Atlantis docks to space station to begin repair effort

Approaching the unfinished station from directly above, Halsell manually piloted Atlantis, its payload bay facing Earth, to a linkup at 12:31 a.m. EDT (0431 GMT) to close out a two-day orbital chase.
"Houston, we have capture," radioed Halsell as the docking mechanism engaged.
"Roger, congratulations," replied astronaut Chris Hadfield from mission control in Houston.
After a short pause to allow any relative motion to damp out, the shuttle's extended docking mechanism slowly retracted, firmly locking the two craft together. A few minutes later, Houston gave Halsell and company permission to take over attitude control of the combined vehicles, using the shuttle's maneuvering thrusters to keep both craft properly oriented in space.
"It's hard to make it look any easier than the crew made it look today," flight director Phil Engelauf told reporters later. "This was really a textbook rendezvous, everything went virtually exactly per the timeline, per the procedures."
The trouble-free docking capped a near-perfect rendezvous that began with Atlantis's liftoff Friday from the Kennedy Space Center. The only departure from NASA's usual script was the use of just one of the shuttle's two orbital maneuvering system - OMS - engines for rendezvous rocket firings that typically would have been carried out with both. Questions about the status of a valve in the left-side OMS pod, however, prompted flight planners Friday to rule out any more firings by the left engine until the end of the mission.
With docking behind them, the astronauts turned their attention to a spacewalk late this evening by astronauts James Voss and Jeffrey Williams to install a Russian cargo boom on the station's hull and to replace a faulty antenna on the Unity node module.
The 6 1/2-hour excursion is scheduled to begin at 10:31 p.m. EDT tonight (0231 GMT Monday). The astronauts will not open hatches between the shuttle and the space station until Monday evening, finally floating inside around 8:11 p.m. EDT.
