Archive for the ‘crawler transporter’ Category

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.

Hangar to VAB to Launch to Space & back

Shuttles always returned on landing to one of four hangars which were offically known as Orbiter Processing Facility 1, 2, 3 and 4. In the OPF the shuttle was serviced, repaired as necessary and readied again to fly in space.


.

Movement of the shuttle first was from the OPF to the Vehicle Assembly building several hundred yards away. This movement was called "the rollover" and took several hours.


.

The shuttle was transported on a carrier that was driven by a driver. Entering the VAB the shuttle was in the Transit Aisle, a room which extends to the top of the VAB more than 500 feet and 40 stories high.


.

Carol Anne Swagler's Shuttle photograph from a 16th floor catwalk in the VAB. As lifting of the shuttle begins, the shuttle seems to takes flight. Once she is upright, she hangs above the Transit Aisle for hours.


.

On the Transit Aisle, the shuttle is harnessed and then turned on end. It is allowed to hang there for hours until it completely settles and stops swaying. Then it is slowly lifted 500-feet to the ceiling on the VAB.


.

Pete Crow's Shuttle photograph showing the Atlantis after being moved directly over the 5-story high Crawler/Transporter in VAB High Bay 1. This photo was taken from a catwalk on the 16th floor of the VAB.


.

The most difficult and occasionally time-consuming step in the "Lift (the shuttle) to Mate (the shuttle with the Transporter/Crawler) is lowering the shuttle precisely onto the Crawler to enable its being secured onto the Crawler/Transporter. Once the shuttle is secure, the Crawler begins moving out of the VAB, as shown here, toward the Launch Pad at the rate of 1 mile and hour.


.

Once outside the VAB, the Crawler turns onto the Crawler way, two strips on Alabama river rock separated by a green center median. The Crawler way leads to both Pad 39-A and Pad 39-B, branching several miles down the Crawlerway. In the final missions only Pad 39-A was used. Pad 39-B was torn down and demolished in May and June 2011 to begin to prepare it for Constellation, the next US manned space program. President Obama canceled Constellation after millions had been spent, but the outcry was so great he reinstated it. More money was spent and then Mr. Obama canceled it again. All that remains is a 1960s-esq capsule that resembles Apollo called Orion. Orion is a capsule without a rocket to get it into space and no one will say when a rocket for it will be announced.


.

The Crawler is five stories high. To gauge the size of it look for the man in this picture besides the track (bottom center). For many years NASA invited selected members of the press to walk with the Crawler from the VAB to the Pad. As the program neared an end, the shuttles were commonly moved at night and it was deemed too dangerous to allow the media to walk with the shuttle any longer.


.

Carol Anne Swagler, Grove Sun Daily, walks far ahead of the shuttle and stands on one of the twin rock highways on which the shuttle traveled. The Crawler and shuttle were so heavy the rocks on the highway were crushed each time and had to be replaced. Nothing about the shuttle program was easy or inexpensive.


.

Pete Crow and the Shuttle Atlantis days before her final July 8, 2011 launch. Once at the Pad, the payload for the shuttle is brought to the pad and lifted up onto the Rotating Service Structure, directly behind Pete Crow. The payload for STS-135 is in the white rectangular box over his left shoulder. When ready, the shuttle's payload doors are opened and the RSS is rotated until it covers the shuttle. The payload is then secured in the shuttle's bay.


.

The RSS remains mated with the shuttle until about 18 hours before launch. Then it is retracted -- rotated more than 90-degrees leaving the shuttle alone on the pad, and ready to be fueled about 9 hours before launch.


.

The RSS has been fully retracted and the shuttle is ready to be launched. This is Endeavour awaiting launch on STS-134, the second to last shuttle mission. Retraction is a popular press event unless it rains. Few photographed the retraction of the final shuttle mission, STS-135, on the afternoon of July 7, 2011 because the time for retraction was repeatedly shifted due to weather, and because weather at the Pad was often a driving rain and it was muddy. Retraction was more easily enjoyed by watching it on NASA-TV from the comfort of the Pad 39 Press site.


.

Kennedy Space Center adjoins a wildlife sanctuary, Merritt Island, on the eastern shore of the Atlantic Ocean. Dawn here is often beautiful as it was on the blustery morning of July 8, 2011, when Pete took this photograph of the Atlantis on Pad 39-A.


.

Pete Crow shuttle Atlantis photograph from the roff of the Vehicle Assembly Building seconds after lift-off. There are only a handful of photographers allowed on the VAB roof for safety reasons, but Seine/Harbour® and The Grove Sun, Grove, Oklahoma, were granted two of the less than 40 spaces on July 8, 2011.


.

This is Endeavour being launched on STS-134 on May 16, 2011. The view is 22 seconds into the launch and was taken at the Media Press site. It shows a strikingly different perspective than the picture directly above taken from the VAB roof. Once launched the astronauts are in subjected to three+ G's (three times the weight of gravity). It doesn't last long. Eight minutes after launch the shuttle is over Africa and in space. And the astronauts are weightless.


.

Later shuttle missions lasted 12 to 14 days. The shuttle has to watch its energy reserves which drive the electrical which drives its computers. Generally, the shuttle undocks two days before landing from the International Space Station (ISS) then re-configures its orbits for landing in Florida. Landing begins with a de-orbit burn on the other side of the world, commonly over the Indian Ocean. Once the de-orbit burn is exectued about 60 minutes from landing, the shuttle has no where else to go except to the tiny Shuttle Landing Facility (runway) at Kennedy Space Center. This photo, taken by Pete, is of the final landing of Discovery and was taken on the northern end of the runway.

The Crawler transports the shuttle to the launch pad after being mated with the shuttle in the Vehicle Assembly Building. Mating takes about ten days. This Crawler, one of several, is parked in a storage facility on the Crawlway that leads to Pads 39-A and 39-B.

The Crawler is about five stories high and is driven by one person with a whole lot of help. Spotters walk ahead of the Crawler when a Shuttle is mated to the Crawler and the Crawler is transporting the shuttle to the launch pad. A second parking facility for Crawler parking is adjacent to the three Orbiter Processing Facilities (OPF = hangar) and the Vehicle Assembly Building (VAB).

The final trip for the Crawler transporting a shuttle, the Atlantis, from the VAB to Launch Pad 39-A was on the night of May 31-June 1, 2011. Unless weather forces a return of the Atlantis back to the VAB for safety, the Crawler will never be used again to transport a shuttle, but just as the Crawlers found life after the Apollo Moon capsules and rockets, so too they will likely soldier on.

In case you’d like to buy one to drive around your neighborhood, you will want to kick the tires wearing steel boots. Those aren’t tires; the Crawler is driven, like tanks, by tracks.

This photograph was taken by Carol Anne Swagler on May 17, 2011.
