313 DAY IN THE LIFE: RISKY AND REWARDING SPACEWALKS—SPACE SHUTTLE MISSION STS-120/ISS-10A CHAPTER 18 contaminate the ISS atmosphere. The Node 2 module was robotically moved out of the shuttle payload bay to its temporary location on the port side of Node 1. Applause erupted in the engineering room over this important new module for the ISS. The day between EVAs 1 and 2 was spent preparing the suits and tools for the next EVA. This day also allowed time for the flight control team to get information to the crew members about their new task to inspect the SARJ and for the crew members to study the slightly altered choreography for the EVA. Flight Days 6-7 (Sunday, October 28 and Monday, October 29) The flight control team had its hands full of small EVA surprises during the second spacewalk on October 28. Detaching the P6 truss segment went well, but some of the shorter planned tasks had to be cancelled (i.e., put into later EVAs) due to the issues encountered throughout the day. For example, the display locked up on Tani’s spacesuit, and he had to perform a “reboot,” as one would with a locked-up computer display. Also, the crew had difficulty operating some of the connectors, small o-rings floated out of some of the connectors, and a pin dislodged and couldn’t be extracted from an area at a Node 2 berthing mechanism. Figure 7. Photos of tape that the EVA 2 crew used to pick up metal particles seen on the SARJ. The tape was initially adhered to a caddy (top photo) that resembled a book with slick paper. The crew peeled the tape off of the caddy and made a loop with the sticky side out to pat the area and pick up the particles (bottom photo). The tape was put into a bag that came back down to the ground on the shuttle. The starboard SARJ inspection revealed major news that would heavily affect the next few days. When Tani removed the cover, he saw what appeared to be magnetized metal shavings on the passive ring of the SARJ (Figure 7). Shavings indicated pieces of the joint were grinding so hard that small metal pieces, also known as Foreign Object Debris, were coming off and creating some amount of permanent damage. Tani’s electronic still camera was not working, so the ground sent Parazynski to retrieve
