Chinese astronauts climbed into space Friday to finish a robotic arm for the Tiangong space station.
This foray is the second spacewalk in as many months. It was broadcast on state television.
Three crew members arrived at the station in June. They will remain there for three months, making it China's longest-ever crewed mission.
China Manned Space Agency released a statement saying that Nie Haisheng (astronaut) and Liu Boming (astronaut) successfully exited Tianhe's core module to install footstops and a workbench for the station's robotic arm.
The astronauts were seen working outside the spacecraft with a long rope attached to their bodies.
According to state broadcaster CCTV, their tasks include adjusting a panoramic camera and setting up a thermal unit.
After the 2008 spacewalk, Zhai Zhigang made China third country to successfully complete a spacewalk.
