Members of the Shenzhou-19 crew aboard China's orbiting space station completed the second series of their mission's extravehicular activities at 1:12 a.m. on Tuesday, according to the China Manned Space Agency.

Astronauts Cai Xuzhe, Song Lingdong and Wang Haoze worked for 8.5 hours to complete multiple tasks, including the installation of space debris protection devices and an extravehicular inspection.

Cai and Song, the two crew members assigned to undertake spacewalk duties, have since returned safely to the Wentian lab module.
