CAPE CANAVERAL, Fla. – Near the Vehicle Assembly Building, or VAB, at NASA’s Kennedy Space Center in Florida, old roller shaft bearing assembly parts that were removed from crawler-transporter 2, or CT-2, have been discarded. Inside the VAB, new roller shaft bearings will be installed on CT-2. Work continues in high bay 2 to upgrade CT-2. The modifications are designed to ensure CT-2’s ability to transport launch vehicles currently in development, such as the agency’s Space Launch System, to the launch pad. The Ground Systems Development and Operations Program office at Kennedy is overseeing the upgrades. For more than 45 years the crawler-transporters were used to transport the mobile launcher platform and the Apollo-Saturn V rockets and, later, space shuttles to Launch Pads 39A and B.

LAS VEGAS -- The Boeing Company tests the forward heat shield FHS jettison system of its CST-100 spacecraft at the Bigelow Aerospace facility in Las Vegas as part of an agreement with NASA's Commercial Crew Program CCP during Commercial Crew Development Round 2 CCDev2) activities. The FHS will protect the spacecraft's parachutes, rendezvous-and-docking sensor packages, and docking mechanism during ascent and re-entry. During a mission to low Earth orbit, the shield will be jettisoned after re-entry heating, allowing the spacecraft's air bags to deploy for a safe landing. In 2011, NASA selected Boeing for CCDev2 to mature the design and development of a crew transportation system with the overall goal of accelerating a United States-led capability to the International Space Station. The goal of CCP is to drive down the cost of space travel as well as open up space to more people than ever before by balancing industry’s own innovative capabilities with NASA's 50 years of human spaceflight experience. Six other aerospace companies also were selected to mature launch vehicle and spacecraft designs under CCDev2, including Alliant Techsystems Inc. ATK, Excalibur Almaz Inc., Blue Origin, Sierra Nevada Corp. SNC, Space Exploration Technologies SpaceX, and United Launch Alliance ULA. For more information, visit www.nasa.gov/commercialcrew.

CAPE CANAVERAL, Fla. -- At NASA's Kennedy Space Center in Florida, Mobile Launcher Platform-3 (MLP), which supported space shuttle Atlantis for its final flight to the International Space Station on the STS-135 mission, is taking its last journey from Launch Pad 39A to the Vehicle Assembly Building (VAB). A massive crawler-transporter positioned under the MLP -- the last mobile launcher platform to launch a shuttle, begins the trek back to the VAB. A water truck leads the way spraying water on the dry crawlerway to reduce dust particles in the air. For more than 40 years, the MLPs have traveled between the massive VAB to both launch pads at Launch Complex 39, and then returned to the VAB for future use. MLP-3 was first used to launch Columbia on the STS-32 mission on Jan. 9, 1990. Photo credit: NASA/Kim Shiflett KSC-2011-5590

CAPE CANAVERAL, Fla. -- At NASA's Kennedy Space Center in Florida, shuttle Discovery pauses in between Orbiter Processing Facility-3 and the Vehicle Assembly Building (VAB) during a move called "rollover." Once inside the VAB, the shuttle will be joined to its solid rocket boosters and external fuel tank. 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.

CAPE CANAVERAL, Fla. – At NASA’s Kennedy Space Center in Florida, workers pull cables between the 26th and 29th floors of high bay 3 in the 525-foot-tall Vehicle Assembly Building, or VAB, during part of a centerwide refurbishment initiative under the Ground Systems Development and Operations GSDO Program. The cable replacement project is under way in high bays 1 and 3 on the east side of the building, facing Launch Complex 39’s pads A and B. Approximately 150 miles of existing Apollo/shuttle era cabling is being removed to make room for installation of state-of-the-art command, communication and control systems that will be needed by future users to perform vehicle testing and verification prior to rollout to the launch pad.

CAPE CANAVERAL, Fla. – Tugboats safely deliver the Pegasus barge, carrying external tank 134, to the dock in the turn basin near the Vehicle Assembly Building, or VAB, at NASA's Kennedy Space Center in Florida. Pegasus arrived in Florida after an ocean voyage towed by a solid rocket booster retrieval ship from NASA's Michoud Assembly Facility near New Orleans. After Pegasus docks in the turn basin, the fuel tank will be offloaded and transported into the VAB. ET-134 will be used to launch space shuttle Endeavour on the STS-130 mission to the International Space Station. Launch is targeted for Feb. 4, 2010.

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. 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.

CAPE CANAVERAL, Fla. -- This panoramic view shows NASA's new mobile launcher, or ML, support structure standing tall at NASA's Kennedy Space Center in Florida. It took about two years to construct the launcher in the Mobile Launcher Park site, north of the Vehicle Assembly Building, or VAB. The 355-foot-tall structure will support NASA's future human spaceflight program. The base of the launcher is lighter than space shuttle mobile launcher platforms so the crawler-transporter can pick up the heavier load of the tower and a taller rocket. The next step will be to add ground support equipment, such as umbilicals and access arms, for future rocket launches. For information on NASA's future plans, visit www.nasa.gov.
