KENNEDY SPACE CENTER, FLA. - Crawler-transporter No. 2 nears Launch Pad 39B (in the background, right). The tip of the orange external tank can be seen above the rotating service structure surrounding the shuttle. The crawler is being moved nearby in the event the mission management team decides to roll back Space Shuttle Atlantis due to Hurricane Ernesto. The hurricane has been forecast on a heading north and east from Cuba, taking it along the eastern coast of Florida. NASA's lighted launch window extends to Sept. 13, but mission managers are hoping to launch on mission STS-115 by Sept. 7 to avoid a conflict with a Russian Soyuz rocket also bound for the International Space Station. 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.

KENNEDY SPACE CENTER, FLA. -Crawler-transporter (CT) number 2, moves away from the Vehicle Assembly Building, with a Mobile Launcher Platform on top, on a test run to the launch pad. The CT recently underwent modifications to the cab. The CT moves Space Shuttle vehicles 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.

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. From inside the viewing room of the Launch Control Center, KSC employees watch Space Shuttle Discovery as it creeps along the crawlerway toward the horizon, and Launch Pad 39B at NASAs Kennedy Space Center. First motion of the Shuttle out of the Vehicle Assembly Building (VAB) was at 2:04 p.m. EDT. The Mobile Launcher Platform is moved by the Crawler-Transporter underneath. The Crawler is 20 feet high, 131 feet long and 114 feet wide. It moves on eight tracks, each containing 57 shoes, or cleats, weighing one ton each. Loaded with the Space Shuttle, the Crawler can move at a maximum speed of approximately 1 mile an hour. A leveling system in the Crawler keeps the Shuttle vertical while negotiating the 5 percent grade leading to the top of the launch pad. Launch of Discovery on its Return to Flight mission, STS-114, is targeted for May 15 with a launch window that extends to June 3. During its 12-day mission, Discoverys seven-person crew will test new hardware and techniques to improve Shuttle safety, as well as deliver supplies to the International Space Station. Discovery was moved on March 29 from the Orbiter Processing Facility to the VAB and attached to its propulsion elements, a redesigned ET and twin SRBs.

Space Shuttle Crawler Transporter Sound Attenuation Study
NASA Technical Reports Server (NTRS)
Margasahayam, Ravi N.; MacDonald, Rod; Faszer, Clifford
2004-01-01
The crawler transporter (CT) is the world's largest tracked vehicle known, weighing 6 million pounds with a length of 131 feet and a width of 113 feet. The Kennedy Space Center (KSC) has two CTs that were designed and built for the Apollo program in the 1960's, maintained and retrofitted for use in the Space Shuttle program. As a key element of the Space Shuttle ground systems, the crawler transports the entire 12-million-pound stack comprising the orbiter, the mobile launch platform (MLP), the external tank (ET), and the solid rocket boosters (SRB) from the Vehicle Assembly Building (VAB) to the launch pad. This rollout, constituting a 3.5-5.0-mile journey at a top speed of 0.9 miles-per-hour, requires over 8 hours to reach either Launch Complex 39A or B. This activity is only a prelude to the spectacle of sound and fury of the Space Shuttle launch to orbit in less than 10 minutes and traveling at orbital velocities of Mach 24. This paper summarizes preliminary results from the Crawler Transporter Sound Attenuation Study, encompassing test and engineering analysis of significant sound sources to measure and record full frequency spectrum and intensity of the various noise sources and to analyze the conditions of vibration. Additionally, data such as ventilation criteria, plus operational procedures were considered to provide a comprehensive noise suppression design for implementation. To date, sound attenuation study and results on Crawler 2 have shown significant noise reductions ranging from 5 to 24 dBA.

KENNEDY SPACE CENTER, FLA. -- Space Shuttle Endeavour and the Mobile Launcher Platform (MLP) start backing through the gate to Launch Pad 39B after a cracked cleat was discovered on the crawler-transporter. Workers near the pad (behind the crawler track) look at the cleats. The vehicle, which moves the MLP and Shuttle at about 1 mph, 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 pad. When the Shuttle-MLP are back on level ground, the crawler tracks will be inspected and the broken cleat repaired. Endeavour is scheduled to be launched Nov. 30 at 10:01 p.m. EST on mission STS-97, the sixth construction flight to the International Space Station. Its payload includes the P6 Integrated Truss Structure and a photovoltaic (PV) module, with giant solar arrays that will provide power to the Station. The mission includes two spacewalks to complete the solar array connections

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.

The crawler-transporter carries its cargo at 1 mph, taking about five hours to cover the 3.4 miles from the Vehicle Assembly Building to the launch pad. A leveling system on the crawler-transporter keeps the top of the Space Shuttle vertical, especially negotiating the ramp leading to the launch pads and when it is raised and lowered on pedestals at the pad. Liftoff of Atlantis on mission STS-101 is scheduled for April 17 at 7:03 p.m. EDT. STS-101 is a logistics and resupply mission for the International Space Station, to restore full redundancy to the International Space Station power system in preparation for the arrival of the next pressurized module, the Russian-built Zvezda

KENNEDY SPACE CENTER, FLA. - Inside the cab of crawler-transporter (CT) number 2, driver Sam Dove, with United Space Alliance, operates the vehicle on a test run to the launch pad. The CT 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.

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. The shuttle nears the flame trench, which channels the flames and smoke exhaust of the shuttle's solid rocket boosters away from the space shuttle during liftoff. 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. 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.

CAPE CANAVERAL, Fla. – Sitting on top of the mobile launcher platform, space shuttle Discovery straddles the flame trench, which channels the flames and smoke exhaust of the shuttle's solid rocket boosters away from the space shuttle during liftoff, on Launch Pad 39A at NASA's Kennedy Space Center in Florida. 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. Discovery was secured, or "hard down" to Launch Pad 39A at 1:50 p.m. EDT. "Hard down" means that the mobile launcher platform, or MLP, is sitting on the pedestals on the pad, and the crawler has been jacked down, thus transferring the weight of the MLP from the crawler to the pad pedestals. 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.

