Examination of the starboard Solar Alpha Rotary Joint (SARJ) and return a trundle assembly to the station's interior.

Replacing a motor with electrical failures, the Bearing Motor Roll Ring Module (BMRRM), called the 'broom". The motor drives the starboard solar wings as they tilt along their axis to follow the sun for optimal power generation as the station orbits the Earth. The second main goal of the spacewalk was inspection of the starboard Solar Alpha Rotary Joint (SARJ). That device causes the starboard solar wings to rotate in a paddlewheel-like motion to keep the arrays pointed toward the sun.

Preparing the Columbus module for installation on Harmony. Originallly it was planned that Walheim and Schlegel had to do this EVA, but Schlegel became ill (propably he suffered on the space adaption syndrome), so Love had to do the first EVA. They installed the Power Data Grapple Fixture on Columbus, which allowed the space station’s robotic arm to grab the module and move it from the shuttle’s payload bay to Harmony at the end of this spacewalk. Preparing work to remove the Nitrogen Tank Assembly, a part of the station’s thermal control system, from the P1 truss. The tasks took more time than planned. At time they were one full hour behind the timeline.

Evaluating the Shuttle Tile Ablator-54, or STA-54, material and a tile repair ablator dispenser for use as a shuttle thermal protection system repair technique. The Tile Repair Ablator Dispenser, or T-RAD, is similar to a caulk gun. They used TRAD to mix and squirt out the STA-54 material into holes in several demonstration tiles. The repaired samples will be returned to Earth for extensive testing.

Moving the Orbiter Boom Sensor System, the 50 ft. extension of the shuttle's robotic arm, to a temporary location on the station's main truss or backbone. The OBSS was left on the station because shuttle Discovery doesn't have enough room in its cargo bay to carry both the boom and the large Japanese pressurized module on the STS-124 mission. The spacewalkers also installed a new trundle bearing assembly in the starboard Solar Alpha Rotary Joint to allow the joint to rotate a little bit more if necessary. That SARJ has had limited ability for several months, and metallic debris has been found inside it. Additional spacewalk tasks included inspecting the SARJ and collecting debris samples.

Transfer of the Orbiter Boom Sensor System back to the shuttle from its temporary location of the station's truss, or backbone. The crew then prepared the JEM PM for its removal from the shuttle's payload bay. Later that day, the JEM PM was be installed on the port side of Harmony.

After Canadarm2 released S6 and moved away, the spacewalkers plugged in power and data cables to connect the new hardware and remove launch restraints from the photovoltaic radiator and the boxes containing the new solar arrays. They also deployed the Beta Gimbal Assemblies, which contain the masts that support the solar arrays, and position the boxes for later deployment.

First task during this spacewalk was to prepare a worksite for new batteries that will be brought up on the STS-127 mission. They also installed a Global Positioning System antenna on the pressurized logistics module attached to the Kibo laboratory.

Moving one of the station's two Crew and Equipment and Translation Aid - or CETA - carts. The carts were moved to the port side of the station's truss during the previous mission to give the robotic arm's mobile transporter the best possible access to the starboard truss for the installation of the new truss segment and solar arrays. With that work done, one of the carts was moved back to the station's port side, leaving a cart for use on either side of the truss.

Replacing a wide field camera. They also swapped out three batteries and installed a mechanism for a spacecraft to capture for de-orbit at the end of the telescope's life.

Changing out three boxes, each containing two of the telescope's six gyroscopes, and three batteries.

Prepare connecting mechanisms for Kibo and the exposed facility, which the station's robotic arm will install later in the day. They also released bolts on an ammonia tank assembly as get-ahead work for the next shuttle mission, STS-128. Then, both worked to deploy the unpressurized cargo carrier attachment system (UCCAS) on the Port 3 truss that was jammed and couldn't be done on STS-119. The UCCAS will be used in the future to store equipment and supplies on the outside of the station.

