ISS: Expedition 18 (original) (raw)

Launch from the Baikonur Cosmodrome (MichaelFincke and YuriLonchakov withSoyuz TMA-13). SandraMagnus arrived on November 16, 2008 withSTS-126. She was replaced by KoichiWakata on March 17, 2009 (arrival withSTS-119).

The Expedition 18 officially began with undocking of Russian spacecraftSoyuz TMA-12 on October 24, 2008 at 00:16:18UTC and Expedition 17 ended.

STS-126 docked with the International Space Station on November 16, 2008.
STS-126 (ISS-ULF-2MPLM Leonardo) included the Leonardo Multi-Purpose Logistics Module (MPLM) on its fifth spaceflight. Leonardo held over 14,000 pounds (6,350 kg) of supplies and equipment. Among the items packed into theMPLM were two new crew quarters racks, a second galley (kitchen) for theDestiny laboratory, a second Waste and Hygiene Compartment (WHC) rack (lavatory), the advanced Resistive Exercise Device (aRED), two water reclamation racks, spare hardware, and new experiments. Also included in Leonardo was the General Laboratory Active CryogenicISS Experiment Refrigerator, or GLACIER, a double locker cryogenic freezer for transporting and preserving science experiments. The shuttle also carried irradiated turkey, candied yams, stuffing and dessert for a special Thanksgiving meal at the station, as well as an Official Flight Kit with mementos for those who supported the astronauts and helped them complete their mission successfully.
The crew conducted four spacewalks to service and lubricate the complex's two Solar Alpha Rotary Joints (SARJ) that allow the station's photovoltaic cells to revolve like paddlewheels and point at the sun. The starboardSARJ has had limited use since September 2007. The spacewalkers also installed a new nitrogen tank, a global positioning system, antenna, and a camera on the station's Integrated Truss Assembly.
The shuttle delivered a newFlight Engineer, SandraMagnus to join the Expedition 18 crew, and returnFlight Engineer GregoryChamitoff to Earth.
Also carried was a Lightweight MPESS Carrier (LMC) carrying a Flex Hose Rotary Coupler (FHRC) and returning a Nitrogen Assembly Tank from 'Quest' for refurbishment.

There are two Solar Alpha Rotary Joints (SARJs) on the International Space Station. They connect thePort 3 andPort 4 (left side) truss segments and theStarboard 3 andStarboard 4 (right side) segments.P3/P4 was flown up on the STS-115 mission on September 09, 2006, whileS3/S4 was flown up on the STS-117 mission June 08, 2007. TheSARJ is a 10.5-foot diameter (129.5 inch = 3.2 meters) rotary joint that tracks the sun in the alpha axis that turns four port and four starboard solar arrays wings. The eight solar array wings (onP4,P6,S4 andS6) are used to convert solar energy to electrical power. TheSARJ continuously rotates to keep the solar array wings onS4 andS6 andP4 andP6 oriented toward the sun as the station orbits the Earth. TheSARJ rotates 360 degrees every orbit or about 4 degrees per minute.
TheSARJ weighs approximately 2,506 pounds (1,137 kg) and is made of aluminum and corrosion resistant steel. The major components of theSARJ are the Utility Transfer Assembly (UTA), Trundle Bearing Assemblies (TBA) (12 per joint), race rings (2 per joint) and Drive/Lock Assembly (DLA) (2 per joint) and the Rotary Joint Motor Controller (RJMC) (2 per joint). TheSARJ can spin 360 degrees using bearing assemblies and a control system to turn. All of the power flows through the UTA in the center of theSARJ. A large 10.5-foot (129.5-inch = 39.5 meters diameter), 229-pound (104 kg) geared race ring is secured to the structure by the TBAs and driven by the DLA using the software control commanded from the DLA/RJMC pair. The DLA engages the teeth of the race ring to rotate theSARJ. The gold plating on the TBA rollers is transferred from the roller to the race ring to lubricate the ring to create a lubricating film. EachSARJ has two race rings, an inboard race ring that is attached to theP3 orS3 truss and an outboard race ring that is attached to theP4 orS4 truss segment. The 12 TBAs are attached to the inboardSARJ race ring via mounts that do not rotate. The TBAs are the structural connection in orbit between the inboard and outboard race rings. The DLA also are attached to the inboardSARJ structure and have "follower assemblies" that act in the same fashion as the TBAs, helping to locate the driving gear relative to the race ring teeth. The UTA is an electrical roll ring assembly that allows transmission of data and power across the rotating interface so it never has to unwind. The UTA passes through the center, or hub, of the joint so it interfaces with both the inboard and outboard segments. The roll ring assemblies allow the outboard elements to rotate relative to the inboard elements while providing continuous data and power transmission.

