KENNEDY SPACE CENTER, FLA. - After its overnight rollout from the Vehicle Assembly Building, Space Shuttle Atlantis rests on the hard stand on Launch Pad 39B. The shuttle sits on top of the mobile launcher platform. The crawler, which transported it, is still underneath. To the left is the rotating service structure, with the payload changeout room (PCR) open. When the shuttle's payload is transported to the pad, it will be lifted into the PCR, the service structure will rotate to enclose the shuttle and the payload will be installed in Atlantis' payload bay. 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.

CAPE CANAVERAL, Fla. –At NASA's Kennedy Space Center in Florida, the crawler-transporter delivers space shuttle Discovery atop the mobile launcher platform onto Launch Pad 39A. Traveling from the Vehicle Assembly Building, the shuttle took nearly 12 hours on the journey as technicians stopped several times to clear mud from the crawler's treads and bearings caused by the waterlogged crawlerway. First motion out of the VAB was at 2:07 a.m. EDT Aug. 4. Rollout was delayed approximately 2 hours due to lightning in the area. In the background is the blue water of the Atlantic Ocean. At left is the White Room at the end of the orbiter access arm. When in place against shuttle, the White Room provides entry into the cockpit. Discovery's 13-day flight will deliver a new crew member and 33,000 pounds of equipment to the International Space Station. The equipment includes science and storage racks, a freezer to store research samples, a new sleeping compartment and the COLBERT treadmill. Launch of Discovery on its STS-128 mission is targeted for late August. Photo credit: NASA/Troy Cryder KSC-2009-4423

KENNEDY SPACE CENTER, Fla. -- With the American flag flapping in the morning breeze, Space Shuttle Discovery, across the turn basin, makes its crawl to Launch Pad 39B (background, left) atop the mobile launcher platform and crawler transporter. Once at the pad, the orbiter, external tank and solid rocket boosters will undergo final preparations for the STS-103 launch targeted for Dec. 6, 1999, at 2:37 a.m. EST. The mission is a "call-up" due to the need to replace and repair portions of the Hubble Space Telescope. Although Hubble is operating normally and conducting its scientific observations, only three of its six gyroscopes are working properly. Four EVA's are planned to make the necessary repairs and replacements on the telescope. The STS-103 crew members are Commander Curtis L. Brown Jr., Pilot Scott J. Kelly, Steven L. Smith, C. Michael Foale (Ph.D.), John M. Grunsfeld (Ph.D.), and Claude Nicollier of Switzerland and Jean-François Clervoy of France, both with the European Space Agency. KSC-99pp1303

KENNEDY SPACE CENTER, FLA. -- Just after sunrise, Space Shuttle Atlantis, mounted on a mobile launch platform, rolls a second time to Launch Pad 39A atop a crawler transporter. First motion out of the Vehicle Assembly Building was at 5:02 a.m. EDT. In late February, while Atlantis was on the launch pad, Atlantis' external tank received hail damage during a severe thunderstorm that passed through the Kennedy Space Center Launch Complex 39 area. The hail caused visible divots in the giant tank's foam insulation, as well as minor surface damage to about 26 heat shield tiles on the shuttle's left wing. The shuttle was returned to the VAB for repairs. The launch of Space Shuttle Atlantis on mission STS-117 is now targeted for June 8. A flight readiness review will be held on May 30 and 31.

CAPE CANAVERAL, Fla. -- At NASA's Kennedy Space Center in Florida, crawler-transporter No. 2 moves a space shuttle era mobile launcher platform down the gravel crawler way at Launch Pad 39A. The activity was part of testing to check out recently completed modifications to ensure its ability to carry launch vehicles such as the space agency's Space Launch System heavy-lift rocket to the pad. NASA's Ground Systems Development and Operations Program is leading the 20-year life-extension project for the crawler. A pair of behemoth machines called crawler-transporters has carried the load of taking rockets and spacecraft to the launch pad for more than 40 years at NASA’s Kennedy Space Center in Florida. Each weighing six and a half million pounds and larger in size than a professional baseball infield, the crawler-transporters are powered by locomotive and large electrical power generator engines. The crawler-transporters will stand ready to keep up the work for the next generation of launch vehicles to lift astronauts into space.

