Marshall Space Flight Center is a space nerd’s dream! How can you go wrong with rocket engines, gigantic test stands, and amazing testing facilities that all help the NASA Space Launch System (SLS) rocket make it into deep space? You can’t! Not with Huntsville being one of the World’s Smartest Cities and this tour proves it.
I was able to be fortunate to be on a pre-BEX tour to the Marshall Space Flight Center at Redstone Arsenal while at the TBEX Conference. This tour is the same gold star treatment that they give Senators when visiting this facility. They test large-scale structures to make sure they can handle the loads that are seen in space. Currently, they are performing the testing for the Space Launch System rocket. Understanding the magnitude of this project, look at the person that is to scale at the bottom left of the rocket photo below. Can you find him?

Marshall Space Flight Center
Our first stop is the George C. Marshall Marshall Space Flight Center building where we get an excellent introduction from Todd May. NASA’s mission is the scientific research in and exploration of space for peaceful purposes. This facility is named after George C. Marshall who was a 5star general in WWII and a Secretary of State. He initiated the Marshall Plan to rebuild Western Europe after the war and won the Noble Peace Prize. It seems fitting for a man that was dedicated to peace has this agency named for him.
Space Launch System
We then get an introduction to the Space Launch System (also known as SLS) by Tim Flores. This rocket is powered by four RS-25 engines firing simultaneously and will provide 2 million pounds of thrust while working in conjunction with a pair of solid rocket boosters. This mission to deep space is named EM-1 (Exploration Mission-1).
This is all needed to get this rocket, which is larger than the Statue of Liberty, into deep space. The SLS consists of Orion at the top where the cargo (Secondary Payloads) and eventually astronauts will be. There are modified solid rocket boosters from the shuttle program, RS-25 engines, and the 1st cylinder section is the liquid oxygen tank being tested (inner tank).
Outside of the George C. Marshall building, are three engines. Massive engineering feats of scientific ingenuity. Even with my degree in Mechanical Engineering, I was astounded by the scale of these engines. When they tested the Saturn V rocket F1 engine (seen in the center below) in the past, they did it dynamically. They fired five F1 engines at once, and it blew out windows in downtown Huntsville and registered on the Richter scale hundreds of miles away. Because of this test, they only test the engines statically now. NASA does not reuse the SLS engines like the space shuttle program, so, there will be many more tests in the future.
Advanced Manufacturing Center
Kim Henry, public relations, is our fabulous tour guide for the afternoon making sure we get from one building to another. Love her enthusiasm for her job!
The 3-d printing area was neat to see. Every part the engineers are making is for the SLS rocket. I even got to see a 3-d printing in development. It is fascinating to watch as a layer is added then burned and then the process repeats. They even have larger printers for the bigger rocket components.
Secondary Payloads
After the explanation of what Secondary Payloads are, we donned our NASA gear (we dubbed it the NASA raincoat since it was raining out). The ring that houses these eleven cubes just came in so; we got to see the actual SLS part. I can’t believe I am seeing a part of the Space Launch System that will be launching in 2019 and will be traveling to deep space and be orbiting the moon.
Payload Operations Center
The people who work at the Payload Operations Center manage all the operations for the science and research experiments aboard the Space Station. They direct the communications between the Space Station and the researchers around the world. They also coordinate the payload activities of NASA’s International Partners. Each flag on the ceiling of the Center are countries that work with the International Space Station.
What I enjoyed was the time to get to know some fellow TBEX travel bloggers before the conference began. My new friend, Leslie Gibbs, and I connected right off the bat. Didn’t matter that her family lives in Atlanta and I’m from Michigan. Our shared passion for travel is what brought all of us here to Huntsville in the first place.
Test Stands
We finished our tour, riding the bus to view the test stands. First stop is the National Historic Landmark of the Redstone first test stand. The second test stand is the S1C test stand that was used for the Saturn V engines (mentioned earlier). The third is the 65-foot tall Space Launch System Structural Load Test Stand. The last and the biggest is the SLS Test Stand 4693 which will be used for structural loads testing on the liquid hydrogen tank for the core stage of NASA’s Space Launch System. Test Stand 4693 is 21 stories tall and consists of 7 million pounds of steel. You can see these test stands on the Redstone Arsenal Space Rocket Center bus tour.
All of the components of the Space Launch System have been made. The next step is to start installing all the parts and test them. They are being transported here on barges, trucks, and planes. This is an incredible tour to see everything that goes into launching the world’s most powerful rocket that will be launching into deep space in 2019.