A few hours after Endeavour's docking on the third day of the flight, SandraMagnus and GregoryChamitoff exchanged custom-made RussianSoyuz spacecraft seat liners. With that exchange, Sandra Magnus became a part of the Expedition 18 space station crew, and GregoryChamitoff became part ofEndeavour's crew.
SandraMagnus joined Expedition Commander MichaelFincke andFlight Engineer Cosmonaut YuriLonchakov who were launched to the complex in theSoyuz TMA-13 spacecraft on October 12, 2008 from the Baikonur Cosmodrome in Kazakhstan. In the spring 2009, SandraMagnus returned to Earth on shuttle missionSTS-119, while Michael Fincke and YuriLonchakov returned in theSoyuz in April 2009.

The firstEVA by HeidemarieStefanyshyn-Piper and StephenBowen occurred on November 18, 2008 (6h 52m) to replace a depleted nitrogen tank and a device used to help the flow of coolant from the truss, the backbone of the station. They also removed thermal covers from the JapaneseKibo module to inspect the berthing mechanism where the module's exposed facility will be installed during theSTS-127 mission in 2009. They also started inspecting, cleaning and lubricating the starboardSARJ and begin replacing 11 of 12 trundle bearings. One was replaced during theSTS-124 mission in June 2008.
The first order of business was to swap the external equipment just delivered by the space shuttle with equipment that was brought back to Earth. HeidemarieStefanyshyn-Piper removed an empty nitrogen tank assembly that has been waiting on the external stowage platform 3 on the port, or left, side of the station's truss since the June 2008STS-124 mission. After installing a foot restraint on the end of the station's robotic arm to stand in, HeidemarieStefanyshyn-Piper removed the tank and carried it as she rode the arm to the shuttle's cargo bay.
StephenBowen helped HeidemarieStefanyshyn-Piper remove the nitrogen tank, then took care of some minor tasks, including retrieving a camera and closing a window flap onHarmony's zenith common berthing mechanism. StephenBowen met HeidemarieStefanyshyn-Piper in the cargo bay to help stow the tank and remove a spare flex hose rotary coupler, or FHRC. FHRCs are used to transfer liquid ammonia across the rotary joints that allow the station's radiators to rotate.
HeidemarieStefanyshyn-Piper carried the FHRC back to the stowage platform via robotic arm, where she and StephenBowen installed it for future use. Then, while HeidemarieStefanyshyn-Piper climbed off of the robotic arm, Stephen Bowen removed some insulation from the common berthing mechanism that was used to attach the Japanese external facility to theKibo laboratory.
When those tasks were done, the spacewalkers started the mission's first round of starboardSARJ maintenance. The rotary joint has 22 protective insulation covers, of which no more than six can be removed at any one time. HeidemarieStefanyshyn-Piper began by opening cover eight. Cover seven was removed and left off during an inspection on a previous spacewalk. With the insulation covers removed, HeidemarieStefanyshyn-Piper had access to the 10th of the joint's trundle bearing assemblies, or TBAs, which connect the two halves of the joint and allow one side to rotate while the other stays still. Meanwhile, Stephen Bowen worked under covers 22 and one, on TBA six.
With the covers removed, HeidemarieStefanyshyn-Piper and StephenBowen then removed their respective TBAs and stowed them in special bags designed to hold one TBA apiece. With that equipment out of the way, the spacewalkers were able to begin cleaning the area under the open covers. First, they used a wet wipe to remove debris from the cleaner areas of the joint, then to clean off the damaged outboard outer canted surface.
Next, they used a grease gun to add a line of grease to the outer canted surface and used a scraper similar to a putty knife to remove some of the debris that has become "pancaked" on the surface. They cleaned the scrapers off inside of a debris container to prevent metal flakes from floating away, and then used a dry wipe to remove the grease from the area. Then they gave the entire area a final wipe with a dry wipe to remove any residual grease and debris.
Once the area is clean, the astronauts could begin lubricating the surface of the outboard ring. They use a grease gun with a special, j-shaped nozzle to add grease to the inner canted surface, and a straight-nozzle grease gun for the outer canted and datum A surfaces.
Finally, before closing the covers, HeidemarieStefanyshyn-Piper and StephenBowen installed clean trundle bearing assemblies in place of the ones they removed. HeidemarieStefanyshyn-Piper then repeated the process on TBA 11, under covers nine and 10. However, she did not reinstall TBA 11 until the second spacewalk.
About halfway into the spacewalk, one of the grease guns that HeidemarieStefanyshyn-Piper was preparing to use on theSARJ released some braycote grease into her crew lock bag, which is the tool bag the spacewalkers use during their activities. As she was cleaning the inside of the bag, it drifted away from her and toward the aft and starboard portion of the International Space Station. Inside the bag were two grease guns, scrapers, several wipes and tethers and some tool caddies. Stephen Bowen then shared bag and equipment with her.

On flight day 6 there were noEVA activities and the crew installed two crew quarters racks into theHarmony node, and installed a rack with equipment to be returned to Earth into theMPLM (Leonardo). The crew also began working on activating the Water Recovery System, so that samples of water from two areas could be taken and returned to Earth withEndeavour.

