Attendees at China’s first international conference on space habitation and exploitation were given a tour of a vast underground cave system that Chinese researchers are hoping to use as a testing ground for living on the moon and Mars.

Xie Gengxin, from the Centre of Space Exploration at Chongqing University in southwestern China, organised the visit to Youyang Base, where large-scale closed cave ecosystem validation research is under way.
