Two Chinese astronauts aboard the Tiangong space station have broken the world record for the longest single spacewalk, set more than two decades ago by the US space programme.
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).
