Space Space shuttle Atlantis curves toward Launch Pad 39A (at left) on the crawlerway at NASA's Kennedy Space Center after rolling from the Vehicle Assembly Building. The shuttle stack, with solid rocket boosters and external fuel tank attached to Atlantis, rest on the mobile launcher platform. Movement is provided by the crawler-transporter underneath. First motion occurred at 9:19 a.m. EDT. The Sept. 2 rollout date was postponed due to Tropical Storm Hanna’s shift to a northern track. Atlantis is scheduled to launch on the STS-125 mission to service NASA’s Hubble Space Telescope. Launch is targeted for Oct. 8. Photo credit: NASA/Kim Shiflett
