Discovery's crew was awakened at 10:39 p.m. CDT by the song "Vertigo" by U2 played for Pilot Jim Kelly. Capcom Shannon Lucid noted during the wakeup call that Kelly, whose nickname is "Vegas," was promoted to Colonel in the U.S. Air Force recently. The Station crew was awakened at 11:09 p.m. CDT by a tone onboard.
In this upcoming flight day, Mission Specialist Wendy Lawrence and Kelly will guide the Station's robot arm, Canadarm2, to pluck the Multi Purpose Logistics Module from Discovery's cargo bay and install it on the Station. The MPLM, called Raffaello, will be attached to the Station's Unity module. While the crew was asleep, the Station flight control team verified Unity's attach mechanism is ready for the addition.
Kelly and Station Flight Engineer John Phillips will walk Canadarm2 off of the Destiny lab beginning at 4:39 a.m. CDT., onto the Mobile Base System for situational awareness views from its cameras for the survey. Mission Specialist Charlie Camarda and Kelly will begin additional focused inspections of Discovery's heat shield using the Shuttle arm and Orbiter Boom Sensor System shortly after 6 a.m. Central time.
Once the MPLM is in place, Mission Specialist Wendy Lawrence and Station Commander Sergei Krikalev will begin activation of the module about 7:49 a.m. CDT and will enter about two hours later, at 9:49 a.m. CDT.
Commander Eileen Collins and Mission Specialist Andy Thomas will participate in interviews with the Associated Press Radio Network, National Public Radio and the CBS Radio Network at 5:19 a.m. CDT.
Additional preparations for Saturday's first spacewalk of the mission by Soichi Noguchi and Steve Robinson will continue during the day with a review of EVA procedures and a checkout of a small rescue device known as SAFER, for Simplified Aid For EVA Rescue, designed to allow an astronaut outside a spacecraft to return safety if they become untethered and separated from the spacecraft. Hatches between Discovery and Station will be closed as the Shuttle's cabin pressure is reduced to 10.2 psi for the pre-breathe period, during which spacewalkers will become gradually acclimated to the lower pressures of spacesuits.
The crews of Discovery and the Station are scheduled to go to sleep about 2:39 p.m. CDT.
