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.

Main objective was to prepare the Pressurized Mating Adapter-3 (PMA-3) for installation of the second International Docking Adapter (IDA), which will accommodate commercial crew vehicle dockings. The PMA-3 provides the pressurized interface between the station modules and the docking adapter. Expedition 50 Commander Shane Kimbrough and Thomas Pesquet disconnected cables and electrical connections on PMA-3 to prepare for its robotic move on, March 26, 2017. PMA-3 will be moved from the port side of the Tranquility module to the space-facing side of the Harmony module, where it will become home for the docking adapter, which will be delivered on a future flight of a SpaceX Dragon cargo ship. The spacewalkers also installed on the starboard zero truss (ITS) a new computer relay box equipped with advanced software for the adapter.
The two spacewalkers lubricated the latching end effector on the Canadarm2 robotic arm, inspected a radiator valve suspected of a small ammonia leak and replaced cameras on the Japanese segment of the outpost. Radiators are used to shed excess heat that builds up through normal space station operation.

This spacewalk featured the astronauts reconnecting cables and electrical connections on PMA-3 at its new home on top Harmony. They also installed the second of the two upgraded computer relay boxes on the station's truss and installed shields and covers on PMA-3 and the now-vacant common berthing mechanism port on Tranquility.
