Chris Cassidy and Tom Marshburn floated out of the ISS about an hour earlier than planned at 11.33 GMT (about 7.30 pm Beijing time) as they began the mission's fifth spacewalk, which was expected to last six-and-a-half hours.

While Mashburn secures multi-layer insulation around the station's two-armed robot, the Special Purpose Dexterous Manipulator known as DEXTRE, Cassidy will separate the power channels shared by two of the station's four gyroscopes.

The spacewalking duo will then install video cameras on the front and back of Japan's Kibo laboratory, which became the station's biggest room when it was installed last year.

For their final task, the astronauts will deploy a payload on another part of the ISS that will provide storage capability for spare space station hardware.
