Teamwork makes the dream work. Yesterday the fourth and final structural test article for NASA’s Space Launch System (SLS) core stage was unloaded from barge Pegasus at NASA’s Marshall Space Flight Center in Huntsville, Alabama. The nearly 70-foot-long liquid oxygen (LOX) tank structural test article was manufactured at NASA’s Michoud Assembly Facility in New Orleans and is structurally identical to the flight version. Next, crews will load it into a test stand at Marshall for critical testing. The liquid oxygen tank is one of two propellant tanks in the rocket’s core stage that will produce more than 2 million pounds of thrust to help launch Artemis 1, the first flight of the Orion spacecraft and SLS rocket, to the Moon. Testing ensures the success, not only of the initial flights, but also those SLS flights that will carry American astronauts to the Moon and ultimately to Mars.
