The crew of China’s orbiting space station has completed the first of several planned spacewalks in their six-month mission.
The China Manned Space Agency said Fei Junlong and Zhang Lu carried out a number of tasks during Friday’s seven-hour extra-vehicular activity, including installing extension pumps outside the Mengtian laboratory module.
The third member of the Shenzhou-15 mission, Deng Qingming, assisted from inside the station. The three are scheduled to carry out several other spacewalks during their time on board.
China completed the Tiangong station in November with the addition of the third of three modules, centred on the Tianhe living and command module.
China built its own station after it was excluded from the International Space Station, largely due to US objections over the Chinese space programme’s intimate ties to the People’s Liberation Army, the military wing of the ruling Communist Party.

International security concerns around China were underlined last week when the US military shot down an alleged Chinese military spy balloon that had drifted across the continental United States.
China has maintained it was a civilian weather balloon that blew off course.
Tiangong weighs about 66 tonnes – a fraction of the 465-tonne International Space Station. It can accommodate up to six astronauts, though only three will be on board for each mission.
With a lifespan of 10 to 15 years, Tiangong could one day be the only space station still up and running if the ISS retires around the end of the decade, as expected.
China in 2003 became the third government to send an astronaut into orbit on its own after the former Soviet Union and the United States.
It conducted its first spacewalk in September 2008 and the tempo of such activities has increased since the launch of the Tianhe module in 2021.
The country has also chalked up uncrewed mission successes. Its Yutu-2 rover was the first to explore the little-known far side of the moon.
The Chang’e 5 probe also returned lunar rocks to Earth in December 2020 for the first time since the 1970s, and another Chinese rover is searching for evidence of life on Mars.
An eventual crewed mission to the moon is also under consideration, although no timeline has been offered.
