A New Logistics System for the 'Right Stuff'


Hi everyone! We’re here at Michoud Assembly Facility waiting to sail with ET-134 to the Kennedy Space Center. Thought I’d share with you a little history about how NASA developed the logistics system to move and support all this heavy, outsized spacecraft hardware.

When the space program kicked into high gear in the early 1960s the equipment necessary to move the very large components of spacecraft did not exist. In fact, the lack of necessary equipment almost became a limiting factor when preparing spacecraft designs and considering how to move them to launch sites, the primary location being Kennedy Space Center, Fla.

and Saturn V vehicles between the Marshall Space Flight Center; the  Michoud Assembly

An agency-level logistics office was created at NASA Headquarters in Washington to orchestrate and coordinate a complex set of requirements based on a new and developing program, the Saturn/Apollo Program, and very geographically dispersed set of players, including various NASA centers, test sites, launch sites, suppliers, contractors, and manufacturers; an amazing challenge.

Spacecraft could be built, but now they had to be moved. In the early 1960s Marshall Space Flight Center developed its own logistics management office and began developing plans for a “fleet” of specialized transporters to move the “right stuff.”

Eventually, with assistance and vessels from the U.S. Navy, NASA developed its own ocean-going fleet of seven barges capable of transporting most of the components of the Saturn/Apollo program from home bases to Kennedy Space Center for launch operations.

A smaller fleet of two oversize and heavily modified aircraft known as the Super Guppy and the Pregnant Guppy were procured for movement by air of Saturn F-1 engines, lunar modules and S-IVB stages.

Also, NASA made use of the railroads for moving Saturn propellants and even U.S. Army CH-47 helicopters to move large components from long distances for testing at Marshall.

Center’s Launch Complex 39 area. Behind the locomotive car is the Vehicle Assembly
Building. The train is hauling solid rocket booster segments from the STS-122
mission. After a mission, the spent boosters are recovered, cleaned, disassembled,
refurbished and reused. After hydrolasing the interior of each segment,
they are placed on flatbed trucks and individual booster segments are transferred
to a railhead located at the railroad yard. Credit: NASA

The Space Shuttle Program inherited significant experience and a well-oiled logistics machine from the Saturn Program. Shuttle components are moved by a wide variety of outsized transporters just as in the days of Saturn/Apollo. 

Today, components that make up the solid rocket motors (segments and aft exit cones) are transported cross-country via rail beginning in Utah where they are manufactured. With the help of multiple railroad companies, these components typically spend less than two weeks riding over the rail before arriving at the Kennedy Space Center. Once the components are offloaded, assembled, and ultimately flown in space, they are recovered, disassembled, inspected, and ultimately the segments are transported back to Utah on the same rail that brought them to Kennedy. At this stage in the process the hardware is refurbished and made ready for future flight opportunities.  Solid rocket booster components (forward assemblies, aft skirts) are manufactured at the Assembly and Refurbishment Facility at KSC and transported via ground support equipment over the Kennedy road system to the respective Kennedy facilities where these components are integrated with the solid rocket motor segments. Solid rocket booster hardware and solid rocket motor hardware, when integrated together, make up the space shuttle reusable solid rocket booster. Essentially, NASA is a railroad man as well.

External tanks such as ET-134, as you know already, move by barge and towing ship from New Orleans to Kennedy Space Center over water and space shuttle main engines move by truck. Some NASA equipment, such as specialized cargo or payloads for the International Space Station are moved by Super Guppy, stationed at Ellington Field in Houston, Texas.   

The space shuttle orbiter flies everywhere it goes, except for short distances over ground at Kennedy. If the orbiter has to land away from Kennedy due to weather, such as at Edwards Air Force Base, Calif., a special Boeing 747 pulls up and flies the orbiter back to Kennedy “piggy-back” style in just a few days.

Future space program hardware will likely make use of this same or similar means of transportation for movement from point of origin to the Kennedy Space Center for launch operations. 

Liberty Star’s mission to tow ET-134 to Kennedy is essentially part of a bigger NASA logistics operation.

It has been said that logistics is everything. It may be. You simply have to have the “right stuff” at the right place at the right time…to make a difference.

  1. Except for the shuttle transport, this is because of a government mandate to involve every state in the shuttle program, not a physical requirement.

  2. Thanks for the great blog. Very informative, didn’t know about NASA’s ocean or train connection. Bon voyage, and keep us updated.

  3. Wow, this has to be an incredible journey. It’s amazing to me just how comprehensive the whole project is. Sort of puts the size and magnitude of the rockets in space in perspective when you actually see what even a “piece” of it looks like when relative to modern day water transportation methods which are “huge” themselves.

    When I think of NASA, I think of all the incredible additional benefits that mankind receives from their efforts that I think most people aren’t even aware of or follow, such as….better water purification on earth, weather satellites to save lives, safer commercial airflights to save lives, and many other areas to help indirectly learn how mankind on earth can become a better and safer place, which we all desire. I mean…how can we understand mankind on earth if we don’t understand “where we came from”, from a scientific standpoint that is. Everything must directly or indirectly be assocaited with each other, so I certainly hope projects like these are viewed as a step closer toward learning about mankinds’ future prosperity. Are there other options for defense and health care solutions out there we haven’t tapped yet, but could save millions of lives. Wow.

    Thanks for sharing this great step by step story or your incredible journey. Great photos too!
