Suni Williams and Aki Hoshide successfully completed the installation of a Main Bus Switching Unit (MBSU) that was hampered last week by a possible misalignment and damaged bolt threads.
"Everyone on the ground, great job," Hoshide said as he completed driving the bolt. "The MBSU is locked."
"That is a little slice of awesome pie," capcom Jack Fischer replied from Mission Control in Houston.
Williams and Hoshide used improvised tools, including a bristle and toothbrush, to troubleshoot the installation. The tools were used to clean the bolts and receptacles and clear the area of any debris.
The two spacewalkers also installed a camera on the space station's robotic arm, Canadarm2.
The spacewalk, which lasted 6 hours and 28 minutes, ended at 12:34 p.m. CDT Wednesday (Sept. 5). During the spacewalk,
Williams set a new record for the total cumulative time spacewalking by a woman.
