Atlantis' climb to orbit was flawless, carrying a seven-member crew. Aboard Atlantis are Commander Rick Sturckow, Pilot Lee Archambault, and mission specialists Patrick Forrester, Steven Swanson, John “Danny” Olivas, Jim Reilly and Clayton Anderson.

As Atlantis launched, the International Space Station flew 220 miles above the southern Indian Ocean, southwest of Australia. On the station awaiting Atlantis’ arrival are Expedition 15 Commander Fyodor Yurchikhin and flight engineers Oleg Kotov and Suni Williams. The station crew watched Atlantis’ launch on a video link sent by Mission Control.

Atlantis will link up with the station on Sunday to begin a joint mission that will increase the complex’s power generation capability. Using the shuttle and station robotic arms and conducting three spacewalks, the astronauts will install another set of giant solar array wings on the station and retract another array, preparing it for a future move.

Anderson and Williams will switch places within hours after Atlantis arrives. Anderson will begin a four-month stay on the station. Williams will journey home on Atlantis. Williams has been on the station since December and will return to Earth with a record for the longest female spaceflight in history.

After reaching orbit, Atlantis’ crew began procedures to open the shuttle’s payload bay doors and set up computers and other equipment. They also will power up the shuttle's robotic arm to check its operation. They will use the arm on Saturday to inspect Atlantis’ heat shield. On Sunday, Atlantis is scheduled to dock to the station at about 2:36 p.m. CDT. The shuttle crew begins a sleep period at 12:38 a.m. CDT Saturday and will awaken for their first full day in space at 8:38 a.m. CDT Saturday.

Pilot Lee Archambault and Mission Specialists Patrick Forrester and Steven Swanson used the shuttle’s robotic arm and an extension boom-mounted sensor system to inspect the heat shield on Atlantis’ wing leading edges and nose cap.

Last night the crew used the robotic arm to take a closer look at an area of insulation blanket on the port orbital maneuvering system pod that was seen to be pulled away from adjacent thermal tiles.

Prior to stowing the boom, the crew utilized the added reach to send Mission Control engineers up-close video of the displaced portion of the blanket. It will be analyzed along with the video from Friday night.

In preparation for Sunday’s docking, the crew extended the shuttle’s docking ring and checked out the rendezvous tools. The crew also installed a docking system centerline camera that will be used by Commander Rick Sturckow to align Atlantis with the station’s docking port.

While the robotic arm survey proceeded, Mission Specialists Danny Olivas, Jim Reilly and Clay Anderson checked and prepared the spacesuits they’ll wear during the three spacewalks on the fourth, sixth and eighth days of the mission. The major objective of the spacewalks is to install the station's newest component, the Starboard 3 and 4 (S3/S4) truss segments, unfurl a new set of solar arrays and fold and pack the right side of the Port 6 solar array.

On the space station, Expedition 15 Flight Engineer Suni Williams prepared the orbiting laboratory for Atlantis’ arrival tomorrow. She readied the digital cameras that will be used to take high-resolution photos of the shuttle's heat shield. Commander Fyodor Yurchikhin pressurized the docking port at the back end of the U.S. laboratory, Destiny.

Tomorrow as Atlantis makes its final approach to the station, Sturckow will take control of Atlantis and begin a slow back-flip rotation allowing Yurchikhin and Flight Engineer Oleg Kotov to photograph the shuttle’s heat shield. Williams will videotape the maneuver.

Once the back-flip is complete, Sturckow will maneuver Atlantis to docking, setting the stage for a week of joint operations between the two crews.

After hatch opening and welcome, Anderson will transfer his seat liner to the Soyuz spacecraft and officially become a member of the station’s Expedition 15 crew, joining Yurchikhin and Kotov. Williams, who’s been in space since her launch last Dec. 9, will return home with Atlantis’ crew.

Delivery of the S3/S4 Truss segment, which includes a new pair of giant solar arrays for power generation, begins shortly after docking tomorrow when the shuttle robotic arm is used to lift it from the payload bay and hand it off to the station’s robotic manipulator. Installation of the truss segments occurs Monday in conjunction with the first spacewalk of the mission, conducted by Reilly and Olivas.

“Big Boy Toys” by Aaron Tippin, sounded on board the orbiter at 9:10 a.m. CDT, played for Commander Rick Sturckow. The crew was given an extra half hour to sleep this morning after being kept up late to finish downloading in-cabin video.

