S100-E-5076 (21 April 2001) --- Not far away from his extravehicular mobility unit (EMU) space suit on Endeavour's middeck and not far away in time (less than a day) from a scheduled space walk, it's a relatively sure bet that astronaut Chris A. Hadfield, mission specialist representing the Canadian Space Agency (CSA), is thinking about extravehicular activity (EVA). The photo was recorded with a digital still camera.
