Video: ESA train Astronauts for space walks by going climbing in caves


Why is living and working underground in a cave similar to being in space? Experienced spacewalkers and astronauts from ESA's underground training course CAVES explain how climbing down a cavern is not unlike spacewalking across the International Space Station. ESA astronaut Paolo Nespoli, Canadian Space Agency astronaut Jeremy Hansen, NASA astronauts Jack Fischer and Mike Barratt recount their experience of spending a week hundreds of metres underground.