The secondEVA was performed by HeidemarieStefanyshyn-Piper and RobertKimbrough on November 20, 2008 (6h 45m) to relocate two equipment carts, setting the stage for the installation of the starboardS6 truss (scheduled for February 2009). The spacewalkers also lubricated the end effector, or hand, of theCanadarm2, the station's robotic arm. They also continued lubricating the starboardSARJ and replacing trundle bearings.
The first task of the second spacewalk gave RobertKimbrough a chance to ride the station's robotic arm. He and HeidemarieStefanyshyn-Piper moved the station's two Crew and Equipment and Translation Aid, orCETA, carts, the rail carts that allow astronauts to move equipment along the station's truss, from their current homes on the starboard side of the station's Mobile Transporter (MT) to the port side.
HeidemarieStefanyshyn-Piper got the carts ready for transfer by moving them into position and unlocking their wheel bogies. RobertKimbrough first carriedCETA 1 and thenCETA 2 as he was flown on the robotic arm from one side of theMT to the other. HeidemarieStefanyshyn-Piper met him there each time, to install the carts in their new locations.
When that task was done, RobertKimbrough climbed off of the robotic arm and removed the foot restraint HeidemarieStefanyshyn-Piper installed on the first spacewalk. This gave him access to the arm's latching end effector, or LEE, the snares that allow it to grasp equipment. Inside the station, DonaldPettit and SandraMagnus commanded the LEE, which has been experiencing some sticky spots, to open and close its snares. RobertKimbrough applied lubricant to the LEE's snare bearings and rotated the bearings using needlenose pliers to ensure the lubricant covers the bearings.
Meanwhile, HeidemarieStefanyshyn-Piper returned to the starboardSARJ to continue its cleaning and lubrication. Following the first spacewalk, theSARJ was rotated so that the areas HeidemarieStefanyshyn-Piper and StephenBowen already cleaned were under the joint's two drive lock assemblies, which cannot be removed easily. HeidemarieStefanyshyn-Piper reopened covers nine and 10 and cleaned the new area under them, before reinstalling TBA 11, which she removed during the first spacewalk, and reclosing the covers.
Next HeidemarieStefanyshyn-Piper removed and replaced TBAs eight and nine under cover five. When RobertKimbrough finished his work on the robotic arm, he joined her at theSARJ and work on TBAs 12, under covers 11 and 12.

On flight day 8 MichaelFincke and SandraMagnus tested latches on the Exposed Facility Berthing Mechanism for the JapaneseKibo laboratory. SandraMagnus continued with the installation of the Total Organic Carbon Analyzer (TOCA), while engineers on the ground worked through troubleshooting of the Urine Processor Assembly. The component ran initially on Thursday evening, but shut itself down during that initial test, and shut down again the following morning after two hours of operations.

The thirdEVA by HeidemarieStefanyshyn-Piper and StephenBowen was conducted on November 22, 2008 (6h 57m) to complete starboardSARJ cleaning, lubricating and trundle bearing work.
The third spacewalk of the mission was completely devoted to work on the starboardSARJ. Using the same methods, HeidemarieStefanyshyn-Piper opened covers 13 and 14, removed TBA one, cleaned and lubricated the area, installed a new TBA and closed the covers. She repeated the process on TBA two under covers 15 and 16 and TBA three under covers 17 and 18.
StephenBowen did the same for TBA four under covers 19 and 20, TBA six under covers 22 and one and TBA seven under covers two and three. He also removed TBA five under cover 20; however, it was replaced on a previous spacewalk, so he simply cleaned and re-installed it.

The two crews (Station and Shuttle) continued transfer operations on Flight day 10, and Michael Fincke and DonaldPettit worked together to reconfigure the Urine Processing Assembly (UPA) to try to dampen any vibration that may be contributing to the unit's shutting down prematurely. The unit had continued to operate sporadically, shutting itself down after two to three hours of operations, and the engineers on the ground were still evaluating the possible causes and solutions.

