At 12:25 a.m. EST, the crew opened the first window shutter of the cupola.
At this point into today’s spacewalk, Robert Behnken and Nicholas Patrick will come back together to route cables for the station’s video signal converter, or VSC. The VSC is used with power and data grapple fixtures, of PDGFs, which provide locations on the exterior of the station’s modules for the station’s robotic arm to attach to.
Behnken and Patrick will wrap up the last of the spacewalk activities for the mission with two final tasks. First, they will close off the centerline camera that was used on the zenith, or space-facing, port of the Harmony node when the pressurized mating adapter 3 was attached it. And finally, they will each remove six clamps and the flex hose rotary coupler on the port 1 segment of the station’s truss.
