Two astronauts have completed their fifth and final spacewalk installing two cameras on Japan's Kibo laboratory at the International Space Station (ISS), the US space agency NASA said.
The spacewalk, conducted by Chris Cassidy and Tom Marshburn, lasted four hours and 54 minutes.
The astronauts performed an electrical cable swap and adjustment of insulation blankets on the Special Purpose Dexterous Manipulator.
They also performed a number of other tasks, including tying down some cables and installing handrails and a portable foot restraint to aid future spacewalkers, NASA said Monday.
The deployment of the Payload Attach System on the Starboard 3 truss was deferred to another spacewalk sometime in the future. Astronauts also replaced six batteries for the ISS.
The astronauts will return to earth July 31 on board the Endeavour space shuttle.
