Here was the complete 3-part package: The Crawler, on bottom, was two stories. The Transporter was on top of the Crawler and was three more stories. On the top of the Transporter the Shuttle was attached. This photo is of the Atlantis on the Crawlerway.


NASA has two Crawlers. They are usually parked at the yard adjacent to the Orbiter Process Facilities and across the street from the VAB. Sometimes one is parked at a yard on the roadway to Pads 39-A and 39-B where those visiting the Visitor's Center can see them on their way to a viewing stand.

The Crawler/Transporter is a behemoth. This is the carrier which took the fully assembled Shuttle with its fuel tanks attached to the launch pad.

Consider these basics —

Weight: 2,721 metric tons (6 million pounds)
Length: 40 meters (131 ft) wide, 35 meters (114ft) long
Miles: 2,526 miles (1,243 miles since 1977)

The Crawler has her own special road known as the Crawlerway.

She only runs on this specially built dual highway of Mississippi rock between the VAB, her storaage yards and Pads 39-A and 39-B. Each time she heads out for a cruise on her highway, she so completely flattens the rocks on the roadbed that the rocks must be “fluffed” after each trip, and replaced, on average after she’s been over them ten times.

Each cleats on each of her eight tracks weighs one ton.

Getting a Shuttle to the Launching Pad was a two step process.

Terry Berman is manager of Crawler Operations. Previously he was in charge of Pad 39-B which has been torn down and will be re-purposed for still-to-be-determined later space missions.

First the Shuttle was towed to the Vehicle Assembly building from its hangar (known as an OFP — or Orbiting Processing Facility). In the VAB the shuttle was harnessed in the Transit Aisle and then hoisted 500 feet to the top of the VAB, and then moved laterally into one of two “High Bays”. The shuttle was then lowered and secured to the Crawler/Transporter.

The Crawler and Transporter are two separate pieces. The system, in use since the Apollo Moon program in the 1960s, will survive to serve the next generation of space vehicle. The vehicle with its tracks is the base. The Transporter is secured on top of the Crawler, and then a vehicle is secured to the Transporter.

Once a vehicle is safely secured, the Transporter sets out for the launch pad at eight-tenths of a mile per hour. Unloaded it can do about 2 mph.

The Crawler tilts.

As the Crawler climbs the final yards to the launching pad, it climbs a hill. As it climbs the Crawler has internal devices which tilt the Transporter keeping the Shuttle level (otherwise there is a risk that it would fall off). Once the Crawler has delivered the Transporter and the vehicle to the launch pad, it drives away. The vehicle is then launched a few weeks later.
.

Entry to the Crawler yard is through a tightly controlled fence, inside a tightly controlled area. The last use of a Crawler was to move a launching device built for the now-cancelled Constellation program to and from Pad 39-B in November 2011. The Crawler, while they will be carefully preserved and maintained, may not be used again until 2017. NASA appears to have little, if any, support from President Obama and his administration.


.

The control room. Surprisingly the Crawler has only one floor and inside it is almost all engines. It can be driven from either end in small cabs where drivers switch off every two hours. Systems are monitored here when the Crawler is moving. A team also walks with the Crawler on the ground and visually observes it when the Crawler is in motion.


.

The inside of the Crawler which is accessed by climbing a rickety stairway is almost all engines except for the control room. The Shuttle is not driven from the control room, but systems are monitored there.


.

A catwalk circles the entire second floor of the Crawler. There is no first floor, and the third floor is a flat surface where the Transporter is attached. This photograph is from on end of the Crawler looking back toward the other end.,


.

Cockpit of the Crawler. There are two cockpits, one on opposite ends allowing the Crawling to be driven in both directions. It takes about 18 months of training to become a driver. When driving, drivers generally drive about two hours, then switch off. The drive from the VAB to the launch pads generally took 6+ hours at less than 1 mph.


.

Portapottie. A temporary bathroom is discretely tucked on one end of the Crawler. This is the only restroom on the Crawler.


.

The Crawler's eight tracks are massive. Each clete, specially made by only one factory, weighs 2,000 pounds and yes, they do wear out and have to be replaced.


.

This is the second of the two cockpits on the opposite end of the Crawler from the cockpit picture above. The cockpits and the driving controls (just below) appear identical.


.

Have a seat and let's go. There are no speed limits on the Crawlerway, but then again top speed of the Crawler is less than 2 mph. The driver has no seatbelt.


.

The cockpit is small, but has room comfortably for the driver and a second person. This photograph was taken from the middle of the Crawler on the "second' floor. There is no first or third floor.


.

The Crawler stands tall enough that autos and trucks can easily drive underneath. Fully loaded with a transporter, the Crawler stands five stories high. When photographing the Crawler and Transporter with a shuttle secured to it, the media was taken to the fifth floor of the VAB where they were level with the top of the Transporter and where their photographs appears to be at ground level, but were actually more than 50' or five stories above the ground..


.