STS-96 Space Shuttle Discovery rolls back to Launch Pad 39B
NASA Technical Reports Server (NTRS)
1999-01-01
Space Shuttle Discovery makes the climb to Launch Pad 39B aboard the mobile launcher platform and crawler transporter. The crawler is able to keep its cargo level during the move up the five percent grade, not varying from the vertical more than the diameter of a soccer ball. At right are the rotating and fixed service structures which will be used during prelaunch preparations at the pad. Earlier in the week, the Shuttle was rolled back to the VAB from the pad to repair hail damage on the external tank's foam insulation. Mission STS-96, the 94th launch in the Space Shuttle Program, is scheduled for liftoff May 27 at 6:48 a.m. EDT. 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.

Space Shuttle Crawler Transporter Truck Shoe Qualification Tests and Analyses for Return-to-Flight
NASA Technical Reports Server (NTRS)
Margasahayam, Ravi N.; Meyer, Karl A.; Burton, Roy C.; Gosselin, Armand M.
2005-01-01
A vital element to Launch Complex 39 (LC39) and NASA's Kennedy Space Center (KSC) mobile launch transfer operation is a 3 million kilogram behemoth known as the Crawler Transporter (CT). Built in the 1960's, two CT's have accumulated over 1700+ miles each and have been used for the Apollo and the Space Shuttle programs. Recent observation of fatigue cracks on the CT shoes led to a comprehensive engineering, structural and metallurgical evaluation to assess the root cause that necessitated procurement of over 1000 new shoes. This paper documents the completed dynamic and compression tests on the old and new shoes respectively, so as to certify them for Space Shuttle's return-to-flight (RTF). Measured strain data from the rollout tests was used to develop stress/loading spectra and static equivalent load for qualification testing of the new shoes. Additionally, finite element analysis (FEA) was used to conduct sensitivity analyses of various contact parameters and structural characteristics for acceptance of new shoes.

CAPE CANAVERAL, Fla. - Despite the incline, space shuttle Atlantis remains on a level plane as it rolls off Launch Pad 39A at NASA's Kennedy Space Center in Florida. First motion was at 6:48 a.m. EDT. The crawler-transporter underneath the mobile launcher platform maintains the level plane through a leveling system designed to keep the top of the space shuttle vehicle vertical. This system also provides the leveling operations required to negotiate the 5-percent ramp leading to the launch pads. Atlantis is rolling back to the Vehicle Assembly Building to await launch on its STS-125 mission to repair NASA's Hubble Space Telescope. Atlantis' targeted launch on Oct. 14 was delayed when a system that transfers science data from the orbiting observatory to Earth malfunctioned on Sept. 27. The new target launch date is under review. The space shuttle is mounted on a Mobile Launcher Platform and will be delivered to the Vehicle Assembly Building atop a crawler transporter. traveling slower than 1 mph during the 3.4-mile journey. The rollback is expected to take approximately six hours. Photo credit: NASA/Kim Shiflett

CAPE CANAVERAL, Fla. - At NASA's Kennedy Space Center, the massive crawler-transporter carrying space shuttle Endeavour approaches the launch pad. First motion of Endeavour from the Vehicle Assembly Building was at 11:15 p.m. Sept. 18. The crawler travels on eight tracked tread belts, each containing 57 tread belt “shoes.” Each shoe is 7.5 feet long, 1.5 feet wide and weighs approximately 2,100 pounds. Endeavour completed the 4.2-mile journey to Launch Pad 39B on Sept. 19 at 6:59 a.m. EDT. For the first time since July 2001, two shuttles are on the launch pads at the same time at the center. Endeavour will stand by at pad B in the unlikely event that a rescue mission is necessary during space shuttle Atlantis' upcoming mission to repair NASA's Hubble Space Telescope, targeted to launch Oct. 10. After Endeavour is cleared from its duty as a rescue spacecraft, it will be moved to Launch Pad 39A for the STS-126 mission to the International Space Station. That flight is targeted for launch Nov. 12. Photo credit: NASA/Dimitri Gerondidakis

CAPE CANAVERAL, Fla. -- At NASA's Kennedy Space Center in Florida, a space shuttle era mobile launcher platform, on the left, sits on pedestals outside the Vehicle Assembly Building. To the right is the mobile launcher that will support the space agency's Space Launch System heavy-lift rocket and Orion spacecraft. 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.

Aerial view of the KSC crawler transporters
NASA Technical Reports Server (NTRS)
1998-01-01
In this aerial view the Crawler Transporter Maintenance Building (center) sits between two crawler transporters. The KSC crawlers are the largest tracked vehicles known. Once used to move assembled Apollo/Saturn from the VAB to the launch pad, they are now used for transporting Shuttle vehicles. They move the Mobile Launcher Platform into the Vehicle Assembly Building and then to the Launch Pad with an assembled space vehicle. Maximum speed is 1.6 km (one mile) per hour loaded, about 3.2 km (2 miles) per hour unloaded. Launch Pad to VAB trip time with the Mobile Launch Platform is about 5 hours. The crawler burns 568 liters (150 gallons) of diesel oil per mile. KSC's two crawlers have accumulated 1,243 miles since 1977. Including the Apollo years, the transporters have racked up 2,526 miles, about the same distance as a one-way trip from KSC to Los Angeles by interstate highway or a round trip between KSC and New York City.

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.

In this aerial view the Crawler Transporter Maintenance Building (center) sits between two crawler transporters. The KSC crawlers are the largest tracked vehicles known. Once used to move assembled Apollo/Saturn from the VAB to the launch pad, they are now used for transporting Shuttle vehicles. They move the Mobile Launcher Platform into the Vehicle Assembly Building and then to the Launch Pad with an assembled space vehicle. Maximum speed is 1.6 km (one mile) per hour loaded, about 3.2 km (2 miles) per hour unloaded. Launch Pad to VAB trip time with the Mobile Launch Platform is about 5 hours. The crawler burns 568 liters (150 gallons) of diesel oil per mile. KSC's two crawlers have accumulated 1,243 miles since 1977. Including the Apollo years, the transporters have racked up 2,526 miles, about the same distance as a one-way trip from KSC to Los Angeles by interstate highway or a round trip between KSC and New York City

