Spacewalks
Three spacewalks were conducted to replace six aging batteries and to stage spare components outside the station, including a secondary Ku band antenna and spares for the Canadian Dextre robotic arm extension.

| Reisman and Bowen installed a spare space-to-ground Ku band antenna on the station's truss, or backbone. They then installed a new tool platform on Dextre. The spacewalkers also broke the torque on bolts holding batteries in place on the truss, in preparation for their removal and replacement on the second and third spacewalks. | ||||

| Bowen and Good removed and replaced four of the six batteries on the port truss to store electricity from the solar arrays on that truss. The used batteries were installed on the cargo carrier for return to Earth on Atlantis. They also fixed a snagged cable on the Orbiter Boom Sensor System. The final task was to re-torque the bolts on the SGANT and then remove the launch locks and tether that were helping hold it in place. | ||||

| Good and Reisman first connected a liquid ammonia jumper hose. They then installed the final two new batteries on the truss and put the old batteries on the carrier. Next, they retrieved a grapple fixture from Atlantis' payload bay and brought it inside the station to be modified for future installation on the Zarya module. The pair also stowed some tools in an external toolbox outside the airlock for future spacewalks. | ||||
