The CAVES 2013 team is introduced to the caves of Sardinia and learns about exploration and orientation.

CAVES, ESA's unique training programme for astronauts, takes place over a couple of weeks in Sardinia's Supramonte. Six astronauts spend two weeks deep in caves, in the dark and cold. They are separated from the outside world, doing scientific research and daily tasks together, as a group, just like in space. Moving in the cave system is also comparable to spacewalking with the use of harnesses and safety devices.
