KENNEDY SPACE CENTER, FLA.  -  A closeup of crawler-transportation (CT) number 2 shows the new muffler system on the vehicle.  The CT also recently underwent modifications to the cab.   The CT is transporting a Mobile Launch Platform (MLP).  The CT moves Space Shuttle vehicles, situated on the MLP, between the VAB and launch pad.  Moving on four double-tracked crawlers, the CT uses a laser guidance system and a leveling system for the journey that keeps the top of a Space Shuttle vertical within plus- or minus-10 minutes of arc.  The system enables the CT-MLP-Shuttle to negotiate the ramp leading to the launch pads and keep the load level.  Unloaded, the CT weighs 6 million pounds.  Seen on top of the MLP are two tail service masts that support the fluid, gas and electrical requirements of the orbiter’s liquid oxygen and liquid hydrogen aft umbilicals.

KENNEDY SPACE CENTER, Fla. -- Resting atop the Mobile Launcher Platform, Space Shuttle Atlantis is viewed from a high level on the Fixed Service Structure. Seen is one of its solid rocket boosters and the external tank. Next to the wing of the orbiter is one of two tail service masts, which support the fluid, gas and electrical requirements of the orbiter’s liquid oxygen and liquid hydrogen aft T-0 umbilicals. On the horizon is the Atlantic Ocean. Atlantis will fly on mission STS-98, the seventh construction flight to the International Space Station, carrying the U.S. Laboratory, named Destiny. The lab has five system racks already installed inside the module. After delivery of electronics in the lab, electrically powered attitude control for Control Moment Gyroscopes will be activated. Atlantis is scheduled for launch no earlier than Jan. 19, 2001, with a crew of five KSC01pp0016

KENNEDY SPACE CENTER, Fla. -- Workers clean the mobile launcher platform on which sits Space Shuttle Atlantis. They are standing in front of one of two tail service masts on either side of the Shuttle, in front of each wing. The masts support the fluid, gas and electrical requirements of the orbiter’s liquid oxygen and liquid hydrogen aft T-0 umbilicals. Launch on mission STS-104 is scheduled for 5:04 a.m. July 12. The launch is the 10th assembly flight to the International Space Station. Along with a crew of five, Atlantis will carry the joint airlock module as primary payload KSC-01pp1274

KENNEDY SPACE CENTER, FLA.  -  Crawler-transporter (CT) number 2, moves away from the Vehicle Assembly Building with a Mobile Launcher Platform (MLP) on top on a test run to the launch pad.  The CT recently underwent modifications to the cab.  The CT moves Space Shuttle vehicles, situated on the MLP, between the VAB and launch pad.  Moving on four double-tracked crawlers, the CT uses a laser guidance system and a leveling system for the journey that keeps the top of a Space Shuttle vertical within plus- or minus-10 minutes of arc.  The system enables the CT-MLP-Shuttle to negotiate the ramp leading to the launch pads and keep the load level.  Unloaded, the CT weighs 6 million pounds.  Seen on top of the MLP are two tail service masts that support the fluid, gas and electrical requirements of the orbiter’s liquid oxygen and liquid hydrogen aft umbilicals.

CAPE CANAVERAL, Fla. --     Bathed in lights surrounding Launch Pad 39A and its structures at NASA's Kennedy Space Center, space shuttle Discovery is poised for launch on the STS-124 mission after rollback of the rotating service structure. First motion was at 8:33 p.m. and rollback was complete at 9:07 p.m.  The structure provides protected access to the shuttle for changeout and servicing of payloads at the pad. It is supported by a rotating bridge that pivots on a vertical axis on the west side of the pad's flame trench. After the RSS is rolled back, the orbiter is ready for fuel cell activation and external tank cryogenic propellant loading operations.  The pad is cleared to the perimeter gate for operations to fill the external tank with about 500,000 gallons of cryogenic propellants used by the shuttle’s main engines. This is done at the pad approximately eight hours before the scheduled launch.  Behind the shuttle is the orange external tank and the two solid rocket boosters (only one seen here).  Beneath the shuttle's starboard wing is one of two tail service masts, which provide several umbilical connections to the orbiter, including a liquid-oxygen line through one and a liquid-hydrogen line through another. The STS-124 mission is the second of three flights launching components to complete the Japan Aerospace Exploration Agency's Kibo laboratory.  The shuttle crew will install Kibo's large Japanese Pressurized Module and its remote manipulator system, or RMS.  The 14-day flight includes three spacewalks.  Launch is scheduled for 5:02 p.m. May 31. Photo credit: NASA/Troy Cryder KSC-08pd1505

CAPE CANAVERAL, Fla. -  At Launch Pad 39A at NASA's Kennedy Space Center in Florida, the payload canister arrives beneath the payload changeout room in the rotating service structure (left).  Space shuttle Atlantis is at right.  The two tail service masts on the mobile launcher platform flank the engines in front of the wings.  The canister carries a cargo of four carriers holding various equipment for the STS-125 mission aboard Atlantis to service NASA’s Hubble Space Telescope.  At the pad, the cargo will be moved into the Payload Changeout Room.  The changeout room is the enclosed, environmentally controlled portion of the rotating service structure that supports cargo delivery to the pad and subsequent vertical installation into the shuttle’s payload bay. Launch of Atlantis is targeted for Oct. 10.  Photo credit: NASA/Troy Cryder KSC-08pd2785
