During Monday's 4-hour, 54-minute spacewalk, astronauts Tom Marshburn (left) and Christopher Cassidy secured multi-layer insulation around the Special Purpose Dexterous Manipulator known as Dextre, split out power channels for two space station Control Moment Gyroscopes, installed video cameras on the front and back of the new Japanese Exposed Facility and performed a number of get ahead tasks, including tying down some cables and installing handrails and a portable foot restraint to aid future spacewalkers. The spacewalk on July 27, 2009, was the fifth and final spacewalk for the STS-127 mission.
