A crawler transporter moves Space Shuttle Discovery, secured atop a mobile launch platform, along the crawlerway from the Vehicle Assembly Building to Launch Pad 39A at NASA's Kennedy Space Center, Florida, September 30, 2007. The transfer to Kennedy Space Center's massive assembly building had been delayed several days for last-minute repairs to the spaceship's landing gear. Technicians discovered a leaky seal, which had to be replaced. Discovery and its seven astronaut crew are targeted to launch October 23 on the STS-120 mission to the International Space Station.
