On April 17, 2026, the China Manned Space Agency announced a key milestone in China’s low-Earth orbit space program: the three-person crew of the Shenzhou XXI mission, stationed aboard the country’s operational Tiangong space station, has successfully completed its third extravehicular activity (EVA), more commonly known as a spacewalk.
The outing, which concluded in the early hours of Friday Beijing time, saw two mission members — mission commander Senior Colonel Zhang Lu and spaceflight engineer Major Wu Fei — wrap up approximately five and a half hours of work outside the orbital outpost before re-entering the Wentian science module at 1:36 a.m. local time. The third member of the Shenzhou XXI team, payload specialist Zhang Hongzhang, an academic researcher from the Chinese Academy of Sciences, remained inside the station throughout the EVA to coordinate operations and provide critical in-station support to his extravehicular crewmates.
Working in tandem with ground control teams back on Earth and leveraging the station’s onboard robotic arm for maneuvering support, Zhang and Wu completed all pre-planned tasks scheduled for the spacewalk. These included the installation of protective space debris shields, designed to shield critical station components from micrometeoroid and orbital debris impacts, as well as comprehensive inspections of the condition of EVA support equipment stored outside the station.
This spacewalk marks not only a routine operational milestone for the Shenzhou XXI mission but also a historic first for China’s human spaceflight program. It is the 27th spacewalk conducted by Chinese astronauts since the country began its extravehicular activity program, and it is the seventh spacewalk for mission commander Zhang Lu. At 49 years old, the Hunan Province native now holds the new national record for the most spacewalks completed by any Chinese astronaut. Zhang previously notched four spacewalks during his first mission, the six-month long Shenzhou XV expedition that launched in November 2022, demonstrating his extensive experience and reliability in leading complex extravehicular operations.
