Space shuttle Discovery, atop the mobile launcher platform, reaches the top of Launch Pad 39A at NASA's Kennedy Space Center in Florida. At left is the White Room, attached to the end of the orbiter access arm. Behind the shuttle can be seen the Atlantic Ocean. Discovery's first motion out of the Vehicle Assembly Building was at 5:17 a.m. EST. Discovery was secured to the pad at 12:16 p.m. Discovery is targeted to launch to the International Space Station Feb. 12. During Discovery's 14-day mission, the crew will install the S6 truss segment and its solar arrays to the starboard side of the station, completing the station's backbone, or truss, enabling a six-person crew to live there starting in May.