The fourth and finalEVA by StephenBowen and RobertKimbrough was performed on November 24, 2008 (6h 07m) to remove several thermal covers on the portSARJ. RobertKimbrough lubricated the portSARJ, while StephenBowen reinstalled the thermal insulation covers (removed on first EVA) onKibo. He then installed twoGPS antennas onKibo's logistics module, while RobertKimbrough installed a new TV camera on the truss. Meanwhile the managers on the ground had decided to extendEndeavour's mission to allow the crews more time to resolve the issues with the Urine Processing Assembly. And the UPA finally appeared to be functioning normally after the modifications performed by the crew on orbit.
The mission's final spacewalk required careful coordination, as the spacewalkers performed preventative maintenance on the station's portSARJ, which currently was functioning well. RobertKimbrough had just the one spacewalk to lubricate the same surface area that was lubricated over three spacewalks on the starboard side.
To make that possible, he and StephenBowen opened covers 6, 7, 10, 11, 14 and 15, and left them open for most of the spacewalk. RobertKimbrough then lubricated the exposed area and moved away so that flight controllers on the ground could rotate the joint 180 degrees. That helped spread the grease, and expose new, unlubricated areas under the open covers.
While the joint was rotating, RobertKimbrough returned to theQuest airlock to retrieve a video camera. He installed the camera on the first port segment of the station's truss, where it will be used next year to provide views of the robotic arm's capture and docking of the first Japanese H-2 Transfer Vehicle.
RobertKimbrough then moved back to the portSARJ, greased the newly exposed areas and closed the covers.
Meanwhile, StephenBowen worked on several projects at the JapaneseKibo module. He reinstalled the common berthing mechanism's insulation that he removed during the first spacewalk. Next, he tucked in the module's robotic arm grounding tabs, which are obscuring the view of the arm's camera, by wrapping the tabs around a cable and Velcroing them together.
Afterward, StephenBowen installed three spacewalk handrails, two worksite interfaces and two Global Positioning Satellite (GPS) antennae onKibo's exterior. The H-2 Transfer Vehicle will use theGPS antennas to navigate to the space station.
Both astronauts wrapped up the spacewalks by taking photographs. StephenBowen photographed the radiators on the first port and starboard truss segments, using both regular and infrared cameras. In September 2008, ground controllers noticed damage to one panel of the starboard radiator.
Blemishes have been noticed on the trailing umbilical system cable of the mobile transporter, so RobertKimbrough was asked to photograph it as well. The photographs were used by teams on the ground to determine the cause of the damage and blemishes and decide what action, if any, should be taken.

On November 26, 2008 DonaldPettit and RobertKimbrough used the station'sCanadarm2 to move Leonardo from theHarmony module and placed in the shuttle's cargo bay at 21:52UTC. HeidemarieStefanyshyn-Piper packed up equipment and supplies used for the four spacewalks and moved them toEndeavour for return, while SandraMagnus continued work on the station's new regenerative life support system. She drained a condensate collection tank to create the optimum ratio of condensate and distillate from the Urine Processor Assembly (UPA), and gathered additional water samples for testing.

On November 28, 2008STS-126 undocked from theISS and moved to a distance of about 450 feet (137.2 meters), where EricBoe began to fly around the station.
OnceEndeavour completed 1.5 revolutions of the complex, EricBoe fired Endeavour's jets to leave the area. The shuttle moved about 46 miles (74 km) 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-01M was launched at 12:38UTC on November 26, 2008. Immediately after launch, an antenna used by the spacecraft's Kurs docking system failed to deploy. The antenna was successfully deployed about three hours later after flight controllers resent the deployment command, however the spacecraft was docked using the backup TORU system, controlled by cosmonaut YuriLonchakov, as a precaution. Following a four-day free flight, it docked withPirs module of theISS at 12:28UTC on November 30, 2008.Progress M-01M carried 2,423 kilograms (5,342 lb) of cargo, consisting of which 820 kilograms (1,810 lb) of fuel, 210 kilograms (460 lb) of water, and 1,343 kilograms (2,961 lb) of dry cargo. The dry cargo included Japanese food for KoichiWakata, who arrived aboard the station in March 2009 as part of Expedition 18. It remained docked until February 06, 2009, when it undocked at 04:10UTC. It subsequently spent two days in free flight, before being deorbited, and burning up in the atmosphere at 08:19UTC on February 08, 2009.

The first stationEVA by MichaelFincke and YuriLonchakov occurred on December 23, 2008 (5h 38m) to deploy and retrieve several Russian experiments on the station's exterior and installing a device to measure electromagnetic forces imparted on station hardware as the complex moves through low Earth orbit. They installed a Langmuir probe onPirs to measure electromagnetic energy to determine its effects on pyrotechnical separation bolts on Soyuz. MichaelFincke removed Biorisk experiment canister from outside ofPirs, and he and YuriLonchakov put it back inside the airlock. They then installed the two new experiments, Expose-R and Impulse, onZvezda. Conducted by ESA, Expose-R, like the Biorisk experiment, exposed biological substances to outer space. Impulse measured disturbances in the ionosphere surroundingISS. They were able to connect both experiments in spite of having trouble with some stubborn cables. Moscow flight controllers relayed that the Impulse experiment was functional but they did not receive telemetry from Expose-R. Therefore, they ordered the pair to disconnect Expose-R and bring it back with them toPirs.

Progress M-66 was launched at 05:49UTC on February 10, 2009. This was the first time Site 31 had been used for aProgress launch sinceProgress M-15 in 1992. The spacecraft docked with thePirs module of theISS at 07:18UTC on February 13, 2009.Progress M-66 delivered supplies to the International Space Station, including fuel, food and water for the crew, and equipment for conducting scientific research and establishing a 6-man crew capacity aboard theISS. It also carried a newOrlan-MK spacesuit to replace one of the olderOrlan-M suits previously used forEVA's from the station. The freighter undocked at 15:18 on May 06, 2009, to make way forProgress M-02M. It was deorbited at 14:28:30 on May 18, 2009 following twelve days of free flight, during which it conducted experiments as part of the Plazma-Progress program. Any debris fromProgress M-66 that survived re-entry landed in the Pacific Ocean at around 15:14:45UTC.

