The Shenzhou-21 crew aboard China's orbiting space station completed their mission's third series of extravehicular activities (EVAs) on Friday, according to the China Manned Space Agency (CMSA).

The astronaut trio – Zhang Lu, Wu Fei and Zhang Hongzhang – worked for roughly five and a half hours and completed their tasks at 1:36 a.m. (Beijing Time), assisted by the space station's robotic arm and a team on Earth.

Zhang Lu has so far carried out seven EVAs, making him one of the Chinese astronauts with the most spacewalks to date.
