 and arrived at the launch pad at 16:22 EST. At 4:30 pm, the crew began ingress into the orbiter, and by 17:25 EST, all crewmembers were in their seats and performed communications checks with the ground control personnel. At 18:00 EST, the closeout crew closed and locked Endeavours hatch, and the orbiter's cabin was pressurized in preparation for launch. Despite a last minute issue with the white room closeout door not being fully secured, NASA Launch Director Mike Leinbach polled the team, determined the door did not pose a hazard to the orbiter or crew, and told the crew "Good luck, Godspeed and have a happy Thanksgiving in orbit." Endeavour lifted off on time at 19:55:39 EST (00:55 UTC). External tank separation occurred at 01:03 UTC.

After reaching orbit, the crew began working through the post-insertion timeline, which included opening the orbiter's payload bay doors, deploying the Ku band

 (OBSS), the crew took detailed images of the exterior of the orbiter for the image analysis team to review. The crew also continued to prepare for docking with the station on Sunday, by extending the docking ring, installing the centerline camera, and organizing the tools needed for rendezvous with the station. The crew also performed a checkout of the spacesuits that will be used for the spacewalks during the mission.

During the Mission Management Team briefing, LeRoy Cain noted that upon initial review of the ascent imagery, a small piece of thermal blanket appeared to come loose under the left Orbital Maneuvering System (OMS) pod, but explained that the area is not in an area of concern, as it does not experience high heat during reentry. During the Mission Status briefing, lead Flight Director Mike Sarafin said that after having the crew focus the camera on the left OMS pod, it did not appear that there was any damage, but the image analysis team would take a closer look at the area.

Two issues with the orbiter's Ku antenna were noted by Cain, although he stated they would not impact the mission. The antenna was not handing over from Ku to S-band automatically as it should, which meant that teams on the ground had to manually switch the antenna from Ku to S Band and back again. Sarafin noted that this was likely a software issue, and would not affect the crew on board, or the mission. The other issue had to do with the antenna's failure to "lock on" to satellite targets after being given the pointing data. Instead, the antenna was drifting, which meant that the teams on the ground would have to use an alternate method of pointing the antenna. There was a possibility that the shuttle crew would need to use a backup procedure during rendezvous with the station, but it was not a concern, and would not change the timeline, Cain noted.

16 November (Flight day 3)

After waking up, the crew set to work preparing for the rendezvous and docking with the station. The orbiter performed a final burn of the engines at 19:27 UTC to refine the approach, and by 21:00 UTC, the shuttle was in position below the station to allow the station crew to photograph the underside of the orbiter. Ferguson guided the shuttle manually through the Rendezvous pitch maneuver

 (RPM) while station crew used 400mm and 800mm cameras to take high-resolution images of the thermal tiles on Endeavour. The images were downlinked to NASA's image analysis team to assist in the evaluation of the thermal protection system of the orbiter. After the RPM was complete, Ferguson guided the orbiter into a safe docking at 22:01 UTC (17:01 EST), and the hatches were opened at 00:16 UTC (19:16 EST). Upon entering the station, Ferguson joked "Hey, we figured we'd go for a 10-year anniversary party for the space station, so that's what we showed up for." Ferguson was referring to the 20 November 1998 launch of Zarya

, the first component of the International Space Station.

After the two crews exchanged greetings, they performed a safety briefing, and then set right to work, beginning transfers and preparing for robotic operations. At 02:50 UTC, Chamitoff and Magnus officially switched positions, with the swap of their Soyuz seatliners. Chamitoff joined the STS-126 crew as a Mission Specialist, and Magnus officially became the Flight Engineer 2 for Expedition 18.

During the mission status briefing, LeRoy Cain stated that the image analysis team was still evaluating the ascent imagery, but that the vehicle looked very clean, and the only event that was seen on launch, the area under the left OMS pod, appeared to have been ice. The images taken during the flight day two survey showed that all of the thermal blankets in that area were intact, as were the tiles. Cain stated that the item did not strike the orbiter, it was the only event that the Mission Management Team was still evaluating, and that the orbiter was in good shape. Mike Sarafin confirmed that the Ku band antenna performed properly in radar mode, and docking was carried out without any problems with the antenna.

