China successfully launched its Shenzhou-23 crewed spacecraft Sunday night, achieving a critical milestone for Beijing’s aerospace ambitions and its overarching goal of putting humans on the Moon by 2030. The mission marks two historic firsts for the Chinese space program: the inclusion of an astronaut from Hong Kong and plans for a marathon, year-long orbital deployment for one of its crew members.
The Long March 2-F carrier rocket lifted off at 11:08 p.m. Beijing time from the Jiuquan Satellite Launch Center in northwestern China. About ten minutes later, the China Manned Space Agency (CMSA) declared the launch a “complete success” after the spacecraft safely separated from the rocket and entered its designated orbit.
The three-member crew heading to the Tiangong (“Heavenly Palace”) space station includes:
-
Zhu Yangzhu (39): Mission commander and experienced spaceflight engineer.

-
Zhang Zhiyuan (39): Spacecraft pilot and former Air Force pilot embarking on his first space mission.
-
Li Jiaying (43): Also known as Lai Ka-ying in Cantonese, she is a payload specialist and computer forensics expert who previously served as a superintendent in the Hong Kong Police Force.
Li’s inclusion marks the first time an ordinary citizen from the semi-autonomous region of Hong Kong has joined a Chinese crewed space mission. She also becomes the fourth Chinese woman ever to travel into space.
While standard rotations aboard the Tiangong space station typically last six months, a primary objective of the Shenzhou-23 mission is a grueling, 12-month orbital stay experiment involving one of the crew members. The CMSA stated that the specific astronaut chosen for the extended deployment will be designated later as operations unfold in orbit.

The year-long mission is designed to closely monitor and study the extreme physical and psychological toll of microgravity on the human body, including bone density loss, muscle wasting, radiation exposure, sleep disturbances, and behavioral fatigue.
Space authorities noted that gathering this data is absolutely vital for upgrading medical support systems and mapping out operational blueprints for future deep-space travel, including long-duration lunar and eventual Martian expeditions.
While aboard Tiangong, the crew will replace the current occupants, who have spent over 200 days in orbit and are nearing a national record for continuous flight. The new crew will spearhead more than 100 cutting-edge scientific experiments.
These trials will span space life sciences, materials science, and microgravity fluid physics—notably utilizing zebrafish embryos, mouse embryos, and stem-cell-derived “artificial embryos” to study reproduction and development systems in zero gravity.

The milestone mission comes amidst a continuing space race between Beijing and Washington. Blocked from collaborating with NASA and participating in the International Space Station (ISS) since 2011 due to U.S. legislation, China built its own independent outpost, operationalizing Tiangong in 2022.
As the ISS nears its planned retirement in 2031, Beijing is actively looking to expand its station and broaden global reach, announcing plans to host its first foreign astronaut—a Pakistani national currently undergoing training—by the end of 2026.
