This footage was taken during a spacewalk (EVA) on the International Space Station on March 1, 2015.
Two astronauts routed 400 feet of cable and installed several antennas associated with the Common Communications for Visiting Vehicles system known as C2V2. Boeing’s Crew Transportation System (CST)-100 and the SpaceX Crew Dragon will use the system in the coming years to rendezvous with the orbital laboratory and deliver crews to the space station.