Pete Crow, who is 6'0", stands under exactly in the center underneath the Crawler to get perspective to the Crawler's massive size.


.

This photograph is taken standing on the ground and looking up at the Crawler.


.

This is the exact 180-degree view from the photograph just above.


.

Carol Anne Swagler stands on one of the two pebble covered tracks which serve as the Crawler's highway to the two launch pads. Ms. Swagler, a veteran newspaper woman, was working as a photographer for an Oklahoma newsapaper, The Grove Sun Daily. In the waning days of the shuttle program, Ms. Swagler was frequently accredited to photograph the shuttle and other NASA launches at the Cape. The Grove Sun Daily, unusual for a small daily, sent reporters and photographers to cover the space program frequently, all the way back to the Apollo 17 moon launch in 1972; its community had a NASA sub-contractor. In the background over Ms. Swagler's shoulder is the Vehicle Assembly Building. The Crawler and shuttle are heading toward Ms. Swagler -- she had walked on ahead. If she had not moved -- which she did -- the Crawler would have flattened her and there would have been no more trips to the Cape for Ms. Swagler.

On Monday the media center was empty and the KSC media staff said they were glad to see the media back. It has been so lonely without us. Maybe, maybe not. With only an exception or two the NASA KSC pr staff is terrific to deal with.

INDEX to MEDIA EVENTS
Launch-minus-Four-Days L-4, Monday November 21, 2011

FIRST ===
11 am RADIOLOGICAL CONTROL CENTER (RADCC)

Safety procedures for the Mars Science Laboratory’s (MSL) Multi-Mission Radioisotope Thermoelectric Generator (MMRTG)

SECOND ===
1 pm WHAT DO WE KNOW ABOUT MARS?

Michael Meyer, lead scientist Mars Exploration Program
John Grotzinger, project scientist, MSL, California Institute of Technology
Bethany Ehlmann, scientist, Jet Propulsion Laboratory (JPL), assistant professor, California Institute of Technology

Example of a wheel from the MSL (MSL has six) in the Media Center at KSC. The rover was designed in Pasadena, CA, at the Jet Propulsion Laboratory. JPL was so proud they put their name on the tire (like Firestone) and were told by a peevish NASA to take their name off. They did, but take a look at those odd holes in the tire. Those holes are Morse Code letters J, P and L.

THIRD ===
2:30 pm 21ST CENTURY GROUND SYSTEMS TOUR

visit: Launch Equipment Test Facility
visit: Operations and Checkout Building for Orion Manned Space Capsule
visit: Multi-Payload Processing Facility
visit: Canister Rotation Facility

Five Days to Go: The Countdown begins
The launch of the Mars Science Laboratory, a two-ton rover packed with the ability to conduct scientific experiments is five days away. Thanksgiving is Thursday, so the launch clock will go from L-2 on Wednesday, skip Thursday, and L-1 will be on Friday.

NASA has packed the week with briefings for the media and, when the Tweeters are allowed in on Friday, there will be a bunch more briefings for them.

Sunday night, November 20, 2011
Months ago I requested credentials for the launch, uncertain that I would be in Florida. Most of the fall I have been in Los Angeles or Austin at Red Studios, at the American Film Market and at the Austin Film Festival.

I remembered that the launch was going to be about Thanksgiving. Thanksgiving is next Thursday. I log on to the NASA Media site and download the schedule.

Uh-oh, Briefings begin in the morning.

I ponder this. Carol Anne, who photographs for me, is in Virginia. She will not return until Monday night and I will need to pick her up at the airport in Orlando. I’ve lost her arrival time, but can figure it out. The NASA briefings begin at 11 Monday morning and go most of the day. I need to build in an extra hour to pick up my credentials, a task complicated by NASA sometimes credentialing at the badging office on State Highway 405, and at other times on State Road 3.

Normally a quick call to the NASA Press office tells me where to go. But during the summer my iPhone brunched down my telephone book.

I take a deep breath and bet on the State Road 405 badging office and, bet correctly. But then the badging officer demands that I show her my “Credential Letter” in addition to my passport and my driver’s license. No one has ever asked me to print out the email confirming my accreditation before.

We stare. Isn’t name in the computer? Yes. So am I not accredited? Silent staring. I have not budgeted what will not cost at least another hour, still I have to give up …

“I will go find somewhere and print it out,” I finally say giving up, smiling my aging choir boy smile.

With that she hands me my badge. “Next time,” she says, “have that letter.”

. . . . .

On Monday morning the Tweet tent was ready for the Tweeters, loaded with high tech equipment. But wait -- the Tweeters don't come until Friday because the launch has been pushed back a day. So will all of this expensive stuff sit out here under the sun for most of the week? Apparently so -- a dour guard tells me he has settled in to babysit everything 24/7 until the Tweeters show up.

The Media Center, 10:30 am

I sign up for all of the tours for the day and am almost the only one on the list. I banter with Jennifer and Laurel and re-punch the media numbers into my iPhone. The media center is empty.

