Atlantis' crew awoke at 09:28 UTC.
Just after 12;00 UTC, Atlantis Commander Charles Hobaugh and Mission Specialist Leland Melvin used the shuttle robotic arm to grasp the Express Logistics Carrier (ELC2), located in Atlantis' payload bay.

Internal shuttle-to-station transfer of material kept the crew members busy through flight day 5.
As a result, well over half the mission's transfer activities were completed.
Inside the station's Unity node, crew members also completed the two-day task of outfitting the node.
They routed a slew of cables, hoses and fluid lines to prepare for the arrival of the Tranquility node aboard STS-130, the next scheduled shuttle mission.

Over the course of day, several of the crew participated in chats with media representatives on the ground to answer their questions related to the mission and the experience of being up in space.
Shortly after 11:00 UTC, Commander Hobaugh and Pilot Wilmore talked with CBS News, FOXNews Radio and Nashville's WTVG-TV.
At 12:28 UTC, Melvin and Satcher were interviewed by the Tom Joyner Morning Show and at 21:33 UTC, Hobaugh, Melvin and Satcher talked with ESPN's SportCenter, Black Entertainment Television News and WRIC-TV in Richmond, Virginia.

The crew also got prepared for the mission's second spacewalk on Saturday.
These tasks included recharging batteries, switching out Robert Satcher's spacesuit for that of Randolph Bresnik and reviewing procedures.

The crew went to their sleep period at 00:28 UTC, a half-hour later than the station crew.
Astronauts Foreman and Bresnik were to spend the night in the Quest airlock as part of the overnight "campout" procedure.
Again, for the second night in a row, fire and depressurization alarms tripped inside the European Columbus Module and the Quest airlock woke the Atlantis astronauts.
The depressurization alarm triggered automatic procedures that brought the airlock back up to the station's normal pressure of 14.7 psi.
Because of time needed to reset various systems, Foreman and Bresnik were informed to forgo the normal "campout" procedure and to sleep wherever they liked, at the station's normal pressure.
The flight controllers suspected that the alarms are a result of an unresolved problem with a newly arrived Russian Poisk (MRM2) module.
