Water trucks spray the crawlerway at NASA's Kennedy Space Center in Florida to reduce dust as space shuttle Discovery, atop the mobile launcher platform and crawler-transporter, makes the slow journey onto Launch Pad 39A. 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.