CAPE CANAVERAL, Fla. – Inside the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida, preparations are underway to lower crawler-transporter 2, or CT-2, from jack stands so that work can begin to re-install the large crawler tracks. The crawler is being prepared for rollout in January 2014 to test the new bearings that were recently installed. 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.

KENNEDY SPACE CENTER, FLA. -- At a juncture in the crawlerway, a crawler transporter slowly moves Space Shuttle Discovery, with its external tank and solid rocket boosters, to High Bay 1 of the Vehicle Assembly Building to repair damage to the external tank's foam insulation caused by hail. The necessary repair work could not be performed at Pad 39B due to limited access to the damaged areas. The work is expected to take two to three days, allowing Discovery to roll back to the pad by midweek for launch of mission STS-96, the 94th launch in the Space Shuttle Program. This is only the 13th time since 1981 that a Shuttle has had to be rolled back from the pad. Liftoff will occur no earlier than May 27. STS-96 is a logistics and resupply mission for the International Space Station, carrying such payloads as a Russian crane, the Strela; a U.S.-built crane; the Spacehab Oceaneering Space System Box (SHOSS), a logistics items carrier; and STARSHINE, a student-shared experiment KSC-99pp0533

KENNEDY SPACE CENTER, FLA. -- Towering atop the mobile launcher platform and crawler transporter, Space Shuttle Discovery rolls out of the Vehicle Assembly Building on its way to Launch Pad 39B which is 4.2 miles (6.8 kilometers) away. While at the pad, the orbiter, external tank and solid rocket boosters will undergo final preparations for the STS-103 launch targeted for Dec. 6, 1999, at 2:37 a.m. EST. The mission is a "call-up" due to the need to replace portions of the pointing system the gyros which have begun to fail on the Hubble Space Telescope. Although Hubble is operating normally and conducting its scientific observations, only three of its six gyroscopes are working properly. The gyroscopes allow the telescope to point at stars, galaxies and planets. The STS-103 crew will also be installing a Fine Guidance Sensor, a new enhanced computer, a solid-state digital recorder, and a new spare transmitter to replace older equipment, and replacing degraded insulation on the telescope with new thermal insulation. The crew will also install a Battery Voltage/Temperature Improvement Kit to protect the spacecraft batteries from overcharging and overheating when the telescope goes into a safe mode. Four EVA's are planned to make the necessary repairs and replacements on the telescope. Comprising the STS-103 crew are Commander Curtis L. Brown Jr., Pilot Scott J. Kelly, Mission Specialist Steven L. Smith, Mission Specialist C. Michael Foale (Ph.D.), Mission Specialist John M. Grunsfeld (Ph.D.), Mission Specialist Claude Nicollier of Switzerland, with the European Space Agency, and Mission Specialist Jean-François Clervoy of France, with the European Space Agency KSC-99padig031

KENNEDY SPACE CENTER, FLA. - A serene scene surrounds Space Shuttle Atlantis as it begins rolling off Launch Pad 39B to return to the Vehicle Assembly Building. First motion off the pad was at 10:04 a.m. EDT. The crawler is 131 feet long, 113 feet wide and 20 feet high. It weights 5.5 million pounds unloaded. The combined weight of crawler, mobile launcher platform and a space shuttle is 12 million pounds. Unloaded, the crawler moves at 2 mph. Loaded, the snail's pace slows to 1 mph. The rollback is a safety precaution as the area waits for the arrival of Tropical Storm Ernesto. The storm is forecast to be bringing 58-mph to 70-mph winds in the next 24 hours. The shuttle will be moved into high bay 2, on the southwest side of the VAB, for protection from the storm. Photo credit: NASA/Ken Thornsley KSC-06pd1980

KENNEDY SPACE CENTER, FLA. - A late-day sun spotlights Space Shuttle Atlantis as it 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 left 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.

CAPE CANAVERAL, Fla. -- United Space Alliance Project Manager Mike Parrish sits in the driver's position of crawler-transporter No. 2 which has been undergoing modifications inside high bay 2 of the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida. The upgrades are designed to ensure the crawler-transporter can carry launch vehicles such as the space agency's Space Launch System heavy-lift rocket to the launch pad. NASA's Ground Systems Development and Operations Program is leading the 20-year life-extension project for the crawler. A pair of behemoth machines called crawler-transporters has carried the load of taking rockets and spacecraft to the launch pad for more than 40 years at NASA’s Kennedy Space Center in Florida. Each the size of a baseball infield and powered by locomotive and large electrical power generator engines, the crawler-transporters will stand ready to keep up the work for the next generation of launch vehicles projects to lift astronauts into space.

