In a groundbreaking program, 28 Chinese astronauts have successfully completed the nation’s first-ever cave survival training in Wulong, Chongqing. During the intense six-day mission conducted in near-total darkness, with 99% humidity and an average temperature of 8°C, the team navigated narrow passages, scaled cliffs, and conducted scientific tasks. Officials from the China Manned Space Agency stated the training aimed to greatly improve resilience, teamwork, and emergency decision-making in extreme isolation, simulating deep-space exploration challenges. This rigorous exercise provides critical preparation for future long-duration space station missions and crewed lunar expeditions.
