During the spacewalk, Hopkins and Glover will vent early ammonia system jumper cables and relocate one of them near the Quest airlock in order to reconnect the jumper cable to the current cooling system, increasing its efficiency. The duo also will connect cables for the Columbus Bartolomeo payload platform, continuing work from a Jan. 27 spacewalk, and replace a cable for an amateur radio system. Additionally, the astronauts will replace a wireless antenna assembly on the Unity module, install a “stiffener” on the airlock’s thermal cover to provide additional structural integrity, and route cables to provide ethernet capabilities for two high-definition cameras on the station’s port truss, or “backbone.”