Transport of spare parts from a cargo carrier to a stowage platform on the station's truss. These parts include: an antenna, a pump module and a rail mechanism that allows a transporter to move up and down the truss. They also relocated a grapple bar onto an ammonia tank assembly as a get-ahead for the STS-129 mission, targeted for November 2009. A planned installation of a camera on the Japanese Experiment Facility was postponed to a future EVA for want of time.

Preparing the exposed facility for experiment transfers and replace two out of the six batteries (four were planned) on the port side truss where they are housed to provide power for the truss.

Replacing the final four batteries on the port truss.

Removing covers from the Dextre robotic arm, reconfigure cables on a panel for some circuit breakers and deploy two additional payload attachment systems. They also installed a second camera that will provide video of experiments on the aft end of the exposed facility, a work, which was originally scheduled for EVA 4. Finally, they replaced an aging camera system on the starboard truss. Instead some get ahead tasks were completed which included installation of handrails and a portable foot restraint.

They worked the heater cables on a docking adapter in advance of the Tranquility node's installation on Unity's port side and deployed another cargo platform on the truss.

Preparing the Mini-Research Module 2, known as Poisk, for future Russian vehicle dockings.

Removing a cover that has been in place to protect a port on the Unity node, the location where Tranquility was attached robotically halfway through the spacewalk. Next, the spacewalkers removed and stored a spare parts platform from the Special Purpose Dexterous Manipulator, or Dextre, a two-armed space station robot capable of handling delicate assembly tasks currently performed by spacewalkers. Finally, they installed four electronics systems cables between Unity and Tranquility to bring the new node to life.

Installing ammonia plumbing connectors between Unity and Tranquility and covered them with thermal insulation. When turned on, the ammonia will provide cooling to Tranquility. Then they prepared a port on the Earth-facing side of Tranquility for the flight day 8 relocation and attachment of the Cupola.

Turning on the ammonia cooling lines between Unity and Tranquility, installing heater and data cables on Tranquility, removing insulation and launching locks from the newly-installed Cupola, and installed handrails on the outside of Tranquility.

The crew inside used the station's robotic arm to remove a new ammonia tank from shuttle's payload bay and temporarily stow it on the station. Ammonia is used to move excess heat from inside the station to the radiators located outside. The spacewalkers then retrieved a seed experiment outside the Japanese laboratory. Next, the pair installed a grapple bar to the new ammonia tank on the station's truss. The pair also replaced a failed gyroscope that is part of the station's navigation system. They also accomplished several "get-ahead" tasks, removing 11 out of 12 p-clamps slated for a future spacewalk.

Using the station's arm, the astronauts removed the empty ammonia tank from the station's truss and temporarily stowed it on an equipment cart. The new tank then was installed and connected to the truss for use. Connecting the nitrogen and ammonia fluid lines was delayed for this spacewalk because of the delays getting the tank installed. The station's arm then temporarily stowed the old tank on another part of the station's structure until the mission's third spacewalk.

First they finished the complicated change out of the large ammonia tank assembly. Using the station's arm, the crew moved the old tank into the shuttle's payload bay for return to Earth. The spacewalkers also removed the grapple bar from the old ammonia tank and stowed it on a spare parts platform. Finally Anderson and Mastracchio retrieved debris shields from the Quest airlock to return to Earth.

Installing a spare space-to-ground Ku-band antenna on the station's truss, or backbone. Then they installed a new tool platform on Dextre. The spacewalkers breaked the torque on bolts holding batteries in place on the truss, in preparation for their removal and replacement on the second and third spacewalks. Battery preparation work was deferred from STS-131 to this flight.

Removing and replacing 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. In addition to the original tasks Bowen and Good relieved a snagged cable that is preventing full use of the laser imager and video camera. The equipment is located on the Orbiter Boom Sensor System.

Installing 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 for use as a spare.

Preparing the recently delivered Russian Rassvet Module for future automated dockings by Russian spacecraft

They removed hose clamps and then started disconnecting umbilicals from the broken space station coolant pump. However, difficulty unplugging one of the ammonia lines consumed a couple of hours and a leak seen from that connector once it finally cooperated prevented the astronauts from progressing any further in their work.