The second and finalEVA was performed again by MichaelFincke and YuriLonchakov on March 10, 2009 (4h 49m). They brought the Expose-R experiment back toZvezda, re-attempting to install it. This time the installation was a success. They also removed tape onPirs' docking target and docking compartment to ensure that it would not interfere with the arrival ofSoyuz or other spacecraft. The pair concluded their walk by taking photographs of the exterior of the Russian portion ofISS. This was to assess the current condition of the Station's surface and its mechanical components after having been exposed to the harsh environment of space for 10 years.

On March 12, 2009, a piece of debris from the upper stage of a Delta II rocket used to launch aGPS satellite in 1993, passed close to theISS. The conjunction between the debris and the Space Station was not detected until it was too late to perform a collision avoidance maneuver. The crew prepared to evacuate the station by closing hatches between modules, and boarding theSoyuz spacecraft that was docked to provide emergency crew escape. The debris did not hit the station, instead it passed by at 16:38UTC, and the crew were cleared to resume operations about five minutes later.

STS-119, the next Space Shuttle docked with the International Space Station on March, 17, 2009.
STS-119 (ISS 15AITS-S6) delivered and assembled the fourth starboard Integrated Truss Segment (S6), and the fourth set of solar arrays and batteries to the station.
KoichiWakata remained on the station, joining Expedition 18 Commander MichaelFincke andFlight Engineer YuriLonchakov. KoichiWakata replaced Expedition 18Flight Engineer SandraMagnus, who returned to Earth with theSTS-119 crew. KoichiWakata served as aFlight Engineer for Expeditions 18 and19. MichaelFincke and YuriLonchakov were launched to the complex in theSoyuz TMA-13 spacecraft on October 12, 2008, from the Baikonur Cosmodrome in Kazakhstan. KoichiWakata returned to Earth on shuttle missionSTS-127, while Michael Fincke and YuriLonchakov returned in theSoyuz in April 2009.

