Shenzhou-23 Launch: China’s Next Crewed Mission to Tiangong
5/24/2026, 4:17:48 AM
Mission Overview
On 24 May 2026 at 11:08 p.m. Beijing time (1508 GMT), a Long March-2F Y23 rocket lifted off from the Jiuquan Satellite Launch Center carrying the Shenzhou-23 spacecraft. The three-person crew—commander Zhu Yangzhu, pilot Zhang Zhiyuan (also reported as Zhang Yuanzhi), and payload specialist Lai Ka-ying (also cited as Li Jiaying)—will dock with the Tiangong space station, rotate the existing Shenzhou-21 crew, and begin a suite of scientific and technical tasks. One crew member will remain aboard for a planned one-year in-orbit residency, a first for China, though the agency has not yet identified which astronaut will stay.
Background and Tiangong Context
Tiangong’s three-module configuration was completed in late 2022 after successive Shenzhou-12, -13, -14, -15 and -16 flights. An emergency-readiness launch of the uncrewed Shenzhou-22 in 2025 provided a lifeboat after a debris-impact incident involving Shenzhou-20. The Tianzhou-10 cargo vessel arrived on 11 May 2026 delivering nearly 7 tonnes of supplies, supporting the upcoming crew rotation.
Crew Profiles
- Zhu Yangzhu – Flight engineer and commander; previously flew on Shenzhou-16.
- Zhang Zhiyuan – Spacecraft pilot; former PLA Air Force fighter pilot (some reports name him Zhang Yuanzhi).
- Lai Ka-ying – Payload specialist; former Hong Kong police superintendent, holder of a doctorate in computer forensics, and the first astronaut from the Hong Kong Special Administrative Region (also described as Li Jiaying).

Official Statements and Program Goals
CMSA spokesperson Zhang Jingbo confirmed the launch schedule, crew readiness and the mission’s objectives: crew rotation, extravehicular activities, cargo transfer, and a one-year residency experiment to gather comprehensive data on long-duration human physiology. He highlighted recent upgrades to window protection against space debris and affirmed that “the technical conditions, ground systems, and station status are all stable and fully prepared for the launch.” Commander Zhu Yangzhu emphasized responsibility for safety, coordination and zero-error execution. Hong Kong Chief Executive John Lee congratulated Lai Ka-ying on completing the rigorous selection and training process, underscoring Hong Kong’s contribution under the “One Country, Two Systems” framework.
Verbatim Quotes
- “She was extremely meticulous. She would follow through on every single detail as a student,” — Chow Kam-pui, honorary associate professor, University of Hong Kong.
- “In addition, one of the crew members will carry out a one-year in-orbit stay experiment. This one-year in space stay,is first to carry out China's first human research program in space, which will capture comprehensive data of astronauts' longer flight so as to enrich our experience in mission implementation. Second, it will test our ability to guarantee the astronaut's health over the long haul,” — Zhang Jingbo, CMSA spokesperson.
- “This is a ... test of our physical and psychological endurance, emergency response capabilities, coordination and teamwork, as well as our ability to work and live in orbit,” — Zhu Yangzhu, mission commander.
- “We now have a much clearer understanding of the space debris environment and what it takes to protect orbiting spacecraft from it.” — Zhang, CMSA official.
- “We believe that under the policy of One Country, Two Systems, Hong Kong will fully leverage its international strength to further attract and cultivate top sci-tech innovation talents and make contributions to the nation's manned space program,” — Zhang Jingbo, CMSA spokesperson.
- “Moreover, as I come from the Hong Kong Special Administrative Region (HKSAR), I have an additional task: to serve as a bridge between the HKSAR, the Macao Special Administrative Region and the aerospace industry of our motherland," Lai said.” — Lai Ka-ying, payload specialist.
Conflicting Reports and Information Gaps
Sources differ on the pilot’s name (Zhang Zhiyuan vs. Zhang Yuanzhi) and on the Hong Kong astronaut’s transliteration (Lai Ka-ying vs. Li Jiaying). While most reports state a six-month crew rotation, several note a planned one-year stay for an unspecified crew member, and the agency has not disclosed which astronaut will undertake the extended mission.
Implications for Long-Duration Flight and Lunar Plans
The year-long residency will provide unprecedented data on radiation exposure, bone density loss and psychological stress, directly supporting China’s goal of a crewed lunar landing by 2030 and a permanent lunar base by 2035. Successful execution also reinforces China’s emerging role in a multipolar space environment, highlighted by upcoming international participation such as Pakistani astronaut training.
Upcoming Steps
Later in 2026, Shenzhou-24 will carry a short-duration Pakistani astronaut, after which the year-long Shenzhou-23 crew member will remain aboard. Parallel milestones include the Long March-10 technical-verification flight, the maiden launches of the Mengzhou crewed capsule and the Lanyue lunar lander, and continued Tiangong operations.
