Chinese astronaut Ye Guangfu(L3)takes part in the European Space Agency (ESA) training program in the rocky caves of Sardinia, Italy. The other five participants are ESA astronaut Pedro Duque, NASA astronauts Jessica Meir and Richard Arnold, Japanese astronaut Aki Hoshide and cosmonaut Sergei Korsakov. In the dark underground caves, the space explorers will test their ability to survive without natural light and the sounds that are so familiar to surface dwellers.
