Launch from the Baikonur Cosmodrome (Gennadi Padalka and Michael Barratt with Soyuz TMA-14). Koichi Wakata was onboard the ISS since March 17, 2008 (arrival with STS-119). He was replaced by Nicole Stott (arrival with STS-128).
Roman Romanenko, Frank De Winne and Robert Thirsk arrived with Soyuz TMA-15 on May 29, 2009. For the first time the resident crew of the ISS consists of six persons.
The only EVA in this expedition was performed by Gennadi Padalka and Michael Barratt on June 05, 2009 (4h 54m) to prepare Pirs for the arrival of a new Russian module called the Mini-Research Module 2, or MRM2.
An IVA by Gennadi Padalka and Michael Barratt occurred on June 10, 2009 (0h 12m). It was an interior spacewalk to the transfer compartment between the Zvezda service module and the Zarya module for setting the stage for the MRM2's launch and automated linkup.
STS-127 docked with the International Space Station on July 17, 2009.
The main goal of STS-127 (ISS-2J/A JEM EF, JEM ELM-ES) was to deliver and install the third and the last piece the Japanese Exposed Facility (JEM EF) to Kibo and the Kibo Japanese Experiment Logistics Module - Exposed Section (JEM ELM-ES). The exposed facility (a kind of "porch") is a part of Kibo that will allow astronauts to perform science experiments that are exposed to the vacuum of space. The exposed section is similar to the logistics module on the Kibo laboratory, but is not pressurized. Once its payloads are transferred to the JEM EF, the JEM ELM-ES will be returned to the payload bay.
Also inside the payload bay was an Integrated Cargo Carrier-Vertical Light Deployable (ICC-VLD), containing a variety of equipment and spare components for the station. The carrier contained six new batteries for installation on the P6 truss, that was installed during two of the mission's spacewalks, as well as a spare space-to-ground antenna and a spare linear drive unit and pump module which was stored on an external stowage platform on the station's truss during one of the spacewalks.
The shuttle also delivered a new Flight Engineer - Timothy Kopra - to join the Expedition 20 crew, and return Expedition 20 Flight Engineer Koichi Wakata of the Japan Aerospace Exploration Agency to Earth.
The final components of Kibo will flew to the space station on STS-127. The STS-127 (2J/A) mission concluded the Kibo assembly, paving the way for the full utilization stage of Kibo.
On this third and last Kibo-designated assembly mission, Kibo's final components, the Exposed Facility (JEM EF) and the Experiment Logistics Module - Exposed Section (JEM ELM-ES), was delivered to the International Space Station. Installation of these components concluded assembly of the Japanese complex facility on the station.
The EF is a multipurpose experiment platform on which various scientific experiments can be performed using the microgravity and vacuum environment of space.
The JEM ELM-ES is a logistics carrier which was launched and returned on the STS-127 mission. On this flight, the JEM ELM-ES carried three JEM EF payloads to the station.
The JEM EF became operational during the STS-127 mission. Kibo's scientific capability was doubled when the platform for space-exposed experiment activities was ready.
A few hours after Endeavour's docking on the third day of the flight, Timothy Kopra and Koichi Wakata exchanged custom-made Russian Soyuz spacecraft seat liners. With that exchange, Koichi Wakata became part of Endeavour's crew. Timothy Kopra, meanwhile, joined the Expedition 20 crew - the first space station crew with a full complement of six astronauts. The commander, Russian cosmonaut Gennadi Padalka, and NASA Flight Engineer Michael Barratt launched to the station in the Russian Soyuz TMA-14 in March 2009. The second half of the crew - European Space Agency astronaut Frank De Winne, Russian cosmonaut Roman Romanenko, and Canadian Space Agency astronaut Robert Thirsk - took Soyuz TMA-15 to the station in May 2009. Koichi Wakata arrived aboard space shuttle Discovery during the STS-119 mission in March 2009. In September 2009, Timothy Kopra returned to Earth on shuttle mission STS-128, and Nicole Stott took his place.
A set of experiments to be deployed on the ISS were carried by STS-127, namely Dosimetry for Biological Experiments in Space (ESA), Validation of Procedures for Monitoring Crew Member Immune Function, the student-made Image Reversal in Space (CSA/ISU), Nutritional Status Assessment (NASA), NASA Biological Specimen Repository and Tomatosphere-II (CSA).
