The crew of China's Shenzhou XX spacecraft successfully completed their second spacewalk outside the Tiangong space station on June 26, 2025. This significant mission involved astronauts Chen Gaogao and Chen Zhongxu, who spent approximately eight hours conducting vital tasks outside the orbital complex. Commander Chen Gaogao led the EVA, with astronaut Chen Zhongxu also participating.
During the spacewalk, the astronauts installed protective shields against space debris, performed inspections of external equipment, and carried out necessary repairs. This extravehicular activity (EVA) marked the 22nd spacewalk conducted by Chinese astronauts and was notable as the first to be entirely executed by third-generation astronauts. These astronauts represent a new era of talent in China's expanding space program.
The Shenzhou XX crew has been stationed aboard Tiangong for over five months, engaging in numerous scientific experiments and technical operations. Their return to Earth is anticipated for July 2025. The Tiangong space station, orbiting at approximately 400 kilometers, is a key component of China's independent space endeavors, featuring a core module and two experimental modules.
With a projected operational lifespan of at least a decade, Tiangong serves as a hub for national scientific and technological research. Its modular design and advanced life support systems facilitate long-duration stays for astronauts. The station is slated to host thousands of research projects over the next 10-15 years, focusing on areas such as space life sciences and microgravity physical sciences.
China's space program is also looking towards future ambitious goals, including a crewed mission to the Moon by 2030. Advancements in spacesuit technology, such as the Feitian suit, have been crucial in supporting the increasing number of extravehicular activities, demonstrating enhanced reliability and durability.
