The Shenzhou-21 crew has marked another milestone in China's space exploration program, completing their third spacewalk this week aboard the Tiangong space station. Astronauts Zhang Lu, Wu Fei, and Zhang Hongzhang concluded the 5.5-hour extravehicular activity (EVA) early Friday, demonstrating China's growing technical prowess in orbital operations.
Working in precise coordination with ground control teams and utilizing the station's robotic arm, the crew successfully installed advanced space debris shielding and conducted critical maintenance checks. This achievement comes as mission controllers announced a one-month extension of the crew's orbital stay to conduct additional scientific experiments.
Veteran astronaut Zhang Lu has now completed seven career spacewalks – a new national record that underscores China's expanding human spaceflight capabilities. The current mission continues China's pattern of steady progress in space station operations, with 14 successful EVAs conducted since the station's initial assembly phase began in 2021.
The extended mission timeline will enable researchers to collect long-term microgravity data and test new life support systems. These developments hold particular significance for international partners considering collaboration opportunities aboard the station, which Chinese officials have emphasized will remain open to global scientific projects through 2032.