The first EVA by David Wolf and Timothy Kopra occurred on July 18, 2009 (5h 32m) to prepare connecting mechanisms for Kibo and the exposed facility, which the station's robotic arm installed 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.
Although the actual installation of Kibo's exposed facility was done robotically, David Wolf and Timothy Kopra began the first spacewalk by making preparations for that installation at both ends. David Wolf made his way to the laboratory to remove some insulation currently covering its berthing mechanism that the exposed facility was attached to. To do so, he released four fasteners and jettisoned the insulation. While he was in the area, he also tucked two grounding tabs on the Japanese robotic arm out of the way of the arm's camera - they're currently interfering with the view.
At the same time, Timothy Kopra was working inside the shuttle's cargo bay on the exposed facility end of that preparation. He started by removing insulation from its berthing mechanism where it will attach to the Kibo laboratory, by releasing four fasteners and storing the insulation. He then disconnected the power cable that keeps the exposed facility running while it's in the cargo bay.
The shuttle's robotic arm had already latched onto the exposed facility before the spacewalk started, and after the power cable was disconnected, the spacewalkers had done their part in the preparations for its installation. Afterward, the station robotic arm maneuvered into place, and the shuttle robotic arm picked up the facility from the shuttle's cargo bay and handed it off to the station robotic arm. The station arm then flew it to the Kibo laboratory for installation.
Meanwhile, David Wolf and Timothy Kopra continued on with their spacewalk activities. Already in the shuttle's cargo bay, Timothy Kopra went ahead and disconnected the power cables providing electricity to the integrated cargo carrier to which the spare station equipment that Endeavour is carrying are attached. And he removed a contamination cover on one of the experiments the exposed facility's experiment carrier is carrying - MAXI, or Monitor of All-sky X-ray Image.
After that, Timothy Kopra moved to the top of the Harmony node to secure a cover on its common berthing mechanism. He moved farther aft on station to pick up some tools on the station's zenith truss segment, and then to the left side of the Unity node to open another cover on its common berthing mechanism.
David Wolf moved from the Kibo laboratory to the station's port, or left, truss. He paused at the innermost section of the truss to loosen four bolts on the grapple bar of an ammonia tank assembly to speed up another task during the second spacewalk, then continued on to the port crew equipment and translation aid, or CETA, cart. There he was moving and restraining a foot restraint and brake handles out of the way to prevent them from interfering with the rotating solar alpha rotary joint.
For the rest of the spacewalk, David Wolf and Timothy Kopra worked together to set up two systems for attaching cargo to the station's truss - an unpressurized cargo carrier attachment system, or UCCAS, and a payload attachment system, or PAS. Though they have different names, the two systems are almost identical. During the last shuttle mission to the space station, spacewalkers ran into problems when they tried to set up the UCCAS on the port 3, or P3, segment of the station's truss. A jammed detent pin kept it from unfolding as it was supposed to. So David Wolf and Timothy Kopra came back for another try during their spacewalk. They used a specially built detent release tool to help clear the jam and allow them to fully install the UCCAS.
After getting the UCCAS into place, David Wolf and Timothy Kopra moved to the starboard side of the truss to set up a PAS on the S3 truss segment. The spacewalkers first removed brackets and pins holding the latch in place, moved the latch into position and then reinstalled the brackets and pins.
On July 19, 2009 a malfunction in a new toilet in the Destiny laboratory caused the crew to use the one in the Russian segment while attempts were made to identify the fault. Meanwhile the shuttle was cleared for reentry.
The second EVA was performed by David Wolf and Thomas Marshburn on July 20, 2009 (6h 53m) to 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.
The second spacewalk focused primarily on transferring the spare equipment brought up by the shuttle to a storage location on the station's truss segment.
Between the first and second spacewalk, Mark Polansky and Douglas Hurley used the shuttle robotic arm to unpack the integrated cargo carrier that held all the spare equipment the shuttle was delivering to the space station. On flight day 6, before the second spacewalk started, Julie Payette and Koichi Wakata took over using the station robotic arm and maneuvered the carrier to be installed temporarily on the truss.
This had to be done before the spacewalk started, because David Wolf's first task was to climb into a foot restraint on the station's robotic arm so that he could transfer the equipment from the carrier to an external stowage platform.
Together, David Wolf and Thomas Marshburn detached first the spare space-to-ground antenna from the cargo carrier. David Wolf then carried it via the robotic arm to the stowage platform, where he and Thomas Marshburn installed it. They then repeated the process with the spare pump module and the spare linear drive unit.
