Space station commander Peggy Whitson and Yuri Malenchenko, midway through a planned six-and-a-half-hour spacewalk, have completed work to prepare the lab's shuttle docking port for a move Monday from the front of the station to the new Harmony module.
With Dan Tani providing guidance from inside the space station, Whitson and Malenchenko disconnected cables that feed solar array power to docked space shuttles, removed a floodlight and unplugged and tied off electrical cables between the docking port and the Destiny lab module. If all goes well, Tani, operating the station's robot arm, will detach pressurized mating adapter No. 2 Monday so it can be bolted to the newly arrived Harmony. Two days later, the Harmony/PMA-2 stack will be moved to the front of Destiny and bolted in place.
Whitson currently is wrapping up work to connect electrical cables to a robot arm mounting fixture on Harmony while Malenchenko replaces a faulty circuit breaker. Other tasks remaining are removal of a protective cover over the Harmony port where PMA-2 will be attached; electrical cable reconfigurations and retrieval of a communications system component that will be returned to Earth later.
The spacewalk has proceeded smoothly, with no problems of any significance other than a few balky connectors that took a bit more force than expected to unplug. Pausing at one point, Whitson marveled: "I can't help but notice every once in a while this incredible view we've got going on out here."
