On March 21, 2025, the Shenzhou XIX crew successfully finished their third spacewalk outside China’s Tiangong space station. The China Manned Space Agency announced that Senior Colonel Cai Xuzhe and Lieutenant Colonel Song Lingdong worked outside the station for nearly seven hours, while Lieutenant Colonel Wang Haoze stayed inside to assist them. This mission marks another important step in China’s space exploration.

The astronauts used a robotic arm and received support from ground control to complete several tasks. They installed protective shields (盾) against space debris (碎片), set up external equipment, and checked the condition of devices outside the station. These efforts help ensure the space station’s safety and prepare it for future scientific work.

This spacewalk was the 20th ever conducted by Chinese astronauts. For Senior Colonel Cai, it was his fifth time working in space outside a spacecraft — a record for Chinese astronauts. Previously, he completed two spacewalks during the Shenzhou XIV mission in 2022. During the current Shenzhou XIX mission, Cai and Song made history in December 2024 by spending over nine hours outside Tiangong, breaking the world record set by American astronauts in 2001.

The Shenzhou XIX team, launched on October 30, 2024, from the Jiuquan Satellite Launch Center, became the eighth group to live and work on China’s space station. Since arriving, they have carried out numerous scientific experiments and technical tasks. Their work has provided valuable data for space research and shown China’s growing abilities in space technology.

The crew is scheduled to return to Earth in late April or early May 2025, ending their six-month mission. Their achievements remind us of the courage and skill required for space exploration while inspiring young people to learn about science and technology.
