Two astronauts made the first space walk on Sunday outside China’s new orbital station to work on setting up a 15-meter (50-foot) long robotic arm.
Liu Boming and Tang Hongbo were shown by state TV climbing out of the airlock as Earth rolled past below them. The third crew member, Commander Nie Haisheng, stayed inside.Astronauts arrived June 17 for three-month mission aboard China’s third orbital station, part of an ambitious space program that landed a robot rover on Mars in May. Their mission comes as the ruling Communist Party celebrates the 100th anniversary of its founding.
The station’s first module, Tianhe, or Heavenly Harmony, was launched April 29. That was followed by an automated spacecraft with food and fuel. Liu, Nie and Tang arrived June 17 aboard a Shenzhou capsule.
