China challenges NASA: Shenzhou-23 mission and preparations to land on the Moon

Sunday evening (24 May 2026) from the Jiuquan cosmodrome in northwest China launched the Shenzhou-23 spacecraft.

This mission is simply a key component of the Chinese space program, which is increasingly challenging American dominance. On board was a three-man crew, and 1 of its members will spend the full year on the Tiangong orbital station – it is evidence time for Chinese astronautics.

Historical launch and first Hong Kong astronaut

The Shenzhou-23 ship, elevated by the Long March-2F Y23 carrier rocket, took mission commander Zhu Yangzhu, pilot Zhang Zhiyuan and cargo specialist Li Jiaying (also known under the Cantonese name Lai Ka-ying). The presence of the second on board is of peculiar symbolic and political importance.

43-year-old Li Jiaying is the first always astronaut from Hong Kong.

Prior to joining the space program, in which she underwent rigorous, over 2 years of training (including sleep deprivation, tests in an overload centrifuge and endurance in the desert), she served as the chief inspector in Hong Kong police, specializing in cybersecurity and forensics. Her participation in the mission, widely commented on by the authorities of the peculiar Administrative Region, is seen as evidence of Hong Kong's expanding integration into national technology programmes.

A year in space: investigating the limits of human endurance

The most crucial component of the Shenzhou-23 mission is the unprecedented, one-year stay of 1 of the astronauts at Tiangong Station. The decision to which of the crew will stay in orbit for that long is due to be made later. The Chinese missions to date usually lasted about six months.

As Zhang Jingbo, spokesperson for the Chinese Space Crew Agency (CMSA), the yearly mission is not just a “double duration”. Its main nonsubjective is to research the limits of human adaptation to long-term existence in microgravity conditions. Scientists plan to make a comprehensive “atlas of the human body in space”, exploring the effects of radiation, failure of bone density and intellectual stress.

As part of more than 100 technological experiments planned, the crew will be active in fish farming, mouse embryos and stem cells. Interestingly, China besides plans to grow rice for 2 successive generations in orbit to research the genetic stableness of plants in space.

Race to the Moon: China vs. USA

The Shenzhou-23 mission takes place in the shadow of an increasingly fierce space race between Beijing and Washington. China is consistently implementing a plan culminating in a manned landing on the Moon before the end of 2030. Last year Beijing successfully tested automated docking and equipment essential for the lunar mission.

The United States, through NASA Artemis, plans to return to the Silver Globe in 2028. Only in April of that year, 4 NASA astronauts took a historical flight around the Moon as part of the Artemis II mission, and a fewer days ago, SpaceX Elona Muska conducted a successful test of the powerful Starship rocket, which is expected to carry out American lunar missions in the future.

Chinese scientists, specified as the main designer of the Wu Weiren lunar program, propose that the authoritative agenda for landing in 2030 is deliberately “conservative”. The yearly mission at Tiangong Station is further evidence that China is not only catching up, but in any areas they begin to set fresh standards in space exploration.