17 November (Flight day 4)

Following the wake up call, the two crews began the procedures to move the Leonardo MPLM out of the orbiter's payload bay to install it on the Earth-facing port of the Harmony module. Using the station's robotic arm, Pettit and Kimbrough began maneuvering the 27,000 lb

 container around 16:45 UTC, and by at 18:04 UTC it was locked in place. After performing leak checks, the hatch was opened at 23:43 UTC. The crews took air samples and examined the container for any signs of condensation or shifting of the contents during launch. The container had no issues, and transfer of cargo between the container and the station began shortly after the hatch was opened. The team also worked on experiments that were flown with Endeavour, including one that involves observing spiders and butterflies in space. The experiment from Florida, Texas and Colorado

) to lessen the time needed to acclimate to the environment in the spacesuits.

During the Mission Management Team briefing, LeRoy Cain confirmed that the orbiter's wing leading edge had been cleared, and that no focused inspection would be required. The time that was scheduled for that inspection on day six would instead be spent working on the station's new water reclamation unit. While the image analysis team was still reviewing the imagery from the day two inspection and RPM, Cain said the orbiter was "doing extremely well", and expected the image analysis team to clear it for re-entry within a day. Cain noted that the imagery from the external tank showed it to be extremely clean, with only three small areas of foam loss noted.

During the Mission Status briefing, ISS Deputy Program Manager Kirk Shireman noted the upcoming ten-year anniversary of the International Space Station. Shireman reviewed the progress and advancements that have come from the project, and reviewed some of the major milestones. Thirty Progress

18 November (Flight day 5)

Following their post-sleep period, the crews set to work preparing for the first spacewalk of the mission. Stefanyshyn-Piper and Bowen were suited up and in the airlock ahead of schedule, and the EVA started at 18:09 UTC, with Piper becoming the first female Lead Spacewalker. While Piper was preparing to begin work on the SARJ, she noticed a significant amount of grease in her tool bag, "I think we had a grease gun explode in the large bag, because there's grease in the bag," Piper reported to Kimbrough, who was working inside the shuttle to help coordinate the EVA. Mission Control managers instructed Piper to clean up the grease using a dry wipe, and while she was doing the cleanup, one of the crew lock bags floated away. "I guess one of my crew lock bags was not transferred and it's loose," Piper told Kimbrough. The bag floated aft and starboard of the station, and did not pose a risk to the station or orbiter. After taking an inventory of the items inside the lost bag, managers on the ground determined that Bowen had all those items in his bag, and the two could share equipment. While it extended the EVA duration slightly, the major objectives were not changed, and all EVA tasks were accomplished. The estimated value of the lost tool bag was $100,000 US$. An amateur astronomer later observed the tool bag as it orbited the Earth prior to re-entering. It was not the first time that equipment had got away from spacewalkers, items lost in the past include tools, nuts and bolts, glue guns, cameras, cloths, and even a robotic arm.

During the Mission Status Briefing, lead ISS Flight Director Ginger Kerrick noted that there was no way to know what caused the bag to come loose. "We don't know that this incident occurred because they forgot to tether something. We don't know if perhaps the hook just came loose inside the bag," Kerrick said. "You've got to remember, we are working with humans here and we are prone to human error. We do the best we can, and we learn from our mistakes." Kerrick noted that the team would be taking extra precautions to avoid any further problems with the grease guns, by attaching them to the outside of the bags instead of inside to prevent the plungers from being inadvertently activated.

19 November (Flight day 6)

Flight day six was devoted to transfer operations, and the two crews worked through the morning to complete all the rack transfers. Magnus and Chamitoff successfully installed the two crew quarters racks into the Harmony node, and installed a rack with equipment to be returned to Earth into the MPLM. During the Mission Status briefing, Lead ISS Flight Director Ginger Kerrick noted that all the racks were now on station, and about 25% of the cargo transfers had been completed, which was slightly ahead of schedule. The two crews also began working on activating the Water Recovery System, so that samples of water from two areas could be taken and returned to Earth with Endeavour. The system's initial checkout was initiated, and water samples would be taken after several days of operation. Later in the day, the two crews reviewed procedures for the mission's second EVA, and Stefanyshyn-Piper and Kimbrough would sleep in the station's airlock as part of the pre-EVA campout procedure.

