Rolling to the Start
Space shuttle Discovery rolled out of Orbiter Processing Facility 3 at NASA's Kennedy Space Center on its way to the Vehicle Assembly Building (in the background). In the VAB, Discovery will be attached to its external fuel tank and twin solid rocket boosters. After additional preparations are made, the shuttle will be rolled out to Launch Pad 39A for a targeted launch to the International Space Station on Feb. 12, 2009.
