In a significant milestone for China’s space program, the three-member crew of the Shenzhou XXI mission has successfully executed their first extravehicular activity outside the Tiangong space station. The operation, which lasted approximately eight hours, represents the 25th spacewalk conducted by Chinese taikonauts since the nation began its manned spaceflight endeavors.
Mission Commander Senior Colonel Zhang Lu and Spaceflight Engineer Major Wu Fei ventured into the vacuum of space at 11:45 AM Beijing Time on Tuesday, while Payload Specialist Zhang Hongzhang provided crucial support from within the station’s pressurized modules. The astronauts worked in concert with ground control teams and utilized the station’s sophisticated robotic arm to complete a series of complex tasks.
The primary objective involved the installation of enhanced protective shielding designed to mitigate risks from space debris impacts—a growing concern in increasingly congested orbital pathways. Additionally, the team replaced aging external instruments with upgraded scientific equipment and conducted thorough inspections of the station’s exterior components.
Of particular significance was their examination of the Shenzhou XX spacecraft’s reentry capsule, specifically documenting damage sustained by one of its windows from a micro-debris strike. This previously undisclosed incident had reportedly delayed the return of the previous crew, highlighting the very real dangers posed by orbital debris.
Notably, 32-year-old Major Wu Fei made history as the youngest Chinese astronaut to perform a spacewalk, surpassing the previous record held by 34-year-old Lieutenant Colonel Tang Shengjie.
The current mission marks China’s 16th manned spaceflight and the 10th expedition crew to inhabit Tiangong—presently the only space station operated independently by a single nation. Having resided aboard the orbital complex for nearly 40 days since their November 1 arrival, the crew has conducted extensive system checks, emergency preparedness drills, and robotic arm operations.
Future mission activities may include additional spacewalks and potential repairs to the damaged Shenzhou XX spacecraft viewport, contingent upon technical feasibility and mission priorities.
