Beijing: The crew of China's Shenzhou-20 aboard the country's orbiting space station successfully completed their second extravehicular activity (EVA), the China Manned Space Agency (CMSA) announced on Thursday.

According to Anadolu Agency, astronauts Chen Dong, Chen Zhongrui, and Wang Jie worked for approximately 6.5 hours, completing the task at 9:29 pm (0129GMT), Xinhua News Agency reported, citing the CMSA. They were assisted by the space station's robotic arm and a team on Earth.

Chen Dong and Chen Zhongrui conducted spacewalk operations, installing a debris protection device and performing inspection and maintenance of external equipment, as reported by the agency. These operations included attaching foot restraints and interface adapters to the extravehicular platform, improvements that are expected to reduce the duration of future spacewalks by around 40 minutes, according to CMSA.

Meanwhile, the crew continues to make steady progress on a range of scientific tasks. Their upcoming work includes experiments and technology demonstrations in critical fields such as space life sciences, microgravity physics, space materials, space medicine, and advanced aerospace engineering, said CMSA.

The three astronauts aboard China's Shenzhou-20 spaceship successfully entered the Tiangong space station on April 25.