Removing the old pump and stowing it on a payload attachment bracket on the Mobile Base System on the station's truss while preparing the replacement pump for its removal from a stowage platform adjacent to the Quest airlock and its installation on the truss during a third spacewalk.

Installation of a spare ammonia pump module on the S1 Truss.

Installing a multipurpose workstation on the starboard side of the Zvezda service module’s large-diameter section, cleaning thermal insulation around the vents for the Elektron oxygen-generation system and relocating a television camera from one end of the Rassvet docking compartment to the other (failed due to interference with insulation where it was to be installed).

Completing installation of a new high-speed data transmission system, removing an old plasma pulse experiment, installing a camera for the new Rassvet docking module and retrieving a materials exposure package.

Installing two experiments. One will collect information useful in seismic forecasts and earthquake predictions, and the second will look at gamma splashes and optical radiation during terrestrial lightning and thunderstorms. The spacewalkers also retrieved a pair of panels exposed to space as part of an experiment to identify the best materials for building long-duration spacecraft. The cosmonauts also deployed an experiment called ARISSat-1, or Radioskaf-V, a boxy 57-pound nanosatellite that houses congratulatory messages commemorating the 50th anniversary of Yuri Gagarin's launch to become the first human in space.

They installed a power extension cable between the Unity and Tranquility nodes to provide a contingency power source should it be required. The spacewalkers moved the failed ammonia pump module that was replaced in August 2010 from an attachment bracket to a stowage platform adjacent to the Quest airlock. Drew and Bowen installed a piece of hardware that will go under a camera on the truss. The hardware will tilt the camera to provide clearance for a spare part to be installed on a future mission. They next replaced a guide for the rail cart system used for moving cargo along the truss. The guides were removed when the astronauts were performing work on the station's starboard Solar Alpha Rotary Joint, which rotates the solar arrays to track the sun.

The astronauts removed thermal insulation from a platform, while Bowen swaped out an attachment bracket on the Columbus module. Bowen then installed a camera assembly on the Dextre robot then removed insulation from Dextre's electronics platform. Drew installed a light on a cargo cart and repair some dislodged thermal insulation from a valve on the truss then remove other insulation from Tranquility. The final task was be to "fill" a special bottle with space for a Japanese education payload. The bottle will be part of a museum exhibit for public viewing.

They retrieved two experiments and install a new package of experiments on ELC-2, which is already on the station. Next they installed jumpers between segments on the left-side truss, or backbone of the station, for ammonia refills; vent nitrogen from an ammonia servicer; and installed 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.

The astronauts refilled radiators with ammonia. They also completed venting the early ammonia system, lubricated a left-side solar joint and parts of Dextre, a two-armed space station robot capable of handling delicate assembly tasks currently performed by spacewalkers.

Installing a grapple, or handle for the robotic arm on the station to grab, 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.

Fincke and Chamitoff stowed the shuttle's 50-foot boom on the right-side truss on a permanent stowage fixture, retrieved the 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 on Dextre and replaced thermal insulation on one of the spare gas tanks for the Quest airlock.

Transfer of a failed ammonia pump to the shuttle cargo bay, transfer of the Robotic Refueling Mission (RRM) to the station and place an experiment on ELC-2 for long-duration exposure.

Moving a small crane, installing a communications terminal and removing and inspect antennas. Other tasks included installing a materials science experiment and deploying a micro-satellite.

The tasks included: space crane Strela 1 relocation from DC1 to MRM2, using Strela 2, jettison MLI (Multi-Layer Insulation) cover, installing the Strela 1 on MRM2 (to aid future EVAs), stowing Strela 2 at DC1, installing the Vinoslivost Materials Sample Experiment on the DC1, taking a sample from the MLI insulation of the SM to look for any signs of living organisms and collecting one (of two planned) samples from the "Test" experiment.

The cosmonauts moved a Strela-2 cargo boom from the Pirs docking compartment to the Zarya module. This allows Pirs to be undocked at a later date making room for the new Russian multipurpose laboratory. Other tasks included releasing a small satellite and installing debris shields.

