The Shenzhou-18 crew aboard China's orbiting space station successfully completed multiple tasks in their second spacewalk on Wednesday, according to the China Manned Space Agency.
The mission, which lasted about six and a half hours, was conducted by the trio, Ye Guangfu, Li Cong and Li Guangsu, with the assistance of a ground team and the space station's robotic arm.
At 16:19, Li Cong opened the hatch door of the Wentian space lab module and began his first spacewalk.
With the assistance of the space station's robotic arm, Li came to the operation point. Then Ye Guangfu transferred the relevant equipment and devices out of the space station and exited the capsule at 17:41.
Ye climbed to the operation point by himself, and cooperated with Li to install protection devices for the cables of the Wentian lab module and the pipelines of the Tianhe core module.
In the meantime, Li Guangsu carried out monitoring of the robotic arm and provided necessary support from inside the Tianhe core module.
"The main purpose of the spacewalk this time is to install protection devices for extravehicular equipment, mainly cables and pipelines, so as to improve the space station's ability to operate safely and steadily over the long term," said Liu Ming, an engineer with the China Aerospace Science and Technology Corporation.
In their previous spacewalk on May 28, the Shenzhou-18 trio mainly installed protection devices for the extravehicular cables of the Mengtian lab module. The spacewalk this time is to install protection devices for the extravehicular cables and pipelines of the Wentian lab module and the Tianhe core module.
"There are more protection devices we have to install this time than the previous spacewalk. During the process, astronauts needed to get from the exit hatch to the relevant operation points, which took them a lot of time. But they have completed the task with ease," said Wu Dawei, an expert with the China Astronaut Research and Training Center.
After installing protection devices, Li Cong mounted the robotic arm and conducted an extravehicular inspection of the space station's facilities through his helmet camera.
"The astronauts completed the extravehicular mission with great ease and in a smooth and perfect way," said Wu.
After completing the predetermined tasks, Ye Guangfu and Li Cong returned safely to the Wentian lab module.
"The Chinese space station is very beautiful. Whenever the robotic arm moves to the highest point, I can't help taking more glances at the space station despite the glaring sunlight. I really feel the greatness of the project from my heart, and I applaud all the space professionals and our motherland. We will make continuous efforts to successfully and efficiently complete the follow-up tasks to the end. Let's meet again inside the cabin," Li Cong said outside the space station.
"Congratulations to the Shenzhou-18 crew on the successful completion of the extravehicular mission. We are very lucky to have you on the space station and we look forward to more of your wonderful performances in the following tasks," a ground staff member replied at the Beijing Aerospace Control Center.
The Shenzhou-18 crew, sent to the space on April 25 this year, have completed one third of their space journey and are scheduled to carry out a large amount of in-orbit scientific experiments and technological tests, the agency said.
