STS-126 Report #16 9 a m CST Saturday, Nov 22, 2008 Mission Control Center, Houston, Texas

HOUSTON – The third spacewalk by Endeavour astronauts outside the International Space Station will be the focus of today’s activities aboard the two spacecraft

Endeavour crew members Commander Chris Ferguson, Pilot Eric Boe and mission specialists Don Pettit, Steve Bowen, Heidemarie Stefanyshyn-Piper, Shane Kimbrough and Greg Chamitoff were awakened at 7:55 a m CST The song was “You Are Here,” by the group Dutton It was played for Kimbrough

Spacewalkers Piper and Bowen are scheduled to leave the station’s Quest airlock at 12:45 p m Piper, the lead spacewalker, will wear the red-striped suit while Bowen will be in the all-white suit Their work will be further cleaning and lubrication of the starboard Solar Alpha Rotary Joint (SARJ) and replacement of some of more its bearing assemblies

The joint has seen limited use since September 2007 when flight controllers saw increased power consumption and vibration as it moved the 240-foot solar wings like a paddlewheel to follow the sun Much of the work on all four spacewalks during Endeavour’s stay at the station involves the starboard SARJ The port SARJ, which continues to function well, will get a precautionary lubrication on the Monday spacewalk

Kimbrough, who participated in the Thursday spacewalk, will be today's intravehicular officer, or spacewalk choreographer The spacewalk is planned for about seven hours

Just about every day Endeavour is at the station is moving day Crew members of both spacecraft, including Expedition 18 commander Mike Fincke and flight engineers Yury Lonchakov and Sandy Magnus, will continue moving supplies and equipment between Endeavour and the International Space Station and work on station equipment

Work continues to check out the Water Recovery System and its Urine Processor Assembly The UPA was activated again overnight to gather more information on why it had shut down on previous tests One theory is that its centrifuge might as it rotates be touching another structure

Endeavour’s crew is scheduled to go to bed at 11:55 p m today and be awakened at 7:55 a m Sunday The next shuttle status report will be issued at the end of the crew day, or earlier if events warrant

STS-126 Report #17 Saturday, November 22, 2008 - 10:00 p m CST Mission Control Center, Houston, Texas

HOUSTON – Astronauts Heidemarie Stefanyshyn-Piper and Steve Bowen today completed the third spacewalk of Endeavour’s mission to the International Space Station The spacewalk began at 12:01 p m CST and ended at 6:58 p m for a total time of six hours and 57 minutes

Piper and Bowen focused their efforts on the continued cleaning of the station’s starboard solar alpha rotary joint (SARJ) and the removal and replacement of the remaining trundle bearing assemblies (TBA) Today, Piper replaced three TBAs and Bowen replaced two Five have been replaced during the mission’s prior two spacewalks, and one was replaced on the STS-124 mission this past summer The two astronauts also cleaned the area around the SARJ’s drive lock assemblies, which help the joint to rotate and lock into place

A final trundle bearing assembly replacement will take place during the fourth and final spacewalk of the flight, which is scheduled for Monday That spacewalk, which will be conducted by Shane Kimbrough and Bowen, will focus on the lubrication and servicing of the port SARJ

Work continued inside the station on the transfer of cargo and supplies from the Leonardo Multipurpose Logistics Module (MPLM) The station and shuttle crews also worked on setting up the station’s new Water Recovery System (WRS), with Expedition 18 Flight Engineer Sandy Magnus working on taking the first samples from the Water Processor Assembly (WPA) Ground controllers in Houston continue to examine data from the Urine Processor Assembly, which is also part of the WRS, to determine why it continues to experience errors Engineers are exploring the possibility that there is a sensor touching part of the system’s centrifuge as it rotates, which might be causing it to slow down

Endeavour’s crew is scheduled to go to bed at 11:55 p m tonight and be awakened at 7:55 a m Sunday The next shuttle status report will be issued at the beginning of the crew day, or earlier if events warrant
