Space shuttle Discovery is silhouetted against the dawn's early light as it makes the slow 3.4-mile journey to Launch Pad 39A. The shuttle sits atop the mobile launcher platform, which are being moved by the massive crawler-transporter beneath. First motion out of the Vehicle Assembly Building was at 5:17 a.m. EST. 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.
