VANDENBERG AIR FORCE BASE, Calif. -- At Vandenberg Air Force Base in the early '80s, the Space Shuttle Enterprise undergoes Pathfinder fit checks at a tower. The Enterprise was built as a test vehicle and was not equipped for spaceflight. Enterprise eventually became the property of the Smithsonian Institution. Vandenberg AFB is located on the Central Coast of California about 150 miles northwest of Los Angeles. The property is comprised of parts of five Mexican land grants and a sixth grant that was transferred virtually intact to the Army. Vandenberg now is operated by the 30th Space Wing, and is the only military installation in the United States from which unmanned government and commercial satellites are launched into polar orbit. It is also the only site from which intercontinental ballistic missiles ICBMs are launched toward the Kwajalein Atoll to verify weapon systems performance. Vandenberg's military service dates back to 1941, when known as Camp Cooke it served as an Army training facility for armored and infantry troops. The main camp closed in June 1946 and was reactivated in August 1950 after the outbreak of the Korean War. The 13th and 20th Armored Divisions and the 40th, 44th, 86th, and 91st Infantry Divisions trained at Cooke. With the advent of the missile age in the 1950s, the Air Force persuaded Secretary of Defense Charles E. Wilson to direct the Army to transfer 64,000 acres of North Camp Cooke to the Air Force for use as a missile launch and training base. In 1958, Camp Cooke was renamed Vandenberg Air Force Base in honor of the late General Hoyt S. Vandenberg, second Air Force Chief of Staff of the United States Air Force and chief architect of today's modern Air Force. Photo Credit: NASA KSC-99PP-1051

CAPE CANAVERAL, Fla. - The giant external fuel tank and twin solid rocket boosters attached to space shuttle Endeavour bask in the sunlight as the rotating service structure (RSS) moves away on Launch Pad 39A at NASA's Kennedy Space Center in Florida. The structure provides weather protection and access to the shuttle while it awaits lift off on the pad. RSS "rollback," as it's called, began at 11:44 a.m. EDT on May 15 and was completed at 12:24 p.m. STS-134 will deliver the Alpha Magnetic Spectrometer-2 (AMS), Express Logistics Carrier-3, a high-pressure gas tank and additional spare parts for the Dextre robotic helper to the International Space Station. May 16 at 8:56 a.m. will be the second launch attempt for Endeavour. The first attempt on April 29 was scrubbed because of an issue associated with a faulty power distribution box called the aft load control assembly-2 (ALCA-2). STS-134 will be the final spaceflight for Endeavour. For more information visit, www.nasa.gov/mission_pages/shuttle/shuttlemissions/sts134/index.html. Photo credit: NASA/Jack Pfaller KSC-2011-3551

KENNEDY SPACE CENTER, FLA. -- The blue cones of light, known as shock or mach diamonds, beneath Space Shuttle Discovery's main engines confirm its rapid rise into the night sky after liftoff on mission STS-116. Mach diamonds are a formation of shock waves in the exhaust plume of an aerospace propulsion system. Liftoff occurred on time at 8:47 p.m. EST. This was the second launch attempt for mission STS-116. The first launch attempt on Dec. 7 was postponed due a low cloud ceiling over Kennedy Space Center. This is Discovery's 33rd mission and the first night launch since 2003. The 20th shuttle mission to the International Space Station, STS-116 carries another truss segment, P5. It will serve as a spacer, mated to the P4 truss that was attached in September. After installing the P5, the crew will reconfigure and redistribute the power generated by two pairs of U.S. solar arrays. Landing is expected Dec. 21 at KSC.

KENNEDY SPACE CENTER, FLA. -- Cameras are prepared to record the launch of Space Shuttle Atlantis from Launch Pad 39A following sunrise on a cloudy Florida day. 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.

CAPE CANAVERAL, Fla. -- Space shuttle Endeavour, attached to its external fuel tank and solid rocket boosters atop a crawler-transporter, is ready for its slow move from High Bay 3 in the Vehicle Assembly Building to Launch Pad 39A at NASA's Kennedy Space Center in Florida. The 3.4-mile trek, known as "rollout," will take about seven hours to complete. This is the final scheduled rollout for Endeavour. Endeavour and its six STS-134 crew members will deliver the Express Logistics Carrier-3, Alpha Magnetic Spectrometer-2 (AMS), a high-pressure gas tank, additional spare parts for the Dextre robotic helper and micrometeoroid debris shields to the International Space Station on the shuttle's final spaceflight. Launch is targeted for April 19 at 7:48 p.m. EDT. For more information visit, www.nasa.gov/mission_pages/shuttle/shuttlemissions/sts134/index.html. Photo credit: NASA/Jim Grossmann KSC-2011-2214

CAPE CANAVERAL, Fla. -- Media representatives participate in a Now and Future Tour at NASA's Kennedy Space Center in Florida. Here, they make a stop at the Launch Pad 39B, which is being restructured for future use. Its new design will feature a "clean pad" for rockets to come with their own launcher, making it more versatile for a number of vehicles. Leading the tour is Jose Perez-Morales, NASA's pad B project manager. Other stops along the tour included Orbiter Processing Facility-2 (OPF-2) and the Shuttle Landing Facility (SLF). OPF-2 is where shuttle Discovery is being prepared for future public display at the Smithsonian's National Air and Space Museum Steven F. Udvar-Hazy Center in Chantilly, Va. The SLF's runway could be used for private companies and government agencies to host a diversity of launch systems, including orbital and suborbital flights.

This aerial photo captures many of the facilities involved in Space Shuttle launches. At center is the Vehicle Assembly Building (VAB). The curved road on the near side is the newly restored crawlerway leading into the VAB high bay 2, where a mobile launcher platform/crawler-transporter currently sits. The road restoration and high bay 2 are part of KSC’s Safe Haven project, enabling the storage of orbiters during severe weather. The crawlerway also extends from the east side of the VAB out to the two Space Shuttle launch pads. In the distance is the Atlantic Ocean. To the right of the far crawlerway is the turn basin, into which ships tow the barge for offloading new external tanks from Louisiana KSC-00pp0735

CAPE CANAVERAL, Fla. -- Space shuttle Discovery approached the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida. The 3.4-mile trek, called rollback, from Launch Pad 39A began at 10:48 p.m. yesterday and took about eight hours. Next, Discovery's external fuel tank will be examined and foam reapplied where 89 sensors were installed on the tank's aluminum skin for an instrumented tanking test on Dec. 17. The sensors were used to measure changes in the tank as super-cold propellants were pumped in and drained out. Data and analysis from the test will be used to determine what caused the tops of two, 21-foot-long support beams, called stringers, on the outside of the intertank to crack during fueling on Nov. 5. Discovery's next launch opportunity to the International Space Station on the STS-133 mission is no earlier than Feb. 3, 2011.

CAPE CANAVERAL, Fla. -- Space shuttle Discovery looms against the pre-dawn, cloud-streaked sky as it makes the slow 3.4-mile journey to Launch Pad 39A. The shuttle sits atop the mobile launcher platform, which are being moved by the massive crawler-transporter beneath. First motion out of the Vehicle Assembly Building was at 5:17 a.m. EST. Discovery is targeted to launch to the International Space Station Feb. 12. During Discovery's 14-day mission, the crew will install the S6 truss segment and its solar arrays to the starboard side of the station, completing the station's backbone, or truss, enabling a six-person crew to live there starting in May.
