371 DAY IN THE LIFE: WHEN MAJOR ANOMALIES OCCUR CHAPTER 20 should be done in the airlock to check for ammonia, due to the small quantity of flakes, length of time the ammonia had been “baking off” the spacesuit, and history with these test results in similar conditions. Figure 12. The ISS flight controllers during the first spacewalk to repair the faulty Pump Module. From Left to right: videographer, Flight Director Dina Contella, CAPCOMs Aki Hoshide and Doug Wheelock, and Lead U.S. EVA Officer Allison Bolinger. The spacesuits generally performed well however, at one point, Hopkins noted that some of the outer layer of material was missing from his left glove (see also Figure 6, Chapter 17). The ground team discussed the situation and the Flight Rules that govern glove damage and decided that the EVA could continue because the underlying bladder-protecting material had not been damaged. The outer layer was for better grip of the tools and handrails, but the parts of the suit that held its shape and kept oxygen from leaking out were still intact. The ISS also happened to experience some unrelated failures during the EVA. For instance, a smoke alarm rang on board the ISS. The ground team and crew had to quickly re- prioritize what they were working on so that a potential fire could be discussed. The EVA crew members and their work were frankly lower priority than any possible fire. However, this smoke alarm was determined to be a false smoke indication in the Service Module. The smoke detector was set off when the crew kicked up some dust while cleaning. Another unrelated failure occurred with the Carbon Dioxide Removal Assembly, which had to be manually restarted by ground command after a failure. These sorts of surprises kept the flight control team on edge. Thanks to similar training during simulations and similar failures seen in the past, the team was able to work through them fairly quickly and continue the spacewalk. The entire team, including the seasoned crew, did very well that day, and there was time to pull the degraded Pump Module out of the truss and temporarily stow it in a designated location on the Mobile