STS-119 delivered the International Space Station's final, major U.S. truss segment, Starboard 6 (S6), providing the power-generating capacity for a six-person crew to conduct increased science activities. With its two Solar Array Wings (SAWs) for converting solar energy into electrical power and a radiator for rejecting heat away from electrical components, theS6 is the final truss element and completes the station's 11-segment Integrated Truss Structure (ITS). Also called a Photovoltaic Module (PVM) because of its ability to generate, store and distribute electrical power to the station, theStarboard 6 segment will ensure the outpost is powered to its intended maximum potential.
A unique feature about theS6 is that it will carry two spare Battery Charge/Discharge Units (BCDUs), used for controlling the charge and discharge of spare batteries on the station. TheS6 segment was modified to carry the additional BCDUs, attached to the segment's Long Spacer Truss structure.
The space station's solar arrays are the largest deployable space assemblies ever built and the most powerful electricity-producing arrays in orbit. Until deployed, each SAW remains folded in a special canister called a Solar Array Assembly (SAA) at the end of theS6 element. In the canister, each wing is equipped with an expandable mast. Two solar array blanket boxes, containing 32,800 solar cells, are connected to the ends of each canister and are restrained to the element frame for launch. The addition ofS6 brings the station's total SAWs to eight. Each wing is 115 by 38 feet (35.1 by 11.6 meters) wide and, when all eight are fully deployed, will encompass an area of 32,528 square feet (3,022 square meters), minus the masts.
The 310-foot (94.5 meters) integrated truss structure to which theS6 will be attached forms the backbone of the space station, with mountings for unpressurized logistics carriers, radiators, solar arrays, and the various elements. The 45-footlongS6 began as an operations test item for its twin sister, thePort 6 truss segment that was launched during Endeavour'sSTS-97 mission on November 30, 2000.
The integrated truss segments started with Starboard 0 (S0) as the center assignment and were numbered in ascending order outward to the port (P) and starboard (S) sides. Starboard is the right side and port is the left side of the truss structure. Zenith (Z) is up, when the station is flying in its normal orientation. At one time, there was an S2 and a P2 planned, but they were eliminated when the station design was scaled back. FromS0, the truss segments areP1,P3,P4,P5 andP6 andS1,S3,S4,S5 andS6.P6 is attached toP5, and once in orbitS6 was attached toS5. TheS6 primary structure is made of a hexagonal-shaped aluminum structure and includes four bulkheads and six longerons, which are beams that connect the bulkheads.
During theSTS-119 mission,S6 was removed from the payload bay with the space station's robotic arm because the shuttle's arm is unable to remove the element with the current configuration of the station. TheS6 element then was handed to the shuttle arm and maneuvered to another location, while the station arm changed base points. TheS6 then was handed back to the station arm and maneuvered to an overnight park position. Removing the truss from the payload bay and maneuvering to an overnight park position took an entire day. The following day the truss was installed during a planned spacewalk. Once the final truss segment was attached,S6 supported power generation and energy storage, utility routing, power distribution and Orbital Replacement Unit (ORU) storage.
Major subsystems of theS6 truss are the starboard outboard Photovoltaic Module (PVM), the Photovoltaic Radiator (PVR), the Long Spacer Truss (LST) and the Modified Rocketdyne Truss Attachment System (MRTAS). TheS6 PVM includes all equipment outboardS5, namely the two Photovoltaic Array Assemblies (PVAAs) and the Integrated Equipment Assembly (IEA). The PVR provides thermal cooling for the IEA. The MRTAS is used to provide a structural interface to theS5 truss element. Each PVAA consists of a SAW and Beta Gimbal Assembly (BGA).
S6 was the fourth and final of the four PVMs that convert sunlight to electricity in orbit. The primary functions of the power module are to collect, convert, store, and distribute electrical power to loads within the segment and to other station segments. Electrical power is a critical resource for the station because it allows astronauts to live comfortably, safely operate the station and perform complex scientific experiments. Since the only readily available source of energy for spacecraft is sunlight, technologies were developed to efficiently convert solar energy to electrical power.
The PVMs use large numbers of solar cells assembled onto solar arrays to produce high power levels.NASA and Lockheed Martin developed a method of mounting the solar arrays on a "blanket" that can be folded like an accordion for delivery to space and then deployed to its full size once in orbit. The cells are made from purified crystal ingots of silicon that directly convert light to electricity for immediate use through a process called photovoltaics.
Gimbals are used to rotate the arrays so that they face the sun to provide maximum power to the space station. After the conversion process, the PVMs also use the electricity to recharge onboard batteries for continuous sources of electricity while the station is in the Earth's shadow. Once complete, the station power system, consisting of U.S. and Russian hardware and four photovoltaic modules, will use between 80 - 100 kilowatts of power or about as much as 42 average houses (defined as 2,800 square feet of floor space using 2 kilowatts each). Some of the electricity is needed to operate space station systems, but once that is figured in, the addition of theS6 will nearly double the amount of power available to perform scientific experiments on the station - from 15 kilowatts to 30 kilowatts.
There are two SAWs on theS6 module, each deployed in the opposite direction of the other. Each SAW is made up of two solar blankets mounted to a common mast. Before deployment, each panel is folded accordion style into a Solar Array Blanket Box (SABB) measuring 20 inches (51 centimeters) high and 15 feet (4.6 meters) in length. Each blanket is only about 20 inches (51 centimeters) thick while in this stored position. The mast consists of interlocking battens that are stowed for launch inside a Mast Canister Assembly (MCA).
When deployed by the astronauts, the SAW unfolds like an erector set. Like a human torso, it has two arms when mounted onS6, and they are rotated outwards by astronauts during a spacewalk so they can be fully deployed. Because these blankets were stored for such a long time, extensive testing was conducted to ensure they would unfold properly in orbit so the blankets would not stick together.
When fully deployed, the SAW extends 115 feet (35.1 meters) and spans 38 feet (11.6 meters) across and extends to each side of the Integrated Equipment Assembly. Since the second SAW is deployed in the opposite direction, the total wing span is more than 240 feet (73.2 meters).
Each SAW weighs more than 2,400 pounds (1,089 kg) and uses 32,800 solar array cells, each measuring 8 centimeters square with 4,100 diodes. The individual cells were made by Boeing's Spectrolab and Aviation Systems Engineering Co. There are 400 solar array cells to a string and there are 82 strings per wing. Each SAW is capable of generating 32.8 kilowatts, or about 10.5 to 15 kilowatts of usable power. There are two SAWs on theS6 module capable of delivering a combined 21 to 30 kilowatts of usable power per PVM with a total of four PVMs on the station.
The solar arrays produce more power than can be made available to the station's systems and experiments. Because all or part of the solar arrays are eclipsed by the Earth or station structure at times, batteries are used to store electricity for use during those periods. About 60 percent of the electricity generated is used to recharge the batteries. During long eclipse periods, power availability is limited to about 10.5 kilowatts from each SAW, or 30 kilowatts per PVM. During shorter eclipse periods more power is available to station systems and experiments. Circuit breakers also regulate the flow of electricity to prevent overheating of the Utility Transfer Assembly (UTA) that allows power to flow through the rotatingSARJ.
When theS6 truss is attached to theS5 short spacer, it will be positioned outboard of the starboardSARJ, which is designed to continuously rotate to keep theS4 andS6 solar array wings oriented toward the sun as the station orbits the Earth. Located betweenS3 andS4, the starboardSARJ is a 10.5-foot (3.2 meters) diameter rotary joint that weighs approximately 2,500 pounds (1,134 kg). TheSARJ can spin 360 degrees using bearing assemblies and a servo control system to turn. Due to vibrations and damage found on its race ring, the starboardSARJ has been rotated only when needed.STS-126 astronauts cleaned and lubricated the race ring, and preliminary results show the joint is moving more freely. The race ring has a triangular cross-section on which 12 bearings roll. All of the power flows through the Utility Transfer Assembly (UTA) in theSARJ. Roll ring assemblies allow transmission of data and power across the rotating interface so it never has to unwind.
The solar array wings also are oriented by the BGA, which can change the pitch of the wings by spinning the solar array. The BGA measures 3 x 3 x 3 feet (92 x 92 x 92 centimeters) and provides a structural link to the Integrated Equipment Assembly (IEA). The BGA's most visual functions are to deploy and retract the SAW and rotate it about its longitudinal axis. The BGA consists of three major components: the Bearing, Motor and Roll Ring Module (BMRRM), the Electronics Control Unit (ECU) and the Beta Gimbal Transition Structure, mounted on the BGA platform. The Sequential Shunt Unit (SSU) serves to manage and distribute the power generated from the arrays and is also mounted on each BGA platform.
Both theSARJ and BGA are pointing mechanisms and mechanical devices used to point the arrays toward the sun. They can follow an angle target and rotate to that target in the direction toward the sun. Controllers in orbit continuously update those targets so they keep moving as the station orbits the Earth every 90 minutes, maintaining the same orientation toward the sun at the same orbital rate. TheSARJ mechanism rotates 360 degrees every orbit, or about 4 degrees per minute, whereas the BGA moves only about four or five degrees per day.

