KENNEDY SPACE CENTER, FLA. -- Following sunrise on a cloudy Florida day, Space Shuttle Atlantis awaits launch atop a mobile launch platform at Launch Pad 39A. Rollback of the pad's rotating service structure, or RSS, is one of the milestones in preparation for the launch of mission STS-117 on June 8. Rollback started at 10:56 p.m. EDT June 7 and was complete at 11:34 p.m. The RSS, the massive structure to the left of the shuttle, provides protected access to the orbiter for changeout and servicing of payloads at the pad. The structure is supported by a rotating bridge that pivots about a vertical axis on the side of the pad's flame trench. The hinge column rests on the pad surface and is braced to the fixed service structure. Support for the outer end of the bridge is provided by two eight-wheel, motor-driven trucks that move along circular twin rails installed flush with the pad surface. The track crosses the flame trench on a permanent bridge. The RSS is 102 feet long, 50 feet wide and 130 feet high. The structure has orbiter access platforms at five levels to provide access to the payload bay while the orbiter is being serviced in the RSS. Each platform has independent extendable planks that can be arranged to conform to a payload's configuration. This mission is the 118th shuttle flight and the 21st U.S. flight to the International Space Station and will deliver and install the S3/S4 truss segment, deploy a set of solar arrays and prepare them for operation.

KENNEDY SPACE CENTER, FLA. - Silhouetted against the rising sun, Space Shuttle Atlantis rolls toward Launch Pad 39B. First motion out of the Vehicle Assembly Building was 1:05 a.m. The shuttle sits on top of the mobile launcher platform, which in turn rests on the crawler-transporter. The slow speed of the crawler results in a 6-hour trek to the pad approximately 4 miles away. Atlantis' launch window begins Aug. 27 for an 11-day mission to the International Space Station. The STS-115 crew of six astronauts will continue construction of the station and install their cargo, the Port 3/4 truss segment with its two large solar arrays. Photo credit: NASA/George Shelton

CAPE CANAVERAL, Fla. – At NASA's Kennedy Space Center in Florida, space shuttle Atlantis is reflected in the still water of the turn basin as it makes its 3.4-mile trip, known as rollout, from the Vehicle Assembly Building to Launch Pad 39A.

KENNEDY SPACE CENTER, FLA. -- Space Shuttle Atlantis is captured as it lifts off Launch Pad 39A for a rocket ride into the sky and rendezvous with the International Space Station on mission STS-117. On the mobile launcher platform below Atlantis can be seen the jets of water flooding the surface for sound suppression. Beyond the pad on the horizon is the Atlantic Ocean. Liftoff of Atlantis was on-time at 7:38:04 p.m. EDT. The shuttle is delivering a new segment to the starboard side of the International Space Station's backbone, known as the truss. Three spacewalks are planned to install the S3/S4 truss segment, deploy a set of solar arrays and prepare them for operation. STS-117 is the 118th space shuttle flight, the 21st flight to the station, the 28th flight for Atlantis and the first of four flights planned for 2007.

KENNEDY SPACE CENTER, FLA. - Space Shuttle Atlantis sits on the hardstand of Launch Pad 39B after its nearly 8-hour rollout from the Vehicle Assembly Building. At left of the shuttle are the rotating service structure and fixed service structure. The slow speed of the crawler results in a 6- to 8-hour trek to the pad approximately 4 miles away. Atlantis' launch window begins Aug. 27 for an 11-day mission to the International Space Station. The STS-115 crew of six astronauts will continue construction of the station and install their cargo, the Port 3/4 truss segment with its two large solar arrays. Photo credit: NASA/Tony Gray

