Chinese astronauts aboard the Shenzhou-21 mission have successfully completed their second extravehicular activity (EVA) this week, marking another milestone in China's expanding space station operations. The seven-hour spacewalk on March 16 saw the crew install critical debris protection equipment and conduct system maintenance using the station's robotic arm, with real-time support from mission control engineers.
This achievement follows the crew's first EVA earlier this month and demonstrates growing operational efficiency in China's orbital program. The newly installed anti-debris system addresses increasing concerns about space traffic management as more nations deploy satellites and spacecraft.
With the Tiangong space station now fully operational since 2023, China has conducted 14 crewed spacewalks to date. The current mission underscores Beijing's commitment to maintaining a permanent human presence in low-Earth orbit while advancing technological capabilities for future lunar exploration projects planned through 2030.