The Crawler Transporter (CT), designed and built for the Apollo Program in the 1960's and surpassing its initial operational life, has become an integral part of the Space Shuttle Program (SSP). The CT transports the Space Shuttle Vehicle (SSV) stack, atop the Mobile Launch Platform (MLP), from the Vehicle Assembly Building (VAB) to the launch pad. This support structure provides hydraulic jacking, leveling and load equalization for the 12 million pound stack on its 3.5-5.0 mile rollout to the launch pad. Major elements of the SSV, consisting of the orbiter, solid rocket boosters (SRB) and external tank (ET) have required fatigue analyses as part of the mission life certification. Compared to rollout vibration, the SSV sees relatively high vibration loads during launch, ascent, descent and landing phases of the mission. Although preliminary measured SRB vibration levels during rollout were of low amplitude and frequency, the duration of the rollout phase is typically high, from 5-6 hours. As part of an expanded mission life assessment, additional certification effort was initiated to define fatigue load spectra for rollout. This study addresses the CT vibration analyses in support of the rollout fatigue study. Structural models developed for modal and vibration analyses were used to identify unique CT, CT/MLP and CT/MLP/SRB vibration characteristics for comparison to instrumented rollout tests. Whereas the main structural and vibration characteristics of the SSV are well defined, minimum analytical and vibration test data on the Crawler Transporter were available. Unique vibration characteristics of the CT are attributable to the drive mechanism, hydraulic jacking system, structural framing and the CT-to-MLP support pad restraints. Initial tests performed on the CT/MLP/SRB configuration showed reasonable correlation with predicted mode shapes and frequencies.

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. 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. -- Under breaking clouds, Space Shuttle Endeavour, atop the mobile launcher platform and crawler-transporter, crawls its way to Launch Pad 39A for mission STS-99. Named the Shuttle Radar Topography Mission (SRTM), STS-99 involves an international project spearheaded by the National Imagery and Mapping Agency and NASA, with participation of the German Aerospace Center DLR. SRTM will chart a new course, using two antennae and a 200-foot-long section of space station-derived mast protruding from its payload bay, to produce unrivaled 3-D images of the Earth's surface. The result of the Shuttle Radar Topography Mission could be close to 1 trillion measurements of the Earth's topography. Besides contributing to the production of better maps, these measurements could lead to improved water drainage modeling, more realistic flight simulators, better locations for cell phone towers, and enhanced navigation safety. STS-99 is scheduled for launch in January 2000

CAPE CANAVERAL, Fla. -- At NASA's Kennedy Space Center in Florida, Mobile Launcher Platform-2, or MLP-2, is glimpsed across the water as it departs Launch Pad 39A atop a crawler-transporter. A pad on Cape Canaveral Air Force Station is in view in the background. The MLP is being moved to a nearby park site in Launch Complex 39. The historic launch pad was the site from which numerous Apollo and space shuttle missions began and is beginning a new mission as a commercial launch site. NASA signed a property agreement with Space Exploration Technologies Corp., or SpaceX, of Hawthorne, California, on April 14 for use and occupancy of the seaside complex along Florida's central east coast. It will serve as a platform for SpaceX to support their commercial launch activities. For more information on Launch Pad 39A, visit http://www.nasa.gov/centers/kennedy/pdf/167416main_LC39-08.pdf.

Metallurgical Design and Development of NASA Crawler/Transporter Tread Belt Shoe Castings
NASA Technical Reports Server (NTRS)
Parker, Donald S.
2006-01-01
The NASA Crawler/Transporters (CT-1 and CT-2) used to transport the Space Shuffles are one of the largest tracked vehicles in existence today. Two of these machines have been used to move space flight vehicles at Kennedy Space Center since the Apollo missions of the 1960's and relatively few modifications have been made to keep them operational. In September of 2003 during normal Crawler/Transporter operations cracks were observed along the roller pad surfaces of several tread belt shoes. Further examination showed 20 cracked shoes on CT-1 and 40 cracked shoes on CT-2 and a formal failure analysis investigation was undertaken while the cracked shoes were replaced. Six shoes were cross-sectioned with the fracture surfaces exposed and it was determined that the cracks were due to fatigue that initiated on the internal casting web channels at pre-existing casting defects and propagated through thickness both transgranularly and intergranularly between internal shrinkage cavities, porosity, and along austenitic and ferritic grain boundaries. The original shoes were cast during the 1960's using a modified 861330 steel with slightly higher levels of chromium, nickel and molybdenum followed by heat treatment to achieve a minimum tensile strength of 11 Oksi. Subsequent metallurgical analysis of the tread belt shoes after multiple failures showed excessive internal defects, alloy segregation, a nonuniform ferritic/ bainitic/martensitic microstructure, and low average tensile properties indicative of poor casting and poor heat-treatment. As a result, NASA funded an initiative to replace all of the tread belt shoes on both crawler/transporters along with a redesign of the alloy, manufacturing, and heat-treatment to create a homogeneous cast structure with uniform mechanical and metallurgical properties. ME Global, a wholly owned subsidiary of ME Elecmetal based in Minneapolis, MN was selected as manufacturing and design partner to develop the new shoes and this paper describes the research, development, and manufacturing that resulted in the successful delivery of 1044 new Crawler/Transporter tread belt shoes all meeting rigid metallurgical and mechanical design criteria derived from finite element modeling of the stress loads required for safe space shuttle transport.

KENNEDY SPACE CENTER, Fla. -- Scattered clouds cast shadows as Space Shuttle Atlantis crawls back inside the Vehicle Assembly Building high bay 1. After earlier starting its trek to Launch Pad 39B, Atlantis was returned to the VAB due to lightning in the area. To the left of the VAB is the Launch Control Center. The four-story building houses the firing rooms that are used to conduct Space Shuttle launches. Leading away from the VAB, in the foreground, is the crawlerway, the 130-foot-wide road specially constructed to transport the Shuttle, mobile launcher platform and crawler-transporter with a combined weight of about 17 million pounds. Space Shuttle Atlantis is targeted for launch no earlier than July 12 on mission STS-104, the 10th flight to the International Space Station. The payload on the 11-day mission is the Joint Airlock Module, which will allow astronauts and cosmonauts in residence on the Station to perform future spacewalks without the presence of a Space Shuttle. The module, which comprises a crew lock and an equipment lock, will be connected to the starboard (right) side of Node 1 Unity. Atlantis will also carry oxygen and nitrogen storage tanks, vital to operation of the Joint Airlock, on a Spacelab Logistics Double Pallet in the payload bay. The tanks, to be installed on the perimeter of the Joint Module during the missions spacewalks, will support future spacewalk operations and experiments plus augment the resupply system for the Stations Service Module.

