Expedition 48 Commander Jeff Williams and Flight Engineer Kate Rubins of NASA will begin a spacewalk outside of the International Space Station at about 8:10 a.m. EDT Thursday. NASA TV coverage will begin at 6:30 a.m.
Williams and Rubins will retract a thermal radiator that is part of the station’s cooling system. The radiator is a backup that had been deployed previously as part of an effort to fix an ammonia coolant leak. They’ll also tighten struts on a solar array joint, and install the first of several enhanced high-definition television cameras that will be used to monitor activities outside the station, including the comings and goings of visiting cargo and crew vehicles.