Today Pilot Lee Archambault and Mission Specialists Patrick Forrester and Steven Swanson will use the shuttle’s robotic arm to unberth the Orbiter Boom Sensor System (OBSS) for a detailed examination of Atlantis’ thermal protection system. Last night they took a closer look at an area of insulation blanket on the port orbital maneuvering system pod that was seen to be pulled away from adjacent thermal tiles during the robot arm checkout late Friday.

In parallel to today's inspection, Mission Specialists John “Danny” Olivas, Jim Reilly and Clayton Anderson will conduct a thorough checkout of the spacesuits to be worn during the three spacewalks planned for the docked operations at ISS and prepare them and other EVA hardware for transfer to the station.

Later, in preparation for docking, the crew will install a centerline camera, extend the outer ring of the Orbiter Docking System, and check out rendezvous tools. Sturckow is scheduled to fly Atlantis to a docking with ISS at 2:36 p.m. Sunday.

After hatch opening and welcome, Anderson will transfer his seat liner into the Soyuz spacecraft docked to the Zarya module and officially become a member of the station’s Expedition 15 crew, joining Commander Fyodor Yurchikhin and Flight Engineer Oleg Kotov. Flight Engineer Suni Williams, who’s been in space since her launch last Dec. 9, joins the shuttle crew and will return to Earth with them.

Delivery of the S3/S4 Truss segment, which includes a new pair of giant solar arrays for power generation, begins shortly after docking tomorrow when the shuttle robot arm is used to lift it from the payload bay and hand it off to the station’s robotic manipulator. Installation of the truss segments occurs Monday in conjunction with the first spacewalk of the mission, conducted by Reilly and Olivas.

Most of the crewmembers got an 8:08 a.m. CDT wakeup call with the song “It Probably Always Will” by the Ozark Mountain Daredevils, played for Mission Specialist Steven Swanson. Spacewalkers Jim Reilly and John “Danny” Olivas, who spent the night in the Quest airlock under reduced atmospheric pressure to facilitate the purge of nitrogen from their bloodstreams, were allowed to sleep in until 8:38 a.m.

Starting shortly after 10 a.m. Pilot Lee Achambault, Mission Specialist Patrick Forrester and Expedition 15 Flight Engineer Oleg Kotov will use the station’s Canadarm2 to maneuver the S3/S4 Truss to the outboard end of the S1 Truss and into position so that four bolts can be driven to form a hard mate between the two components.

Activation of the new truss segments will be done during the spacewalk starting at 1:53 p.m., when Reilly, designated EV1 and wearing the suit with red stripes, and Olivas, EV2 and wearing a suit with no stripes, emerge from the Quest airlock.

Over the course of the next 6½ hours they will connect power, data and cooling cables between S1 and S3; release the launch restraints from and deploy the four solar array blanket boxes on S4 and release the cinches and winches holding the photovoltaic radiator on S4. They also will rotate the keel pin on S3; rigidize four Alpha Joint Interface Structure struts and install one Drive Lock Assembly on the Solar Alpha Rotary Joint; and remove some of the SARJ launch locks and restraints.

In parallel to those activities the ISS Flight Control Team in Mission Control Houston will begin the commanding to activate the two new power channels and to deploy the new truss’ radiator. The spacewalk is scheduled to conclude at 8:23 p.m. CDT.

While the spacewalk proceeds the newest member of the ISS crew will be learning about his new home on orbit. Flight Engineer Clayton Anderson is scheduled for handover briefings with his predecessor, astronaut Suni Williams, and has unstructured time to facilitate his adaptation to his new surroundings.

The extra power sets the stage for addition of European and Japanese laboratories later this year and early next.

Prior to crew wake up this morning, station controllers began unfurling the solar array attached to the newly installed S3/S4 truss segment. Space Shuttle Atlantis astronauts then took over, unfolding one wing at a time in stages, pausing to let the solar array panels soak up some sun, which helps to prevent the thin individual panels from sticking together. They finished unfolding the first wing at 11:29 a.m. and the second at 12:58 p.m. – both are now capable of generating power.

Tomorrow at about 1 p.m., Mission Specialists Patrick Forrester and Steve Swanson head outside on their first of two spacewalks to remove launch locks from the 10-foot-wide solar alpha rotary joint to free the arrays to rotate and track the sun. During the six-hour spacewalk, the spacewalkers will help flight controllers fold up an older solar array to make room for the rotation. That retracted pair of arrays and corresponding truss segment eventually will be relocated and redeployed to add even more power capability to the station.

