This is no small feat! To ensure NASA’s Space Launch System rocket is ready for Exploration Mission-1, the first integrated flight that will send the Orion spacecraft beyond the Moon, engineers are performing a series of tests at NASA’s Marshall Space Flight Center in Huntsville, Alabama. Watch as crews load the 149-foot (45.4 meters) liquid hydrogen tank structural test article, the largest piece of structural test hardware for the core stage of SLS, into Test Stand 4693 on Jan. 14. Dozens of hydraulic cylinders in the test stand will push and pull on the tank to simulate the stresses and loads it will endure during liftoff and flight. Test Stand 4693 is one of the newest test stands at Marshall, and the liquid hydrogen structural test article is the first piece of hardware to be tested in the stand. 🚀 Credit: NASA/Tyler Martin #nasa #spacelaunchsystem #sls #rocket #engineering #technology #building #testing #exploration #space #explore #deepspace #msfc #moontomars #timelapse