Flight mechanics applications for tethers in space: Cooperative Italian-US programs
NASA Technical Reports Server (NTRS)
Bevilacqua, Franco; Merlina, Pietro; Anderson, John L.
1990-01-01
Since the 1974 proposal by Giuseppe Colombo to fly a tethered subsatellite from the Shuttle Orbiter, the creative thinking of many scientists and engineers from Italy and U.S. has generated a broad range of potential tether applications in space. Many of these applications have promise for enabling innovative research and operational activities relating to flight mechanics in earth orbit and at suborbital altitudes. From a flight mechanics standpoint the most interesting of the currently proposed flight demonstrations are: the second Tethered Satellite System experiment which offers both the potential for aerothermodynamics and hypersonics research and for atmospheric science research; the Tethered Initiated Space Recovery System which would enable orbital deboost and recovery of a re-entry vehicle and waste removal from a space station; and the Tether Elevator/Crawler System which would provide a variable microgravity environment and space station center of mass management. The outer atmospheric and orbital flight mechanics characteristics of these proposed tether flight demonstrations are described. The second Tethered Satellite System mission will deploy the tethered satellite earthward and will bring it as low as 130 km from ground and thus into the transition region between the atmosphere (non-ionized) and the partially ionized ionosphere. The atmospheric flight mechanics of the tethered satellite is discussed and simulation results are presented. The Tether Initiated Space Recovery System experiment will demonstrate the ability of a simple tether system to deboost and recover a reentry vehicle. The main feature of this demonstration is the utilization of a Small Expendable Deployment System (SEDS) and the low-tension deployment assumed to separate the reentry vehicle from the Shuttle. This low-tension deployment maneuver is discussed and its criticalities are outlined. The Tether Elevator/Crawler System is a new space element able to move in a controlled way between the ends of a deployed tethered system. A Shuttle test of an Elevator model is planned to demonstrate the unique capability of this element as a microgravity facility and to test the transfer motion control. The basic dynamical features of the Elevator system are presented and a preliminary assessment of the Elevator-induced tether vibrations is discussed.

Operating Deflection Shapes for the Space Shuttle Partial Stack Rollout
NASA Technical Reports Server (NTRS)
Buehrle, Ralph D.; Kappus, Kathy
2005-01-01
In November of 2003 a rollout test was performed to gain a better understanding of the dynamic environment for the Space Shuttle during transportation from the Vehicle Assembly Building to the launch pad. This was part of a study evaluating the methodology for including the rollout dynamic loads in the Space Shuttle fatigue life predictions. The rollout test was conducted with a partial stack consisting of the Crawler Transporter, Mobile Launch Platform, and the Solid Rocket Boosters with an interconnecting crossbeam. Instrumentation included over 100 accelerometers. Data was recorded for steady state speeds, start-ups and stops, and ambient wind excitations with the vehicle at idle. This paper will describe the operating deflection shape analysis performed using the measured acceleration response data. The response data for the steady state speed runs were dominated by harmonics of the forcing frequencies, which were proportional to the vehicle speed. Assuming a broadband excitation for the wind, analyses of the data sets with the vehicle at idle were used to estimate the natural frequencies and corresponding mode shapes. Comparisons of the measured modal properties with numerical predictions are presented.

CAPE CANAVERAL, Fla. -- Space shuttle Discovery awaits its move, called rollback, from Launch Pad 39A to the Vehicle Assembly Building (VAB) at NASA's Kennedy Space Center in Florida. Rollback was scheduled for 12:30 a.m., but was postponed until 10 p.m. so technicians could resolve an issue with a leveling system on the crawler-transporter, which is in front of the shuttle. Once inside the VAB, 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.

2001-01-01
KENNEDY SPACE CENTER, Fla. -- Space Shuttle Atlantis (right) inches its way at 1 mph atop the crawler-transporter back to the Vehicle Assembly Building from Launch Pad 39A (upper left). A panorama view from the top of the VAB shows the proximity of the pad to the Atlantic Ocean (background) plus the 3.4-mile crawlerway leading from the pad to the VAB. The water areas on both sides of the crawlerway are part of the Banana River. In the VAB workers will conduct inspections, make continuity checks and conduct X-ray analysis on the 36 solid rocket booster cables located inside each booster'''s external system tunnel. An extensive evaluation of NASA'''s SRB cable inventory revealed conductor damage in four (of about 200) cables on the shelf. Shuttle managers decided to prove the integrity of the system tunnel cables already on Atlantis before launching. The launch has been rescheduled no earlier than Feb. 6.

KENNEDY SPACE CENTER, FLA. -- A crawler-transporter with mobile launcher platform on top tests the buried portion of the Apollo-era crawlerway leading to the Vehicle Assembly Building (VAB) high bay 2 on the southwest side. The road was restored as part of KSC’s Safe Haven project. High bay 2 provides a third stacking area. The primary goal of the Safe Haven construction project was to strengthen readiness for hurricane season by expanding the VAB’s storage capacity. The new area, in high bay 2, will allow NASA to preassemble stacks and still have room in the VAB to pull a Shuttle back from the pad if severe weather threatens. Potential rollouts of the Space Shuttle to the launch pad from high bay 2 will involve making a turn around the north side of the VAB in contrast to the straight rollouts from high bays 1 and 3, on the east side of the VAB facing the launch pads

CAPE CANAVERAL, Fla. -- Space shuttle Discovery, secured to a crawler-transporter, begins its 3.4-mile trek, known as rollback, from Launch Pad 39A to the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida. Rollback began at 10:48 p.m. 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. -- The interior of NASA's new mobile launcher, or ML, support structure is outfitted with solid steel flooring, lights, air conditioning, electrical boxes and sprinkler piping at NASA's Kennedy Space Center in Florida. 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.

