Thirty minutes later than planned, Mission Control Center, Houston sent the crew wake-up call at 08:58 UTC.

The major activity for the day was mission's second spacewalk (EVA 2) by astronauts Foreman and Bresnik.
Because of last night's space station false alarms sounded at 02:53 UTC, spacewalk was shortened to six hours and delayed the start.
Mission Specialist Satcher, serving as the intravehicular crew member helped to direct the spacewalk.
The spacewalking pair finished all their assigned work way ahead of timeline with no major problems and completed several "get ahead" tasks originally scheduled for the mission's third spacewalk.
EVA 2 marked: 229th spacewalk conducted by U.S. astronauts, the 135th in support of space station assembly and maintenance, 107th spacewalk out of the space station, the fifth for Foreman and the first for Bresnik.
Also between STS-123 and STS-129, Michael Foreman has completed five spacewalks totaling 32 hours, 19 minutes and placing him 28th on the all-time list.

Earlier, at 11:32 UTC, Atlantis robotic arm operators Leland Melvin and Robert Satcher lifted ExPRESS Logistics Carrier 2 out of the shuttle payload bay and handed off to space station's robotic arm, Canadarm2.
Just before the beginning of Saturday's spacewalk, at 14:14 UTC Mission Specialists Leland Melvin and Nicole Stott operating Canadarm2 mated the Carrier to the Outboard Payload Attachment System (PAS) on the S3 segment of the space station's main truss.

Ground engineers declared that a minor ring misalignment on Atlantis' Orbiter Docking System (ODS) is of no issue.
They cleared the system for undocking and redocking with the space station—a safe haven scenario which would only be initiated in the event Atlantis has to return to the ISS.
The docking ring had lost alignment during ring extension on flight day 2.
