Relocating two equipment carts, setting the stage for the installation of the starboard S6 truss (scheduled for February 2009). The spacewalkers also lubricated the end effector, or hand, of the Canadarm2, the station's robotic arm. They also continued lubricating the starboard SARJ and replacing trundle bearings.

Removing several thermal covers on the port SARJ. Kimbrough lubricated the port SARJ, while Bowen reinstalled the thermal insulation covers (removed on first EVA) on Kibo. He then installed two GPS antennas on Kibo's logistics module, while Kimbrough installed a new TV camera on the truss.

Working on the right side truss of the space station (ITS), the astronauts installed adapter plates and hooked up electrical connections for three of six new lithium-ion batteries that were delivered to the station in December 2016 by transport spacecraft HTV-6.