Late in the day, the station experienced a problem with a Russian navigation computer that challenged flight controllers in Houston and Moscow to manage the station’s attitude in space. Several methods of attitude control are available – Russian thrusters, Atlantis thrusters, or station electrically-driven gyroscopes.

The crew or station never was in danger throughout the troubleshooting efforts, and the station’s gyroscopes took over attitude control shortly after 8 p.m. That was followed by relocation of the Mobile Transporter in preparation ahead of tomorrow’s spacewalk.

The problem with the navigation computer began when flight controllers attempted to turn attitude control over to the station computers after letting shuttle computers handle it while the arrays were unfolded. The computer would not allow them to do so, and forced a reboot of the main Russian command and control computer, which triggered an alarm enunciating the problem to the crew and ground controllers.

Meanwhile, mission managers still are mulling over the best course of action for repairing a raised corner of a thermal insulation blanket that came loose during launch last Friday. The Mission Management Team elected to wait at least one more day so that engineers could develop detailed plans for a spacewalking task to be carried out during the third or fourth spacewalk (Friday or Sunday).

Ground tests will be performed to understand which repair technique provides the greatest potential for success.

The day began at 8:08 a.m. with the wakeup song “What a Wonderful World” by Louis Armstrong, played for Mission Specialist Danny Olivas. Olivas and Mission Specialist Jim Reilly completed a 6-hour, 15-minute spacewalk yesterday to complete the hardware installation of the S3/S4 Truss segments, which cleared the way for flight controllers to activate the new components.

Overnight ISS flight controllers commanded the initial minimal deployment of both solar array wings. Starting at 10:43 this morning shuttle Commander Rick Sturckow, Pilot Lee Archambault and Mission Specialists Pat Forrester, Steve Swanson, Suni Williams, Olivas and Reilly are scheduled to observe and assist in the complete deployment of those solar arrays to their full 115-foot length.

After lunch the shuttle crewmembers all get a couple of hours off duty before beginning preparations for a spacewalk by Forrester and Swanson tomorrow. They will assist with the initial stages of retraction of the starboard side solar array on the P6 module before removing the remaining launch restraints on the Solar Alpha Rotary Joint on S3/S4. That’s required to permit the SARJ to rotate so the new solar arrays can track the sun while the station orbits the Earth.

The shuttle crew and the Expedition 15 crewmembers, Commander Fyodor Yurchikhin and Flight Engineers Oleg Kotov and Clay Anderson, are awaiting word from the Mission Management Team on the plan for the mission’s third and fourth spacewalks. The MMT extended the mission by two days and added a fourth EVA to provide time to repair the raised thermal blanket on the Orbital Maneuvering System pod. A decision about whether that job will be done on EVA 3 or EVA 4 is expected today.

Mission Specialists Patrick Forrester and Steven Swanson, who camped out in the Quest airlock as part of their spacewalk preparations, and their crewmates were awakened at 8:08 a.m. CDT with “Questions 67 and 68” by Chicago, played for Pilot Lee Archambault.

While Mission Specialists Danny Olivas and Suni Williams help the spacewalkers get ready, the other Atlantis astronauts will be working the early steps of retraction of the 2B solar array wing, on the starboard side of the P6 Truss. Commander Rick Sturckow, Archambault and Mission Specialist Jim Reilly will send commands and monitor the retraction for any repeat of the difficulties with folding panels and sticking guide wires that were encountered on a similar retraction last December.

When Forrester and Swanson exit Quest at 1:03 p.m. they’ll move up the P6 Truss to monitor the retraction and to assist if required. Forrester, who will be in a foot restraint on the station’s robot arm, and Swanson will have specially-prepared tools to use to help the panels of photovoltaic cells fold properly.

After 45 minutes the spacewalkers will move on to the primary job of the day, preparing the Solar Alpha Rotary Joint between the S3 and S4 Truss segments for rotation. Forrester and Swanson will remove all remaining locks and restraints that held the joint safely in place during launch so that the joint is free to rotate, enabling the new solar array wings on S4 to track the sun as ISS orbits the Earth. The spacewalk is scheduled to end at 7:33 p.m.

Expedition 15 Commander Fyodor Yurchikhin and Flight Engineers Oleg Kotov and Clayton Anderson are scheduled to work on the transfer of supplies, and Anderson has time in his schedule for handover briefings and familiarization with his new home in orbit.

Meanwhile, managers approved a repair task for a damaged thermal blanket to be carried out during the next spacewalk Friday.