They spent their remaining time outside adding vision equipment on the newly installed exposed facility, which helped with the installation of the exposed facility's experiment carrier the following day. For launch, it was locked into a temporary spot on the exposed facility, and David Wolf and Thomas Marshburn needed to release six bolts, removed some insulation and disconnected a power cable to retrieve it. To install it in its permanent location on the forward end of the exposed facility, they used two bolts to secure it and then reconnect its power cable.
The third EVA by David Wolf and Christopher Cassidy was conducted on July 22, 2009 (5h 59m) to prepare 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. This EVA was shortened by NASA managers when astronaut Christopher Cassidy's carbon dioxide levels showed an upward trend due to a problem with his spacesuit's CO2 removal system. The calling off the spacewalk was simply a precaution.
David Wolf relocated a worksite interface and a handrail from their current location on the Harmony node to a new site on the Columbus laboratory. Christopher Cassidy, meanwhile, prepared the experiments and equipment brought up inside the exposed facility's experiment carrier to be transferred to the exposed facility itself by removing insulation. The carrier will have been installed on flight day 7 by Mark Polansky and Julie Payette at the shuttle's robotic arm and Douglas Hurley and Koichi Wakata at the station's.
Christopher Cassidy started with the interorbit communication system, which had two covers for Christopher Cassidy to remove and jettison and one to bring back inside. He also needed to release the equipment's antenna holding mechanism, which required removing two bolts. Christopher Cassidy then moved on to the space environment data acquisition equipment - attached payload.
From there, both spacewalkers moved to the end of the port side of the station's truss for the battery work. Before the spacewalk started, Douglas Hurley and Julie Payette used the station's robotic arm to maneuver the integrated cargo carrier, to which the new batteries for the P6 solar array were attached, as close to David Wolf and Christopher Cassidy's worksite as possible - almost as far out as the arm can reach.
David Wolf and Christopher Cassidy replaced two of the six batteries during this spacewalk. The new batteries were designated by letters A through F, and the old batteries numbered one through six. Christopher Cassidy removed an old battery from the solar array's integrated electrical assembly by installing two "scoops" that was used by the spacewalkers to maneuver the batteries, and then removing two bolts. He then handed it off, got out of the foot restraint he was working in, moved closer to David Wolf and took hold of the battery. David Wolf released the battery, moved slightly further down the truss and positioned himself to take hold of the battery. Christopher Cassidy handed the battery to David Wolf and then moved himself closer to once again take hold and control the battery. The process was called "shepherding", and might appear as "inch-worming" the battery along except that one person is always holding a 367-pound battery.
To install the battery in a temporary storage location on the integrated electrical assembly, David Wolf used one of the scoops to attach it to a multi-use tether, or ball-stack, and end effectors. The spacewalkers then removed battery A from the integrated cargo carrier and shepherd it back to the integrated electrical assembly for installation in slot 1. The next step was to remove battery 4, shepherd it to the cargo carrier to be installed in slot A, and remove battery B to be installed in slot 4.
The process continued until two batteries were installed, then the first battery was removed from its temporary storage location and installed in the vacant spot on the cargo carrier.
The fourth EVA was performed by Thomas Marshburn and Christopher Cassidy on July 24, 2009 (7h 12m) to replace the final four batteries on the port truss.
Thomas Marshburn and Christopher Cassidy spent the first half of spacewalk four finishing up the battery swap work that David Wolf and Christopher Cassidy started. They used the same procedure. The spacewalkers will wrapped up their work by installing the exposed facility's aft vision equipment, in a process similar to that performed by Thomas Marshburn and David Wolf during the second spacewalk.
The fifth and final EVA by Thomas Marshburn and Christopher Cassidy occurred on July 27, 2009 (4h 54m) to remove 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.
The last spacewalk of the mission was devoted primarily to get-ahead tasks that were not able to be finished during the last shuttle mission to the space station. Thomas Marshburn's first job took him to the station's special purpose dexterous manipulator - also known as Dextre - on the exterior of the Destiny laboratory. He was resecuring two thermal covers on Dextre's orbital replacement unit tool changeout mechanisms - in other words, one of the robot's wrist joints.
While he did so, Christopher Cassidy swapped two connectors on a patch panel on the station's zenith truss segment.
