Crew members aboard China's orbiting space station completed their first spacewalk as part of their six-month mission. The seven-hour extra-vehicular activity was completed at 12:16 a.m. Fei Junlong and Zhang Lu, who are members of the Shenzhou-15 mission, completed several tasks like installing extension pumps outside the Mengtian laboratory module during the spacewalk while fellow crew member Deng Qingming supported them from inside the Tiangong space station, according to AP News. Fei and Zhang safely returned to the Wentian lab module following the extravehicular activity, according to China.org.cn. The three crew members are expected to make several such spacewalks while aboard the Tiangong station, which is the second permanently inhabited space outpost after Nasa's International Space Station.
