At NASA's Kennedy Space Center in Florida, shuttle Discovery is ushered into the Vehicle Assembly Building (VAB) from Orbiter Processing Facility-3 during a move known as "rollover." The large, yellow and metal sling to the left of Discovery will hoist the spacecraft out of the VAB transfer aisle and then lower it to its external fuel tank and twin solid rocket boosters. Later this month, Discovery is scheduled to "rollout" to Launch Pad 39A for its launch to the International Space Station on the STS-133 mission.
Targeted to liftoff Nov. 1, Discovery will take the Permanent Multipurpose Module (PMM) packed with supplies and critical spare parts, as well as Robonaut 2 (R2) to the station. Photo credit: NASA/ Dimitri Gerondidakis
