Astronauts spacewalk to install new camera system on ISS

Two NASA astronauts have successfully completed a spacewalk to install a new camera system outside the International Space Station (ISS), replacing a blown fuse and installing a new high definition camera on the starboard truss of the station.

During the spacewalk, which lasted six hours and 49 minutes, the duo of Randy Bresnik, Expedition 53 Commander and Joe Acaba, Flight Engineer at NASA worked quickly and were able to complete several "get ahead" tasks, Melanie Whiting from NASA wrote in a blogpost.

Acaba greased the new end effector on the robotic arm. Bresnik installed a new radiator grapple bar and completed prep work for one of two spare pump modules on separate stowage platforms to enable easier access for potential robotic replacement tasks in the future.

"He nearly finished prep work on the second, but that work will be completed by future spacewalkers," Whiting said.

This was the fifth spacewalk of Bresnik's career - 32 hours total spacewalking - and the third for Acaba - 19 hours and 46 minutes total spacewalking.

Space station crew members have conducted 205 spacewalks in support of assembly and maintenance of the orbiting laboratory. Spacewalkers have now spent a total of 53 days, six hours and 25 minutes working outside the station.
