China's in-orbit Shenzhou-20 crew successfully completed their fourth round of extravehicular activities (EVAs) on Friday, according to the China Manned Space Agency (CMSA).

The crew trio, consisting of commander Chen Dong and taikonauts Chen Zhongrui and Wang Jie, successfully completed their assigned tasks at 1:35 a.m. Beijing Time after about six hours of coordinated work, with support from the space station's robotic arm and the ground control team, the CMSA said.

During the extravehicular activities, taikonauts Chen Zhongrui and Wang Jie completed tasks including installing debris protection devices for the space station and inspecting external equipment and facilities. It marked the first time that two members of China's third batch of taikonauts jointly carried out an EVA.

So far, the Shenzhou-20 crew has completed four EVAs, making them one of the Chinese crews with the most extravehicular missions.

The crew has been in orbit for more than 150 days and will continue their mission with extensive scientific experiments and technical tests. They are also set to celebrate the National Day and Mid-Autumn Festival aboard the space station.
