TEST STAND 4697 WILL SUBJECT THE 196,000-GALLON CRYOGENIC LIQUID OXYGEN TANK IN THE MASSIVE CORE STAGE OF NASA'S SPACE LAUNCH SYSTEM TO THE TREMENDOUS FORCES IT WILL ENDURE IN LAUNCH AND FLIGHT.

ON MARCH 4, CREW MEMBERS READIED A 900-POUND STEEL BEAM TO "TOP OUT" TEST STAND 4697, WHICH IS UNDER CONSTRUCTION TO TEST THE SPACE LAUNCH SYSTEM LIQUID OXYGEN TANK AT NASA'S MARSHALL SPACE FLIGHT CENTER.

This collection of photos shows the steps NASA engineers took to lift the final structural test article for NASA’s Space Launch System (SLS) core stage into Test Stand 4697 at NASA’s Marshall Space Flight Center in Huntsville, Alabama, July 10, 2019. The liquid oxygen (LOX) tank is one of two propellant tanks in the rocket’s massive core stage that will produce more than 2 million pounds of thrust to help launch Artemis 1, the first flight of NASA’s Orion spacecraft and SLS, to the Moon. The nearly 70-foot-long liquid oxygen tank structural test article was manufactured at NASA’s Michoud Assembly Facility in New Orleans and delivered by NASA’s barge Pegasus to Marshall. Once bolted into the test stand, dozens of hydraulic cylinders will push and pull the tank, subjecting it to the same stresses and forces it will endure during liftoff and flight, to verify it is fit for flight.

Photo shows how the Space Launch Sysetm (SLS) rocket liquid oxygen tank failed during a structural qualification test at NASA’s Marshall Space Flight Center in Huntsville, Alabama. The photos show both the water flowing from the tank as it ruptured and the resultant tear left in the tank when it buckled during the test. Engineers pushed the liquid oxygen structural test article to the limits on purpose. The tank is a test article that is identical to tanks that are part of the SLS core stage that will produce 2 million pounds of thrust to help launch the rocket on the Artemis missions to the Moon. During the test, hydraulic cylinders were then calibrated and positioned along the tank to apply millions of pounds of crippling force from all sides while engineers measured and recorded the effects of the launch and flight forces. For the test, water used to simulate the liquid oxygen flows out of the tank after it ruptures. The structural test campaign was conducted on the rocket to ensure the SLS rocket’s structure can endure the rigors of launch and safely send astronauts to the Moon on the Artemis missions.