The two then worked together to first set up two more payload attachment systems - on the inboard and outboard sides of the nadir portion of the S3 truss - following the procedure that David Wolf and Timothy Kopra used during the first spacewalk, and installed a wireless video system external transceiver assembly, or WETA, on the same segment. WETAs support the transmission of video from spacewalkers' helmet cameras. To do so, Thomas Marshburn removed a dummy box currently in the location, and then attached the WETA to a stanchion. Christopher Cassidy connected three cables to the assembly.
On July 28, 2009 STS-127 undocked from the ISS and moved to a distance of about 450 feet, where Douglas Hurley began to fly around the station. Once Endeavour completed 1.5 revolutions of the complex, Douglas Hurley fired Endeavour's jets to leave the area. The shuttle moved about 46 miles from the station and remained there while ground teams analyzed data from the late inspection of the shuttle's heat shield. The distance was close enough to allow the shuttle to return to the station in the unlikely event that the heat shield is damaged, preventing the shuttle's safe re-entry.
Progress M-67 was successfully launched at 10:56:56 UTC on July 24, 2009. It was originally scheduled to dock with the ISS on July 26, 2009, two days after launch, but following delays to the launch of Space Shuttle Endeavour on mission STS-127, it was decided before launch to extend the free flight period to allow the Shuttle to remain docked for the full duration of its mission. Although the Shuttle and Progress spacecraft do not use the same docking port on the ISS, a Progress cannot dock or undock whilst a Shuttle is docked to the station. Following Endeavour's departure on July 28, 2009, Progress M-67 docked to the aft docking port of the Zvezda module on July 29, 2009 at 11:12 UTC after five days of free flight. During rendezvous, the Progress approached the station in an incorrect orientation, before the automated Kurs system was deactivated, and cosmonaut Gennadi Padalka took over using the manual TORU system. The spacecraft delivered 50 kg of oxygen, 210 kg of water, about 830 kg of propellant and more than 1,200 kg of dry cargo to the ISS. Progress M-67 undocked from the ISS on September 21, 2009 at 07:25 UTC, in order to free up the aft docking port on Zvezda for the arrival of Soyuz TMA-16. Progress M-67 was successfully deorbited and burned up upon atmospheric reentry on September 27, 2009.
The next Space Shuttle docking to the International Space Station was STS-128. The docking occurred on August 31, 2009.
The primary payload of STS-128 (ISS-17A MPLM Leonardo, LMC) was the Multi-Purpose Logistics Module Leonardo to assist with establishing a six-man crew capacity by bringing extra supplies and equipment to the station. The Multi-Purpose Logistics Module contained three racks for life support, a crew quarter to be installed in Kibo, a new treadmill (COLBERT) that will temporarily be placed in Node 2 and later in Node 3, and an Air Revitalization System (ARS) that will temporarily be placed in Kibo and later in Node 3.
Three spacewalks were planned during the mission, which removed and replaced a materials processing experiment outside ESAs Columbus module, and to return an empty ammonia tank assembly.
The mission of Christer Fuglesang was named Alissé by the European Space Agency. The name was proposed by Jürgen Modlich from Baierbrunn, Germany. The name refers to the 15th-century explorers who used the trade winds to follow Christopher Columbus across the oceans to the New World.
Nicole Stott replaced NASA astronaut Timothy Kopra as a long-duration crew member on the space station and a member of the Expedition 20 and 21 crews. Nicole Stott spent three months on the complex while Timothy Kopra returned home aboard Discovery. Nicole Stott returned in November 2009 on the shuttle Atlantis as part of the STS-129 crew.
Nicole Stott was originally scheduled to return aboard Soyuz TMA-15, but a change in the flight plan was made due to the possible flight delays in future shuttle missions, which may extend Canadian astronaut Robert Thirsk's mission beyond the six-month duration preferred for station crew members.
Less than two hours after the docking, hatches were opened between the two spacecraft to begin almost nine days of work between the two crews. Discovery's arrival at the station two days after launch again placed 13 crew members on the complex. The shuttle crew joined Gennadi Padalka of Russia, and Flight Engineers Michael Barratt and Timothy Kopra of NASA, Roman Romanenko of Russia, Robert Thirsk of the Canadian Space Agency and Frank De Winne of the European Space Agency.
Nicole Stott and Timothy Kopra exchanged Soyuz seatliners. With this procedure Nicole Stott joined Expedition 20 and Timothy Kopra joined the STS-128 crew.
