Shenzhou XII astronauts conduct second spacewalk

Pang Zhihao, a space industry observer and retired researcher at the China Academy of Space Technology, said that Chinese astronauts have become skilled in extravehicular maneuvers despite having done only three spacewalks so far.

"You can see through the video clips published by the agency that Nie and Liu carried out their tasks expertly and they seemed to be quite relaxed. I think that is why they could finish the operation earlier than planned," he said.

Pang added that the impressive photos they took during the spacewalk will inspire more young people to know about or even take part in China's space endeavors.
