BEIJING, March 16 (Xinhua) -- The Shenzhou-21 crew aboard China's orbiting space station completed their mission's second series of extravehicular activities (EVAs) on Monday, according to the China Manned Space Agency.

The astronaut trio -- Zhang Lu, Wu Fei and Zhang Hongzhang -- worked for roughly seven hours and completed their tasks at 7:35 p.m. (Beijing Time), assisted by the space station's robotic arm and a team on Earth.

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