CAPE CANAVERAL, Fla. – At the turn basin at NASA's Kennedy Space Center in Florida, a tug boat keeps the barge in place for the offloading of the girder for the new mobile launcher. The new mobile launcher will be the base for the Ares rockets to launch the Orion crew exploration vehicle and the cargo vehicle. The base is being made lighter than space shuttle mobile launcher platforms so the crawler-transporter can pick up the added load of the 345-foot tower and taller rocket. When the structural portion of the new mobile launcher is complete, umbilicals, access arms, communications equipment and command/control equipment will be installed. Photo credit: NASA/Jack Pfaller

CAPE CANAVERAL, Fla. -- Space shuttle Discovery awaits its move, called rollback, from Launch Pad 39A to the Vehicle Assembly Building (VAB) at NASA's Kennedy Space Center in Florida. Rollback was scheduled for 12:30 a.m., but was postponed until 10 p.m. so technicians could resolve an issue with a leveling system on the crawler-transporter, which is to the left of the shuttle. Once inside the VAB, 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.

The cracked cleat on the crawler-transporter track that stalled the rollout of Space Shuttle Endeavour lies on the ground near Launch Pad 39B. The cracked cleat forced the reverse of the rollout back outside the pad gate so the cleat could be repaired on flat ground before moving up the incline to the top of the pad. Endeavour is scheduled to be launched Nov. 30 at 10:01 p.m. EST on mission STS-97, the sixth construction flight to the International Space Station. Its payload includes the P6 Integrated Truss Structure and a photovoltaic (PV) module, with giant solar arrays that will provide power to the Station. The mission includes two spacewalks to complete the solar array connections

Swenson, Frank R.
1987-01-01
One of the needs of the experimenters on the space station is access to steady and controlled-variation microgravity environments. A method of providing these environments is to place the experiment on a tether attached to the space station. This provides a high degree of isolation from structural oscillations and vibrations. Crawlers can move these experiments along the tethers to preferred locations, much like an elevator. This report describes the motion control laws developed for these crawlers and the testing of laboratory models of these tether elevator crawlers.

CAPE CANAVERAL, Fla. – Sitting on top of the mobile launcher platform, space shuttle Discovery arrives on top of Launch Pad 39A at NASA's Kennedy Space Center in Florida. 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 foreground next to Discovery's main engines is one of the two tail masts, which provide several umbilical connections to the orbiter, including a liquid-oxygen line through one and a liquid-hydrogen line through another. 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

KENNEDY SPACE CENTER, FLA. Workers maneuver the giant sprocket (left) and attached gear (right) into position on the Crawler- Transporter. The drive sprocket turns the belt on the CT. The sprocket is mated to the gear that attaches to the drive motor. The CT travels on eight tracked tread belts, each containing 57 tread belt shoes, for a combined weight of 957,600 pounds. The CT carries the Space Shuttle atop its Mobile Launcher Platform, adding another 12 million pounds, from the Vehicle Assembly Building to the launch pad. NASA and United Space Alliance (USA) CT system engineers and USA technicians are repairing the sprockets and rollers on each belt before new shoes are installed. Replacement of the sprockets, gears and shoes is part of the most extensive maintenance work performed on the CT in its history.

Shuttle Program Loads Integration: Going From Concept to Operations and Staying Successful
NASA Technical Reports Server (NTRS)
Bernstein, Karen; James, George; Mackey, alden; Murphy, Neil C.; Brolliar, Steve
2011-01-01
From the beginning of the Shuttle Program to its end, integrated loads and dynamics analyses and tests have been critical in shaping the vehicle design and operational decisions for NASA and its customers. Starting with scaled models and simple mathematical simulations of the structural dynamics, engineers defined the required structural stiffness and predicted the limit loads for each element of the system. Early structural tests provided reasonable confidence that the models and predictions were good. The first launch of the Space Shuttle brought surprises, though, when the ignition overpressure event caused a forward fuel tank support strut to buckle, among several unexpected effects. The launch pad and other ground equipment became an integral part of the system integration, especially where the acoustic and pressure environments of ignition and lift-off were concerned. Following the Challenger accident, operating limits were changed in response to new understandings of how the integrated system performed. Controlling loads while maximizing performance was a key tenet of the Performance Enhancement design process, which enabled construction of the International Space Station. During the return to flight after the Columbia accident, engineers grew to understand that loads during the roll maneuver were also important to the vehicle s structural margin and life. At this point the crawler transport from the Vehicle Assembly Building to the launch pad also became a part of the integrated loads analysis. Even in the last years of the Space Shuttle Program, new data still provided interesting insights into this complicated and fascinating spaceship. This paper will present some examples of the important findings by the team of specialists that supported the Integrated Loads and Dynamics Panel for the Space Shuttle Program.

KENNEDY SPACE CENTER, FLA. - A Kennedy Space Center technician inspects the shoes on one of eight tracks of a crawler-transporter (CT). The CT is moving Mobile Launcher Platform (MLP) number 3 with a set of twin solid rocket boosters bolted on top to the intersection in the crawlerway in support of the second engineering analysis vibration test on the crawler and MLP. The crawler is moving at various speeds up to 1 mph in an effort to achieve vibration data gathering goals as it leaves the VAB, travels toward Launch Pad 39A and then returns. The boosters are braced at the top for stability. The primary purpose of these rollout tests is to gather data to develop future maintenance requirements on the transport equipment and the flight hardware. Various parts of the MLP and crawler transporter have been instrumented with vibration data collection equipment.

CAPE CANAVERAL, Fla. – Space shuttle Discovery is silhouetted against the dawn sky as it rolls out to Launch Pad 39A at NASA's Kennedy Space Center in Florida. First motion out of the Vehicle Assembly Building was at 2:07 a.m. EDT Aug. 4. Rollout was delayed approximately 2 hours due to lightning in the area. The 3.4-mile journey was slower than usual as technicians stopped several times to clear mud from the crawler's treads and bearings caused by the waterlogged crawlerway. 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.

ESTIMATION OF THE SPACE SHUTTLE ROLLOUT FORCING FUNCTION

James, George H., III; Carne, Thomas; Elliott, Kenny; Wilson, Bruce
2005-01-01
The Space Shuttle Vehicle is assembled in the Vertical Assembly Building (VAB) at Kennedy Space Flight Center in Florida. The Vehicle is stacked on a Mobile Launch Platform (MLP) that weighs eight million pounds. A Crawler Transporter (CT) then carries the MLP and the stacked vehicle (12 million pounds total weight) to the launch complex located 5 miles away. This operation is performed at 0.9 mph resulting in a 4.5-hour transport. A recent test was performed to monitor the dynamic environment that was produced during rollout. It was found that the rollout is a harmonic-rich dynamic environment that was previously not understood. This paper will describe work that has been performed to estimate the forcing function that is produced in the transportation process. The rollout analysis team has determined that there are two families of harmonics of the drive train, which excite the system as a function of CT speed. There are also excitation sources, which are random or narrow-band in frequency and are not a function of CT speed. This presentation will discuss the application of the Sum of Weighted Accelerations Technique (SWAT) to further refine this understanding by estimating the forces and moments at the center-of-mass.