During the second spacewalk of Space Shuttle Atlantis’ mission, Forrester and Swanson today removed all of the launch locks holding the 10-foot-wide solar alpha rotary joint in place. The spacewalkers had planned to remove the joint’s launch restraints as well, but left them for a later spacewalk.

The spacewalkers ran into a problem when Forrester tried to install a drive-lock assembly and found that commands being sent to it were actually being received by a drive-lock assembly installed during the mission’s first spacewalk. Flight controllers confirmed that the drive-lock assembly installed earlier was in a safe configuration and are working to confirm that the newly installed assembly is as well.

Once fully activated, the drive-lock assemblies engage gears permitting the massive joint to rotate allowing the arrays to track the sun as the station circles the Earth.

To enable it to do so, spacewalkers also had to help retract an older solar array to clear the new array’s path. The process is delicate, as the panels of the solar arrays tend to get caught on their guide wires and fold in the wrong direction. Flight controllers started the retraction before the crew woke up, and were able to get seven and a half of the 31.5 solar array bays folded. Then, on the spacewalk, Forrester and Swanson were able to poke and prod another five and a half bays worth of panels into folding correctly before moving on to other tasks.

The astronauts also were able to make sure the arrays were in a good configuration for another try by flight controllers on Thursday. If necessary, the spacewalkers could provide more hands-on help during one of the mission’s remaining two spacewalks.

Meanwhile, as the second spacewalk continued, mission managers decided that at least part of the third spacewalk, scheduled for Friday, will be dedicated to repairing a raised corner of a thermal insulation blanket that came loose from the shuttle during launch. Mission Specialist Danny Olivas will staple the corner to an adjacent blanket and use pins to secure it to a thermal protection tile.

Russian flight controllers will be working overnight to resolve a problem with the Russian segment computers that provide backup attitude control and orbital altitude adjustments. For now, the station’s control moment gyroscopes are handling attitude control, with the shuttle’s propulsion providing backup.

At 7:39 a.m. CDT Mission Control in Houston played the wakeup song “Indescribable” by Chris Tomlin for Mission Specialist Patrick Forrester, who completed a 7-hour, 16-minute spacewalk with Mission Specialist Steven Swanson yesterday. The crews had been awakened at 6:23 a.m. by a false fire alarm in the Zarya module, which was the result of troubleshooting Russian segment navigation computers which had just been successfully restarted by Mission Control in Moscow.

Beginning at 10:38 a.m. Flight Engineer Clayton Anderson joins Commander Rick Sturckow, Pilot Lee Archambault, Swanson and Mission Specialist Suni Williams to resume commanding the retraction of the solar array wing on the starboard side of the P6 Truss, which was about half retracted yesterday before and during the spacewalk. That job is on the schedule for the latter half of spacewalk 3 on Friday if it is not completed today.

In the meantime Forrester will work with Mission Specialists Jim Reilly and Danny Olivas to review the procedures for that spacewalk. Olivas will get in a foot restraint on the shuttle robot arm to repair the orbital maneuvering system pod thermal blanket that pulled away from the adjacent thermal tiles on launch last week. There is time in the schedule this afternoon for the crewmembers to practice the repair technique, and then this evening to conduct a tagup with spacewalk specialists in Houston before the spacewalkers begin their campout prebreathe protocol in the Quest airlock.

At 8:58 p.m. Sturckow, Archambault, Forrester and Swanson will discuss the progress of their flight in interviews with Fox News Radio and Denver television stations KMGH-TV and KUSA-TV.

The crew’s wakeup call came at 7:41 a.m. CDT with the song “Radar Love” by Golden Earring, played for Mission Specialist Steve Swanson.

Spacewalkers Jim Reilly and John “Danny” Olivas spent the night in the Quest airlock at reduced atmospheric pressure as part of the spacewalk preparation protocol. They’ll go out the door at 12:38 p.m. and Reilly will help Olivas set up to make repairs to a thermal blanket on Atlantis’ port orbital maneuvering system pod that was damaged during the shuttle’s climb to orbit last week.

Supported by the shuttle robot arm, Olivas will push the turned up portion of the thermal blanket back into position, use a medical stapler to secure the layers of the blanket, and pin it in place against adjacent thermal tile.

At the same time, Reilly will install a hydrogen vent valve in the forward section of the Destiny laboratory for a new oxygen generating system being installed there. The system separates water into its chemical components of oxygen and hydrogen, venting the hydrogen overboard and supplying the oxygen for the station crewmembers to breathe.

