HOUSTON (NASA PR) — Expedition 61 Commander Luca Parmitano of ESA (European Space Agency) and NASA Flight Engineer Andrew Morgan concluded their spacewalk at 1:35 p.m. EST. During the six-hour and 33-minute spacewalk, the two astronauts successfully cut a total of eight stainless steel tubes, including one that vented the remaining carbon dioxide from the old cooling pump on the Alpha Magnetic Spectrometer (AMS). The crew members also prepared a power cable and installed a mechanical attachment device in advance of installing the new cooling system.
Today’s work clears the way for Parmitano and Morgan’s next spacewalk in the repair series Monday Dec. 2. The plan is to bypass the old thermal control system by attaching a new one off the side of AMS during the third spacewalk, and then conduct leak checks on a fourth spacewalk.

Space station crew members have conducted 223 spacewalks in support of assembly and maintenance of the orbiting laboratory. Spacewalkers have now spent a total of 58 days 9 hours and 41 minutes working outside the station. Parmitano has now conducted three spacewalks in his career and Morgan has now logged four spacewalks since his arrival on the station in July.
