The Shenzhou-17 crew members on board China's orbiting space station completed their first spacewalk at 9:35 p.m. (Beijing Time) on Thursday, according to the China Manned Space Agency. Tang Hongbo, Tang Shengjie and Jiang Xinlin worked seven-and-a-half hours to complete set tasks such as a Tianhe core module solar wing repair test, with the assistance of a ground team and the space station's robotic arm. It was the second time that Tang Hongbo, China's first space traveler to return to the space station for a second mission, has performed a spacewalk. Tang Shengjie became the country's youngest astronaut to carry out an extravehicular mission. (Photo by Han Qiyang/Xinhua)