When they complete those tasks the spacewalkers will move to the top of the P6 Truss to assist in retraction of the remaining 15 mast bays of the starboard side solar array wing. Armed with tools specially designed for the task, Reilly and Olivas will keep the solar panels folding properly and unstick any stuck grommets on guide wires as their crewmates command the mast to retract. If they’re able to get the array completely retracted, Reilly and Olivas have a list of other jobs to do before ending the spacewalk.

Russian flight controllers are still troubleshooting a problem with Russian computers that provide backup attitude control and orbital attitude adjustment for the station’s control moment gyroscopes. Commands were sent early this morning to start the computers but only one lane of the central computer booted up; all three lanes of both the central computer and the terminal computer were deactivated just before 5 a.m. CDT. The current plan is to leave them turned off today while the teams in the Russian Mission Control Center compare notes and develop a forward plan of action. The station remains in a safe configuration, with attitude control handled by its control moment gyroscopes.

Mission Specialists Jim Reilly and Danny Olivas worked outside the station for 7 hours, 58 minutes and completed all their planned tasks. Olivas spent two hours stapling and pinning down a thermal blanket on Atlantis’ orbital maneuvering system pod. A 4-by-6-inch corner of the blanket peeled up during the shuttle’s launch last week.

Meanwhile, Reilly installed the hydrogen vent valve of a new oxygen generation system on the Destiny laboratory. The system will separate oxygen from water to provide breathing air, while dumping the remaining component – hydrogen – overboard.

When those tasks were completed, the two astronauts joined forces with their colleagues inside the shuttle and station and flight controllers in Houston to complete the delicate process of folding an older solar array so that it can be moved from its temporary location to its permanent home during a shuttle mission this fall.

Armed with lessons learned from last December’s shuttle mission when the other half of the array posed an identical challenge, the STS-117 mission team followed well-trained procedures to retract the array into its protective box. The retraction was completed and latches closed at 7:40 p.m. (7 hours, 15 minutes into the spacewalk). Reilly and Olivas provided hands-on assistance throughout the process.

The retraction sequence today required 28 commands, bringing the total for the retraction to 45.

Behind the scenes while the spacewalk was ongoing, Russian flight controllers were troubleshooting two Russian computers that provide backup attitude control and orbital altitude adjustments for the station’s control moment gyroscopes. Station commander Fyodor Yurchikhin and Flight Engineer Oleg Kotov were able to get two of three lanes in both computers up and running after bypassing with external cabling what appeared to be a faulty power switch.

The computers are now being monitored for proper operation, awaiting additional data evaluation overnight when the station passes over Russian ground stations for detailed telemetry downlink. Each computer requires only one lane running to perform its duties.

One final spacewalk is planned for Sunday, when Mission Specialists Patrick Forrester and Steve Swanson will perform get-ahead tasks and finish preparing the Solar Alpha Rotary Joint for activation. Its function is to allow a new pair of solar arrays to track the Sun as the station circles the Earth.

The crew will spend part of Saturday getting ready for the last spacewalk and discuss the mission during the traditional news conference at 6:43 p.m.

During a news briefing from the Johnson Space Center Saturday afternoon, International Space Station Program Manager Michael Suffredini said, “We’re having a great day on orbit today.”

Yesterday, station Commander Fyodor Yurchikhin and Flight Engineer Oleg Kotov were able to reenable four of the six channels in the computer systems after bypassing what appears to be a faulty power switch with external cabling.

The Russian cosmonauts repeated that same modification today on the last two channels, which were originally suspected to have failed. They are continuing to checkout and troubleshoot the computers. Meanwhile, the forward plan is to keep the original four channels active and keep the other two channels in "stand by" mode.

Engineering teams also plan to test the Russian attitude control system as early as Sunday morning, in order to confirm that it is operating and working well in concert with the U.S. system. The specifics of the test are still being defined but once executed, the teams will determine when shuttle Atlantis will depart the station. Undocking is currently scheduled for Tuesday morning.

Onboard, the rest of the crew today focused on transfer activities as well as preparations for a fourth spacewalk tomorrow. The ten astronauts, including Expedition 15 Flight Engineer Clay Anderson, and shuttle Commander Rick Sturckow, Pilot Lee Archambault, and mission specialists Pat Forrester, Steven Swanson, Danny Olivas, Jim Reilly and Sunita Williams, also participated in a joint crew news conference.

