KENNEDY SPACE CENTER, FLA. -- After leaving the Orbiter Processing Facility bay 2, the orbiter Endeavour, atop its transporter, rolls toward the Vehicle Assembly Building. In the VAB, it will be stacked with the external tank and solid rocket boosters atop the mobile launcher platform for its launch on mission STS-118. The mission will be Endeavour's first flight in more than four years. The shuttle has undergone extensive modifications, including the addition of safety upgrades already added to shuttles Discovery and Atlantis. Endeavour also features new hardware, such as the Station-to-Shuttle Power Transfer System that will allow the docked shuttle to draw electrical power from the station and extend its visits to the orbiting lab. Endeavour is targeted for launch on Aug. 7. Photo credit: NASA/Kim Shiflett KSC-07pd1709

KENNEDY SPACE CENTER, FLA. - As afternoon storm clouds sweep across a dune near Launch Pad 39A, Space Shuttle Endeavour is seen from the back side. In front of it is the 290-foot-tall water tower that provides the deluge over the mobile launcher platform for sound suppression during liftoff. The shuttle arrived at the pad in the early morning after an 8:30 p.m. rollout on July 10. Endeavour is scheduled to launch on mission STS-118 on Aug. 7. During the mission, Endeavour will carry into orbit the S5 truss, SPACEHAB module and external stowage platform 3. The mission is the 22nd flight to the International Space Station and will mark the first flight of Mission Specialist Barbara Morgan, the teacher-turned-astronaut whose association with NASA began more than 20 years ago. STS-118 will be the first flight since 2002 for Endeavour, which has undergone extensive modifications, including the addition of safety upgrades already added to orbiters Discovery and Atlantis.

KENNEDY SPACE CENTER, FLA. -- Space Shuttle Endeavour, atop the mobile launcher platform, is hard down on Launch Pad 39A after rolling out overnight. First motion out of the Vehicle Assembly Building was at 8:10 p.m. July 10. The components of the shuttle are, first, the orbiter and then the solid rocket boosters flanking the external tank behind it. To the left of the shuttle is the rotating service structure, which can be rolled around to enclose the vehicle for access during processing. Behind it is the fixed service structure, topped by an 80-foot-tall lightning mast. Extending from it to Endeavour is the orbiter access arm, which provides access into the vehicle. Endeavour is scheduled to launch on mission STS-118 on Aug. 7. During the mission, Endeavour will carry into orbit the S5 truss, SPACEHAB module and external stowage platform 3. The mission is the 22nd flight to the International Space Station and will mark the first flight of Mission Specialist Barbara Morgan, the teacher-turned-astronaut whose association with NASA began more than 20 years ago.

KENNEDY SPACE CENTER, FLA. -- Near sunset, Space Shuttle Endeavour, atop the mobile launcher platform, begins moving through the doors of the Vehicle Assembly Building for rollout to Launch Pad 39A. First motion out of the VAB was at 8:10 p.m. July 10, and the shuttle was hard down on the pad at 3:02 a.m. July 11. Seen below the orbiter's wings and attached to the launcher platform are the tail masts, which provide several umbilical connections to the orbiter, including a liquid-oxygen line through one and a liquid-hydrogen line through another. Endeavour is scheduled to launch on mission STS-118 on Aug. 7. During the mission, Endeavour will carry into orbit the S5 truss, SPACEHAB module and external stowage platform 3.

KENNEDY SPACE CENTER, FLA. -- At sunset, Space Shuttle Endeavour, atop the lighted mobile launcher platform, exits the Vehicle Assembly Building for rollout to Launch Pad 39A. First motion out of the VAB was at 8:10 p.m. July 10, and the shuttle was hard down on the pad at 3:02 a.m. July 11. Seen below the orbiter's wings and attached to the launcher platform are the tail masts, which provide several umbilical connections to the orbiter, including a liquid-oxygen line through one and a liquid-hydrogen line through another. The shuttle and platform are being carried by the crawler-transporter. The trip will take between six and eight hours. Endeavour is scheduled to launch on mission STS-118 on Aug. 7. During the mission, Endeavour will carry into orbit the S5 truss, SPACEHAB module and external stowage platform 3. The mission is the 22nd flight to the International Space Station and will mark the first flight of Mission Specialist Barbara Morgan, the teacher-turned-astronaut whose association with NASA began more than 20 years ago.

First motion out of the VAB was at 8:10 p.m. July 10, and the shuttle was hard down on the pad at 3:02 a.m. July 11. At far left is the rotating service structure, called the RSS, which can be rolled around to enclose the shuttle for access during processing. Between the RSS and the shuttle is the fixed service structure, topped by an 80-foot-tall lightning mast. Endeavour is scheduled to launch on mission STS-118 on Aug. 7. During the mission, Endeavour will carry into orbit the S5 truss, SPACEHAB module and external stowage platform 3. The mission is the 22nd flight to the International Space Station and will mark the first flight of Mission Specialist Barbara Morgan, the teacher-turned-astronaut whose association with NASA began more than 20 years ago. STS-118 will be the first flight since 2002 for Endeavour, which has undergone extensive modifications, including the addition of safety upgrades already added to orbiters Discovery and Atlantis.

KENNEDY SPACE CENTER, FLA. -- The dawn sky over the Atlantic Ocean reveals Space Shuttle Endeavour sitting on Launch Pad 39A. First motion out of the Vehicle Assembly Building was at 8:10 p.m. July 10, and the shuttle was hard down on the pad at 3:02 a.m. July 11. The orbiter access arm is already extended to the orbiter from the fixed service structure. Peering just above the solid rocket booster on the left is the 290-foot-tall water tank. It provides the deluge over the mobile launcher platform for sound suppression during liftoff. Endeavour is scheduled to launch on mission STS-118 on Aug. 7. During the mission, Endeavour will carry into orbit the S5 truss, SPACEHAB module and external stowage platform 3. The mission is the 22nd flight to the International Space Station and will mark the first flight of Mission Specialist Barbara Morgan, the teacher-turned-astronaut whose association with NASA began more than 20 years ago.

The orbiter access arm is already extended to the orbiter from the fixed service structure at left. On top of the structure is the 80-foot-tall lightning mast that helps provide protection from lightning on the pad. The shuttle sits on a mobile launcher platform. Part of the platform and seen below the orbiter's wings are the tail masts, which provide several umbilical connections to the orbiter, including a liquid-oxygen line through one and a liquid-hydrogen line through another.