20 November (Flight day 7)

On the tenth anniversary of the International Space Station, Stefanyshyn-Piper and Kimbrough successfully conducted the mission's second spacewalk. The EVA was 6 hours and 45 minutes in duration, and all tasks were accomplished without complications. Two crew equipment carts were relocated in preparation for the arrival of the final set of solar arrays, the station's robotic arm was lubricated, and the work on the starboard SARJ continued. Inside the station, crewmembers continued to transfer cargo from Leonardo to the station, items to be returned to Earth into the MPLM, and continued the activation of the Water Recovery System.

21 November (Flight day 8)

Following the crew wake up call, the two crews set to work on the day's planned activities. Fincke and Magnus tested latches on the Exposed Facility Berthing Mechanism for the Japanese Kibo laboratory. Magnus 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. Engineers were considering if the issue was a problem with the sensors, or with the centrifuge motor. At 17:10, Ferguson and Boe used the shuttle's engines to reboost the station's altitude, raising it by about one nautical mile

 arrival.

The two crews also participated in the traditional Joint Crew News Conference, answering questions from reporters around the world, and took the traditional crew photo. Cargo transfers continued between the vehicles, and the crew was about seventy-five percent complete with all transfers to and from the MPLM. After a bit of off-duty time, the two crews participated in an EVA review, in preparation for the mission's third spacewalk. Piper and Bowen spent the night in the Quest airlock for the campout prior to the next day's spacewalk.

22 November (Flight day 9)

After awakening, the two crews set right to work preparing for the mission's third EVA, which began at 18:01 UTC. The entire spacewalk was devoted to completing the cleaning, lubrication, removal and replacement of the trundle bearings assemblies in the starboard SARJ. The final trundle bearing assembly installation was deferred to the fourth EVA, but all other tasks scheduled were accomplished without any issues. Stefanyshyn-Piper's fifth EVA moved her to the twenty-fifth spot in cumulative EVA time with thirty three hours, forty two minutes.

On the station, the crews continued to work on transfer operations, and continued work on the water reclamation system. During the Mission Status Briefing, lead ISS Flight Director Ginger Kerrick noted that a sample was taken from the Water Processor Assembly that contained 10% urine and 90% condensate, and would be returned to the ground with the shuttle. Kerrick noted that if activation of the system continued on schedule, a sample from the potable water dispenser would be taken on flight day eleven. The ground crew continued to troubleshoot the Urine Processor Assembly, looking at whether there is a sensor touching part of the system’s centrifuge as it rotates, which might be causing it to slow down.

23 November (Flight day 10)

The two crews continued transfer operations, and Finke and Pettit 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 has continued to operate sporadically, shutting itself down after two to three hours of operations, and the engineers on the ground are still evaluating the possible causes and solutions. Managers on the ground would make a decision Monday on whether to extend Endeavours mission by one docked day, to help with the troubleshooting of the Water Recovery System (WRS). The Endeavour crew had several hours of off-duty time, and participated in media interviews.

24 November (Flight day 11)

Following the wake up call, the two crews got to work preparing for the mission's final spacewalk. Bowen and Kimbrough officially began the EVA at 18:24 UTC. Shortly before the spacewalk began, managers on the ground radioed up to the crew that the Mission Management Team had approved an extra docked day of operations for the crews, extending the mission to sixteen days. The extra time was being given to allow the crews more time to resolve the issues with the Urine Processing Assembly. The spacewalk successfully concluded after 6 hours and 7 minutes, bringing the total time spent in EVA activities for the mission to 26 hours, 41 minutes.

25 November (Flight day 12)

The crews dedicated most of the day to completing the transfer of supplies from the space station to Endeavour and Leonardo. The starboard Solar Alpha Rotary Joint was automatically tracking the sun for the first time in more than a year during a three-hour, two-orbit test that was initiated at 10:55 UTC. The Urine Processor Assembly completed its second full five hour run.

