Chinese astronauts complete world record-breaking spacewalk at 9 hours

At 9.57pm Beijing time on Tuesday, Shenzhou-19 crew members Cai Xuzhe and Song Lingdong completed a nine-hour extravehicular activity (EVA), according to the China Manned Space Agency (CMSA).

The previous record was set on March 11, 2001, when American astronauts James Voss and Susan Helms spent eight hours and 56 minutes outside the space shuttle Discovery during a mission to the International Space Station, according to Nasa.

The nine-hour EVA also marks a milestone in China’s spacewalk history. Earlier this year, Shenzhou-18 astronauts Ye Guangfu and Li Guangsu completed a similar mission, spending eight hours and 23 minutes outside Tiangong.

State broadcaster CCTV reported at the time that the second-generation “Feitian” spacesuits worn by the astronauts during the EVA in May were capable of supporting up to eight hours of external work – double the duration of the first-generation suits.

China’s first-ever spacewalk occurred in September 2008, when Zhai Zhigang spent just under 20 minutes outside the Shenzhou-7 spacecraft in the first-generation Feitian suit.
