Space shuttle Atlantis stands ready in the Vehicle Assembly Building at NASA’s Kennedy Space Center for the pending rollout to Launch Pad 39A. Visible at right behind Atlantis is the external fuel tank. The Sept. 2 rollout date was postponed due to Tropical Storm Hanna’s shift to a northern track. Managers are closely following Hanna to determine when would be the best time this week to move space shuttle Atlantis to its launch pad. The tentative rollout time is 10 a.m. Sept. 4, depending on the track Hanna follows along the Florida coast. 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/Jack Pfaller