During the Mission Status Briefing, International Space Station Program Manager Mike Suffredini noted that the water recycling system appeared to be functioning normally after the modifications performed by the crew on orbit. Additional water samples were taken, and the crew would be bringing home approximately six liters of sample water for extensive testing. The crew on the station would not be drinking any of the water until the engineers and scientists on the ground had a chance to thoroughly analyze the samples taken. Suffredini also noted that while the goal of the EVA activities to perform maintenance on the starboard SARJ was to allow it to operate "periodically", the initial test showed encouraging results, and the lubrication and other work done by the spacewalkers may allow for more routine operations than originally expected. It would be weeks before a more complete assessment could be given, the joint would need to be put through more testing, as well as analysis of the results from engineers on the ground, but Suffredini was encouraged by the initial results.

26 November (Flight day 13)

Pettit and Kimbrough used the station’s Canadarm2 to move Leonardo from the Harmony module and placed in the shuttle’s cargo bay at 21:52 UTC. Stefanyshyn-Piper packed up equipment and supplies used for the four spacewalks and moved them to Endeavour for return, while Magnus 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.

27 November (Flight day 14)

In their final day of joint operations, the two crews had some off-duty time, spoke to reporters, and shared a Thanksgiving Day meal together. Following the meal, the crews worked on last minute transfers, and gathered in the Harmony node to bid farewell. The hatches between the two vehicles were closed 23:31 UTC, with the crew of Endeavour reviewing the procedures and tools they would use the next day for undocking, scheduled for 14:47 UTC.

28 November (Flight day 15)

Endeavour undocked from the International Space Station at 14:47 UTC. The total docked time was 11 days, 16 hours, and 46 minutes, making it the second-longest docked shuttle mission to the station, after STS-123

's 11 days, 20 hours and 36 minutes. Pilot Eric Boe maneuvered the shuttle through a flyaround inspection of the complex, but the final separation burn was delayed to avoid bringing the shuttle near the remains of a Russian Cosmos satellite that broke apart in March. While the burn would have only brought them about eleven kilometers from the debris, Flight Director Mike Sarafin noted during the Mission Status Briefing that "Per the flight rules, it was the safe course of action to not perform that burn." The burn was instead completed at 23:23 UTC. After separating from the station, the crew of Endeavour conducted an inspection of the shuttle's heat shield with the robotic arm.

29 November (Flight day 16)

Following the late inspection of Endeavours heat shield, the Mission Management Team officially cleared the orbiter for re-entry. The crew spent the day preparing for landing, performing inspections and checkout of the shuttle's flight control surfaces and reaction control system thrusters.

 for the first day of landing opportunities. There were two KSC opportunities, with two more opportunities for Edwards later in the day. If the first two opportunities at KSC were called off due to weather, Bryan Lunney, Entry Flight Director stated during the Mission Status Briefing that they would take the Edwards opportunities; the weather was not likely to improve, so there would be no reason to delay landing for a day. The forecast at KSC called for thunderstorms within 30 miles of the landing site, as well as high crosswinds, both conditions that would violate the weather constraints for landing.

30 November (Flight day 17)

After awakening, the crew of Endeavour got to work preparing for reentry. While working through the deorbit timeline, Entry Flight Director Bryan Lunney, after reviewing the weather, waved off the first KSC landing opportunity due to excessive crosswinds on the runway. After evaluating the weather, the second KSC landing opportunity was also waived off, as the weather was "no go" and forecasted "no go" per the landing weather requirements. Lunney continued to watch the weather for possible changes in Monday's weather forecast prior to making the decision whether to land at Edwards, or wait one day to get a Kennedy landing, but following further analysis of the projected weather in Florida for Monday, Lunney decided to take the first Edwards Air Force Base landing opportunity. The deorbit burn was initiated at 20:19 UTC (12:19 PST), and the orbiter landed at Edwards Air Force Base at 21:25 UTC (13:25 PST).

Endeavour was the first and last orbiter to land on the temporary runway 04 at Edwards AFB, as the main runway was completing refurbishment. The use of the temporary runway required new braking and rollout techniques that have never been used before, as the runway is three thousand feet shorter than the normal runway.
