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. 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.

For more on the AMS science and spacewalks, listen to the recent podcasts:

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.

Expedition 61 Commander Luca Parmitano of ESA (European Space Agency) and NASA Flight Engineer Andrew Morgan concluded their spacewalk at 1:18 p.m. EST. During the six hour and 39 minute spacewalk, the two astronauts successfully positioned materials, removed a debris cover on the AMS, and installed handrails in preparation for the subsequent spacewalks.

The duo also completed a number of get-ahead tasks originally planned for the second spacewalk, including the removal of the vertical support beam cover for the area that houses the eight stainless steel tubes that will be cut and spliced together on the upcoming spacewalks.

Today’s work clears the way for Parmitano and Morgan’s next spacewalk in the repair series Friday Nov. 22. The main focus of the second spacewalk will be the access, cut, and label the stainless steel tubes that attach the current cooling system to the AMS. The plan is to bypass the old thermal control system, attach a new one off the side of AMS during the third spacewalk, and then conduct leak checks.

In addition to the overall complexity of the instrument, astronauts have never before cut and reconnected fluid lines, like those that are part of the AMS thermal control system, during a spacewalk. To cut the cooling lines and complete other tasks in this series of spacewalks, scientists, engineers and astronauts on Earth have gone through several iterations of designing, prototyping, experimenting and validating many specialized tools in preparation for the complex work in space.

Space station crew members have conducted 222 spacewalks in support of assembly and maintenance of the orbiting laboratory. Spacewalkers have now spent a total of 58 days 3 hours and 8 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.

Expedition 61 Commander Luca Parmitano of ESA (European Space Agency) and NASA Flight Engineer Andrew Morgan will begin a spacewalk outside of the International Space Station at about 7 a.m. EST Friday, Nov. 15. NASA Television coverage of the spacewalk will begin at 5:30 a.m.

Watch the spacewalk on NASA TV and on the agency’s website.

The two astronauts will venture outside the International Space Station for the first in a series of complex spacewalks to replace a cooling system on the Alpha Magnetic Spectrometer (AMS), a cosmic ray detector. The upgraded cooling system will support AMS through the lifetime of the space station.

Parmitano and Morgan have spent dozens of hours training specifically for the AMS repair spacewalks. NASA astronauts Christina Koch and Jessica Meir will help Parmitano and Morgan suit up for the spacewalks and will maneuver the Canadarm2 robotic arm to help position the spacewalkers around the AMS repair worksite.

These spacewalks are considered the most complex of their kind since the Hubble Space Telescope servicing missions. The AMS originally was designed for a three-year mission and, unlike Hubble, was not designed to be serviced once in space. More than 20 unique tools were designed for the intricate repair work, which will include the cutting and splicing of eight cooling tubes to be connected to the new system, and reconnection of a myriad of power and data cables. In addition to the overall complexity, astronauts have never before cut and reconnected fluid lines, like those that are part of the cooling system, during a spacewalk.