The astronauts replaced a faulty power routing unit (partly failed) on the station's truss and run cables for an upcoming Russian laboratory module.

The astronauts completed the installation of a spare power unit on the station's truss.

The astronauts repaired an ammonia leak on one of the station's port-side radiators.

They installed and connected the Obstanovka plasma wave experiment, a Russian investigation into space weather in Earth’s upper atmosphere. This task includes the planned jettison of two probe containers and a cable reel. They then removed a container from the Russian experiment Biorisk, which looks at the effects of microbial bacteria and fungus on structural materials used in spacecraft construction.

Inspection and replacement of a pump controller box on the station’s far port truss (P6) suspected of leaking ammonia coolant.

They replaced a fluid flow regulator on the Russian segment’s Zarya module. They also removed the Photon-Gamma unit of the Molina-Gamma experiment, which measures gamma splashes and optical radiation during terrestrial lightning and thunder conditions, from a portable workstation on Zvezda.

The astronauts replaced a space-to-ground communications receiver and wireless video equipment and installed power and cables for a Russian multipurpose laboratory module that will be launched later in 2013. The new module will serve as a research facility, docking port and airlock for future Russian spacewalks and will replace the Pirs module.

The spacewalk was terminated after just one hour due to an unexplained build up of water inside the space suit helmet of European Space Agency astronaut Luca Parmitano.

They continued routing power and Ethernet cables for the future arrival of the Russian Multipurpose Laboratory Module, which will be launched aboard a Proton rocket from the Baikonur Cosmodrome in Kazakhstan. They also installed on the Poisk module a panel of experiments designed to collect data on the effects of the microgravity environment in low-Earth orbit.

The cosmonauts removed a space laser communications system from the hull of the Zvezda service module and planned to install a pointing platform on which a small optical telescope will be installed on a future Russian spacewalk. This task failed.

The cosmonauts carried the Olympic torch when they venture outside the International Space Station. After the photo opportunity, they prepared a pointing platform on the hull of the station's Zvezda service module for the installation of a high resolution camera system in December 2013, relocate of a foot restraint for use on future spacewalks and deactivate an experiment package.

The EVA mainly focused on disconnecting the failed loop A pump module from its location on the Starboard 1 (S1) Truss - including the infamously difficult ammonia disconnections.

They removed a spare pump module from the ESP-3 and installed it on the Starboard 1 (S1) Truss.

The cosmonauts attempted to install a pair of cameras on the Zvezda Service Module as part of a Canadian commercial endeavor designed to downlink Earth observation imagery and to refresh experiments.

Reinstalling a pair of high-fidelity cameras as part of a commercial endeavor between a Canadian firm and the Russian Federal Space Agency. Oleg Kotov and Sergei Ryazansky previously attempted to install the cameras during a marathon 8-hour, 7-minute spacewalk on December 27, 2013 - the longest Russian spacewalk ever conducted - but had to return them to the airlock when Russian flight controllers did not receive the expected telemetry.

The astronauts replaced a backup multiplexer-demultiplexer (MDM) that failed during routine testing April 11, 2014. The box is one of the station's two external MDMs that provide commands to some of the space station's systems, including the external cooling system, solar alpha rotary joints (SARJ) and mobile transporter rail car.

The primary objectives of the spacewalk were focused at servicing the exterior of the Zvezda service module and the experiments mounted in that location. The two spacewalking cosmonauts installed an automated phased antenna array (AFAR), which will serve as part of the Russian command and telemetry system. They also relocated a part of the Obstanovka experiment - which is used to monitor the presence of charged particles and plasma in the environment of Low Earth Orbit (LEO). Other tasks included verifying the correct installation of the universal work platform (URM-D), taking samples from one of Zvezda's windows, and jettisoning an experiment frame.

The cosmonauts deployed a nanosatellite, installed two experiment packages (EXPOSE-R and Plume Impingement Deposit Monitoring) and retrieved others (CKK#1, Vinoslivosk and Biorisk). In addition they installed holder on Automatic Phased Array (AFAR) antenna, took surface samples from a window on Zvezda and photographed Multi-Layer Insulation from the exterior of the Russian ISS segment.