About two hours afterDiscovery attached to the forward docking port at the end of the station'sHarmony module, hatches were opened between the two spacecraft to allow the 10 crew members to greet one another for the start of joint operations. Following a standard safety briefing by MichaelFincke, the crews went to work, activating a Station-to-Shuttle Power Transfer System that provided additional electricity to Discovery for the longer operation of shuttle systems.
A few hours after hatch opening, Sandra Magnus and KoichiWakata exchanged custom-made RussianSoyuz spacecraft seat liners. With that exchange, KoichiWakata became a member of the Expedition 18 space station crew and SandraMagnus became part ofDiscovery's crew.

The firstEVA by StevenSwanson and RichardArnold occurred on March 19, 2009 (6h 07m). AfterCanadarm2 was releasedS6 and moved away, the spacewalkers plugged in power and data cables to connect the new hardware. The two spacewalkers also removed launch locks, stowed a keel pin, removed and jettisoned four thermal covers, and deployed the blanket boxes that hold the solar arrays in place during launch.
The first spacewalk of the mission was devoted to installing the station's new truss segment and preparing the segment's solar arrays for unfolding on the eighth day of the mission. StevenSwanson and RichardArnold moved to theS5 - or Starboard 5 - segment of the truss and made sure that the station's robotic arm had the newS6 truss segment in the correct position for its installation. It should be about 150 centimeters (4.9 feet) from the end of theS5 truss.
From the robotic arm workstation inside theDestiny laboratory, JohnPhillips then moved the segment to a point 30 centimeters (11.8 inches) away from the end of theS5 truss, while StevenSwanson and RichardArnold monitored clearances to ensure proper alignment. On their "go", JohnPhillips moved the segment to 15 centimeters (about 6 inches) for another check before making contact.
Assuming everything is correctly aligned, RichardArnold engaged a capture latch to allow the station's truss to support the new segment, rather than the robotic arm. Then StevenSwanson tightened the four bolts that attached the segment to the station, and RichardArnold attached fourS6 grounding straps toS5.
WithS6 safely attached toS5, Steven Swanson and RichardArnold began hooking up the four connections that will allow power and data to pass from one segment to the other. After that, StevenSwanson and RichardArnold split up. RichardArnold released the restraints holding the blanket box that contained the solar array blankets, so that the arrays could be unfolded later.
StevenSwanson, meanwhile, had two tasks. First, he prepared theS6 radiator panels to be unfolded. He removed the six cinches that keep the panels folded together, and removed two pins that prevent them from unfolding. Afterward, flight controllers at the Mission Control Center in Houston were able to command the radiator to unfold.
StevenSwanson then moved to the beta gimbal assembly - or BGA - which allows the solar array wings to twist as they track the sun. The BGA is kept from rotating during launch by a keel fastener. StevenSwanson removed the fastener so he could rotate the BGA into place for the unfolding on the solar array wings. After he did, he reinstalled the fastener and removed some launch restraints on the BGA.
StevenSwanson and RichardArnold then were reunited and rotated the blanket boxes into position for the unfolding of the arrays within them. StevenSwanson worked on the two boxes on the bottom, while RichardArnold worked on the two on the top.
Their last tasks were to remove thermal covers from the system's electronic control and sequential control units and jettison them behind the station to burn up in the Earth's atmosphere.

