Expedition 61 Commander Luca Parmitano of ESA (European Space Agency) and NASA Flight Engineer Andrew Morgan concluded their spacewalk at 12:33 p.m. EST. During the six hour and two minute spacewalk, the two astronauts successfully installed a new cooling system for the Alpha Magnetic Spectrometer (AMS).

The crew completed the primary task to install the upgraded cooling system, called the upgraded tracker thermal pump system (UTTPS), completed the power and data cable connection for the system, and connected all eight cooling lines from the AMS to the new system. The intricate connection work required making a clean cut for each existing stainless steel tube connected to the AMS then connecting it to the new system through a process of metalworking known as swaging.

The astronauts also completed an additional task to install an insulating blanket on the nadir side of the AMS to replace the heat shield and blanket they removed during the first spacewalk to begin the repair work. The flight control team on Earth initiated power-up of the system and confirmed it is receiving power and data.

It is the first long day of a very busy several weeks for the space station crew, with two cargo resupply spacecraft launching to the station loaded with science investigations; a SpaceX Dragon is scheduled to lift off at 12:51 p.m. Wednesday, and a Russian Progress is set to launch Friday at 4:34 a.m. Crew members then will be focused on the spacecrafts’ arrivals and associated work. Meanwhile, teams on Earth will evaluate the date for the planned fourth spacewalk to conduct leak checks for the spectrometer’s refurbished cooling lines and complete the work to resume operations of the cosmic ray detector.

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

Parmitano has now conducted five spacewalks in his career for a total of 26 hours and 53 minutes, and Morgan has logged 39 hours and 32 minutes during six spacewalks since his arrival on the station in July. It was the 11th spacewalk at the station this year. Space station crew members have conducted a total of 224 spacewalks in support of assembly and maintenance of the orbiting laboratory. Spacewalkers have now spent a total of 58 days 15 hours and 43 minutes working outside the station.