During flight day 4, the MPLM Leonardo was berthed to the Nadir or earth facing port on Harmony using the Space Station Remote Manipulator System (SSRMS). Once it was berthed, the crews activated it and opened the hatch for ingress. Some more items were transferred from the shuttle mid-deck including the MDS experiment.
Housed for the ride to the station in the Leonardo Multi-Purpose Logistics Module in Discovery's payload bay were the Materials Science Research Rack (MSRR-1), the Minus Eighty Degree Laboratory Freezer for ISS (MELFI) and the Fluids Integration Rack (FIR). MSRR-1 was used for basic materials research related to metals, alloys, polymers, semiconductors, ceramics, crystals and glasses in the microgravity environment. MELFI was used for long-term storage of experiment samples that are to be returned to Earth for detailed analysis. The FIR is a fluid physics research facility designed to host investigations in areas such as colloids, gels, bubbles, wetting and capillary action, and phase changes, including boiling and cooling.
Leonardo, which served as a large moving van for supplies and equipment back and forth from the station, also was carrying a new crew quarters to provide more sleeping space for the expanded station crew members and a new exercise device called the Combined Operational Load Bearing External Resistance Treadmill, or COLBERT, coined after late-night cable entertainment personality Stephen Colbert. COLBERT was transferred to a temporary location in the Harmony node, but will ultimately reside in the new Node 3 module - Tranquility - that will be launched to the station in 2010 as a final connecting point for other modules on the U.S. segment of the complex, including the Cupola, a multi-windowed module to provide a vista-like view of the universe. COLBERT will not be checked out and activated until later in 2009.
In addition to the new treadmill, also referred to as "T2," the crew transferred a new Air Revitalization System (ARS) rack to the station for use in Tranquility to maintain a pristine environment for the expanded six-person crew on the outpost. The system includes another carbon dioxide removal system bed similar to the Carbon Dioxide Removal Assembly (CDRA) that resides in the U.S. Destiny laboratory. The rack was temporarily stowed in the Japanese segment of the station until Tranquility is in place to accept it on a permanent basis.
The first EVA by John Olivas and Nicole Stott occurred on September 01, 2009 (6h 35m) to prepare for the replacement of an empty ammonia tank on the station's port truss, or backbone, by releasing its bolts. They also retrieved a materials processing experiment (MISSE) and a European science experiment (EuTEF) mounted outside the Columbus laboratory and stowed them in Discovery's cargo bay for their return to Earth.
The work to replace the ammonia tank assembly on the first port segment of the station's truss - P1 - began on the first spacewalk of the mission. John Olivas and Nicole Stott removed the depleted tank from the truss, so that it was picked up by the station's robotic arm for storage until after the second spacewalk.
To remove it from the station's truss, John Olivas and Nicole Stott disconnected two lines used to transfer its ammonia, two lines which provide nitrogen for pressurization, and two electrical connections and released four bolts. They then worked together to lift the tank away from the truss and maneuvered it into position for the robotic arm to latch onto.
While the arm was still holding the tank assembly, Nicole Stott installed a foot restraint on it as well, which she then climbed into for the removal of the European Technology Exposure Facility, or MISSE. While Nicole Stott got into place, John Olivas documented the experiment's condition by taking some photographs. John Olivas then detached the experiment by releasing one bolt, and Nicole Stott lifted it away from its place on the Columbus laboratory. From there, Kevin Ford and Robert Thirsk drove her via the robotic arm to the shuttle's cargo bay, where she worked with John Olivas to store it on a cargo carrier for transport back to Earth. One bolt was used to attach it to the carrier.
The spacewalkers' final task was the removal of the sixth Materials International Space Station Experiment - or MISSE. Nicole Stott climbed out of the robotic arm's foot restraint and met John Olivas back at Columbus. (Although MISSE is a NASA experiment, it is located on the exterior of the Columbus laboratory.) While he waited for Nicole Stott to arrive, John Olivas closed the passive experiment containers in which the two parts of the MISSE experiment were housed, and disconnected two cables. John Olivas then removed the first of the containers and passed it on to Nicole Stott for installation in a storage location. The second was removed and stowed by John Olivas.
While the spacewalk was going on crew members inside were transferring the Crew Quarters, C.O.L.B.E.R.T treadmill and the Node 3 Air Revitalization System rack (ARS). The treadmill and ARS were temporarily stowed, while the crew Quarters was installed in the Kibo Module where setup and activation was begun.
