Successful Extravehicular Activities
On April 16, 2026, the crew of China's Shenzhou XXI mission successfully completed their third extravehicular activity (EVA) outside the Tiangong space station. Mission commander Senior Colonel Zhang Lu and spaceflight engineer Major Wu Fei conducted the approximately five-and-a-half-hour spacewalk, returning to the Wentian science module at 1:36 AM Beijing time. The third crew member, payload specialist Zhang Hongzhang, remained inside the station to provide support. The astronauts installed space debris protection devices and inspected external equipment, with assistance from ground controllers and the station's robotic arm.
This EVA marked the 27th conducted by Chinese astronauts and set a new record for Zhang Lu, who has now completed seven spacewalks, surpassing all other Chinese astronauts. The Shenzhou XXI crew has been aboard the Tiangong space station for over five months since their arrival on November 1, 2025.
Mission Extension and Future Plans
Following the successful completion of the spacewalk, the China Manned Space Agency (CMSA) announced an extension of the Shenzhou XXI mission by approximately one month. This decision aims to further validate technologies for long-duration manned spaceflights and to utilize supplies delivered by the Shenzhou XXII spacecraft, which was launched in late November 2025. The extended mission will allow the crew to continue conducting scientific experiments and technical tests in orbit.
The astronauts are expected to celebrate China Space Day on April 24 and International Workers' Day on May 1 while aboard the station. The Shenzhou XXI crew will ultimately return to Earth in the Shenzhou XXII spacecraft, likely around mid-to-late May 2026.
Ongoing Scientific Research
During their time aboard the Tiangong space station, the Shenzhou XXI crew has engaged in various scientific experiments related to space life sciences, human physiology, and microgravity physics. They have also performed routine operations, including environmental monitoring, equipment inspection, and maintenance. The astronauts completed a full-system pressure emergency response drill and emergency survival training, ensuring preparedness for any potential challenges during their extended stay.
Official Statements & Responses
The CMSA emphasized the importance of the Shenzhou XXI mission in advancing China's capabilities in human spaceflight and long-term habitation in orbit. The agency noted that the extension of the mission aligns with their goals of maximizing the benefits of the Shenzhou-22 spacecraft as an emergency return vehicle.
Criticism & Opposition
While the mission has been celebrated domestically, some critics have raised concerns about the sustainability of China's space program and the potential risks associated with extended missions. However, official statements from the CMSA maintain that the mission's objectives are crucial for the future of China's space exploration efforts.
