China sends its youngest astronaut and four black mice to Chinese space station

China’s Shenzhou-21 space mission successfully launched on Friday from the Jiuquan Satellite Launch Centre, marking the seventh expedition to the Chinese space station since its completion in 2022.

This mission included a diverse crew, featuring the youngest astronaut in China’s program, Wu Fei, aged 32, alongside veteran Commander Zhang Lu, 48, and fellow astronaut Zhang Hongzhang, 39. The crew will spend six months aboard the Tiangong space station, taking over from the Shenzhou-20 team, who are set to return to Earth soon.

The Shenzhou-21 mission highlights a significant shift in China’s space exploration strategy, with a focus on integrating younger astronauts into the program.

This trend is evident in the participation of astronauts born in the 1990s and the ongoing biannual launches that have led to a series of achievements, including a world-record spacewalk. Additionally, this mission marks a notable milestone as it includes four black mice, the first small mammals sent to the Chinese space station for reproductive experiments in low Earth orbit, emphasizing China’s commitment to advancing scientific research in space.

As China’s space endeavors accelerate, they have prompted concerns in the United States, which is striving to ensure its own astronaut returns to the moon before China accomplishes that goal.