During flight day 6 the joint crews continued the activation of the new crew quarters. The last of the major transfer items, the Fluids Integrated Rack (FIR), Materials Science Research Rack and the Minus Eighty Laboratory Freezer ISS 2 (MELFI-2) were transferred from the Multi-Purpose Logistics Module (MPLM) Leonardo.
The second EVA was performed by John Olivas and Christer Fuglesang on September 03, 2009 (6h 39m) to remove the new ammonia tank from the shuttle's payload bay and replacing it with the used tank on the station. The new tank, weighing about 1,800 pounds, was the most mass ever moved around by spacewalking astronauts. After the new tank was installed, the old one was stowed in the shuttle for its return to Earth. On Earth the tank will be refueled and delivered again to the ISS during the mission of STS-131.
The entire second spacewalk of the mission focused on completing the ammonia tank assembly swap. John Olivas began by removing insulation on the new ammonia tank while Christer Fuglesang got into position in the robotic arm's foot restraint. He and John Olivas then worked together to release the four bolts securing the assembly to the cargo carrier inside the shuttle's cargo bay. Kevin Ford and Nicole Stott then drove the robotic arm - carrying Christer Fuglesang and both ammonia tanks - to the installation site on the P1 truss segment.
John Olivas met Christer Fuglesang there, and together they drove the four bolts that held it in place. John Olivas then connected two electrical cables and four fluid lines.
With the new tank assembly installed, John Olivas and Christer Fuglesang prepared for the storage of the old tank assembly, still latched to the robotic arm. John Olivas tethered the old tank assembly to himself and then gave Kevin Ford and Nicole Stott the OK to command the robotic arm to release it. Then Christer Fuglesang attached his tether to the assembly and John Olivas removed his tether, allowing Christer Fuglesang and the old tank to make their way back to the shuttle's cargo bay via robotic arm. Once there, John Olivas and Christer Fuglesang installed it on the cargo carrier with four bolts.
On flight day 8 more transfer was completed by both crews. The space station crew calibrated the Oxygen Generation System (OGS) H2 sensor. Timothy Kopra and Nicole Stott continued their hand over activities, helping Nicole Stott who was taking over from Timothy Kopra.
The third and final EVA by John Olivas and Christer Fuglesang was conducted on September 05, 2009 (7h 01m) to prepare for the arrival of the Tranquility node by attaching two 18m long cables between the starboard truss and the Unity node, the area where Tranquility will be installed. Tranquility is targeted to arrive to the station on STS-130 in February 2010. The spacewalkers also replaced a communications sensor device, installed two new GPS antennas and a new circuit breaker.
The first tasks of the final spacewalk of the mission were finish work left by the previous space shuttle mission. The STS-127 spacewalkers completed the deployment of the one cargo attachment system on the P1 truss segment, but had to leave the set up of similar systems on S3 for future missions. On STS-119 a jammed detent pin on the first of the systems prevented them from deploying the P1 system. A special tool was built to assist with the deployment. The STS-127 spacewalkers were successful in clearing the jam. John Olivas and Christer Fuglesang had the same tool on hand for use if needed.
If the detent pin did not jam, however, the cargo attachment system was set up by removing brackets and pins holding it in place, moving it into its correct position and then reinstalling the brackets and pins.
Once that was complete, John Olivas and Christer Fuglesang worked together to remove and replace a failed rate gyro assembly in the center of the station's truss. To remove the failed assembly, John Olivas disconnected two cables and removed two bolts. Christer Fuglesang removed the final two holding the assembly in place, and then John Olivas removed it and temporarily stored it nearby. To install the new one, John Olivas and Christer Fuglesang each had to drive four bolts, and John Olivas then connected its two cables before moving on to the next task.
At this point in the spacewalk, John Olivas and Christer Fuglesang split up. John Olivas set up heater cables that will be used to keep the PMA 3 berthing port between the Unity and the coming Tranquility node warm so it can be pressurized. This will allow the station crew to prepare the vestibule for Tranquility node's arrival. That involved disconnecting four cables and wire-tying them into place along a handrails on the Unity node. One of them was connected to an outlet on Unity, the rest had caps installed on them.
Meanwhile, Christer Fuglesang replaced a failed remote power control module on the center segment of the station's truss. To remove the failed module, he simply released one bolt. To install the new unit, he slided it into place on a guide rail and then secured it using one bolt. He followed that up by installing an insulation sleeve on a cable inside the truss.
