STS-126 launch Nov. 14, 2008

STS-126 was scheduled to be a sixteen-day mission with four spacewalks, largely dedicated to servicing and repair of the Solar Alpha Rotary Joints (SARJ).[3][17] An additional docked day was added to the flight plan to give the crew more time to complete their tasks. The starboard SARJ had shown anomalous behavior since August 2007, and its use has been minimized pending diagnosis and repair.[19][20][21] Both the starboard and port SARJs were serviced. In addition to lubricating both bearings, the remaining 11 trundle bearings in the starboard SARJ were replaced. Trundle bearing assembly five was removed during an Expedition 16 EVA for further examination in December 2007.
STS-126 included the Leonardo Multi-Purpose Logistics Module (MPLM) on its fifth spaceflight.
