Discovery's crew is still working on the retraction of the port P6 solar arrays that began at 1:28 p.m. EST (6:28 utc). The bays have not been folding properly, and astronauts have been repeatedly retracting and deploying the panels in an attempt to properly align them.

The folding of this 115-foot long solar array, which has been unfurled for more than 6 years, will permit the activation of a rotary joint on the P4 truss. The Solar Alpha Rotary Joint, or SARJ, enables the solar arrays on the P4 to follow the sun as the station moves through orbital sunrise and sunset.

Activation of the SARJ will follow the retraction.

Two more spacewalks during STS-116's stay will rewire and redistribute power on the station.

Once automatic sun tracking is confirmed for the new P4 arrays, the stage is set for the second spacewalk, scheduled to begin at 3:12 p.m.(8:12 UTC) Thursday. Mission Specialists Bob Curbeam and Christer Fuglesang, who conducted the mission’s first spacewalk, will perform Thursday’s excursion.

Curbeam and Fuglesang will again "campout" in the station’s airlock to prepare for the spacewalk. During the overnight “campout” the pressure will be lowered in the airlock to the pressure normally found on Earth 10,000 feet above sea level. The procedure protects against decompression sickness as Curbeam and Fuglesang go to the even lower pressure of spacesuits on Thursday.

In other activities today, crewmembers will field questions from the CBS Radio Network, the Fox Radio Network and SPACE.com at 8:07 p.m.
