Video: Astronauts on spacewalk replace balky relay box outside the ISS

On Wednesday at the International Space Station:

… Expedition 39 Flight Engineers Rick Mastracchio and Steve Swanson of NASA conducted a spacewalk April 23 to replace a backup computer relay box on the station’s S0 (s-zero) truss.
