Astronauts conduct spacewalk to affix new ‘hands’ onto the Canadarm

Flight Engineers Mark Vande Hei of NASA and Norishige Kanai of the Japan Aerospace Exploration Agency spent six hours outside the International Space Station on Friday, February 16, performing maintenance work on the station’s robotic arms. The two astronauts removed two of Canadarm2’s “hands,” one for storage and the second to be shipped back to earth for refurbishing.