KENNEDY SPACE CENTER, FLA. -- After a nearly 5.3 million mile round trip to the International Space Station, space shuttle Atlantis slows down with the aid of a drag chute after landing on Runway 15 of the Shuttle Landing Facility at NASA's Kennedy Space Center. In the background is the Vehicle Assembly Building. The shuttle landed on orbit 202 to complete the 13-day STS-122 mission. Main gear touchdown was 9:07:10 a.m. Nose gear touchdown was 9:07:20 a.m. Wheel stop was at 9:08:08 a.m. Mission elapsed time was 12 days, 18 hours, 21 minutes and 44 seconds. During the mission, Atlantis' crew installed the new Columbus laboratory, leaving a larger space station and one with increased science capabilities. The Columbus Research Module adds nearly 1,000 cubic feet of habitable volume and affords room for 10 experiment racks, each an independent science lab. Photo credit: NASA/Kenny Allen, Robert Murray

KENNEDY SPACE CENTER, FLA. -- Rollback of the rotating service structure, or RSS, begins on Launch Pad 39A, revealing Space Shuttle Atlantis, bathed in lights. Rollback is one of the milestones in preparation for the launch of mission STS-117 on June 8 and started at 10:56 p.m. EDT. The RSS provides protected access to the orbiter for changeout and servicing of payloads at the pad. The structure is supported by a rotating bridge that pivots about a vertical axis on the side of the pad's flame trench. The hinge column rests on the pad surface and is braced to the fixed service structure. Support for the outer end of the bridge is provided by two eight-wheel, motor-driven trucks that move along circular twin rails installed flush with the pad surface. The track crosses the flame trench on a permanent bridge. The RSS is 102 feet long, 50 feet wide and 130 feet high. The structure has orbiter access platforms at five levels to provide access to the payload bay while the orbiter is being serviced in the RSS. Each platform has independent extendable planks that can be arranged to conform to a payload's configuration. This mission is the 118th shuttle flight and the 21st U.S. flight to the International Space Station and will deliver and install the S3/S4 truss segment, deploy a set of solar arrays and prepare them for operation.

KENNEDY SPACE CENTER, FLA. -- Space shuttle Atlantis is lifted into the upper levels of the Vehicle Assembly Building at NASA's Kennedy Space Center. Atlantis will be lowered into high bay 3 and mated with the external tank and solid rocket boosters designated for mission STS-122, already secured atop a mobile launcher platform. On this mission, Atlantis will deliver the Columbus module to the International Space Station. The European Space Agency's largest contribution to the station, Columbus is a multifunctional, pressurized laboratory that will be permanently attached to U.S. Node 2, called Harmony. The module is approximately 23 feet long and 15 feet wide, allowing it to hold 10 large racks of experiments. The laboratory will expand the research facilities aboard the station, providing crew members and scientists from around the world the ability to conduct a variety of experiments in the physical, materials and life sciences.

KENNEDY SPACE CENTER, FLA. - Space Shuttle Atlantis rolls up the ramp to Launch Pad 39B atop the crawler-transporter. The crawler has a leveling system designed to keep the top of the space shuttle vertical while negotiating the 5-percent grade leading to the top of the launch pad. Also, a laser docking system provides almost pinpoint accuracy when the crawler and mobile launcher platform are positioned at the launch pad. At right are the open rotating service structure and the fixed service structure topped by the 80-foot lightning mast. The shuttle had been moved off the launch pad due to concerns about the impact of Tropical Storm Ernesto, expected within 24 hours. The forecast of lesser winds expected from Ernesto and its projected direction convinced Launch Integration Manager LeRoy Cain and Shuttle Launch Director Mike Leinbach to return the shuttle to the launch pad.

KENNEDY SPACE CENTER, FLA. - Reflected in the nearby pool of water, Space Shuttle Atlantis arrives on the hard stand on Launch Pad 39B, propelled by the crawler-transporter. At right is the 290-foot high, 300,000-gallon water tank that aids in sound suppression during launch. The water releases just prior to the ignition of the shuttle engines and flows through 7-foot-diameter pipes for about 20 seconds, pouring into 16 nozzles atop the flame deflectors and from outlets in the main engines exhaust hole in the mobile launcher platform. Atop the fixed service structure is the 80-foot lightning mast that helps provide lightning protection.