With those tasks done, Christer Fuglesang and John Olivas came together again in the center of the truss to route avionics systems cables. They were using wire ties to secure two cable bundles to handrails along the truss system and the Unity node, and then a panel on the truss.
John Olivas wrapped up the spacewalk by removing a damaged slidewire from a stanchion on Unity, while Christer Fuglesang installed a lens cover on a camera and light assembly on the space station's robotic arm.
Flight day 10 saw the joint crews transfer samples from the space station to the shuttle freezer known as Glacier. The samples will be returned to earth for examination by scientists who will develop ways to prevent bone and muscle loss in space as well as cures for other illnesses on earth. The crews also completed some close outs of the Multi-Purpose Logistics Module Leonardo. The last portion of the crew day was spent off duty.
On flight day 11 the joint ISS/shuttle crews completed transfers and closed the hatches with the MPLM. Once the hatches were closed, the MPLM was deactivated, demated and berthed back in the payload bay of the space shuttle. During this process José Hernández and Nicole Stott took part in a PAO event. The end of the crews work days saw the two crews say goodbye in a farewell ceremony and close the hatches between the shuttle and ISS. Once the hatches were closed, the Pressurized Mating Adapter 2 was depressurized, in advance of undocking. The shuttle crew setup and checked out the rendezvous tools before going to bed.
On September 08, 2009 STS-128 undocked from the ISS and moved to a distance of about 450 feet, where Kevin Ford began to fly around the station. Kevin Ford circled the shuttle around the station at a distance of 600-700 feet.
Once the shuttle completed 1.5 revolutions of the complex, Kevin Ford fired Discovery's maneuvering thrusters to leave the area. The shuttle began to increase its distance from the station with each trip around the Earth, while ground teams analyzed data from the late inspection of the shuttle's heat shield. However, the distance was close enough to allow the shuttle to return to the station in the unlikely event that the heat shield is damaged, preventing the shuttle's safe re-entry.
The Japanese freighter HTV arrived on September 17, 2009. HTV-1 was successfully launched at 17:01:46 UTC on September 10, 2009, to the initial orbit of 299.9 km apogee / 199.8 km perigee / 51.69° inclination (planned 300.0 ±2 km / 200.0 ±10 km / 51.67 ±0.15°). The launch took place from the Yoshinobu Launch Complex at the Tanegashima Space Centre, and was the first to use the second pad of the complex. It arrived at the Approach Initiation Point, 5 kilometers behind the space station at 13:59 UTC, and began its final approach sequence at 15:31. It approached to within 10 meters (33 ft) of the station, from where it was grappled using the Canadarm2 robotic arm of the space station, operated by Nicole Stott. Initial capture occurred at 19:47 UTC, with the procedure being completed at 19:51. Robert Thirsk then used Canadarm2 to move it to a "ready-to-latch" position over the nadir CBM port of the Harmony module. It arrived at this position at 22:08 UTC, and by 22:12 four latches had engaged to hold it in place. Sixteen bolts were subsequently driven in to achieve a hard mate. It remained berthed at the station until October 30, 2009.
HTV-1 carried four and a half tonnes of payload, lower than the six tonne maximum payload of the HTV in order to allow the spacecraft to carry additional propellant and batteries for the in-orbit verification phase of the flight. In the Unpressurised Logistics Carrier, the HTV-1 carried SMILES (Superconducting Submillimeter-Wave Limb Emission Sounder) and HREP (HICO-RAIDS Experiment Payload), which both were installed in the JEM Exposed Facility on the ISS. The Pressurised Logistics Carrier carried 3.6 tonnes of supplies for the International Space Station. It consisted of food (33% of weight), laboratory experiment materials (20%), robot arm and other hardware for JEM (18%), crew supplies including garments, toiletries, personal mail and photographs, fluorescent lights, waste buckets (10%), and packing materials (19%).
HTV departed the ISS on October 31, 2009 after being released by the station's robotic arm. The spacecraft re-entered the Earth's atmosphere on November 02, 2009 and disintegrated on re-entry as planned. HTV-1 was loaded with 199 items of discarded equipment & waste of 727.7 kg, as well as 896 kg empty racks, totaling 1,624 kg.
Koichi Wakata performed an experiment where he did not change his underpants in order to test a specially designed underwear which he wore for 1 month without washing or changing and did not develop body odor.