The secondEVA was performed by StevenSwanson and JosephAcaba on March 21, 2009 (6h 30m). First task during this spacewalk was to prepare a worksite for new batteries that will be brought up on the STS-127 mission. They loosened bolts, installed foot restraints. StevenSwanson installed a Global Positioning System antenna on the pressurized logistics module attached to theKibo laboratory. They photographed areas of radiator panels extended from thePort 1 andStarboard 1 trusses and reconfigured connectors at a patch panel on the Zenith 1 truss that power Control Moment Gyroscopes. After struggling with a pin that kept an Unpressurized Cargo Carrier Attachment System (UCCAS) from fully deploying, they tied UCCAS safely in place.
StevenSwanson and JosephAcaba's first task during this spacewalk was to loosen two bolts on the battery on theP6 - or Port 6 - arrays. The battery was replaced during theSTS-127 mission.
From there, they continued working on the port side of the station's truss, on the bottom of theP3 segment, to prepare an unpressurized cargo carrier attachment system for use. The system allows cargo to be attached to the station's truss. To do so, the spacewalkers first removed brackets and pins holding the latch in place, moved the latch into position and then reinstalled the brackets and pins.
Following that task, StevenSwanson worked on repairing a thermal cover over a quick disconnect on the first port segment's radiator beam valve module. JosephAcaba, meanwhile, worked between the first and third port segments to install two fluid jumpers, by disconnecting them from the panels they're currently connected to and reconnecting them on new panels. The two spacewalkers then were reunited at the flex hose rotary coupler onP1 to release clamps holding the hoses down. This prepares the coupler, which transfers liquid ammonia across the joints that allow the station's radiators to rotate, to be replaced at a later date.
After that work was complete, Steven Swanson and JosephAcaba moved to the starboard side of the station's truss to prepare a payload attachment system for use on the top of the outboard side of theS3 segment, in a process similar to preparing the unpressurized cargo carrier attachment system for use. Both systems were used to attach equipment to the station's truss.
The final tasks of the spacewalk were for StevenSwanson to relocate a tool stanchion from the station's zenith truss segment to a worksite on the exterior of theDestiny laboratory, and for JosephAcaba to retrieve a foot restraint on the zenith truss and bring it into the station's airlock.

Flight day 8 was mostly used for a free day, although work on the Urine Processor Assembly continued and they had to avoid a piece of orbital debris (from a former Chinese satellite).

The third and finalEVA by RichardArnold and JosephAcaba was performed on March 23, 2009 (6h 27m) to move one of the station's two Crew and Equipment and Translation Aid - orCETA - 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. TheCETA cart also got a new coupler. TheEVA also included lubricating the end effector capture snares on the station's robot arm - similar to what was done to the other end on anSTS-126 spacewalk in late 2008. This has been proven to prevent the snare from snagging or not returning snugly into its groove inside the latching mechanism.
RichardArnold prepared the cart to be moved fromP1 toS1 by releasing its brakes and wheel bogies. JosephAcaba carried it to its new home onS1 aboard the station's robotic arm. RichardArnold then moved to the site and was ready to help RichardArnold reinstall the cart.
RichardArnold then took his turn on the station's robotic arm, which maneuvered him into place to work on the station's special purpose dexterous manipulator - also known asDextre - on the exterior of theDestiny laboratory. RichardArnold were re-securing two thermal covers onDextre's orbital replacement unit tool changeout mechanism and removing a thermal cover on one of its electrical platforms.
When he had done with that, he climbed off the robotic arm to lubricate the latching snares on its end effector, the mechanism that allows the arm to hold on to grapple fixtures or equipment. During the previous shuttle mission, the same lubrication was performed on the other end of the robotic arm - the arm has two end effectors, which allows it to move end-over-end to various worksites on the station. The snares have been experiencing some sticky spots that caused kinks in them, and during the previous mission, the lubrication was able to help clear up that problem. RichardArnold used a grease gun to apply the lubrication and used needlenose pliers to maneuver the snares.
While RichardArnold was working onDextre and the robotic arm, JosephAcaba performed several tasks on the starboard truss, mirroring some of the work he and RichardArnold did on the port side of the truss during the second spacewalk. He installed fluid jumpers between theS1 andS3 truss segments and released clamps on theS1 flex hose rotary coupler. He also swapped a bolt bus controller connector on the truss' segment-to-segment attach system.
RichardArnold and JosephAcaba finished the spacewalk by replacing failed remote power control modules on theS0 andP1 truss segments.

They were unable to deploy thePort 3 unpressurized cargo carrier attachment system (UCCAS). They secured the UCCAS in place until engineers can evaluate the problem. Mission Control cancelled the installation of a similar payload attachment system on the starboard side.

On Flight day 11 they had a press conference with President Obama, students and members of the Congress. They also handled final transfers from Discovery to theISS.

On March 25, 2009STS-119 undocked from theISS and moved to a distance of about 450 feet (137.2 meters), where AnthonyAntonelli began to fly around the station.
OnceDiscovery completed 1.5 revolutions of the complex, AnthonyAntonelli firedDiscovery's jets to leave the area. The shuttle moved about 46 miles (74 km) 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.

Bisphosphonates as a Countermeasure to Space Flight Induced Bone Loss (Bisphosphonates) will determine whether antiresorptive agents, or those that help reduce bone loss on Earth, in conjunction with the routine in-flight exercise program, will protect station crew members from the bone loss documented on previous missions.

On March 28, 2009 Russian spacecraftSoyuz TMA-14 brought the two new crewmembers of Expedition 19 to the station. Finally, the station command changed from US astronaut MichaelFincke to Russian cosmonaut GennadiPadalka.