CAPE CANAVERAL, Fla. -- The moon shines brightly over space shuttle Discovery following a total lunar eclipse as the spacecraft waits to roll back from Launch Pad 39A to the Vehicle Assembly Building (VAB) at NASA's Kennedy Space Center in Florida. The move was scheduled for 12:30 a.m., but was postponed until 10 p.m. so technicians could resolve an issue with a leveling system on the crawler-transporter. Once inside the VAB, 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 is no earlier than Feb. 3, 2011. For more information on STS-133, visit www.nasa.gov/mission_pages/shuttle/shuttlemissions/sts133/. Photo credit: NASA/Kim Shiflett

CAPE CANAVERAL, Fla. -- The moon shines brightly over space shuttle Discovery following a total lunar eclipse as the spacecraft waits to roll back from Launch Pad 39A to the Vehicle Assembly Building (VAB) at NASA's Kennedy Space Center in Florida. The move was scheduled for 12:30 a.m., but was postponed until 10 p.m. so technicians could resolve an issue with a leveling system on the crawler-transporter. Once inside the VAB, 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.

CAPE CANAVERAL, Fla. – At NASA's Kennedy Space Center in Florida, the tower on a new mobile launcher, or ML, for the Constellation Program grows as the fourth section is lowered into position. The tower will be approximately 345 feet tall when completed and have multiple platforms for personnel access. The ML is being built at the mobile launcher park site area north of Kennedy's Vehicle Assembly Building. The launcher will provide a base to launch the Ares I, designed to transport the Orion crew exploration vehicle, its crew and cargo to low Earth orbit. The base is being made lighter than space shuttle mobile launcher platforms so the crawler-transporter can pick up the heavier load of the tower and taller rocket.

NASA Technical Reports Server (NTRS)
1999-01-01
Space Shuttle Discovery makes the turn toward Launch Pad 39B on its 4.2-mile (6.8 kilometer) trek 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-Frangois Clervoy of France, both with the European Space Agency.

CAPE CANAVERAL, Fla. – Cast in shadow by the external fuel tank blocking the morning sun, space shuttle Discovery makes its way to Launch Pad 39A at NASA's Kennedy Space Center in Florida. The 3.4-mile journey was slower than usual 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 Vehicle Assembly Building was at 2:07 a.m. EDT Aug. 4. Rollout was delayed approximately 2 hours due to lightning in the area. 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/Dimitri Gerondidakis

The crack in the crawler-transporter cleat that delayed rollout of Space Shuttle Endeavour can be seen as a white dotted line on the top-center and running down the right side. The cleat rests on the ground near Launch Pad 39B. The cracked cleat forced the reverse of the rollout back outside the pad gate so the cleat could be replaced on flat ground before moving up the incline to the top of the pad. Endeavour is scheduled to be launched Nov. 30 at 10:01 p.m. EST on mission STS-97, the sixth construction flight to the International Space Station. Its payload includes the P6 Integrated Truss Structure and a photovoltaic (PV) module, with giant solar arrays that will provide power to the Station.

Pipe crawler with extendable legs
Zollinger, William T.
1992-01-01
A pipe crawler for moving through a pipe in inchworm fashion having front and rear leg assemblies separated by air cylinders to increase and decrease the spacing between assemblies. Each leg of the four legs of an assembly is moved between a wall-engaging, extended position and a retracted position by a separate air cylinder. The air cylinders of the leg assemblies are preferably arranged in pairs of oppositely directed cylinders with no pair lying in the same axial plane as another pair. Therefore, the cylinders can be as long a leg assembly is wide and the crawler can crawl through sections of pipes where the diameter is twice that of other sections. The crawler carries a valving system, a manifold to distribute air supplied by a single umbilical air hose to the various air cylinders in a sequence controlled electrically by a controller. The crawler also utilizes a rolling mechanism, casters in this case, to reduce friction between the crawler and pipe wall thereby further extending the range of the pipe crawler.

Each leg of the four legs of an assembly is moved between a wall-engaging, extended position and a retracted position by a separate air cylinder. The air cylinders of the leg assemblies are preferably arranged in pairs of oppositely directed cylinders with no pair lying in the same axial plane as another pair. Therefore, the cylinders can be as long as a leg assembly is wide and the crawler can crawl through sections of pipes where the diameter is twice that of other sections. The crawler carries a valving system, a manifold to distribute air supplied by a single umbilical air hose to the various air cylinders in a sequence controlled electrically by a controller. The crawler also utilizes a rolling mechanism, casters in this case, to reduce friction between the crawler and pipe wall thereby further extending the range of the pipe crawler. 8 figs.

CAPE CANAVERAL, Fla. – At NASA's Kennedy Space Center in Florida, a crane lowers the third section of the tower for a new mobile launcher, or ML, for the Constellation Program into place atop the growing structure. Installation of the first section was on Sept. 24, and the second, on Oct. 15. The tower will have multiple platforms for personnel access and be approximately 345 feet tall. The launcher is being built at the mobile launcher park site area located north of Kennedy's Vehicle Assembly Building to support the Ares I rocket. The ML will provide a base to launch the Ares I, designed to transport the Orion crew exploration vehicle, its crew and cargo to low Earth orbit. The base is being made lighter than space shuttle mobile launcher platforms so the crawler-transporter can pick up the heavier load of the tower and taller rocket.

