering a three-person crew that includes Li Jiaying — the first astronaut from Hong Kong to reach orbit. The mission, which launched from the Jiuquan Satellite Launch Center at 23:08 Beijing time on May 24, marks China’s 40th crewed spaceflight and the 644th flight of a Long March rocket, according to Xinhua News.
Historic Docking and Space Rendezvous
The Shenzhou-23 spacecraft completed its autonomous fast-docking procedure with the Tianhe core module’s radial port at 02:45 on May 25, a process that took approximately 3.5 hours. At 05:13, the Shenzhou-21 crew already aboard the station opened the hatch to welcome their colleagues, marking the eighth “space rendezvous” in China’s space history. The China Manned Space Engineering Office confirmed this was also the first time Tiangong has hosted an astronaut from Hong Kong.
The Crew: A Blend of Experience and Firsts
Commander Zhu Yangzhu, a flight engineer born in September 1986 in Jiangsu Province, is making his second spaceflight after serving on Shenzhou-16 in 2023. He is the first flight engineer to serve as a mission commander. “Eat your meal one bite at a time, walk your path one step at a time,” Zhu said at a press conference, as reported by People’s Daily. “No matter how big the goal, it requires down-to-earth persistence.”
Zhang Zhiyuan, born in June 1986 in Gansu Province, is a former PLA Air Force pilot making his first spaceflight. Selected in the third batch of astronauts in 2020, he described his approach with characteristic humility: “I am polishing myself piece by piece like a brick, letting myself serve the manned spaceflight cause.”
Li Jiaying: From Hong Kong Police to the Stars
The most closely watched crew member is Li Jiaying, a 43-year-old payload specialist born in Hong Kong with ancestral roots in Shunde, Guangdong. A PhD graduate in computer science from the University of Hong Kong, Li previously served as an IT expert in the Hong Kong Police Force, rising to the rank of Superintendent. She was selected as a payload specialist in the fourth batch of astronauts in June 2024 and joined the PLA Astronaut Corps in August 2024.
Li is China’s fourth female astronaut, the first from Hong Kong, the first fourth-batch astronaut to fly, the first female payload specialist, and notably, the first non-Party member astronaut. “As an ordinary Hong Kong person, being able to join the astronaut team and be selected for this mission fills my heart with gratitude and honor,” Li said, according to China News Service. “I sincerely thank the motherland for providing me with a stage to fulfill my dreams.”
Speaking to Hong Kong’s youth, she invoked the city’s iconic Lion Rock Spirit: “The Lion Rock Spirit of perseverance and never giving up is connected to the manned spaceflight spirit. Both require us to bravely challenge ourselves and persist to the end.”
Scientific Mission: Over 100 Experiments Planned
During its in-orbit stay, the Shenzhou-23 crew will conduct over 100 new science and application projects. According to 21st Century Business Herald, these span space life sciences — using zebrafish, mice, and stem cell-constructed artificial embryos — space materials science, microgravity fluid physics, space medicine, and new space technology verification.
A particularly significant component is China’s first one-year in-orbit stay experiment. One crew member will remain aboard Tiangong for a full year to collect long-duration health data and verify long-term health protection capabilities, providing critical data for future crewed lunar missions.
Broader Context: Lunar Ambitions and International Cooperation
The Shenzhou-23 mission comes amid China’s accelerating space program, which targets a crewed lunar landing by 2030. The country has integrated its crewed and robotic lunar exploration efforts into a unified “Lunar Exploration Project.” The Chang’e-7 lunar probe arrived at Wenchang in April 2026 and is preparing for a launch in the second half of the year.
Meanwhile, international cooperation is expanding. Two Pakistani astronauts are currently training at the China Astronaut Research and Training Center, with one expected to fly as a payload specialist on a short-term mission in the future.
What’s Next
With the crew safely aboard Tiangong, attention now turns to the in-orbit crew rotation between Shenzhou-21 and Shenzhou-23, the selection of the crew member for the one-year stay, and the execution of the ambitious scientific agenda. The mission represents another significant step in China’s journey toward becoming a leading space power, with Hong Kong now firmly part of that narrative.