KENNEDY SPACE CENTER, FLA. -- Under a feather-painted sky, Space Shuttle Atlantis, mounted on a mobile launch platform atop a crawler transporter, creeps up the ramp to Launch Pad 39A. This is the second rollout for the shuttle. First motion out of the Vehicle Assembly Building was at 5:02 a.m. EDT. In late February, while Atlantis was on the launch pad, Atlantis' external tank received hail damage during a severe thunderstorm that passed through the Kennedy Space Center Launch Complex 39 area. The hail caused visible divots in the giant tank's foam insulation, as well as minor surface damage to about 26 heat shield tiles on the shuttle's left wing. The shuttle was returned to the VAB for repairs. The launch of Space Shuttle Atlantis on mission STS-117 is now targeted for June 8. A flight readiness review will be held on May 30 and 31.

The STS-95 Space Shuttle Discovery sits on the Mobile Launch Platform, still atop the crawler transporter, at Launch Pad 39B. To its left is the Fixed Service Structure that provides access to the orbiter and the Rotating Service Structure. To its right is the elevated water tank, with a capacity of 300,000 gallons. Part of the sound suppression water system, the tank stands 290 feet high on the northeast side of the pad. Water from the tank is released just before ignition of the orbiter's three main engines and twin solid rocket boosters. The entire system reduces the acoustical levels within the orbiter's payload bay to an acceptable 142 decibels. Beyond the orbiter is seen the Atlantic Ocean. While at the launch pad, the orbiter, external tank and solid rocket boosters will undergo final preparations for the launch, scheduled to lift off Oct. 29. The mission includes research payloads such as the Spartan solar-observing deployable spacecraft, the Hubble Space Telescope Orbital Systems Test Platform, the International Extreme Ultraviolet Hitchhiker, as well as the SPACEHAB single module with experiments on space flight and the aging process KSC-98pc1110

KENNEDY SPACE CENTER, FLA. -- Towering atop the mobile launcher platform and crawler transporter, Space Shuttle Discovery rolls out of the Vehicle Assembly Building on its way to Launch Pad 39B which is 4.2 miles (6.8 kilometers) away. While at the pad, the orbiter, external tank and solid rocket boosters will undergo final preparations for the STS-103 launch targeted for Dec. 6, 1999, at 2:37 a.m. EST. The mission is a "call-up" due to the need to replace portions of the pointing system the gyros which have begun to fail on the Hubble Space Telescope. Although Hubble is operating normally and conducting its scientific observations, only three of its six gyroscopes are working properly. The gyroscopes allow the telescope to point at stars, galaxies and planets. The STS-103 crew will also be installing a Fine Guidance Sensor, a new enhanced computer, a solid-state digital recorder, and a new spare transmitter to replace older equipment, and replacing degraded insulation on the telescope with new thermal insulation. The crew will also install a Battery Voltage/Temperature Improvement Kit to protect the spacecraft batteries from overcharging and overheating when the telescope goes into a safe mode. Four EVA's are planned to make the necessary repairs and replacements on the telescope. Comprising the STS-103 crew are Commander Curtis L. Brown Jr., Pilot Scott J. Kelly, Mission Specialist Steven L. Smith, Mission Specialist C. Michael Foale (Ph.D.), Mission Specialist John M.

KENNEDY SPACE CENTER, FLA. -- A technician steadies a jacking, equalization and leveling (JEL) cylinder and bearing from Crawler-Transporter No. 2 as it is lowered by a crane to a position on the ground. During routine maintenance inspections last week, technicians removed two of the 16 JEL cylinders on the crawler to gain access to the bearings and found three of the four bearings cracked. Further eddy current inspections indicated that cracks are present on 15 of the bearings. There are 16 cylinders and 32 bearings per crawler. Engineers are evaluating the situation to determine the cause of the cracks and an appropriate solution to the problem. KSC-02pd1185
