Chinese astronauts install tools during first spacewalk outside new space station


For the first time, two astronauts have worked outside the Chinese space station, completing only the second spacewalk in the history of the country’s space program.

Liu Boming and Tang Hongbo began the six-hour and 46-minute extravehicular activity (EVA) on Saturday, July 3 at 8:11 p.m. EDT (0011 GMT or 8:11 a.m. Beijing time on July 4). Liu was the first to leave the space station Tianhe Core Module (“Harmony of the Heavens”), followed by Tang about three hours later.

Wearing improved Chinese Feitian space suits, the two Shenzhou 12 teammates equipped the space station with the necessary tools to support future activities.

Liu, initially working alone, attached a footrest and platform to the end of the station’s 10-meter-long robotic arm, then mounted the arm himself. Shenzhou 12 commander Nie Haisheng then tested the arm controls, moving Liu from inside the Tianhe module.

Tang, attached to the handrails along the outside of the space station, then joined Liu to extend a panoramic camera. They then continued to work together to install other EVA equipment using the robotic arm.

“After about 7 hours of outdoor activities, the 12 Shenzhou teammates working closely together successfully completed all the tasks planned during the spacewalk,” the manned Chinese Space Agency announced at the end of the EVA.

Liu and Tang completed the spacewalk at 2:57 a.m. EDT (0657 GMT or 2:57 p.m. Beijing time) on Sunday.

A second spacewalk is planned later as part of the Shenzhou 12 mission, which launched with Nie, Liu and Tang June 16 and is expected to last three months. In addition to the test procedures, the EVAs are preparing the extension of the station with the addition of two laboratory modules which will be launched in 2022.

China’s very first spacewalk was carried out by Zhai Zhigang, commander of the Shenzhou 7 mission, in 2008. Liu was also on the mission’s crew, and during the 22-minute excursion, performed a standing EVA, popping its head out of the hatch while wearing a Russian Orlan spacesuit.

The Chinese Feitian (“flying to space”) suits are similar in design to the Orlan, with the portable survival system also serving as a rear entry hatch into the space suit. The Feitian’s helmets are fitted with cameras, broadcasting a first-person view similar to the space suit from NASA’s extravehicular activity unit (EMU).

When not on a spacewalk, Shenzhou 12 teammates configured and tested Tianhe central module systems, conducted science experiments, and participated in video downlinks, including chatting live with the president. Chinese Xi Jinping.

When completed, the T-shaped Tiangong (“Heavenly Palace”) space station will be China’s first multimodule space station. In addition to hosting Chinese crews and researchers, China plans to invite international partners to visit and work aboard the orbiting outpost.
