Following the crew's post-sleep activities, the two crews set to work preparing for the next day's spacewalk, by moving the S6 truss out of Discovery's payload bay.
Due to clearance restrictions, the station's robotic arm was not able to perform the move by itself, so a series of 'handoffs' were performed to prepare the truss for installation.
Phillips and Magnus controlled the station's arm, grappled the truss and moved it into a position where the shuttle's robotic arm, operated by Antonelli, could take possession.

The station arm was then moved along the mobile base to a work site on the far right side, closer to the installation point.
The shuttle's robotic arm then handed the truss back to the station's arm, where it remained overnight.

The crews took part in a media event with Channel One News, and performed a review of the procedures for the first EVA.
Mission Specialists Swanson and Arnold spent the night in the Quest airlock camping out in a reduced-nitrogen atmosphere, a standard procedure designed for spacewalkers to prevent decompression symptoms.

During the Mission Management Team briefing, Lead ISS Flight Director Kwatsi Alibaruho noted that the imagery specialists with the Damage Assessment Team had completed the initial review of the launch and flight day 2 photography, and a focused inspection of the orbiter would not be required.