During their crew sleep, Williams established a new record for the longest single spaceflight by a female. At 12:47 a.m. CDT, Williams surpassed the longstanding 188 day and 4 hour record set by astronaut Shannon Lucid at the Mir space station in 1996.

“I was just in the right place at the right time,” said Williams of the record. “It’s an honor to be here.”

The four spacewalkers spent time working on the U.S. spacesuits. Olivas and Reilly finished their post-spacewalk spacesuit reconfiguration tasks, while Forrester and Swanson configured their suits and tools for their second spacewalk. The final spacewalk of the flight is set to begin Sunday morning at 11:33 a.m. CDT.

The spacewalk will include a few wrap up tasks associated with the new truss segment, including installation of the Drive Lock Assembly 2, which with a second DLA, drives rotation of the S3/S4 Truss Solar Alpha Rotary Joint. The spacewalkers also will remove the final six launch restraints on the SARJ to enable its rotation and remove a keel pin and drag link from S3. They’ll also complete installation of a debris shield on the Destiny laboratory, install a computer network cable on Unity and remove a Global Positioning System antenna.

At 12:47 a.m. CDT, Astronaut Suni Williams’ time in space since her launch last Dec. 9 reached 188 days and 4 hours, matching the mark for the longest single spaceflight ever by a woman space traveler. That mark was set by Astronaut Shannon Lucid on her flight to the Mir space station in 1996.

The wakeup call featuring the University of Texas at El Paso Fight Song, performed by the UTEP Pep Band, was played for Mission Specialist (and UTEP alumnus) John “Danny” Olivas at 7:38 a.m. CDT.

Today the four spacewalkers will spend time configuring the spacesuits and EVA tools used on Friday’s 7-hour, 58-minute EVA by Olivas and Mission Specialist Jim Reilly, and then preparing the Quest airlock for Sunday’s spacewalk by Mission Specialists Patrick Forrester and Steven Swanson.

The plan for EVA 4 includes verification of Drive Lock Assembly 2, one of a pair of mechanisms which will drive rotation of the S3/S4 Truss Solar Alpha Rotary Joint, and removal of the final launch restraints on the SARJ to enable its rotation so the solar arrays on S4 can track the sun. The spacewalkers will also remove a keel pin and drag link from S3, complete bolting down a piece of debris shielding on the Destiny laboratory, install a computer network cable on Unity, and remove a Global Positioning System antenna.

Crewmembers will spend time today transferring supplies between ISS and Atlantis, and at 5:18 p.m. will review the timeline for Sunday’s spacewalk. At 6:43 p.m. all 10 astronauts and cosmonauts get together in the Destiny laboratory for the Joint Crew News Conference.

Mission Control Moscow restarted the Russian computers that provide backup attitude control and orbital attitude adjustment for the station’s control moment gyroscopes Friday afternoon and confirmed that they were stable. This morning the Russian flight controllers began sending commands to restart some systems in the Russian segment of ISS.

The Russian central computer is now communicating with the U.S. command and control computer, and the Russian terminal computer is again talking to the U.S. navigation computers. Additional commanding and systems restarts are anticipated today as Russian specialists pore over operations data from the two computers.

The crew’s wakeup call came at 6:38 a.m. CDT with the theme song from “Band of Brothers,” played for Mission Specialist Jim Reilly.

Spacewalkers Patrick Forrester and Steven Swanson begin their second EVA of the flight at 11:33 a.m., with Reilly choreographing the excursion from the shuttle flight deck. Flight Engineer Oleg Kotov will shadow Reilly as intravehicular crewmember, training to take that role for an upcoming station spacewalk.

The first task is to retrieve a TV camera stand from a stowage platform attached to Quest and install it on the S3 truss. From there the spacewalkers will move to the intersection of the S3 and S4 trusses to prepare the Solar Alpha Rotary Joint for rotation. Forrester will verify the installation of a second Drive Lock Assembly, the machine that turns the S4 truss so its solar array wings can track the sun. He will then help Swanson remove the last six SARJ launch restraints to free the joint to turn.

To clear the path on S3 for the Mobile Base System, Forrester and Swanson will remove temporary rail stops and the hardware that secured the S3/S4 in the shuttle payload bay. Then, they will translate back to the body of the station for a few get-ahead tasks.

