China Launches 3-Astronaut Shenzhou-23 Mission for 1-Year Tiangong Stay

Summary
May 24's Shenzhou-23 launch sent three astronauts to Tiangong, where one crew member is expected to remain about a year—setting a new Chinese human-spaceflight endurance record.
The mission is designed to test how astronauts, equipment and life-support systems perform over longer stays, data Beijing sees as critical for a crewed Moon landing before 2030.
Zhu Yangzhu, Zhang Zhiyuan and Lai Ka-ying docked about 3.5 hours after liftoff; Lai became the first astronaut from Hong Kong, and the crew began a handover with the Shenzhou-21 team.
More than 100 experiments are planned, spanning life science, aerospace medicine, materials and perovskite solar cells, alongside studies of zebrafish, mouse embryos and rice grown across two orbital generations.
The flight also fits into a broader lunar buildup that includes future Long March-10, Mengzhou and Lanyue tests, while Tiangong cargo missions are already carrying tools such as a 6.8-ton resupply load with greenhouse-gas monitoring equipment.

Overview
The Shenzhou-23 mission, launched on May 24, 2026, carried three Chinese astronauts—Lai Ka-ying, Zhu Yangzhu, and Zhang Zhiyuan—into orbit aboard a Long March-2F Y23 rocket from the Jiuquan Satellite Launch Center. This mission marks a major step in China’s ambitious space program, which aims for a crewed moon landing by 2030. Zhu Yangzhu, the first spaceflight engineer to command a mission, leads the crew. The mission features a record-setting year-long stay for one astronaut on the Tiangong space station, supporting research on human adaptation in space and advancing China’s deep-space exploration goals.
