China is preparing to launch one of its most ambitious human space missions yet.
With the Shenzhou-23 spacecraft scheduled to carry three astronauts to the Tiangong space station on Sunday. The mission is expected to include China’s longest-ever stay in orbit, as Beijing intensifies efforts toward its goal of landing astronauts on the moon by 2030.
The spacecraft will lift off aboard a Long March-2F Y23 rocket from the Jiuquan Satellite Launch Center in northwest China. Among the three-member crew is Li Jiaying, a former Hong Kong police inspector who will become the first astronaut from Hong Kong to participate in a Chinese space mission. The crew also includes commander Zhu Yangzhu and pilot Zhang Yuanzhi from China’s People’s Liberation Army astronaut corps.
China Pushes Boundaries in Human Spaceflight
One of the astronauts is expected to remain aboard the Tiangong space station for an entire year — the longest mission duration ever attempted by China. The final decision on which crew member stays behind will reportedly depend on how the mission progresses once in orbit.
The extended mission will allow Chinese scientists to study the long-term effects of space travel on the human body, including radiation exposure, bone density loss and psychological stress during prolonged stays in space.
China has steadily expanded its space programme over the last few years, regularly sending astronaut crews to Tiangong for six-month missions since 2021. The latest mission marks another major step in the country’s rapidly growing ambitions beyond low-Earth orbit.
Growing Moon Race Between China and the US
The launch also comes amid intensifying competition between China and the United States over lunar exploration.
NASA is currently aiming for a crewed moon landing in 2028 under the Artemis programme, while China is targeting its own astronaut landing before 2030. Both countries view the moon as a critical stepping stone for future deep-space missions, including eventual human exploration of Mars.
The United States has repeatedly raised concerns about China’s long-term lunar ambitions, including potential plans related to lunar resources and infrastructure. Beijing, however, has rejected such allegations.
Meanwhile, private space company SpaceX recently completed another major test flight of its Starship rocket system, which is expected to play a key role in future NASA lunar missions.
China Eyes Permanent Lunar Base
China’s long-term vision extends far beyond a single moon landing. Beijing is aiming to establish a permanent lunar research base by 2035 in partnership with Russia.
To meet its ambitious 2030 deadline, Chinese engineers are currently testing several next-generation systems, including the heavy-lift Long March-10 rocket, the Mengzhou crew spacecraft and the Lanyue lunar lander.
The Shenzhou-23 mission will also test advanced autonomous docking technologies that are expected to become essential for future lunar missions.
Space Science and Human Experiments
Apart from technological milestones, the mission will also focus heavily on biological and medical research.
Chinese scientists are expected to study how humans adapt physically and psychologically to extended periods in space. State media has also reported that China recently launched experiments involving human stem cells aboard Tiangong to examine long-term human survival and reproduction in space environments.
The mission highlights how China is rapidly transforming itself into one of the world’s leading space powers as global competition over lunar exploration continues to intensify.
