Another spacewalk is the order of business aboard Atlantis and the International Space Station today to complete the installation and checkout of the newly installed truss segment.
Dave Wolf and Piers Sellers once again will conduct the spacewalk out of the Quest Airlock beginning about 9:40 this morning. It is the 46th spacewalk devoted to the assembly and maintenance of the station. Today they will focus on the removal and stowage of launch support brackets no longer required; installation of additional clamps on fittings to prevent pressure buildup in fluid lines; install an attach bracket for a future station truss element; and remove a balky bolt preventing activation of a cable cutter on the Mobile Transporter.
Ahead of the spacewalk, Atlantis' thrusters will again be used to gently raise the station's altitude another couple of miles. The reboost lasts about 35 minutes and sets the stage for the arrival of a Russian Soyuz spacecraft set to launch from the Baikonur Cosmodrome in Kazakhstan on Oct. 28. The Soyuz serves as the emergency rescue vehicle of the station and must be replaced about every six months.
Shortly after crew wakeup today, one of the three cooling radiators on the newly installed S1 Truss was deployed serving as a mechanical test for the deployment system. The deployment to its full length of 75 feet began at 3:01 a.m. and was completed nine minutes later. The task was delayed from Sunday for an electrical adjustment. The radiator is not needed operationally until next year.
Peggy Whitson, NASA ISS science officer, and Atlantis' Sandy Magnus will operate the station's robot arm throughout the spacewalk, while Pilot Pam Melroy will again choreograph the Extravehicular Activity (EVA) from Atlantis' flight deck. Wolf will wear the spacesuit with red stripes and Sellers' suit will be all white.
Today's wakeup music for Dave Wolf from his wife Tammy was "You Gave Me The Answer," by Paul McCartney and Wings and came at 2:46 a.m. The station crewmembers awakened about 30 minutes later.
The next STS-112 mission status report will be issued later today.
