Shenzhou-21 – China Launches Youngest Astronaut and Lab Mice to Tiangong Space Station

China successfully has launched the Shenzhou-21 mission to its Tiangong space station, carrying a three-member crew that includes the country’s youngest-ever astronaut and four laboratory mice. The mission marks another stride in China’s rapidly expanding space programme, which aims to send astronauts to the Moon by 2030.

Shenzhou-21 Lifts Off from Jiuquan Launch Centre

The Long March-2F rocket lifted off at 11:44 pm local time (1544 GMT) from the Jiuquan Satellite Launch Centre in northwest China’s Gobi Desert. The spacecraft is expected to dock with the Tiangong space station within three and a half hours of launch. Mission commander Zhang Lu, flight engineer Wu Fei, and payload specialist Zhang Hongzhang form the new crew for the six-month mission. At 32, Wu Fei is China’s youngest astronaut to enter orbit, representing the next generation of its space explorers.

Scientific Experiments and Rodent Study in Orbit

In a first for China, the mission carries four lab mice — two male and two female — for in-orbit biological experiments. These studies will examine the effects of microgravity on mammalian physiology and reproduction, forming part of China’s broader effort to prepare for long-duration lunar and interplanetary missions. The crew will also carry out multiple spacewalks, install anti-debris shields, and conduct educational outreach activities designed to inspire interest in science among young students.

Part of China’s Expanding ‘Space Dream’

China’s manned space programme, under President Xi Jinping’s ambitious “space dream” initiative, continues to accelerate. After landing the Chang’e-4 probe on the far side of the Moon in 2019 and deploying a rover on Mars in 2021, Beijing now plans a crewed lunar mission by the end of the decade. The Tiangong station, completed in 2022, remains central to these goals, serving as a permanent orbital base for research and astronaut training.

Exam Oriented Facts

• Shenzhou-21 launched on October 31, 2025, from Jiuquan, China.
• Wu Fei, aged 32, is China’s youngest astronaut to go into space.
• Four lab mice are part of China’s first in-orbit rodent experiments.
• The mission supports China’s 2030 goal for a crewed Moon landing.

Global Ambitions Amid ISS Exclusion

Since being excluded from the International Space Station in 2011, China has pursued an independent path in human spaceflight, building partnerships with countries like Pakistan to broaden international cooperation. The Shenzhou-21 mission highlights China’s growing technological capabilities and its strategic commitment to becoming a leading power in space exploration. The Tiangong crew’s work will play a key role in advancing life sciences and preparing for future deep-space missions.
