The primary task during the five-hour, 51-minute excursion was to move the Strela-2 cargo boom from the Pirs docking compartment to the Zarya module. The move was another step in preparing Pirs for its eventual undocking and disposal, which will make room for the docking of the new Russian multipurpose laboratory module to the Zvezda nadir port. Other tasks included the installation of micrometeoroid debris shields on the exterior of the Zvezda service module and the deployment of a small science satellite.
A second Expedition 32 spacewalk, scheduled for Aug. 30, will be conducted by NASA Flight Engineer Sunita Williams and Japan Aerospace Exploration Agency Flight Engineer Akihiko Hoshide. The duo will don U.S. extravehicular mobility unit spacesuits for the first U.S.-based spacewalk since July 2011. It will be a 6.5-hour excursion designed to replace a faulty power relay unit on the station’s truss, rig power cables for the arrival late next year of a Russian laboratory module, replace a failing robotic arm camera and install a thermal cover on a docking port.