As time permits, the spacewalkers plan to install a computer network cable on the Unity node, remove a Global Positioning System antenna, tighten the gimbal locks on the S-band Antenna Support Assembly, open the hydrogen vent valve on the Destiny laboratory that was installed on Friday’s spacewalk, and secure the orbital debris shield panel. Today’s spacewalk is scheduled to conclude at 6:03 p.m.

The Russian central computer and terminal computers continue in stable operation, each running on two of its three channels with the third in standby. Mission Control in Moscow has restarted all Russian systems except the Elektron, which is receiving power but not moded to generate oxygen, and is planning to fire Russian attitude control thrusters in conjunction with a maneuver of the mated stack to a water dump attitude on Monday.

The spacewalk was the 87th in support of station assembly and maintenance, the 59th staged out of the station and the 36th out of the Quest airlock. Eleven spacewalks have been completed this year and 14 remain.

Forrester and Swanson began the spacewalk at 11:25 a.m. The two made quick work of retrieving a TV camera and its support structure from a stowage platform attached to Quest and installing it on the S/3 truss. They then verified the Drive Lock Assembly (DLA) 2 configuration and removed the last six Solar Alpha Rotary Joint (SARJ) launch restraints.

Inside, Mission Specialist Jim Reilly choreographed the outside work from the shuttle flight deck, shadowed by Expedition 15 Flight Engineer Oleg Kotov who will assume that role for the July 20 spacewalk by Clay Anderson and Fyodor Yurchikhin.

By 3:17 p.m., the two had cleared the path on S3 for the Mobile Base System by removing temporary rail stops and hardware that had secured the S3/S4 in the shuttle’s payload bay, thus completing the major tasks slated for the STS-117 mission. The spacewalkers then began some of the get-ahead tasks mission managers had hoped to complete.

The two spacewalkers also installed a computer network cable on the Unity node, opened the hydrogen vent valve on the Destiny laboratory that was installed on Friday’s spacewalk, and tethered two orbital debris shield panels on the station’s service module.

Tomorrow morning at approximately 9:28 a.m., Mission Control in Moscow plans to fire Russian attitude control thrusters. The thrusters have not been used since the Russian central computer and terminal computer went down earlier in the week. Those computers continue in stable operation.

Also tomorrow, astronauts onboard Atlantis will have a much deserved day off, bidding farewell to the Expedition 15 crew and closing the hatch between the two vehicles at 5:23 p.m. Atlantis will undock from the station at 9:42 a.m. CDT Tuesday, circling the orbiting complex once as it departs.

Today’s wakeup call came at 5:38 a.m. CDT with “Feelin’ Stronger Every Day” by Chicago, played for Pilot Lee Archambault. Expedition 15 Commander Fyodor Yurchikhin and Flight Engineers Oleg Kotov and Clayton Anderson were awakened on board ISS at the same time.

At 7:45 a.m. Archambault and Mission Specialist Patrick Forrester will begin powering on shuttle systems that have been turned off to conserve power during the docked phase of the flight, and at 8:28 Mission Specialists Steven Swanson and Jim Reilly will set up the centerline camera in the orbiter docking system.

At 9:42 a.m. the hooks and latches holding Atlantis and ISS together will release, and springs in the ODS will push the shuttle away. Archambault will fire shuttle thrusters to move 450 feet in front of the station before starting a full flyaround at 10:07 a.m. to get a good look at the reconfigured spacecraft.

At 11:25 a.m. another firing of Atlantis’ thrusters will begin the final separation of the two spacecraft for this flight. At a range of 46 miles Archambault, Forrester and Swanson will use the shuttle robot arm to lift the Orbiter Boom Sensor System from the starboard payload bay sill and conduct a late inspection of the thermal protection system on both wings and the orbiter’s nose cap.

Today and tomorrow Mission Specialist Suni Williams, in the 192nd day of her spaceflight, will be scheduled for more exercise to help prepare her for Thursday’s scheduled landing at the Kennedy Space Center, when her body will feel the pull of gravity for the first time since her launch last December.

Commander Rick Sturckow, Pilot Lee Archambault, and Mission Specialist and Flight Engineer Steven Swanson checked out Atlantis’ hydraulic systems and flight control surfaces beginning at 8:58 a.m. today. That was followed closely by the steering jet tests at 10:08 a.m.

All seven astronauts spent the day stowing equipment for the landing, and then came together just after 2 p.m. to discuss their mission with NBC, ABC and CNN. The crew is scheduled to go to sleep at 8:38 p.m. and wake up at 4:38 a.m. Thursday.

