As was the case during the first Shenzhou-13 spacewalk on 7 November, two crew members will exit the spacecraft while another one will be coordinating their work from inside.
The current crew includes commander Zhai Zhigang and first-time mission astronaut Ye Guangfu, as well as Wang Yaping, the first female astronaut to board the Chinese orbital station. They have been at Tiangong since 16 October for a six-month mission.
China began building its own space station in April. Construction works are scheduled to end in 2022.
