During last week’s 6.5-hour spacewalk, China’s Shenzhou-20 astronauts completed vital inspections and installed protective equipment on the country’s space station.
The spacewalk, which took place Friday, represented the Shenzhou-20 crew’s third series of extravehicular activities since boarding the space station.
According to the China Manned Space Agency (CMSA), crew members Chen Dong, Chen Zhongrui, and Wang Jie worked for approximately six-and-a-half hours and completed all related tasks, assisted by the space station’s robotic arm and a ground control team.
Inside the station’s Tianhe core module, Chen Zhongrui provided vital support.

Debris protection measures
“The main goal of this spacewalk was to identify thermal characteristics of key external equipment and critical components. This allows us to better understand their operational conditions and collect detailed data, which also supports future spacecraft design and advancing our thermal control technologies,” Liang Xiaofeng, an engineer with the China Aerospace Science and Technology Corporation, told China Central Television (CCTV).
The spacewalk involved installation of debris protection measures and auxiliary structural components, as well as inspection of external equipment and systems on the station’s exterior.
The Shenzhou-20 trio entered the Tiangong space station on April 25 this year. They have now completed half of their spaceflight journey.