The Mission Management Team worked into the early evening to ensure the shuttle is safe for landing. Some fuzz from a gap filler poking out on the outer edge of the left wing was noticed during Tuesday’s late inspection and deemed safe for reentry based on its location and measured protrusion of about 4/10 of an inch. Also, the MMT reviewed additional data presented on the thermal blanket damaged during launch on June 8. The blanket was repaired during the third spacewalk of the mission and cleared for reentry.

Discussions centered around thermal models developed by engineers to assess whether any damage may have occurred to underlying structure, but photographs taken by Danny Olivas – who affected the repair – clearly showed no heat effects.

Entry Flight Director Norm Knight indicated that the Kennedy Space Center, Florida, would be the only landing site considered Thursday, based on consumables that provide flexibility to land as far out as Sunday. The weather forecast shows a chance of rain showers within 30 miles of the runway at landing time with a cloud deck at 5,000 feet – both are landing violations. The plan calls for a deorbit engine firing at 11:50 a.m. for the 12:55 p.m. landing and a 1:25 p.m. deorbit burn for the 2:30 p.m. landing opportunity.

If landing is moved to Friday, two landing opportunities would be available in Florida and two in California at the Edwards Air Force Base. Three sites would be available Saturday in order of preference – Florida, California or at White Sands Space Harbor in New Mexico.

The astronauts’ wakeup call came at 5:08 a.m. with “If I Had $1000000” by Barenaked Ladies, played for Mission Specialist Suni Williams, who’s in the 193rd day of her spaceflight.

The entire crew will be involved in routine deorbit preparations by 8:10 a.m., starting by stowing items in the crew cabin.

At 8:58 a.m. Commander Rick Sturckow, Pilot Lee Archambault, and Mission Specialist and Flight Engineer Steven Swanson will power up one of the auxiliary power units and conduct a checkout of the orbiter’s flight control surfaces, and at 10:08 a.m. begin a test firing of each of Atlantis’ reaction control system jets to ensure that both systems are ready for deorbit and landing. All seven crew members gather for a deorbit briefing at 11:28 a.m.

The shuttle astronauts take a break from packing at 2:03 p.m. to talk about the flight in interviews with NBC News, ABC News and CNN Live, then return to packing up for landing. The schedule calls for stowage of the Ku-band communications antenna at 5:58 p.m., just before Mission Specialist Jim Reilly and Williams set up a recumbent seat on the middeck for Williams to use during entry and landing.

The International Space Station’s crew is enjoying a day off duty as they shift their sleep cycle. Expedition 15 Commander Fyodor Yurchikhin and Flight Engineers Oleg Kotov and Clay Anderson are scheduled to go to sleep at 4:30 p.m. and get up at 1 a.m. tomorrow, returning to the normal station wakeup time.

It was the 51st shuttle mission to end with a landing at the Edwards Air Force Base in California.

Atlantis touched down on concrete runway 22 at 2:49:38 p.m. concluding a 13 day, 20 hour, 12 minute flight. NASA’s 747 Shuttle Carrier Aircraft will deliver Atlantis back to Florida in about a week so that it can be prepared for a December flight carrying the next laboratory module to the station on behalf of the European Space Agency.

The crew spent the morning in the world’s largest holding pattern as flight controllers kept a close eye on weather. Showers, thunderstorms and low clouds at Kennedy Space Center knocked Florida out of the running on both the first and second landing opportunities of the day, so flight controllers took their first chance at Edwards, where weather was pristine.

Atlantis crew members, Commander Rick Sturckow, Pilot Lee Archambault, and Mission Specialists Patrick Forrester, Steven Swanson, Danny Olivas, Jim Reilly and Sunita Williams, who is returning home after 194 days, 18 hours, 58 minutes in space, will return to Houston on Saturday. A welcoming ceremony for the crew's return to Houston is planned for 4:15 p.m. Saturday at NASA Hangar 276 at Ellington Field.

During Atlantis’ mission to the International Space Station, the crew performed four spacewalks during which they worked with the station crew to build the station into a near-symmetrical configuration, adding a new starboard truss segment and solar array pair, while folding another array in preparation for its relocation later this year.

Atlantis also delivered Clay Anderson, the station’s newest flight engineer, who will spend the next six months living and working on the station.

The next shuttle mission, targeted for early August, will see the return to flight of space shuttle Endeavour to deliver another segment of the station’s truss and 5,000 pounds of food, clothing, supplies and spare parts. Endeavour’s last mission was in December 2002.
