    Astronauts Use Wentian Laboratory Airlock Cabin for the First Time on 88th Day in SpaceChinese Astronauts of Shenzhou XIV Mission Started to conduct their first spacewalk, also known as an extravehicular activity, which is expected to end early Friday morning, according to the China Manned Space Agency. Mission Commander Senior Col. Chen Dong opened an extravehicular activity hatch on the Tiangong space station at 6:26 p.m. Thursday Beijing time and then floated out of the station. He was followed by Senior Colonel Liu Yang, a female crew member, the agency said in a press release. This was the first spacewalk ever for Chen and Liu, who are both on their second space trip.The other team member, Senior Colonel Cai Xuzhe, remained inside the station to support their operations, according to the statement. Chen and Liu were tasked with using a robotic arm to install new instruments outside the station. Tiangong, set panoramic camera and other operations. The two were expected to remain outside for about seven hours, according to the agency.This was the first time astronauts had used the airlock cabin at Wentian’s space lab to prepare and then perform a spacewalk. space.Crew members of previous flights have used the airlock cabin on the Tianhe core module to support spacewalks.With the new cabin, Tianhe’s is become the back-up carrier for future spacewalks.Zhang Qiao, chief designer of Wentian’s overall structure at the Chinese Academy of Space Technology, said the interior space of the new cabin is larger than that of the Tianhe module, and its hatch is wider, making it easier for astronauts to prepare and carry spacewalks.The spacewalk also marks the first times that a new type of tie line and a new system of external lighting have been used on the Chinese space station.Pang Zhihao, a renowned observer of China‘s human spaceflight, said the astronauts will check whether the new airlock cabin works well to support spacewalks. space. “It must be more comfortable and convenient for astronauts to use the new cabin for their spacewalk because the section has been specially designed to support extravehicular activities”, he said .”As soon as the astronauts opened the hatch, they must have seen the beautiful scenes of the mother planet, because the hatch is still facing Earth,” Pang said.Pang, who was a senior researcher at the Chinese Academy of Space Technology, said the spacewalk was also meant to demonstrate the capabilities of the Wentian lab’s robotic arm.Chen and his teammates spent 88 days in orbit on Thursday and performed a series of tasks such s that arranging cargo, testing equipment and conducting scientific experiments, the space agency said.The crew arrived in Tiangong on the evening of June 5, several hours after launching their spacecraft from the Jiuquan Satellite Launch Center in the northwest Gobi Desert.They are to remain at the station, orbiting 400 kilometers above Earth, for six months to oversee the planned assembly of the colossal outpost.Shenzhou XIV is the sixth spacecraft to visit Tiangong and the third crewed ship to transport astronauts to the station.Currently, Tiangong includes the Tianhe core module, the Tianzhou 4 cargo ship, the Shenzhou XIV spacecraft and the Wentian space laboratory, which was launched in late July.Mission planners said that the second component of the Tiangong laboratory, Mengtian, will be lifted by a carrier rocket Long 5B walk from Wenchang Space Launch Center in Hainan Province in October. After Mengtian is connected to Tiangong, the station will be a T-shaped structure. The whole station is expected to operate in orbit for 15 years old.
