Another kind of "dark room"

2013-09-18 - CSA astronaut Jeremy Hansen and fellow cavenauts learn to take photographs in the darkness of a cave. From September 16 to 27, 2013, CSA astronaut Jeremy Hansen takes part in the European Space Agency’s CAVES 2013 training expedition. CAVES (or Cooperative Adventure for Valuing and Exercising human behaviour and performance Skills) is an opportunity for Hansen and five other astronauts to get advanced experience on Earth in some of the situations they'll face during the extremes of a long-duration space mission.
