Today's wakeup music was "Ain't Nobody Here but Us Chickens" by Louis Jordan played for Discovery astronaut Steve Swanson at 6:43 a.m. EDT, suggested by his children.

Astronauts aboard Discovery begin the mission's third spacewalk at 11:43 a.m. During the 6.5 hour excursion, Joseph Acaba and Richard Arnold will relocate a cart that moves along the rails of the station's truss, attempt again to deploy the unpressurized cargo carrier attachment system, install a similar attachment system on the starboard side, lubricate the space station arm's end effector and reconfigure some cables that power the station's gyroscopes.