Will I need to request work space? No. Only 178 media are accredited and half or more will not show up. This means that this time Tweeters, at 150, will almost match the number of media.

I have a list of access requests and discuss them. I am told with a single exception fulfilling them should be no problem. I’m given the contacts and the email addresses. Will it really be this easy now that 90-percent of the media is gone and we’re back to un-manned missions where human life is no longer at stake?

It sure looks like it.

11 am The KSC Radiological Control Center (RADCC)
The Mars Science Laboratory carries is powered by uranium. If that canister of uranium is ruptured on launch, it could contaminate a wide area around the launch site.

NASA this morning wants the media to see the precautions they are taking, and to see an example of the canister itself. First we visit the Radiological Control Center which monitors more than one hundred radiation devices in a huge swatch of central Florida. Then we are tasken into a separate control room which, in the event of an accident, will be responsible for informing the media.

It’s very convincing. These guys cannot afford an accident, especially one that radiates central Florida. It ain’t gonna happen (and on Saturday, it doesn’t).
.

Lots of stuff is in the same building as the Radiological Control Center, including a dorm of the third floor for the astronauts.


.

The media was welcomed and greeted in the foyer before going upstairs to the control rooms. NASA is very sensitive that any danger issues be addressed and answered.


.

Example of one of several different radiological monitoring devices NASA placed in large numbers over a huge swatch of central Florida. These devices are sending data constantly and are being monitored in the Radiological Control Center constantly during and following launch.


.

Many of the facilities at Kennedy Space Center are now being re-purposed with the end of the Space Shuttle program. Feeling tension and need a massage? The massage therapist has moved. This sign is prominent in the foyer of the building where the Radiological Control Center is located.


.

If something bad happens during launch (and it never has) these guys would know first. The remote monitoring devices are reporting constantly to these monitors.


.

The Cowbell. This is a busy and not always quiet room. If something bad happens or if the attention of everyone in the room is required, CLANG, CLANG, CLANG the cowbell is used. The bell was demonstrated for the unruly media and is quite convincing. My ears are still ringing. Moo.


.

Department of Energy official explains how the MSL is powered, and why the uranium in the MSL can be launched safely. Later in the week he told me that the MSL will have power to operate as long as 14 years, long after the MSL is expected to be operations on the surface of Mars.


.

MSL's power source. Small but powerful and so completely sealed that all efforts to smash the capsule and expose the uranium failed. They figured out how to seal it up; they never managed to bust it open. Nonetheless, a large operation stands by in the Radiological Control Center should the capsule rupture and scatter uranium.


.

This is the press room where, should there be a radiological danger after launch of the MSL, the press and public will be informed. Big operation. Never been needed.


.

Pride in NASA, and pride in the accomplishments of the American space program are everywhere, even as these offices empty out and people lose their jobs. The shuttle is gone and the future of the United States in space, while not tenuous, is not as robust as it once was when we were launching humans into space.

.
.

Michael Meyer (second from left), Bethany Ehlmann (second from right) and John Grotzinger (far right) spent an hour in early afternoon discussing "What do we know about Mars?" The answer is, a lot, including that water appears to be trapped there and while it is not conclusive that life ever existed on Mars, there's growing suspicion that it may have, and may still. Meyer is the lead scientist on the Mars Exploration Program. Ehlmann is a scientist at the Jet Propulsion Laboratory and an assistant professor at California Institute of Technology. Grotzinger is project scientist, Mars Science Laboratory and California Institue of Technology. NASA has moderators (far left) for all conferences, usually drawn from their public relations staffs.


.

KSC Launch Equipment Test Facility is a rarely seen place because testing is often going on here, and testing can be hazardous. These days the facility has many fewer people, including only one remaining government NASA employee.


.

Tests are carefully studied and controlled from this room. This is the Control Room in the Launch Equipment Test Facility.


.

Orion, which looks like an Apollo capsule on sterioids, is supposed to be the next generation NASA space vehicle. As with Apollo, this vehicle is meant to travel deeper into space than low earth orbit where the shuttle and the International Space Station traveled. It is hoped that Orion can land on an asteroid, the Moon or even Mars. Until late 2012 it was, however, a capsule without a rocket or a mission. This building is known officially as "The Checkout Building for Orion" and has been extensively repurposed for its earlier uses.


.

The shuttle;s Canister Rotation Facility now houses the Orion escape mechanism. After the deaths of the Columbia astronauts on STS-107 great re-design effort was put into affording future astronauts more opportunities to survive. How to escape and survive an accident involving Orion is being studied in this building.


.

The escape mechanism would pull the Orion capsule away from the rocket and allow it to land by parachute on water or land. Escaping quickly enough is no simple matter either technologically, or for the astronauts themselves. The G-force required to escape is 15 Gs, a gravity force that the human body can only endure about three seconds. By contrast Apollo subjected Astronauts to 6-Gs and the Shuttle to 3-Gs.
