Installed an experimental communication antenna on Zvezda 's nadir side, removed and stowed a failed plasma pulse generator experiment apparatus and a material exposure experiment from Zvezda, and installed a docking TV camera on the Rassvet module. | |||||

Installed two experiments for Earth seismic and lightning observations on the Zvezda module, removed two material exposure experiment panels from the exterior of the Zarya module, and jettisoned a foot restraint overboard. | |||||

Drew and Bowen installed a power extension cable between the Unity and Tranquility nodes to provide a contingency power source should it be required. The spacewalkers then moved the failed ammonia pump module that was replaced in August from an its temporary location to the External Stowage Platform 2 adjacent to the Quest airlock. Drew and Bowen then installed a wedge under a camera on the S3 truss to provide clearance from the newly installed ELC-4. They next replaced a guide for the rail cart system used for moving the station robotic arm along the truss. The guides had been removed when astronauts were performing work on the station's starboard Solar Alpha Rotary Joint (SARJ), which rotates the solar arrays to track the sun. The final task was to “fill” a special bottle with the vacuum of space for a Japanese education payload. The bottle will be part of a public museum exhibit. | |||||

Drew removed thermal insulation from a platform, while Bowen swapped out an attachment bracket on the Columbus module. Bowen then installed a camera assembly on the Dextre robot and removed insulation from Dextre's electronics platform. Drew installed a light on a cargo cart and repaired some dislodged thermal insulation from a valve on the truss. | |||||

Feustel and Chamitoff retrieved the two MISSE 7 experiments and installed a new package of MISSE 8 experiments on ELC-2, which was already on the station. They installed jumpers between segments on the left-side truss, or backbone of the station, for ammonia refills; vented nitrogen from an ammonia servicer; they began to install an external wireless communication antenna on the Destiny laboratory that will provide wireless communication to the Express Logistics Carriers mounted on the station’s truss, but was cut short due to a bad CO2 sensor in Chamitoff's suit. | |||||

Feustel and Fincke refilled the Port 6 (P5) radiators with ammonia. They completed venting the early ammonia system, lubricated the port solar alpha rotary joint and parts of Dextre, a two-armed space station robot capable of handling delicate assembly tasks currently performed by spacewalkers. Fincke also installed grapple bars on the port radiators. | |||||

Feustel and Fincke installed a grapple fixture (a handle for the station's Canadarm2 to grab on to) on the Zarya module, to support robotic operations based from the Russian segment. They also installed additional cables to provide backup power to the Russian portion of the space station. The pair finished installing the wireless video system that was left unfinished during EVA 1. | |||||

Fincke and Chamitoff stowed the shuttle's 50-foot Orbiter Boom Sensor System (OBSS) on the right-side truss on a permanent stowage fixture. The pair then retrieved a grapple from the station's left-side truss and used it as a replacement for the grapple currently on the boom. They then released restraints from one of the arms spare arms for Dextre and replaced thermal insulation on one of the spare gas tanks for the Quest airlock. The arrival of the PMM module marked the completion of the US Orbital Segment. | |||||

This spacewalk was kind of special in that it was the last spacewalk performed while a space shuttle was docked to the station. However, other than the previous spacewalks during docked operations, this one was performed by the station crew and not by the space shuttle crew.
The need for this spacewalk arose since a failed pump module on the station should be returned for inspection to the ground on the space shuttle. This having been the main objective done during this EVA the spacewalkers also installed a Robotic Refueling Mission experiment and fully deployed the MISSE 8 experiment (which was only half deployed during a previous spacewalk). |

The spacewalkers installed laser communications equipment which eventually will test transmissions of up to 100 MB/s of Russian science data with the ground on the Zvezda service module.
Radioskaf-V a small satellite for a student experiment was deployed and an antenna which was used for the docking of Poisk was removed and brought back into the station. As part of the research work on the station the BIORISK experiment was installed on a handrail outside Pirs. Last but not least photographs were taken including some of an antenna with signs of degraded performance to support engineers on the ground to trouble-shoot the cause of the degradation. Due to time constrains the task to relocate the STEAL-1 cargo boom was canceled for this EVA. |
