Expedition 33 Commander Suni Williams and Flight Engineer Aki Hoshide completed a 6-hour, 38-minute spacewalk Thursday, wrapping it up it at 3:07 p.m. EDT. During the spacewalk, which began at 8:29 a.m., Williams and Hoshide ventured out to the port side of the International Space Station’s truss to configure the 2B solar array power channel’s photovoltaic thermal control system (PVTCS) to support ground-based troubleshooting of an ammonia leak. Over the following weeks and months, flight controllers at Mission Control Houston will monitor telemetry to see if the leak continues. This was the 166th spacewalk in support of station assembly, totaling 1,049 hours and 1 minute, the equivalent of 44 days. (Image Credit: NASA)