Under the goals of the Vision for Space Exploration, Ares I is a chief component of the cost-effective space transportation infrastructure being developed by NASA's Constellation Program. This transportation system will safely and reliably carry human explorers back to the moon, and then onward to Mars and other destinations in the solar system. Launch Pad 39B of the Kennedy Space Flight Center (KSC), currently used for Space Shuttle launches, will be revised to host the Ares launch vehicles. The fixed and rotating service structures standing at the pad will be dismantled sometime after the Ares I-X test flight. A new launch tower for Ares I will be built onto a new mobile launch platform. The gantry for the shuttle doesn't reach much higher than the top of the four segments of the solid rocket booster. Pad access above the current shuttle launch pad structure will not be required for Ares I-X because the stages above the solid rocket booster are inert. For the test scheduled in 2012 or for the crewed flights, workers and astronauts will need access to the highest levels of the rocket and capsule. When the Ares I rocket rolls out to the launch pad on the back of the same crawler-transporters used now, its launch gantry will be with it. The mobile launchers will nestle under three lightning protection towers to be erected around the pad area. Ares time at the launch pad will be significantly less than the three weeks or more the shuttle requires. This “clean pad” approach minimizes equipment and servicing at the launch pad. It is the same plan NASA used with the Saturn V rockets and industry employs it with more modern launchers. The launch pad will also get a new emergency escape system for astronauts, one that looks very much like a roller coaster. Cars riding on a rail will replace the familiar baskets hanging from steel cables. This artist's concept illustrates the Ares I on launch pad 39B.

Space Shuttle Discovery, atop the mobile launcher platform and crawler transporter, nears the top of Launch Pad 39B after a 4.2-mile crawl from the Vehicle Assembly Building. At left are the Rotating Service Structure and the Fixed Service Structure, which will enable final preparations of the orbiter, external tank and solid rocket boosters 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-Frangois Clervoy of France, both with the European Space Agency.

CAPE CANAVERAL, Fla. – 2008 Daytona 500 winner Ryan Newman (left) and Daytona International Speedway President Robin Braig talk to the media gathered on the crawlerway on Launch Pad 39A at NASA's Kennedy Space Center. The Daytona International Speedway show car, shown here, is in sharp contrast to the crawler-transporter that usually travels the special road to the pad. Newman is visiting Kennedy in honor of NASA's 50th anniversary and the 50th running of NASCAR's Daytona 500 in February. NASA presented Newman two green racing flags that were flown last February aboard space shuttle Atlantis' STS-122 mission to the International Space Station. One flag was given to Newman, the second was presented to Daytona 500 Experience General Manager Kim Isemann. A third flag that was flown will be kept by NASA for public display. The connection between NASA and Daytona's International Speedway extends beyond their close proximity to one another. During recent years, technology developed for the space program has found many uses on Earth, including helping NASCAR drivers stay safe and increase performance. Photo credit: NASA/Kim Shiflett

Space Shuttle Transportation (Roll-Out) Loads Diagnostics
NASA Technical Reports Server (NTRS)
Elliott, Kenny B.; Buehrle, Ralph D.; James, George H.; Richart, Jene A.
2005-01-01
The Space Transportation System (STS) consists of three primary components; an Orbiter Vehicle, an External Fuel Tank, and two Solid Rocket Boosters. The Orbiter Vehicle and Solid Rocket Boosters are reusable components, and as such, they are susceptible to durability issues. Recently, the fatigue load spectra for these components have been updated to include load histories acquired during the rollout phase of the STS processing for flight. Using traditional program life assessment techniques, the incorporation of these "rollout" loads produced unacceptable life estimates for certain Orbiter structural members. As a result, the Space Shuttle System Engineering and Integration Office has initiated a program to re-assess the method used for developing the "rollout" loads and performing the life assessments. In the fall of 2003 a set of tests were preformed to provide information to either validate existing load spectra estimation techniques or generate new load spectra estimation methods. Acceleration and strain data were collected from two rollouts of a partial-stack configuration of the Space Shuttle. The partial stack configuration consists of two Solid Rocket Boosters tied together at the upper External Tank attachment locations mounted on the Mobile Launch Platform carried by a Crawler Transporter (CT). In the current analysis, the data collected from this test is examined for consistency in speed, surface condition effects, and the characterization of the forcing function. It is observed that the speed of the CT is relatively stable. The dynamic response acceleration of the partial-stack is slightly sensitive to the surface condition of the road used for transport, and the dynamic response acceleration of the partial-stack generally increases as the transport speed increases. However, the speed sensitivity is dependent on the measurement location. Finally, the character of the forcing function is narrow-banded with the primary drivers being harmonics of two CT speed dependent excitations. One source is an excitation due to the CT treads striking the road surface, and the second is unknown.

CAPE CANAVERAL, Fla. – Members of the media stretch across the crawlerway on Launch Pad 39A at NASA's Kennedy Space Center to interview 2008 Daytona 500 winner Ryan Newman (center right). At left is Daytona International Speedway President Robin Braig. The Daytona International Speedway show car, shown here, is in sharp contrast to the crawler-transporter that usually travels the special road to the pad at a maximum speed of 2 mph. Newman is visiting Kennedy in honor of NASA's 50th anniversary and the 50th running of NASCAR's Daytona 500 in February. NASA presented Newman two green racing flags that were flown last February aboard space shuttle Atlantis' STS-122 mission to the International Space Station. One flag was given to Newman, the second was presented to Daytona 500 Experience General Manager Kim Isemann. A third flag that was flown will be kept by NASA for public display. The connection between NASA and Daytona's International Speedway extends beyond their close proximity to one another. During recent years, technology developed for the space program has found many uses on Earth, including helping NASCAR drivers stay safe and increase performance. Photo credit: NASA/Kim Shiflett

Development of a High Level Waste Tank Inspection System
DOE Office of Scientific and Technical Information (OSTI.GOV)
Appel, D.K.; Loibl, M.W.; Meese, D.C.
1995-03-21
The Westinghouse Savannah River Technology Center was requested by it`s sister site, West Valley Nuclear Service (WVNS), to develop a remote inspection system to gather wall thickness readings of their High Level Waste Tanks. WVNS management chose to take a proactive approach to gain current information on two tanks t hat had been in service since the early 70`s. The tanks contain high level waste, are buried underground, and have only two access ports to an annular space between the tank and the secondary concrete vault. A specialized remote system was proposed to provide both a visual surveillance and ultrasonicmore » thickness measurements of the tank walls. A magnetic wheeled crawler was the basis for the remote delivery system integrated with an off-the-shelf Ultrasonic Data Acquisition System. A development program was initiated for Savannah River Technology Center (SRTC) to design, fabricate, and test a remote system based on the Crawler. The system was completed and involved three crawlers to perform the needed tasks, an Ultrasonic Crawler, a Camera Crawler, and a Surface Prep Crawler. The crawlers were computer controlled so that their operation could be done remotely and their position on the wall could be tracked. The Ultrasonic Crawler controls were interfaced with ABB Amdata`s I-PC, Ultrasonic Data Acquisition System so that thickness mapping of the wall could be obtained. A second system was requested by Westinghouse Savannah River Company (WSRC), to perform just ultrasonic mapping on their similar Waste Storage Tanks; however, the system needed to be interfaced with the P-scan Ultrasonic Data Acquisition System. Both remote inspection systems were completed 9/94. Qualifications tests were conducted by WVNS prior to implementation on the actual tank and tank development was achieved 10/94. The second inspection system was deployed at WSRC 11/94 with success, and the system is now in continuous service inspecting the remaining high level waste tanks at WSRC.« less