The astronauts moved a failed cooling pump from temporary to long-term storage on the station's truss. They also installed a new relay system that will provide backup power options to the mobile transporter, which moves the large robotic arm around the out outside of the space station.

The two-man team replaced a sequential shunt unit electronics box, a voltage regulator, on the starboard truss that failed in mid-May. Although the station has since operated normally on seven of its eight power channels, the voltage regulator replacement is considered a high priority.

The cosmonauts removed and jettisoned several pieces of hardware no longer needed on the Russian segment of the station and conducted a detailed photographic survey of the exterior surface of the Russian modules.

The astronauts started routing cables for the International Docking Adapter (IDA). In preparation for the arrival of new commercial crew vehicles to the ISS in late 2017 - which will use a brand new docking system - the existing docking ports on the ISS need to be converted to the new standard, before any commercial crew vehicles can dock to the outpost.

The astronauts unfurled and hooked up two more long cables and Terry Virts lubricated the grapple fixture on the end of the space station's robot arm (SSRMS).

They installed new antennas and cabling needed for communications between the station and commercial crew capsules bound for, or departing from, the new docking adapters.

They left the Pirs docking compartment in their Russian Orlan spacesuits for a photographic inspection of the station's Russian segment, retrieval of an experiment, window cleaning and surface sampling.

The EVA focused on station upgrades and maintenance tasks, including installing a thermal cover on the Alpha Magnetic Spectrometer, which is a state-of-the-art particle physics detector that has been attached to the station since 2011.

The astronauts attempted to restore the port truss ammonia cooling system to its original configuration. A spacewalk conducted in November 2012 tried to isolate a leak in the truss' cooling supply, but the leak was subsequently traced to a different component.

The pair moved the station's mobile transporter rail car so it can be latched in place ahead of the docking of a Russian cargo resupply spacecraft on December 23, 2015.

The astronauts replaced a failed voltage regulator that compromised one of the station's eight power channels on November 13, 2015. The unit was relatively easy to replace because it is a simple box that can be removed by undoing one bolt. Additional tasks included deploying cables for the future installation of an International Docking Adapter (IDA) that will accommodate U.S. commercial crew vehicles, and retrieving a broken light from a truss camera.

The spacewalkers performed works with the experiment Test at two locations: they took away samples from the outer surface of the docking compartment Pirs hatch and in the area of the cover window #8 at the service module Zvezda. Goal of the experiments is to develop methods for detecting leaks and control of elements of the exterior surface of the ISS.
The cosmonauts also dismantled a monoblock responsible for exposing samples of organic and biological materials in open space (experiment Expose-R) and set the unit samples #2 from an experiment for the study of space influence on the mechanical properties of materials. At the same module, they had to replace a removable cassette container, where the samples are placed of the exterior of stations in conditions of prolonged exposure, change the orientation of the pressure control unit on the module Poisk.
One of the important tasks were works on an experiment with the goal to develop technologies for sticking film thermal control coating, secure package screen-vacuum thermal insulation on the surface to be repaired and transactions that require bonding film materials in space flight.
For more convenient travel on the outer surface of the ISS the spacewalkers installed handrails on the soft part of the conical device of the Functional Cargo Block Zarya. Upon completion of the main tasks the cosmonauts started a photo documentation of the external surface of the ISS Russian segment.

The two astronauts ventured outside the space station's Quest airlock to install the first of two international docking adapters (IDAs) onto Pressurized Mating Adapter-2 (PMA-2), located on the forward end of the Harmony module.

Working on the port side of the orbiting complex's backbone, or truss (ITS), the astronauts retracted a thermal radiator that is part of the station's cooling system. The radiator is a backup that had been deployed previously as part of an effort to fix an ammonia coolant leak. They also tightened struts on a solar array joint, and installed the first of several enhanced high-definition television cameras that will be used to monitor activities outside the station, including the comings and goings of visiting cargo and crew vehicles.

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.

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