Astronauts Complete Intricate Tasks During Second Cosmic Repair Spacewalk

Spacewalker Luca Parmitano is guided on the Canadarm2 robotic arm toward the work site on the Alpha Magnetic Spectrometer, the space station’s cosmic particle detector.

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.

  1. I’m very happy to be able to watch and learn about the intricate work going on up there in repairing this instrument. It may provide information that we can only wonder about at this point. My admiration goes out to all the people involved in exploring space as well as all fields of scientific endeavor. You are all my heros.

  2. Hello there. I would work on the world’s largest under water diving vessel in the world as a rigger in the Arabian Sea. So I do relate in a few ways to what you guys are doing out there. Love to all of you.