This document describes two conceptual designs for a Tank Remote Repair System to perform leak site repairs of double shell waste tank walls (Types I, II, III, and IIIA) from the annulus space. The first concept uses a magnetic wall crawler and an epoxy patch system and the second concept uses a magnetic wall crawler and a magnetic patch system. The recommended concept uses the magnetic patch system, since it is simpler to deliver, easier to apply, and has a higher probability of stopping an active leak.

In this aerial view, the tail of the orbiter Discovery can be seen as it begins rolling out of the Orbiter Processing Facility (OPF) bay 1 (center left of photo). Behind it is the tow-way, which leads from the Shuttle Landing Facility past the OPF. In the foreground is the new road under construction as part of the Safe Haven project. And at right is the one of two crawlers used to move the Shuttles to the launch pad. Discovery is moving to the Vehicle Assembly Building for stacking with an external tank and solid rocket boosters before its launch on mission STS-103. The launch date is currently under review for early December. STS-103, the third Hubble Space Telescope servicing 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 replacing a Fine Guidance Sensor and an older computer with a new enhanced model, an older data tape recorder with a solid-state digital recorder, a failed spare transmitter with a new one, and 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.

Crawler Transporter Steering and Jel Systems
NASA Technical Reports Server (NTRS)
Davis, V. L.
1975-01-01
The transporter weighing 2.8 million kilograms (6.3 million pounds) was used to lift a 5.7-million-kilogram (12.6-million-pound) combination of mobile launcher and space vehicle, transfer this load approximately 5.6 kilometers (3.5 miles) from its point of assembly, negotiate curves of 152-meter (500-foot) mean radius, climb a 5-percent grade while maintaining the 122-meter (400-foot) structure in a vertical position within 10 minutes of arc, and smoothly position this huge structure to within plus or minus 5.1 centimeters (plus or minus 2 inches) on support pedestals at the launch pad. The crawler-transporter is described in detail.

KENNEDY SPACE CENTER, FLA. -- A crane operator (center) talks with technicians (right) standing next to one of the jacking, equalization and leveling (JEL) cylinders from Crawler-Transporter No. 2. During inspections, technicians removed two of the 16 JEL cylinders on the vehicle to gain access to the bearings for routine maintenance and found three of the four bearings had cracks. Of the three bearings, two had extensive damage. Further eddy current inspections indicate that cracks are present on 15 of the bearings. There are 16 cylinders and 32 bearings per crawler. Although no cause for the cracks is known at this time, engineers are currently evaluating the situation to determine the most appropriate solution.

Device for inspecting vessel surfaces
Appel, D. Keith
1995-01-01
A portable, remotely-controlled inspection crawler for use along the walls of tanks, vessels, piping and the like. The crawler can be configured to use a vacuum chamber for supporting itself on the inspected surface by suction or a plurality of magnetic wheels for moving the crawler along the inspected surface. The crawler is adapted to be equipped with an ultrasonic probe for mapping the structural integrity or other characteristics of the surface being inspected. Navigation of the crawler is achieved by triangulation techniques between a signal transmitter on the crawler and a pair of microphones attached to a fixed, remote location, such as the crawler's deployment unit. The necessary communications are established between the crawler and computers external to the inspection environment for position control and storage and/or monitoring of data acquisition.

Uses for lunar crawler transporters
NASA Astrophysics Data System (ADS)
Kaden, Richard A.
This article discusses state-of-the-art crawler transporters and expresses the need for additional research and development for lunar crawlers. The thrust of the paper illustrates how the basic crawler technology has progressed to a point where extremely large modules can be shop fabricated and move to some distant location at a considerable savings. Also, extremely heavy loads may be lifted by large crawler cranes and placed in designed locations. The Transi-Lift Crawler crane with its traveling counterweight is an attractive concept for lunar construction.

KENNEDY SPACE CENTER, Fla. -- In the cloud-dimmed light of early morning, Space Shuttle Endeavour sits in place at Launch Pad 39A , atop the mobile launcher platform and crawler transporter, after rollout from the Vehicle Assembly Building. At its left are the Rotating Service Structure and Fixed Service Structure with the orbiter access arm extended. The access arm swings out to the orbiter crew compartment hatch to allow personnel to enter the crew compartment. At its outer end is the white room, an environmental chamber, that mates with the orbiter. While at the pad, the orbiter, external tank and solid rocket boosters will undergo final preparations for the STS-88 launch targeted for Dec. 3, 1998. Mission STS-88 is the first U.S. flight for the assembly of the International Space Station and will carry the Unity connecting module. While on orbit, the flight crew will deploy Unity from the payload bay and connect it to the Russian-built Zarya control module which will be in orbit at that time. Unity will be the main connecting point for later U.S. station modules and components. More than 40 launches are planned over five years involving the resources and expertise of 16 cooperating nations. Comprising the STS-88 crew are Commander Robert D. Cabana, Pilot Frederick W. "Rick" Sturckow, Mission Specialists Nancy J. Currie, Jerry L. Ross, James H. Newman and Russian cosmonaut Sergei Konstantinovich Krikalev. Ross and Newman will make three spacewalks to connect power, data and utility lines and install exterior equipment

1999-11-13
KENNEDY SPACE CENTER, FLA. -- Towering atop the mobile launcher platform and crawler transporter, Space Shuttle Discovery negotiates a turn in the crawlerway on its trek from the Vehicle Assembly Building to Launch Pad 39B. 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. The STS-103 crew members 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.), and Mission Specialist Claude Nicollier of Switzerland, and Mission Specialist Jean-François Clervoy of France, both with the European Space Agency
